[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing method and a coating material manufacturing method for manufacturing a colored aggregate-containing coating material containing a colored aggregate as a main component, which is used as a finishing material for wall surfaces and ceilings of building structures. In this case, the present invention relates to an apparatus and method that can be used for mixing colored aggregate.

[0002]

2. Description of the Related Art Most colored aggregate-containing coating materials, which are mainly used as finish materials for wall surfaces and ceilings of building structures, have a relatively high viscosity paste (paste) or slurry (liquid). And a suspension of solid particles).

Since the coating material has a relatively high viscosity, it does not sag even after being applied thickly, and it is possible to easily obtain a heavy finish having a design feeling with unevenness in height. Further, it is possible to obtain a coated surface such as a granite-like or marble-like surface by using a plurality of kinds of the colored aggregate-containing coating materials. In addition, just before coating, this relatively high-viscosity slurry-like coating material is diluted with a diluent to reduce the coating material viscosity, so that a flat and colorfully painted surface that expresses the color tone of colored aggregates. Can be obtained.

The colored aggregate-containing coating material is often obtained by mixing a liquid raw material containing a synthetic resin and the colored aggregate using a mixing device such as a mixer, and filling the container with a container such as a can for coating. It is transported to a place where it can be seen and used for painting.

[0005]

However, since the colored aggregate-containing coating material is in the form of a slurry having a relatively high viscosity, it takes a long time to manufacture the coating material.

[0006] Further, since the particle size width of the colored aggregate which is a coating material component is relatively narrow and the particle size of the colored aggregate is small, it may be difficult to carry out pressure feeding by a pump such as a pump, and thus filling of the coating material It often takes time.

Further, the highly viscous, slurry-like colored aggregate-containing coating material adhering to the wall surface of the manufacturing pot may be washed and discarded when the manufacturing pot is washed. It also resulted in more material loss.

In the manufacturing work and the filling work of the colored aggregate-containing coating material as described above, it is often impossible to efficiently produce the colored aggregate-containing coating material. Furthermore, the colored aggregate-containing coating material is further produced. There are many losses.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below. The method for producing a colored aggregate-containing coating material according to the present invention comprises, in a coating material storage container, one or two or more types of liquid raw materials and one or two or more types of colored aggregates, the weight or It is to fill while controlling by volume.

First, the colored aggregate is used for imparting a color tone to the coating film formed by the coating material.
The colored aggregates are colored aggregates other than transparent aggregates made of transparent glass or the like, and there are crushed colored natural stones. There are also colored aggregates such as artificially colored crushed stones and ceramics and industrially produced ones.

The crushed colored natural stones include marble crushed particles,
Examples include silica sand and natural fine gravel. Furthermore, lightweight aggregates such as shirasu balloon, perlite, and foamed crushed glass can be used.

The colored aggregates obtained by artificially coloring crushed stones include crushed colored natural stones, silica sand, cold water sand, ceramic crushed particles, and carbon black and red iron oxide for the lightweight aggregates. There are a method of coating with a coating material to which a pigment such as oak or phthalocyanine blue is added, or a method of coating with a glaze.

Industrially produced colored aggregates include glass beads in which glass is formed into a substantially spherical shape, and plastic beads in which synthetic resin such as an acrylic resin is formed into a substantially spherical shape. These can be colored from the inside in the process of manufacturing the aggregate.

Further, a light-storing component can be added to the artificial aggregated colored aggregate and the paint, glaze and the like which are the coloring components of the industrially produced colored aggregate. Furthermore, it is possible to obtain a colored aggregate that stores light by adding a light storing component to glass or synthetic resin. In this way, the phosphorescent aggregate can be obtained and can be contained in the coating material as a colored aggregate.

Compared with crushed colored natural stone, artificially colored colored aggregates and industrially produced colored aggregates have stable particle sizes and color tones, and thus were used as aggregate-containing coating materials. The color tone is stable and easy to use. In particular, artificially colored silica sand, cold water sand, and ceramic crushed particles are easily available, have excellent miscibility with the liquid raw material described below, and are easily mixed, and thus are preferably used.

Silica sand contains silicon dioxide as a main component, and there are a granular one in a natural state typified by river sand and sea sand, and a granular one obtained by crushing silica stone. Cold water sand is mainly composed of calcium carbonate, and there is, for example, one in which cold water stone is crushed to adjust the particle size. The ceramic crushed particles are obtained by crushing ceramics and are used after adjusting the particle size. These aggregates can be appropriately selected and used.

The liquid raw material has a synthetic resin as a main component, and various additives are added if necessary. The synthetic resin used as the liquid raw material is a binding material for binding the colored aggregates to each other and for adhering the coating material to the article to be coated. Further, in order to form a coating film making the best use of the color tone of the colored aggregate, it is necessary that the dry film obtained from the synthetic resin alone be transparent and transparent to light.

The synthetic resin is obtained from silicone resin, acrylic resin, epoxy resin, urethane resin, polyester resin or the like, and may be used alone or in combination of two or more kinds. The form of these synthetic resins may be a synthetic resin emulsion dispersed in water using an emulsifier, or a synthetic resin emulsion dissolved in an organic solvent or dispersed in a weak solvent. The synthetic resin emulsion is preferably used because it has excellent miscibility with the above-mentioned colored aggregate, can easily increase the viscosity of the colored aggregate-containing coating material, and is easy to handle.

Examples of various additives include thickeners, defoamers, wetting agents, dispersants, preservatives, anti-algal agents, and high-boiling solvents. The thickening agent can prevent the colored aggregate in the coating material from settling, and can improve the coating workability when coating the coating material. The defoaming agent adjusts the amount of bubbles in the coating material.

The wetting agent improves the wettability of the surface of the colored aggregate and improves the miscibility between the liquid raw material and the colored aggregate. Further, it is intended to improve the wettability with the object to be coated at the time of coating.

The dispersant improves the dispersibility of the colored aggregate. The antiseptic agent is for sterilizing various bacteria in the coating material to prevent spoilage of the coating material, and the algae fungicide is for preventing algae and mold which are formed by the coating material and are generated in the coating film. is there.

The high boiling point solvent serves as a film-forming aid for improving the film-forming property of the coating film in the process of forming the coating film with the coating material, an antifreezing agent for preventing the coating material from freezing, and the like. Is used.

The coating material storage container is used for storing and transporting the colored aggregate-containing coating material and for manufacturing the colored aggregate-containing coating material. This container is made of steel or plastic, or in the form of a bag or a bag made of vinyl, a box of waterproof paper, or a box made of vinyl inside a cardboard box. A general shape is suitable for storing, transporting and manufacturing colored aggregate-containing coating materials, such as those containing a water-impermeable bag or those with a coating that also forms a water-impermeable layer inside the box. good.

The container may have any size as long as it can store the required colored aggregate-containing coating material. Many of the coating material storage containers are provided with a discharge port for discharging the coating material on the upper surface of the container or on a side surface near the upper surface, and the discharge port can be closed with a lid. Is.

Next, a method of filling the colored aggregate and the liquid raw material will be described. The filling method is to fill each of the liquid raw material and the colored aggregate into the paint storage container while controlling the volume or weight. Further, the filling can be performed for each paint storage container or continuously. The liquid raw material and the colored aggregate are filled from the discharge port provided in the coating material storage container.

As a method of filling while controlling the volume, it is possible to continuously fill the colored aggregate and the liquid raw material by using a plurality of positive displacement pumps capable of delivering a constant volume. Therefore, it is possible to continuously produce the colored aggregate-containing coating material, and it is also possible to produce the colored aggregate-containing paint for each paint storage container.

It is preferable that the positive displacement pumps are prepared in a number corresponding to the number of liquid raw materials and colored aggregates. In other words, if the types of colored aggregates, such as the number of colors of colored aggregates, increase, a positive displacement pump suitable for it will be needed. This means that the coating material mainly composed of colored aggregate has a color tone of colored aggregate,
Different types of coating materials will be produced due to differences in particle size etc.

As a method of filling while controlling by weight, the weights of the colored aggregate and the liquid raw material, which are necessary in advance, are separately prepared,
It is measured by a measuring device such as a scale, and the measured product is filled. According to this method, a colored aggregate-containing coating material can be produced for each paint storage container.

In the method for producing a colored aggregate-containing coating material by this method, the production of a colored aggregate-containing coating material and the production such as filling can be efficiently performed, and in particular, the production in the case where the coating material amount is small It can be performed efficiently, and there is no loss of coating material due to production.

The weight measurement of the colored aggregate is carried out for each type of the colored aggregate, and the colored aggregate is filled for each colored aggregate, or the colored aggregates measured for each type are collectively packed. It is possible to fill them all together, and the packing efficiency is improved, which is preferably used.

A colored aggregate-containing coating material is produced from the liquid raw material and the colored aggregate filled as described above. The produced colored aggregate-containing coating material is agitated with a mixer or the like immediately before using the coating material, and coating is performed in a mixed state.
During this stirring, the viscosity of the colored aggregate is also adjusted. In many cases, a diluent suitable for the coating material is added and stirred to adjust the viscosity of the coating material.

The liquid raw material and the colored aggregate are preferably filled at the same time. By filling them at the same time, they are in a state where they are mixed well and the stirring of the colored aggregate-containing coating material just before use becomes easy. Furthermore, it is more preferable to fill the same time. By filling for the same time, the liquid raw material filled in the coating material storage container and the colored aggregate are in a state of being mixed well evenly, and stirring immediately before using the colored aggregate-containing coating material. But it will be easier.

It is preferable that at least one or more of one or more kinds of liquid raw materials and one or more kinds of colored aggregates be pressurized and filled. At least one kind of the liquid raw material and the colored aggregate is pressurized and filled, so that the injection pressure at the time of filling the pressurized one causes
The liquid raw material and the colored aggregate collide with each other by colliding with the wall surface, the bottom surface, and the upper surface in the coating material storage container, and the liquid raw material and the colored aggregate,
The more evenly mixed state is achieved, and the stirring of the colored aggregate-containing coating material just before use is further facilitated.

In such a case, it is preferable that the coating material storage container is in a closed state. This closed state means that the discharge port provided in the coating material storage container for filling the liquid raw material and the colored aggregate is made as small as possible, and the portion other than the filling portion is closed. If not in a closed state, the pressurized liquid raw material and colored aggregate may spout out of the container from a place other than the filling place.

As the above-mentioned state of pressurization, there are a method of applying pressure to the air around the liquid raw material itself or the colored aggregate, and a method of using compressed air to eject. This pressurizing method is not particularly limited, and any pressurizing machine or device can be used.

When the coating material storage container is filled with one or more kinds of liquid raw materials and one or more kinds of colored aggregates while controlling the weight or volume for each kind, the filling. It is desirable to mix using a mixer during or after filling. By mixing with a mixer, the colored aggregate-containing coating material before use is in a state in which the liquid raw material and the colored aggregate have already been mixed, so stirring immediately before use becomes easy, and in some cases Depending on the case, stirring may be unnecessary.

The mixer includes a rotary vane type mixer, a vibration type mixer, a gyro mixer, etc. Further, compressed air is filled in a coating material storage container or introduced into a liquid raw material and a colored aggregate being filled. There is a mixer that mixes by the force of the air. A rotary vane mixer is a mixer that uses an electric motor, and a rod-shaped shaft of an appropriate length projects from the rotary shaft of the motor.
A blade for stirring is provided at the tip of the shaft. There is a method in which a stirring blade of a rotary blade type mixer is inserted into a coating material discharge port provided on the upper surface of the coating material storage container and the mixture is performed.

The vibrating mixer is a mixer in which raw materials before mixing are enclosed in a container, and the container is subjected to vertical reciprocating or lateral reciprocating vibration to mix the contents.

Further, the gyro mixer is a mixer for rotating and revolving the shaft holding the coating material storage container, and applying the force of horizontal rotation and vertical rotation to the liquid raw material and the colored aggregate. By mixing with this gyro mixer, unlike the case of using a rotary-blade mixer, there is no such thing as a mixer to wash, so there is no waste water associated with cleaning, so there is no need to install a waste water treatment facility. . Further, since the colored aggregate-containing coating material attached to the rotary vane mixer is eliminated, the weight of the coating material does not change.

For the above reasons, it may be preferable to use a gyro mixer for mixing. Furthermore, when introducing compressed air into the coating material storage container or introducing it into the liquid raw material and the colored aggregate that are being filled, and mixing by the force of the air, compared with a rotary blade mixer or a gyro mixer. The friction between the colored aggregates and the friction between the colored aggregate and the inner surface of the coating material storage container can be mixed with little.

When there is a large amount of friction between the colored aggregates, the friction may break the colored aggregates or scrape the surface thereof to change the particle diameter of the colored aggregates. When a colored aggregate in which the surface of the aggregate is colored is used as the colored aggregate, the colored layer may be damaged and the color tone may change.

Further, in many cases, the colored aggregate-containing coating material contains a synthetic resin emulsion as a main component,
Further, the coating material storage container used for storing the colored aggregate-containing coating material is made of steel, and the inner surface of the container is subjected to a rust preventive treatment for preventing the generation of rust. The rust-proofing treatment is often provided with a coating layer for coating with a paint having a rust-proofing effect.

Therefore, the friction between the colored aggregate and the inner surface of the coating material storage container may damage the coating layer having an anticorrosive effect, and rust may be generated from the scratch. For the reasons described above, it may be preferable to introduce compressed air into the liquid material raw material and the colored aggregate that are being filled or are being filled in the coating material storage container and mix them by the force of the air.

The colored aggregate and the mixing ratio of the colored aggregate and the liquid raw material in the method for producing the colored aggregate-containing coating material configured as described above will be described. The particle size of the colored aggregate is 0.
90% of all colored aggregates in the range 037-2.0 mm
It is preferably within%. If the thickness is less than 0.037 mm, the coating film formed by the coating material may be cracked due to shrinkage, or the coating film may not have a colorful feeling due to the colored aggregate and may lack design. On the other hand, when it exceeds 2.0 mm, the coating film formed by the coating material is rough and may be lacking in design.

Further, in the method for producing a coating material containing a colored coating material of the present invention, 0.037 to 0.300 m within the particle size range described above.
When the colored aggregate of m is 25% or more in the total weight of the colored aggregate, there is an effective effect as compared with the conventional manufacturing method. That is, when the colored aggregate having a particle size range of 0.037 to 0.300 mm accounts for 25% or more of the total weight of the colored aggregate, the colored aggregate which is one of the main components of the colored aggregate-containing coating material. Since the particle size of the material is small and the particle size width is narrow, it is often difficult to carry out pressure feeding by a pump such as a pump, and it takes time to fill the coating material. Further, since it is a paste having a relatively high viscosity, it often takes time to manufacture the coating material, and the coating material loss due to the production is large.

However, according to the present invention, when the colored aggregate having the particle size range of 0.037 to 0.300 mm is 25% or more in the total weight of the colored aggregate, the production and filling of the coating material are performed. It is possible to efficiently perform the production including, and the coating film formed by the coating material has a variety of feelings and has good designability.

The mixing ratio of the colored aggregate and the liquid raw material is 1
It is preferably in the range of 0: 1 to 1: 1. When the amount of colored aggregate is more than 10: 1, the produced colored aggregate-containing coating material may have poor fluidity and may be difficult to apply. When the amount of colored aggregate is less than 1: 1, the viscosity of the coating material at the time of coating becomes low, which may make the coating difficult.

It is possible to mix only a plurality of types of colored aggregates prior to mixing with the liquid raw material. Conventionally existing mixers suitable for mixing aggregates or granular materials are roughly classified into a container rotating type and a container fixed type, and examples of the former include a cylindrical type mixer, a double cone type mixer, and a cubic cube. Type mixers, twin cylinder type (V type) mixers, the latter of which are ribbon type mixers, screw type mixers (there are horizontal type and vertical type), fluidized type mixers, rotary disk type mixers. , There is an air flow type mixer. dd

As a novel apparatus suitable for mixing aggregates, an apparatus having the simple structure described below was invented. Although it is a device suitable for mixing aggregates, it is possible to mix powders other than aggregates.

The mixing device comprises a plurality of sets of funnel-shaped collecting elements, conical dispersing elements, and a cylindrical outer frame that covers these dispersing elements and collecting elements. When grasped as a mixing method, by dropping the powder and granules from the conical pointed tip to disperse them radially, and repeating the motion of gathering them by the funnel-shaped powder and granule receivers a plurality of times,
This is to mix powder and granular material. In the specification, a conical dispersion element that disperses powder particles in the circumferential direction is called a conical dispersion element, and another funnel-shaped particle that is dispersed in the circumferential direction is reconstituted. The element to be assembled is called a funnel-shaped assembly element.

Further, the funnel-shaped collecting element is in close contact with the outer frame, and the conical dispersing element has a space for dropping the granular material between it and the outer frame. With this configuration, the powder or granules that have passed through the conical dispersing element can be sent to the funnel-shaped collecting element in the next step.

Further, the funnel-shaped collecting element and / or the conical dispersing element may be provided with a plurality of convex stripes in the flow path direction of the powdery or granular material. The ridges are provided in the shape of a V shape or an inverted C shape within a range of an acute angle rather than being parallel to the flow path, so that the mixing can be promoted.

As described above, according to this embodiment, the following effects are exhibited. Colored aggregate by filling one or two or more types of liquid raw materials and one or two or more types of colored aggregate in the coating material storage container while controlling the weight or volume for each type. The content-containing coating material can be efficiently produced, the loss of the colored aggregate is small, and particularly, the production can be efficiently performed when the amount of the color-aggregate-containing coating material is small.

By mixing two or more kinds of colored aggregates in advance, when the liquid raw material and the colored aggregates are mixed, there is no unevenness in the colored aggregates, and a colored aggregate-containing coating material with a stable color tone is obtained. Will be produced.

When mixing two or more kinds of colored aggregates, a plurality of sets of funnel-shaped aggregate elements and conical dispersion elements, and a cylindrical outer frame that covers these dispersion elements and assembly elements Premixing by the device results in the production of a colored aggregate-containing coating material with a stable color tone in which the colored aggregate parts are mixed by the device having a simple structure.

Injection of one or more kinds of liquid raw materials, at least one or more kinds of one or more kinds of colored aggregates by pressurization and filling, and the injection of the pressurized ones The pressure causes the liquid material and the colored aggregate to collide with each other by colliding with the wall surface, bottom surface, and top surface in the coating material storage container, and the liquid material and the colored aggregate are more evenly and well mixed with each other. Stirring of the material-containing coating material immediately before use is further facilitated.

Furthermore, by mixing during or after filling, the colored aggregate-containing coating material before use is in a state in which the liquid raw material and the colored aggregate have already been mixed, so that stirring just before use is It may be easier and in some cases stirring may not be necessary. -By introducing compressed air into the colored aggregate in the mixing, the friction between the colored aggregates and the friction between the colored aggregate and the inner surface of the coating material storage container can be mixed with little.

By doing so, the filling efficiency is improved, and the colored aggregate-containing coating material can be produced for each paint storage container.

The liquid raw material and the colored bone filled in the coating material storage container by simultaneously filling one or more liquid raw materials and one or two or more colored aggregates at the same time. As a result, the materials are evenly and well mixed, and it becomes easier to stir the colored aggregate-containing coating material immediately before use.

Since the mixer used when mixing the colored aggregate and the liquid raw material is a gyro mixer, there is nothing to wash such as a mixer, and therefore, waste water associated with the washing is eliminated, so a waste water treatment facility is provided. There is no need. Further, since the colored aggregate-containing coating material attached to the rotary mixer disappears, the weight of the coating material does not change.

The particle size of the colored aggregate is 0.037 to
The thickness of 2.0 mm is 90% or less of all colored aggregates, so that the coating film formed by the coating material may crack due to shrinkage, and the coating film does not have a colorful feeling due to the colored aggregate material. There is no lack of sex.

The particle size distribution of the colored aggregate is 0.037-
In the case where 25% or more of the total weight of colored aggregate is included in the range of 0.300 mm, there is an effective effect as compared with the conventional manufacturing method. In other words, the aggregate grain size is 0.037-0.300 m
When the colored aggregate in the range of m is 25% or more in the total weight of the colored aggregate, the time required for filling the coating material and the time required for the manufacturing operation can be shortened as compared with the conventional manufacturing method. ,
The coating material loss due to production is small.

The mixing ratio of the colored aggregate and the liquid raw material is 1
The range of 0: 1 to 1: 1 facilitates coating with the coating material.

As a device for mixing two or more kinds of colored aggregates, it is composed of a plurality of sets of funnel-shaped collecting elements and conical dispersing elements, and a cylindrical outer frame that covers these dispersing elements and collecting elements. By using the ones, it becomes possible to mix the powdery or granular material containing the colored aggregate only by dropping it by its own weight.

As the above-mentioned device for mixing two or more kinds of colored aggregates, the funnel-shaped collecting element is in close contact with the outer frame, and the conical dispersing element is the space in which the granular material falls between the outer frame and the conical dispersing element. Since the colored aggregate is provided with, it is possible to prevent the colored aggregate from passing through the aggregate element or the dispersing element.

As the above-mentioned device for mixing two or more kinds of colored aggregates, the funnel-shaped assembly element and / or the conical dispersion element has a plurality of convex stripes in the flow direction of the powder or granule. As a result, a lateral force is applied to the fall of the colored aggregate in the apparatus, and the mixing can be promoted.

The mixing method in the device for mixing two or more kinds of colored aggregates described above is such that a plurality of powder particles having different colors and / or particle size distributions are simultaneously supplied to the funnel-shaped collecting element and dropped from the funnel outlet. It is characterized in that the powder particles to be received are received in the center of the conical dispersion element and dispersed radially, and the powder particles can be mixed by utilizing the self-weight drop energy of the powder particles containing the colored aggregate.
