Description

  The present invention is excellent in storage stability, cannot form particles between particles at the time of hydration, has a good iron slip, and has a very good performance after construction, and a plastering material using the same It relates to production kits and mortars.

  For plastering materials such as cement mortar, plaster, plaster, etc., in order to obtain good workability and post-construction performance, the type and amount of various fillers and admixtures to be blended are appropriately determined according to the purpose. And care must be taken to adjust the amount of water added, and sufficient mixing is also required.

  Also, if the filler or admixture with high specific gravity contained in the plastering material is dispersed in water in advance, the filler or admixture will settle and separate due to standing, so we measure the procured material on-site. Then, the work of emptying is performed.

  However, it is not only complicated to determine the type and amount of fillers and admixtures to be blended as appropriate, but the measurement of fillers and admixtures is time consuming. Since it is necessary, pre-prepared products in which only necessary amounts of necessary materials are prepared in advance are sold.

In recent years, DIY (Do it yourself), which tries to paint walls with its own hands, has become popular, and the popularity of pre-prepared products is also increasing.

  However, conventional pre-prepared products need to be mixed with water-based resin and water when used, so they cannot be used in places where it is difficult to procure necessary water such as remote islands and mountainous areas. There is still a problem that water-based resin and water must be measured.

  In addition, conventional pre-prepared products are difficult to mix with powder and water or water-based resin due to wettability, and the particles adhere to each other during hydration, resulting in mako. There is a problem that it is necessary to mix in small amounts using special machines and tools that come in contact frequently.

  On the other hand, there is a product in which cement and aggregate and water are stored in separate spaces in a flexible bag, but there is a problem that storage stability is inferior because a considerably high sealing performance is required. That is, for example, immediately after the cement and aggregate and water are stored in separate spaces, as time passes, water or the like gradually enters the space in which the cement and aggregate are stored, and the cement and aggregate are There is a problem that it hardens.

  The object of the present invention is excellent in storage stability, can be quickly and easily mixed without using a special machine or tool, cannot make particles between particles at the time of hydration, and has an appropriate softness, The present invention provides a gel-like composition for mortar, a plastering material production kit and a mortar using the same, which have good trowel sliding, can be easily wall-coated, and have very good performance after construction.

  Moreover, it is preferable that the gel composition for mortar further comprises any one or more selected from aggregates, diatomaceous earth, water retention materials, and short fibers.

  The first plastering material production kit of the present invention comprises a combination of the gel composition for mortar and a mortar material containing an inorganic binding material.

  In the second plastering material production kit of the present invention, the inside of the packaging container is divided into a plurality of spaces by a separating means, and the gel composition for mortar is accommodated in at least one of the plurality of spaces. And the mortar gel composition containing an inorganic binding material in at least one other of the plurality of spaces, the gel composition for mortar being stored in separate spaces, and The mortar material containing the inorganic binding material can be mixed inside the packaging container by removing or releasing the separation means.

  The plurality of spaces are a first space and a second space, the first space includes the gel-like composition for mortar, and the second space includes an inorganic binder material. , And removing or releasing the separating means, so that the contents in the first space and the contents in the second space can be mixed inside the packaging container. Can be.

  In the plastering material manufacturing kit of the present invention, it is preferable that the inorganic binding material is composed of at least one selected from Portland cement, gypsum, slaked lime, and dolomite plaster. It is preferable that the mortar material further includes any one or more selected from aggregates, diatomaceous earth, short fibers, re-emulsifying powder resin, and water-soluble resin.

  The first mortar of the present invention is obtained by mixing the mortar gel composition and a mortar material comprising an inorganic binder material.

  The second mortar of the present invention is obtained by mixing a mortar gel composition contained in the plastering material manufacturing kit and a mortar material comprising an inorganic binder material.

  If the gel composition for mortar of the present invention or a plastering material production kit using the same is used, the gel composition for mortar has an appropriate hardness when mixed with a mortar material containing an inorganic binder material. The water necessary for obtaining the mortar does not have to be prepared separately, and is particularly suitable for use in places such as remote islands and mountainous areas.

  If the gel composition for mortar of the present invention or a plastering material manufacturing kit using the same is used, it can be quickly and easily mixed without using a special machine or tool. In addition, it is possible to obtain a plastering material having an appropriate softness, good trowel slip, easy wall coating, and excellent performance after curing.

  The plastering material manufacturing kit using the gel composition for mortar of the present invention is excellent in storage stability, and even if it is not used for a long time, components such as cement do not harden. Have advantages.

  The second plastering material manufacturing kit of the present invention can be kneaded inside the packaging container, so that there is an advantage that the powder does not scatter and does not require other containers or stain hands and clothes. .

  Hereinafter, embodiments of the present invention will be described.

  The gel composition for mortar of the present invention comprises water and a water-absorbing polymer, and has a viscosity of 30 poise to 5,000 poise. If the viscosity of the gel composition for mortar is less than 30 poise, the powder will settle and segregate, and if the viscosity exceeds 5,000 poise, it will become too hard. This is because mixing is impossible and it is difficult to produce plastering materials.

  The content of the water-absorbing polymer in the gel composition for mortar of the present invention is preferably 0.001 to 0.3 when the weight of water to be added is 1. When the water-absorbing polymer content is less than 0.001 when the weight of water to be added is 1, the gel-like composition is too soft or the pore water contained between the gel particles is too much. This is because when the mixture is mixed with an inorganic binding material, mako between particles is generated. On the contrary, if it exceeds 0.3, the gel composition becomes too hard and mixing occurs. Because it becomes impossible.

  The gel composition for mortar of the present invention has a high thixotropy and is close to a solid and normally does not leak water, water vapor, etc., but is mixed with a mortar material containing an inorganic binder. As a result, the metal salt contained in the mortar-based material acts on the gel-like composition, the gel shrinks, and the water necessary to become an appropriate hardness is released, and the particles do not become mako. It is possible to obtain a mortar having good iron slip and very good performance after construction.

  In the present invention, the water-insoluble anionic water-absorbing polymer is preferably a carboxylate-based water-absorbing polymer containing a carboxylate in the molecule, and starch acrylate graft-crosslinking exemplified in the above (1) and (3). More preferred are polymers, cross-linked polyacrylates, cross-linked acrylate-acrylamide copolymers, cross-linked acrylate-acrylate copolymers and cross-linked carboxylic acid-modified polyvinyl alcohols.

  When the water-insoluble anionic water-absorbing polymer is in the form of a neutralized salt, the type of salt and the degree of neutralization with respect to acid groups are not particularly limited. In addition, as for the kind of salt, an alkali metal salt is preferable and a sodium salt and potassium salt are more preferable. 50-90 mol% is preferable and the neutralization degree with respect to an acid group has more preferable 60-80 mol%.

  In the case of the water-insoluble anionic water-absorbing polymer exemplified in the above (1) and (4), the use weight of the crosslinking agent is preferably 0.001% to 5 with respect to the total mass of the monomer and the crosslinking agent. %, More preferably 0.05% to 2%, particularly preferably 0.1% to 1%. When the amount of the cross-linking agent is less than 0.001% with respect to the total mass of the monomer and the cross-linking agent, the water absorption / water retention ability, which is an important function of the water-insoluble anionic water-absorbing polymer, becomes small, and the gel after water absorption This is because it is easy to contain a lot of water-soluble components, the amount of the remaining monomer is increased, and further, the drying property of the hydrogel polymer after polymerization is lowered, so that the productivity is not efficient. If it exceeds 5%, the crosslinking becomes too strong, the water absorption / retention ability is lowered, and the absorption rate is also slowed.

  The polymerization method for obtaining a water-insoluble anionic water-absorbing polymer that can be used in the present invention is not particularly limited, and examples thereof include an aqueous solution polymerization method, a reverse phase suspension polymerization method, a spray polymerization method, a photoinitiated polymerization method, and radiation. Although a polymerization method etc. can be illustrated, the method of carrying out aqueous solution polymerization using a radical polymerization initiator is preferable. The type and amount of radical polymerization initiator used in aqueous solution polymerization using a radical polymerization initiator and the radical polymerization conditions are not particularly limited, and a conventional method can be employed. Note that various additives, chain transfer agents (for example, thiol compounds) and the like may be added to these polymerization systems as necessary.

  The water-insoluble anionic water-absorbing polymer that can be used in the present invention is the vicinity of the surface of the absorbent particles obtained by drying the hydrogel polymer obtained by polymerization, pulverizing, and further adjusting the particle size as necessary. Also included is a surface-crosslinked anionic water-absorbing polymer obtained by surface-crosslinking with a crosslinking agent having at least two functional groups capable of reacting with acid groups and / or bases.

  Such a surface cross-linked water-insoluble anionic water-absorbing polymer is excellent in absorption performance and absorption rate under normal pressure as well as under pressure, and has high gel strength, so that it can be used in the present invention. This is suitable as an anionic water-absorbing polymer.

  As a crosslinking agent used for surface crosslinking, a known crosslinking agent that has been conventionally used can be applied. Specifically, for example, a polyglycidyl ether compound having 2 to 10 epoxy groups in one molecule, a divalent to 20-valent polyol compound, a divalent to 20-valent polyamine compound, a molecular weight of 200 to 500,000 Examples include polyamine resins, alkylene carbonates, aziridine compounds, oxazoline compounds, and polyimine compounds. The polyglycidyl ether compound having 2 to 10 epoxy groups in one molecule is, for example, ethylene glycol diglycidyl ether, glycerin-1,3-diglycidyl ether, glycerin triglycidyl ether, polymerization Polyethylene glycol diglycidyl ether having a degree of polymerization of 2 to 100, polyglycerol polyglycidyl ether having a degree of polymerization of 2 to 100, and the like. Divalent to 20-valent polyol compounds include glycerin, ethylene glycol, polyethylene having a polymerization degree of 2 to 100 For example, ethylenediamine, diethylenetriamine and the like are included in the divalent to 20valent polyamine compounds, and polyamine resins having a molecular weight of 200 to 500,000 include polyamide polyamine epichlorovidin resin, poly It includes such Minh epi black ruby Dorin resin, the alkylene carbonate, for example, include ethylene carbonate. Of these, polyglycidyl ether compounds, polyamine resins, and aziridine compounds are preferable because surface crosslinking can be performed at a relatively low temperature.

  The addition amount of the crosslinking agent in the surface crosslinking may be appropriately changed depending on the kind of the crosslinking agent, the crosslinking condition, the target performance, etc., and is not particularly limited, but is 0.001% by weight based on the anionic water-absorbing polymer. It is preferable to add ~ 3% by weight. When the addition amount of the crosslinking agent is less than 0.001% by weight, there is no great difference in performance from the water-absorbing polymer that does not perform surface crosslinking, whereas when it exceeds 3% by weight, This is because the absorption performance tends to decrease, which is not preferable. The crosslinking agent is more preferably added in an amount of 0.01% to 2% by weight, particularly preferably 0.05% to 1% by weight, based on the water-insoluble anionic water-absorbing polymer.

  The surface cross-linked water-insoluble anionic water-absorbing polymers exemplified above may be used singly or in combination of two or more.

  The shape of the water-insoluble anionic water-absorbing polymer that can be used in the present invention is not particularly limited, and examples thereof include granular, cocoon granular, granulated, flake-shaped, lump-shaped, pearl-shaped, etc. It may have an irregular shape.

  Further, drying and pulverization are as follows. In the case of aqueous solution polymerization, for example, the polymer gel is subdivided or noodled to some extent with a meat chopper or cutter type crusher, and after neutralizing the hydrogel by adding an alkali metal salt hydroxide as necessary. It is performed by a method such as air drying or air drying. Among these, air-permeable drying is preferable because efficient drying can be performed in a short time. On the other hand, in the case of reverse phase suspension polymerization, the method for drying the hydrous gel comprises solid-liquid separation of the polymerized hydrous gel and the organic solvent by a method such as decantation, followed by drying under reduced pressure (degree of vacuum; about 100 to 50,000 Pa). In general, the aeration drying is performed. Examples of other drying methods for the water-containing gel in aqueous solution polymerization include a contact drying method in which the water-containing gel is compressed and stretched on a drum dryer described in Japanese Patent Publication No. 8-28216. Therefore, it is necessary to prepare a thin film of hydrogel on the drum or the like for drying. The drying temperature varies depending on the dryer used, the drying time, and the like, but is preferably 50 to 150 ° C, more preferably 80 to 130 ° C. The drying time varies depending on the model of the dryer to be used, the drying temperature, and the like, but is preferably 5 to 300 minutes, and more preferably 5 to 120 minutes. The dried product of the crosslinked polymer thus obtained is pulverized and powdered as necessary. The pulverization method may be a normal method, and can be performed by, for example, an impact pulverizer (pin mill, cutter mill, skiller mill, ACM pulverizer, etc.) or air pulverization (jet pulverizer, etc.). If necessary, the dried powder can be collected by using a sieve (vibrating sieve, centrifugal sieve, etc.) equipped with a desired screen if necessary.

  The average particle size of the water-insoluble anionic water-absorbing polymer that can be used in the present invention is preferably 10 to 1,000 μm. If the average particle size of the polymer is less than 10 μm, when the polymer forms a water-absorbing gel, the dispersibility in water deteriorates, so that it tends to form a macho shape. Conversely, if the polymer exceeds 1,000 μm This is because the water absorption time becomes longer, which is not preferable. The average particle size of the polymer is more preferably 50 to 800 μm, particularly preferably 100 to 700 μm.

  The average particle size of the water-insoluble anionic water-absorbing polymer can be adjusted by pulverization and sieving, and in the case of reverse phase suspension polymerization, it can also be controlled by the polymerization conditions. The average particle size referred to here means the mass average particle size, and the particle size distribution of the crosslinked polymer is plotted on logarithmic probability paper with the horizontal axis representing the particle size and the vertical axis representing the content based on the mass. It is measured by a method for determining the particle diameter at 50%.

  The water-insoluble anionic water-absorbing polymer that can be used in the present invention preferably has a water absorption weight of 20 g to 1,200 g per 1 g of the polymer. This is because if the water absorption weight of pure water is less than 20 g per 1 g of the polymer, sufficient water retention capacity may not be obtained after water absorption. Conversely, if it exceeds 1,200 g, the gel after water absorption becomes soft. This is because if the bag is perforated, the gel may flow out. In addition, as for the water absorption weight of pure water here, it is more preferable that it is 50-1,000g per 1g of this polymer.

  The water-insoluble anionic water-absorbing polymer has an absorption weight of physiological saline of 0.5 g to 150 g per 1 g of the polymer, and the absorption weight of physiological saline is not more than 0.2 times the absorption weight of pure water. More preferably. In the polymer having such physical properties, when the water-absorbing gel and the inorganic binding material are mixed, the water-containing gel discharges water with the metal salt contained in the inorganic binding material to obtain a mortar having a more appropriate viscosity. Because it can. It is particularly preferable that the absorption weight of physiological saline is 0.1 g to 100 g per 1 g of the polymer.

  Examples of water-insoluble nonionic water-absorbing polymers include (meth) acrylamide cross-linked products, vinyl alcohol polymer cross-linked products, ethylene oxide polymer cross-linked products, polyhydroxyalkyl (2 to 5 carbon atoms) (meth) acrylate cross-linked polymers. Polyethylene glycol (molecular weight of PEG moiety: 200 to 4,000) (meth) acrylate polymer crosslinked product, polymethoxy PEG (PEG molecular weight: 200 to 4,000) (meth) acrylate crosslinked polymer, starch crosslinked product, hydroxy An ethyl cellulose crosslinked body etc. can be illustrated.
