Color mix binder for plant mix color packaging {Plant mix type color binder for color paving}

The present invention relates to a color mix binder for plant mix color paving for the production of a mixture of color asphalt pavement, which compensates for the disadvantages of conventional color asphalt and color concrete and exhibits better physical properties of color pavement. Color concrete and general color asphalt, which are used in sports facilities such as roads and sports fields, have various disadvantages, and thus have many difficulties in popularizing color pavement. Take the disadvantages as an example

(1) Disadvantages of color concrete include ① prolonged construction period due to curing time of concrete and epoxy coating and ② complexity of process due to expansion joint construction ③ increase of labor cost due to prolongation of construction period and complexity of construction process ④ weak Cracking due to impact resistance ⑤ Discoloration of color due to peculiar whitening of concrete ⑥ Difficulty in maintenance after construction, etc. (2) Disadvantages of conventional color asphalt are as follows ① Using heated liquid binder As it is a product, it is difficult to produce a small amount of unit. ② Since the binder is transparent or translucent, a separate dedicated storage tank is needed. ③ The physical properties of the binder are altered by repeated heating and cooling, which are heated when the binder is used and cooled during long-term storage. Quality control is difficult, and ④ It is possible to Problems such as a large amount of time is required to raise the bar The present invention relates to a colored binder for plant mix color packaging that can solve the above problems.

The present invention improves the physical properties of the binder in order to solve the problems listed above at the same time, the binder is produced as a solid particle, to solve all problems and at the same time to produce a mixture as it is produced without improving the general ascon plant The primary objective is to lay the foundation for popularization of color packaging by minimizing the additional costs incurred. The present invention can be solved naturally because the construction of the present invention is the same as the construction of the present invention as the construction of the present invention is the same as the general asphalt concrete construction, the problem of the prolonged construction, the complexity of the process, thereby increasing labor costs It is sufficiently improved by ductility and strength. In addition, the problem of whitening can be solved by the coloring pigment of the binder. And since it is a product that uses heated liquid binder which is a disadvantage of the existing color asphalt, it is difficult to produce a small amount of the unit because the colored binder for plant mix color paving is used in the solid phase at room temperature, so it is possible to solve the minimum unit production at any time. In addition, the need for a dedicated storage tank of the color mix binder for the plant mix type packaging according to the present invention is used in the solid phase at room temperature, so that a separate dedicated tank is not necessary, thereby reducing the production cost of colored asphalt. In addition, the physical properties of the binder is difficult to control the quality is also a disadvantage that the color mix binder for the plant mix color packaging according to the present invention can always maintain a constant quality because it does not require any processing such as heating when storing. In addition, the problem that takes a long time to make a liquid to be used by heating the cooled binder to produce once, the present invention can be solved by using at room temperature. Therefore, in order to achieve the above object, various colors can be expressed as it is by using a colored plant-mixed color packing binder which is solid at room temperature, not a general heating liquid transparent binder, and ensures excellent color stability and workability. It has excellent durability due to its excellent aggregate grasping ability and adhesion, so it can be used for heavy vehicle transportation (eg bus lanes) It is an object of the present invention to provide a colored binder for plant mix color pavement that can be applied to roads.

The present invention according to the first aspect for achieving the above object is 10 to 30% by weight of process oil and 20 to 60% by weight of petroleum resin or thermoplastic resin, thermoplastic elastomer (hereinafter referred to as 'TPE') or rubber 15 to 30 weight% is disperse | distributed uniformly at the temperature of 160-200 degreeC, 0.1-0.5 weight% of heat-resistant antioxidants and 0.1-0.5 weight% of ultraviolet stabilizers are further added to it, and the compatibility of a polymer and resin is improved here. After adding 0.1 to 0.5% of a special additive to be added, the inorganic or organic pigment of a desired color is added to the uniformly mixed binder in a ratio of 20: 1 to 10: 1 by weight of the binder: pigment, and sufficiently dispersed to a uniform phase. The manufacturing method of the color mix binder for plant mix type which consists of shape | molding it to the solid particle shape of 1 cm or less in diameter and 2 cm or less in length was implemented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments according to the present invention will be described in detail. It should be noted that in the following description, only parts necessary for understanding the present invention will be described, and descriptions of other parts will be omitted so as not to distract from the gist of the present invention. .

First of all, if you look at the concept of the present invention implemented above, compared to the physical properties of the existing general color asphalt and color concrete, it is possible to secure more than the same physical properties, easier quality control, can be produced in all ascon equipment, small quantity production, It does not need a separate storage facility, it is to present a method for producing a colored binder for plant mix color packaging that can be used as it is at room temperature. That is, 10 to 30% by weight of process oil, 20 to 60% by weight of petroleum resin or thermoplastic resin, 15 to 30% by weight of TPE or rubber are uniformly dispersed at a temperature of 160 to 200 ° C, and 0.1 to 0.5% by weight of heat resistant antioxidant. %, 0.1-0.5% by weight of UV stabilizer is added, and 0.1-0.5% of a special additive which improves the compatibility between polymer and resin is added thereto, followed by inorganic or organic pigment of desired color in a uniformly mixed binder. The binder: pigment weight ratio was added in a ratio of 20: 1 to 10: 1 and sufficiently dispersed so as to be a uniform phase, and then molded into a solid particle having a diameter of 1 cm or less and a length of 2 cm or less, thereby producing a colored binder for plant mix color packaging. Suggest a method.

Hereinafter, the present invention will be described in more detail.

Color mixing binder for plant mix color packaging according to the present invention is 10 to 30% by weight of process oil, 20 to 60% by weight of petroleum resin or thermoplastic resin, 15 to 30% by weight of TPE or rubber, 0.1 to 0.5% by weight of heat resistant antioxidant, UV It is composed of 0.1 to 0.5% by weight of stabilizer, 0.1 to 0.5% of special additive which improves the compatibility of polymer and resin, and inorganic or organic pigment of binder: pigment weight ratio of 20: 1 to 10: 1.

The role of each component used in the present invention is as follows. The process oil first serves as a hot solvent for homogeneously dispersing the polymeric material, preferably TPE and rubber. However, in the plant mixed color packaging colored binder of the present invention, when the composition is less than 10% by weight, the process oil sufficiently serves as a high temperature solvent for uniformly dispersing TPE and rubber in producing the colored binder for plant mixed color packaging. Undigested TPE and rubber remain undispersed in the colored binder for plant mix color packaging, so it is difficult to secure sufficient physical properties of the color asphalt composition and quality control is also difficult. In addition, in the colored binder for plant mix color packaging of the present invention, the process oil is easy to disperse TPE and rubber in manufacturing the colored binder for plant mix color packaging when the composition exceeds 30% by weight, but for plant mix color packaging It is very difficult to make a colored binder into 1 cm or less in diameter and 5 cm or less in length, and it is difficult to commercialize it.

In addition, the petroleum resin and the thermoplastic resin play a role of improving adhesion between aggregates in the color asphalt composition, securing dispersion fluidity of TPE and rubber, and improving hardness and durability of the binder itself. However, petroleum resins and thermoplastic resins in the color mixing binder for plant mix color packaging of the present invention are difficult to secure the dispersion fluidity of TPE and rubber in the production of color binders for plant mix color packaging when the composition is less than 20% by weight. Since sufficient adhesive strength is not given to the asphalt composition, problems such as aggregate detachment may occur. In addition, the petroleum resin and the thermoplastic resin in the plant-mixed color packaging colored binder of the present invention, when the composition exceeds 60% by weight in the production of the color-mixed binder for the plant mixed color packaging to secure the dispersion fluidity and adhesion of the TPE and rubber It is significant but due to this relatively rigidity there is a problem that does not sufficiently secure the elasticity of the color asphalt.

In addition, the TPE and rubber give low temperature elasticity and high temperature durability to the pavement in the color asphalt composition, thereby providing physical properties corresponding to low temperature cracking and plastic deformation of the roadway. However, in the colored binder for plant mix color paving of the present invention, when TPE and rubber are less than 15% by weight, it is difficult to secure elasticity and durability of the color asphalt composition in plant mix type color paving. It becomes impossible to play a role as a colored binder for color packaging. In addition, in the colored binder for plant mix color pavement of the present invention, the TPE and rubber are difficult to uniformly disperse in manufacturing the colored binder for plant mix color pavement when the composition is more than 30% by weight. There is a problem such as deterioration.

In addition, in the present invention, the heat resistant antioxidant is added in an amount of 0.1 to 0.5% by weight in order to prevent oxidation and deterioration at high temperatures of the TPE and rubber, and the UV stabilizer is ultraviolet aging due to sunlight when the color asphalt composition is paved on the road. In order to prevent the addition of 0.1 to 0.5% by weight is added, the special additive is added to 0.1 to 0.5% by weight in order to improve the compatibility of the polymer and resin, the inorganic or organic pigments are pre-colored in the binder and ascone In order to reduce the process of adding the pigment directly to the production plant, and to evenly disperse the pigment and prevent the loss of the pigment due to the dust collector, it is blended with the binder in a binder: pigment weight ratio of 20: 1 to 10: 1 to mix the plant color. It is used as a means for facilitating the production of a packaging colored binder.
