Looking at the preferred embodiment of the present invention together with the accompanying drawings as follows, when it is determined that the detailed description of the known art or configuration related to the present invention may unnecessarily obscure the subject matter of the present invention The description will be omitted, and the terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to intentions or customs of users or operators, and the definitions describe the manufacturing method of the laminated color rubber chip according to the present invention. It should be made based on the contents throughout the specification.

Hereinafter, a method of manufacturing a laminated color rubber chip according to a preferred embodiment of the present invention will be described.

2 is a flowchart illustrating a process of manufacturing a laminated color rubber chip according to an embodiment of the present invention.

As shown in Fig. 2, the manufacturing method of the laminated color rubber chip is as follows.

The first step is blending and branding, 3 to 5 parts by weight of zinc oxide, 1 to 3 parts by weight of antioxidant, 100 to 300 parts by weight of filler, 2 to 4 parts by weight of sulfur, in 100 parts by weight of synthetic rubber 4 to 6 parts by weight of a vulcanizing agent and a vulcanizing agent, 2 to 4 parts by weight of a plasticizer and a softener, and 1 to 10 parts by weight of color pigments, and then branding the synthetic rubber with any one of a kneader mixer, a bandari mixer, and a mixing roller. To make.

Here, the raw rubber is pressed by a kneader mixer, a half-barrier mixer, mixing roller 40, and the molecular weight is adjusted to increase plasticity and graduality, and is a rubber formed by mixing a filler galvanizing vulcanization accelerator. In addition, the synthetic rubber (Synthetic rubber) is styrene butadiene rubber (SBR: styrene butadiene rubber), nitrile butadiene rubber (NBR: nitrile-butadiene rubber), ethylene propylene rubber (EPDM: Ethylene Propylene Terpolymers), polybutadiene rubber (BR : Polybutadiene rubber (CR) or chloroprene rubber (CR: Chloroplene rubber) is one or two kinds of mixed branding. Chloroplene rubber (CR) is also referred to as neoprene rubber.

The Kneader mixer is a mixing machine similar to a short-barrier mixer. Like the rubber two-stage mixer, the machine is small and it depends on the specifications. The screw type and the cooling device are used up to 150 ℃. The rubber mixing is completed by mixing at high temperature and putting down the accelerator in the low temperature two-stage roller machine.

In addition, the Bnbary mixer is a mixing machine that mixes rubber dough compound, polyethylene, vinyl, EVA, resin, etc., by processing up to 180 ℃, the accelerator is mixed and processed in the Barbary mixer. Put the accelerator back on the 2nd roller and lower the work by adding accelerator at low temperature. The roller is screw type, and the cooling device and the thermometer are attached. Unlike the two-stage roller mixer, the roller is opened and opened at high temperature and mixed, so that there is no branch in the factory and the production process is large.

In addition, the rubber mixer two-stage mixing roller is a mixing down processing machine that passes through the primary gate in rubber production. The rotating ratio is 1: 125, and the rubber is rolled down and the compound is processed according to the slow rotation and the rear roll. It is an indispensable primary rubber processing machine in the rubber industry. For rubber down machining, 60 ° C is most suitable for the temperature of the roller.

The second step is a sheet manufacturing step, in which the branded raw rubber, which is formed in each color, is made into a sheet having a sheet shape of 1 to 10 mm using a roller 40 or a calendar.

The third step is to design and manufacture in a multi-layered structure, each of the sheets are laminated in 2 to 15 kinds of colors according to the color sorting order by pressing any one of the mixing roll, calender, extruder, hydraulic press (50) It is made of a multilayer sheet 30. Here, the hydraulic press is a vulcanization press because it applies pressure while applying a temperature. The pressure applied to the skin surface of the unvulcanized chip in the hydraulic press 50 is 50 to 100 kg / ㎡, in the case of vulcanized chip is 100 to 200 kg / ㎡, in the case of vulcanized chip using a vulcanized press or continuous vulcanizer 3 to 10 minutes of vulcanization at 100 to 200 ° C.

The vulcanization (vulcanization) is a hardening operation by sulfur compounding of raw rubber, in which chain rubber molecules are entangled with each other to give rubber elasticity, thereby forming a three-dimensional network structure so that plastic deformation does not occur. In addition, the vulcanized rubber has a higher tensile strength, resists swelling and abrasion, and has a wider temperature range for maintaining elasticity. The simplest form of vulcanization is to heat the rubber with sulfur and accelerators.

The press vulcanization is achieved by supplying heat and pressure into the press. Press vulcanization consists of two or more plates that are pressed and detached by hydraulic pressure, and the hot plate is usually heated by steam or electricity. Rubber products are vulcanized in various types of molds between press plates. In its simplest form, the mold consists of two metal plates with a cavity that matches the appearance of the final product. Molded rubber products are removed from the mold and cooled to room temperature to shrink to a smaller size than the cavity. This mold shrinkage is due to the thermal contraction rate of the rubber, which is much larger than the metal shrinkage rate. The coefficient of thermal expansion of rubber is about 10 times that of metal. The coefficient of thermal expansion of the rubber compound is deeply related to the type and amount of fillers put into the raw material rubber, but the number of thermal expansion decreases as the amount of the filler is increased. In order to produce products with accurate dimensions, molds are made larger than actual products. Since most rubber compounds cause similar mold shrinkage, rubber products made from the same mold have almost similar dimensions.

In the continuous vulcanization method, the molding and vulcanization of the rubber compound are performed continuously in one process. Continuous vulcanization is typically used to produce extruded products, insulated wires, conveyor belts, flooring, and the like. There are several methods of continuous vulcanization, but the principle is largely the same. That is, the unvulcanized product moves along the vulcanized medium. Vulcanizing media include liquids, heated air, steam, microwaves, infrared rays, radiation, and the like. Continuous vulcanization with a liquid bath is called the Liquid Curing Method (LCM), where the extrudate passes through a liquid bath at a suitable temperature as soon as it exits the extruder. The temperature of the liquid bath is maintained at about 200 to 300 ℃, the heating medium is a salt mixture, polyglycol, silicone oil, metal alloy and the like. When vulcanizing a thin product, it is possible to pass it through a hot air tunnel or use a fluidized bed of small glass grains suspended in hot fluid air. The latter heat transfer effect is much greater. Flat products such as conveyor belts and flooring are continuously vulcanized in a rotaque method, which is pressed against a large heating drum that slowly rotates the material with a wide sheet of steel.

The fourth step is a pulverization step using a pulverizer, wherein the multilayer sheet is pulverized to a size of 1 mm to 15 mm to produce various patterns of the product by using a pulverizer. Here, the outer shape of the multi-layered multi-colored luminous rubber chip 10, which is pulverized to produce various patterns, is in the shape of tetrahedron or polyhedron, and the laminated color is in harmony with 2 to 15 kinds of colors.
