Rubber roadbed block using waste tire rubber chips which is utilized by recycred rabber chips}

The present invention relates to a rubber ballast block using waste tire rubber chips. In particular, the present invention is installed on a sleeper in which a track is installed to buffer a shock of a track receiving low-frequency vibration generated from a wheel when a subway, a high-speed train, or a high-speed train travels. The first step of mixing the waste tire rubber chip and the accelerator with the dust-proof block to cushion the shock, the second blending step of blending the secondary accelerator to the blended raw material, and the third vulcanization treatment of the blended blended raw material The blending step is carried out by conveyor conveying to low temperature culture treatment, the fourth blending step, the press molding of the rubber ballast block, and the inspection step to install the rubber ballast ballast prepared on the sleeper for dustproof and soundproofing. The present invention relates to a rubber-like ballast block using waste tire rubber chips having excellent effects.

In general, as the number of subways, high-speed trains, and high-speed trains increases due to the increase in the flow population and traffic volume, low-frequency vibrations transmitted from the wheels of trains are transmitted to the foundation ground, which affects various structures around rails, sleepers, and rails. There was a problem that the cracking of the structure, exposure to the risk of accidents and falling passengers feeling.

Conventionally, in order to solve the above problems, it is installed between the sleeper and the rail to reduce noise and vibration only to the dust pad and the dust box in the concrete phase, but the shock absorbing effect is lower than expected, and maintenance and construction are difficult. Have

In addition, the work process that has to go through various work processes such as formwork, ready-mix concrete laying, curing, etc. for placing concrete works is cumbersome, and imported rubber pads or used as general-purpose rubber, which is undesirable in terms of excessive facility cost and resource recycling. Have.

The present invention was devised to solve the above problems, the object of the present invention is to receive the load acting on the rail primarily from the sleeper, and secondly manufactured by recycling waste tires, natural rubber, etc. The block is installed under the sleeper support to provide a rubber ballast block using waste tire rubber chips that can significantly reduce vibration and noise.

In addition, the design of the waste tire, which is rapidly growing as a by-product of the automobile industry, has to be solved in terms of efficient recycling of resources and environmental conservation. It is composed of synthetic rubber of high-quality materials rich in calories, and unlike other wastes, it does not need special collection and sorting process, so it is very valuable as a recycling business. There are only a few treatment facilities in the stage, so one of the ways to increase the actual recycling rate of waste tires is to provide rubber-like ballast blocks using waste tire rubber chips.

In order to achieve the above object, the present invention primarily blends 100 parts by weight of waste tire rubber chips, 3 parts by weight of zinc (ZnO), and 1 part by weight of stearic acid (St / A) to a high-speed rotary mixer. Making a step; Second blending the blended compound by adding 0.5 parts by weight of accelerator M, 0.5 parts by weight of DM, 1 part by weight of CZ, and 0.1 parts by weight of TT; A third compounding step of combining 1.5 parts by weight of yellow crystals and 4 parts by weight of Neospangol to the blended compound; A conveyance transfer step of conveying the blended compound from a blender to a low temperature culture processor; A low temperature culture treatment step of treating the transferred compound in the low temperature culture processor for 24 hours; A fourth blending step of blending 60-90 parts by weight of waste tire rubber chips and 40-10 parts by weight of silica sand (fine aggregate) to the blender for 5 to 8 minutes through the low temperature culture treatment step; Injecting the blended material into a mold mold; Press-molding the injected material to at least 500 t with a high pressure press; The rubber-shaped ballast block using waste tire rubber chips manufactured by the manufacturing method of the step of inspecting the pressure-molded block has a space groove part inside the upper surface to have the same shape for inserting and supporting the sleeper, and vibration damping at the lower side. It is an object of the present invention to provide a rubber ballast block using a waste tire rubber chip, characterized in that the unit is integrally configured.
