Description

Color rubber mat production equipment for interior materials {PLANT FOR PRODUCING COLOR RUBBER MAT AS INTERIOR MATERIAL}

The present invention relates to a production apparatus for color rubber mats manufactured using waste tire rubber powder.

Elastic flooring manufactured using rubber powder is effective in preventing joint fatigue when used, can remove noise and vibration, and can prevent slipping, so it can be used for corridors, buses, high-speed trains, subways of sports facilities, hospitals, schools and concert halls. It is usefully used as a flooring material.

Along with the increase in the production of automobiles, the amount of waste tires is currently about 257,000 tons per year, the treatment problem and the development of recycling technology is a very important concern. Currently, these waste tires are incinerated in cement plants and used as energy sources, but these treatment methods cause secondary pollution and cause serious environmental pollution. Therefore, the method of incineration of waste tires is gradually decaying in foreign countries, and efforts to develop technologies for recycling them environmentally friendly are gradually increasing.

Tire rubber has elasticity in its characteristics, and because of its strong adhesive strength and good abrasion resistance, it is very useful in the treatment of waste tires when manufacturing rubber mat using tire powder, and it is possible to achieve the advantageous effects as described above. At present, it is a major concern of research and development.

In particular, elastic flooring using rubber powder suitable for indoor interior materials is widely used in developed countries. However, in Korea, only rubber blocks for exterior materials used for sidewalk blocks or outdoor sports facilities are mainly produced. The situation is imported and used. Accordingly, there is a need to produce rubber mats that can be used for indoor flooring in Korea.

Indoor flooring materials commonly used in Korea are generally inconvenient to use due to lack of elasticity, severe noise and vibration during walking, and problems with stability. In addition, in the case of elastic flooring material produced overseas, the polymer produced from ethylene propylene diene monomer (EPDM) is mixed with waste tire powder as a color medium. It is produced through batch operation to cut individually to 1-2m ² and thickness 10-200mm using. Such a manufacturing method has disadvantages of low productivity due to high price of color media and poor productivity because it is not continuous automatic operation.
