Application of new kaolin in rubber sole rubber

The results show that the content of bound water in the calcined kaolin decreases with the calcined kaolin, the content of silica and alumina increases, the activity increases, the structure changes, the particle size is small and uniform, and the calcined kaolin Compared with the NR compound, the vulcanization characteristics of the calcined kaolin-filled NR were basically the same ultrafine mill. The hardness of the A-type A was constant and the tensile strength was improved. The physical properties of the composites were all required to meet the industry standard of sports shoes. The
Recently, the application of ceramics, rubber, plastic, artificial leather, cement, refractory materials, chemical industry and agriculture has not been widely used.With the further improvement of the beneficiation process of high sandy soil, the application range of kaolin is becoming more and more extensive. , Can proceed from the actual situation, based on coal-bearing strata in the high soil resources and market demand. Kaolin is a kind of non-metallic mineral which is commonly found in nature. In the past, it is generally used to produce ceramics, refractory materials and a small amount of plastic and rubber. As the national economy develops in various fields, people pay more and more attention to high So that it can not only acquire new materials with special properties, but also improve the economic efficiency.
One of the methods of deep processing of kaolin is to further heat, roast and dehydrate the kaolin, which has been washed and worked hard to make it into metakaolin, and used as a filler for the plastic cable section to improve the insulation of the cable sheath performance. Commonly used footwear rubber filler mainly organic filler and inorganic filler two, the former, including recycled rubber and recycled materials, which include white carbon black, calcium carbonate, titanium dioxide, magnesium carbonate, magnesium oxide, carbon black and Zinc powder and so on. Kaolin is a new type of rubber product filler developed in recent years.
But all applications in kaolin must be processed into fine powder before they can be added to other materials and fully integrated. The mill products are: Raymond Mill, medium-speed ultra-fine milling machine, micro-powder mill, powder mill, etc., for kaolin, barite, calcite, potassium feldspar, talc, marble, limestone , Ceramic and other Mohs hardness of not more than 7, humidity below 6% of non-flammable and explosive mining, chemical, building materials, metallurgical and other industries more than 280 kinds of materials, milling processing, so the kaolin fine powder processing is easy.
