Abstract

The invention discloses a method for preparing a hard abrasion-resistant automobile tire rubber material. According to the rubber material disclosed by the invention, carbon nano tubes, borax and nano silica powder are mixed and organized, so that the compatibility of the filler and rubber is effectively improved, agglomeration is reduced, the stability intensity and surface hardness of the finished material are improved, the silica powder has an excellent lubricating property, and the abrasion resistance of the finished material is improved.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of a hard wear-resistant automobile tire rubber material. Background technique [0002] Because natural rubber has the above-mentioned series of physical and chemical properties, especially its excellent resilience, insulation, water resistance and plasticity, and, after proper treatment, it also has oil resistance, acid resistance, alkali resistance, heat resistance, cold resistance, and heat resistance. Pressure, wear resistance and other valuable properties, so it has a wide range of uses. For example, rain boots, warm water bags, and elastic bands used in daily life; surgeon gloves, blood vessels, and condoms used in the medical and health industry; conveyor belts, conveyor belts, acid-resistant and alkali-resistant gloves used in industry; drainage and irrigation hoses used in agriculture , ammonia water bags; sounding balloons for meteorological me...
