What effect does carbon black matte powder have in rubber?
The main function of carbon black in rubber is to strengthen, improve wear resistance and reduce cost.Carbon black matting powder is mainly used in rubber industry tires.The carbon black used by the tire industry accounts for more than 80% of the total carbon black required by the rubber industry.Generally all kinds of motor vehicles (including motorcycles) other rubber products other than tires collectively referred to as "rubber products."The carbon black consumed by rubber products accounts for about 20% of the carbon black used in rubber.Carbon black is mainly used as reinforcing agent and filler of rubber. Its consumption is about half of the consumption of rubber. Carbon black of rubber accounts for 94% of the total amount of carbon black.In addition, it is also used as a colorant for ink, coatings and plastics, as well as uv screening agent for plastics.It is also an important additive in many other products such as electrodes, dry batteries, resistors, explosives, cosmetics and polishing creams.Carbon black is mainly used for rubber products. The finer the particle size of carbon black, the better its reinforcing performance.The higher the degree of structure of carbon black matting powder, the higher the stress and modulus of constant elongation.The reinforcing variety of fine particle size is mainly used for tire tread, which endows the tire with excellent wear resistance.Other parts of the tire, such as the tire side, curtain layer, belt buffer layer and lining layer, the rubber material resistance to flexure cracking, ozone oxidation resistance, good resilience and low heat generation performance, generally choose the coarse particle size of semi-reinforced type (specific surface area less than 40m2/g) furnace black.
Carbon black is an important reinforcing filler in the reinforcing and filling system, which has an important impact on the physical and mechanical properties and processing technology of rubber rubber, but the influence on the properties of heat resistance, oil resistance and corrosion resistance of rubber rubber, vulcanization system and protection system is far less large and direct.Due to this reason, the general rubber formula personnel pay less attention to the specific performance index of a certain kind of carbon black than the carbon black technical personnel, often only pay attention to the selection of a certain type of carbon black, but do not investigate the specific index of using carbon black, or through the use of different varieties of carbon black, carbon black and inorganic filler and meet the use requirements of products.Therefore, it is difficult to quantify the influence of concrete physicochemical indexes of carbon black matting powder.
There are many different kinds of rubber products and conditions of use and performance requirements vary, according to the main functions, tape, rubber hose, rubber sheet, rubber damping products, rubber products, rubber roller, conductive or anti-static rubber products, hard rubber and rubber shoes and so on several categories of products, and each type of rubber products according to the purposes, conditions of use and divided into several varieties.In order to meet the performance and use requirements of different products, the rubber formula personnel from the use of rubber, vulcanization system, reinforcing filling system, softening system, aging prevention system and add 3252 art system, comprehensive consideration to choose a reasonable formula, various coordination agents and adding process conditions, to meet the requirements of product performance.
