What is the function of adding carbon black in rubber tires?

- Sep 11, 2019-

Carbon black is mainly used in tires of rubber industry.The carbon black used in the tire industry accounts for more than 80% of the carbon black needed in the rubber industry.Rubber products other than tires of various motor vehicles (including motorcycles) are generally referred to as "rubber products".Rubber products consume about 20% of rubber carbon black every year.


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 various products, the rubber formulation personnel comprehensively consider the selection of reasonable formula, various compounding agents and adding process conditions from the use of rubber, vulcanization system, reinforcing and filling system, softening system, aging system and 3252 art system to meet the requirements of product performance.


Carbon black is an important reinforcing filler in the reinforcing filling system, which has an important influence on the physical and mechanical properties and processing technology of rubber, but the influence on the properties of heat resistance, oil resistance, corrosion resistance medium and other properties of rubber is far less significant than that of rubber, vulcanization system and protection system.Because of this reason, the general rubber formula staff on a specific performance indicators of carbon black than carbon black technical staff attention, often only pay attention to select a certain type of carbon black, and do not investigate the use of carbon black specific indicators, or through different varieties of carbon black and use, carbon black and inorganic filler and meet the use requirements of products.So it is difficult to quantify the impact of specific physical and chemical indicators of carbon black.
