Abstract

The invention relates to a rubber formula for rubber filled with carbon black. The components of the formula and the mass parts of each component are as follows: 10 parts of the rubber, 11-25 parts of the carbon black, 0.1-7.5 parts of organosilicon and 0.1-5 parts of a compounding ingredient. The rubber formula can reduce cost for rubber products, improve usage performance of the rubber products and make materials dispersed uniformly. The rubber products have relatively strong wear resistance and relatively long service life, and have wide market prospects.

Description

technical field [0001] The invention relates to a formula for rubber production, in particular to a formula for filling carbon black rubber compound. Background technique [0002] Carbon black refers to fine particles formed after incomplete combustion of coal, petroleum, biomass fuel, etc. After entering the atmosphere, carbon black can absorb sunlight and reduce the solar radiation reaching the ground. It is a black powdery substance formed by incomplete gas phase combustion or pyrolysis of hydrocarbons under strictly controlled process conditions. Its composition is mainly elemental carbon, and contains a small amount of oxygen, hydrogen and sulfur. The carbon black particles are approximately spherical, and the particle size is between 10 and 500 μm. Many particles often fuse or coalesce into three-dimensional bonded dendritic or fibrous aggregates. In rubber processing, it is added into rubber by mixing as reinforcing agent (see reinforcing material) and filler. Ca...
