Abstract

The invention discloses a formula of rubber for an automobile inner tube. The formula comprises the following components in parts by weight: 81-109 parts of raw material rubber, 25-41 parts of rosin soft butylbenzene, 92-115 parts of butyl rubber, 2-7 parts of zinc oxide, 2-5 parts of calcium stearate, 15-30 parts of semi-reinforcing carbon black, 10-23 parts of high wear-proof carbon black, 2-7 parts of pine tar, 8-14 parts of mixed gas carbon black, 2-4 parts of an anti-aging agent, 1-3 parts of paraffin, 4-6 parts of asphalt and 0.5-1.5 parts of an accelerant. The formula of rubber is veryreasonable in mixture ratio design, suitable for existing production and living requirements, low in cost, high in labor productivity, low in energy consumption in processing and manufacturing procedures, and capable of achieving high yield.

Description

technical field [0001] The invention relates to the field of rubber preparation, in particular to a formula for automobile inner tire rubber. Background technique [0002] Early rubber was latex taken from plants such as rubber trees and rubber grasses, which were processed into materials with elasticity, insulation, impermeability to water and air. High elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life. The existing automobile rubber tread mix design is unreasonable, cannot be applied to the needs of existing production and life, has high cost, low labor productivity, high energy consumption in the process of manufacturing, and cannot achieve high yield. Contents of the invention [0003] The present in...
