Abstract
The invention discloses a formula of rubber material for automobile inner tubes, which comprises 81-109 parts of raw rubber, 25-41 parts of rosin soft styrene-butadiene, 92-115 parts of butyl rubber and 2-7 parts of zinc oxide in parts by weight. , 2-5 parts of calcium stearate, 15-30 parts of semi-reinforcing carbon black, 10-23 parts of high wear-resistant carbon black, 2-7 parts of pine tar, 8-14 parts of mixed gas carbon black, 2-4 parts of anti-aging agent 1-3 parts of paraffin, 4-6 parts of asphalt, 0.5-1.5 parts of accelerator. The invention has extremely reasonable design of mixing ratio, is suitable for the needs of existing production and life, has low cost, high labor productivity, low energy consumption in the processing and manufacturing process, and can achieve high-yield rubber formula.
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...
