Abstract

The invention discloses a formula of mixing type polyurethane rubber, which comprises 87-104 parts of raw material mixing type polyurethane rubber, 12-29 parts of coumarone resin, 6-9 parts of accelerator, and anti-aging agent, calculated according to parts by weight 1‑3 parts, 2‑5 parts of sulfur, 4‑6 parts of high wear-resistant carbon black, 2.5‑4 parts of stearic acid, 6‑9 parts of sodium stearate, 11‑19 parts of sulfur, 2‑6 parts of pine tar , the present invention has an extremely reasonable mix design, is suitable for the needs of existing production and life, has low cost, high labor productivity, low energy consumption in the 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 of mixing type polyurethane 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 mix-type polyurethane rubber has an unreasonable design of mixing ratio, cannot meet the needs of existing production and life, has high cost, low labor productivity, high energy consumption in the process of processing and manufacturing, and cannot achieve high yield.
