Abstract

The invention relates to a method for preparing rubber, and provides a method for preparing low-heat-generation fatigue-resistant vulcanized rubber. In a rubber formulation, starch or modified starch is adopted to be combined with a coupling agent into a low-heat-generation fatigue-resistant additive; other additives such as carbon black, stearic acid, zinc oxide, accelerator, sulfur, anti-aging agent and process oil are not changed; and a main rubber material selected is polydiolefin rubber, such as natural rubber, styrene-butadiene rubber, 3-polybutadiene rubber, butadiene acrylonitrile rubber or a mixture thereof. Through common rubber processing technology and equipment, the starch or the modified starch is taken as a functional rubber additive to prepare the rubber with low heat generation and long fatigue lifespan, and the heat generation and bending-resistant lifespan of the vulcanized rubber are obviously improved. The rubber of the species can be used in tires and other rubber products.

Description

technical field [0001] The invention relates to a method for preparing rubber, in particular to a method for preparing vulcanized rubber with low heat generation and fatigue resistance. Background technique [0002] In the rubber industry, the main reinforcing agent for traditional rubber is mainly carbon black filler. However, because carbon black will cause serious damage to the surrounding environment during the production process, and at the same time, the vulcanized rubber obtained by using carbon black as a rubber reinforcing agent has problems such as high heat generation and low elasticity, which is not conducive to improving the service life of rubber products. , For example, automobile tires at high speeds are often scrapped due to heat generation and explosion. Therefore, people have been looking for a functional additive to replace part of carbon black to prepare vulcanized rubber with low heat generation and high fatigue life for tire treads. , sidewalls and ot...
