Problems solved by technology

Due to the existence of a large number of unsaturated bonds in the SBR macromolecular chain, it is prone to aging under heat or hot oxygen conditions, and its thermal oxygen aging resistance and ozone aging resistance are also poor, and it is more likely to age and fail in electronic products that vibrate and heat. App is restricted

Abstract

The invention discloses an ageing-resistant shock-absorption styrene butadiene rubber material. The ageing-resistant shock-shock-absorption styrene butadiene rubber material is prepared from the following various ingredients in parts by weight: 50-65 parts of butadiene-styrene rubber, 40-50 parts of natural rubber, 15-18 parts of carbon black, 100-120 parts of modified light calcium, 80-90 parts of naphthenic oil 4010, 1-1.5 parts of an anti-ageing agent HS 911, 1-1.5 parts of an anti-ageing agent MB, 6-8 parts of zinc oxide, 1.2-1.5 parts of stearic acid, 1-2 parts of microcrystalline wax, 0.6-0.8 part of sulfur and 5-6 parts of an accelerant.

Description

technical field [0001] The invention relates to the technical field of styrene-butadiene rubber, in particular to an aging-resistant and shock-absorbing styrene-butadiene rubber material. Background technique [0002] With the rapid development of industry, vibration and noise have become serious problems in various fields. It affects product quality, reduces operating accuracy, shortens product life, endangers product safety, pollutes the environment and affects personal health. In order to prevent the noise and vibration produced by automobiles, home appliances and other vehicles and industrial machinery, in addition to reducing or eliminating the vibration of the vibration source, it is more practical to develop and utilize various shock-absorbing products, among which rubber shock-absorbing products are particularly important. made of. The elasticity of rubber has the characteristics of both elasticity and viscosity, also known as viscoelasticity. Its elasticity comes f...
