Problems solved by technology

However, the chemical composition of natural rubber is mainly cis-1,4-polyisoprene, which contains a large number of unsaturated double bonds, which is easy to carry out autocatalytic reaction with oxygen in the air, causing molecular chain scission or excessive crosslinking, Viscosity and cracks occur in rubber, which greatly limits its application in practice

Abstract

The invention discloses an anti-aging modified natural rubber composite material. The anti-aging modified natural rubber composite material is prepared from natural rubber, butadiene rubber, butadiene styrene rubber, butadiene-acrylonitrile rubber, epoxidized natural rubber, nano-zinc oxide, stearic acid, sulfur, dicumyl peroxide, triallyl trimellitate, p-tert-butyl-phenolic resin, nano calcium carbonate, precipitated silica, carbon black purple, nano-microcrystalline cellulose, nano-silicon dioxide, an anti-aging agent, potassium iso-propyl xanthate, dibenzylamine, tetrahydrofurfurylamine, isopropyl trioleoyl titanate, vinyltris(beta-methoxyethoxy)silane, diethylene glycol distearate and polyethyl dialcohol adipate. The anti-aging modified natural rubber composite material is high in strength, good in heat resistance and aging resistance and capable of meeting the usage requirements of multiple fields of cables, rubber pipes and the like.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an aging-resistant modified natural rubber composite material. Background technique [0002] Natural rubber has high elasticity at room temperature, slightly plastic, very good mechanical strength, low hysteresis loss, low heat generation during multiple deformations, so its flex resistance is also very good, and its shock resistance and drop The noise effect is obvious. At present, it has been widely used in cables, pipes and other fields. However, the chemical composition of natural rubber is mainly cis-1,4-polyisoprene, which contains a large number of unsaturated double bonds, which is easy to carry out autocatalytic reaction with oxygen in the air, causing molecular chain scission or excessive crosslinking, Viscosity and cracks occur in rubber, which greatly limits its practical application. Contents of the invention [0003] Based on the technical problems in t...
