Abstract
The invention discloses modified butadiene styrene rubber. The modified butadiene styrene rubber consists of butadiene styrene rubber, a reinforcing agent, a dispersing agent, a flexibilizer, a tackifier, a coupling agent and a plasticizer, wherein the reinforcing agent is super abrasion furnace black N110; the dispersing agent is ethylene distearamide; the flexibilizer is polyvinyl acetate; the tackifier is hydrogenated rosin resin; the coupling agent is vinyl tri(beta-methoxyethoxy) silane; and the plasticizer is dibutyl phthalate. According to the product, the reinforcing agent, the dispersing agent, the flexibilizer, the tackifier, the coupling agent and the plasticizer are added into the butadiene styrene rubber, so that the obtained modified butadiene styrene rubber has characteristics of high strength, convenience in processing, good elasticity, small shrinkage, good tear resistance, good viscidity and good dispersion.
Description
Technical field
The present invention relates to a kind of field of plastic products, be specifically related to a kind of modified styrene butadiene rubber.
Background technology
Styrene-butadiene rubber(SBR), also known as polystyrenebutadienes multipolymer.Its physical mechanism performance, the use properties of processing characteristics and goods is close to natural rubber, some performance is as wear-resisting, heat-resisting, ageing-resistant and vulcanization rate is more excellent compared with natural rubber, can use with natural rubber and various synthetic rubber, be widely used in the fields such as the production of tire, adhesive tape, sebific duct, electric wire, medical apparatus and various rubber item, being maximum general purpose synthetic rubber kind, is also one of rubber clone realizing suitability for industrialized production the earliest.
Pure styrene-butadiene rubber(SBR) intensity is low, can use after needing to add high reactivity strengthening agent; It is larger than natural rubber difficulty that styrene-butadiene rubber(SBR) adds Synergist S-421 95, and Synergist S-421 95 is bad dispersibility in styrene-butadiene rubber(SBR); Transconfiguration is many, with phenyl ring on hand hay cutter base.Thus hysteresis loss is large, and heat-dissipating is high, and elasticity is low, and winter hardiness is also slightly poor, but oil-filled after can reduce heat-dissipating; Shrink large, green strength is low, and viscosity is poor; Vulcanization rate is slow; Flex cracking resistance natural rubber is good, but crack propagation velocity is fast, hot tear crack poor performance.
