The present invention relates to a kind of field of plastic products, be specifically related to a kind of modified butyl rubber.
Background technology
Isoprene-isobutylene rubber is elastomeric one, is synthesized by iso-butylene and a small amount of isoprene.Generally be used in and make inside doughnut and auto sound articles for use.Present isoprene-isobutylene rubber replaces pitch so that the name of environmental protection is comprehensively universal.
Isoprene-isobutylene rubber resistance to air loss is good, and it also has chemical proofing, and has shock-absorbing, electrical insulation capability.To sunlight and ozone, there is certain resistivity.But there is very large deficiency equally in isoprene-isobutylene rubber, as production cost is relatively high, the shock resistance of itself is general, in use easily occurs the phenomenon of fracture damage, easily there is decomposing phenomenon at a certain temperature simultaneously, work-ing life is shortened greatly.
Summary of the invention
The object of the present invention is to provide a kind of by absorb fillers, weather resisting agent, shock resistance modification agent, toughner, dispersion agent and thermo-stabilizer in isoprene-isobutylene rubber, high, the good weatherability of isoprene-isobutylene rubber intensity after this is waken up, ageing-resistant, good impact resistance, good toughness, good product quality, heat-resistant stability are good, the modified butyl rubber of long service life.
Technical scheme of the present invention is, a kind of modified butyl rubber, described modified butyl rubber is by isoprene-isobutylene rubber, weighting agent, weather resisting agent, shock resistance modification agent, toughner, dispersion agent and thermo-stabilizer composition, described weighting agent is silicon carbide, described weather resisting agent is thio-2 acid 2 stearyl ester, described shock resistance modification agent is styrene-butadiene copolymer, described toughner is Vinyl Acetate Copolymer, described dispersion agent is ethylene-ethyl acrylate copolymer, described thermo-stabilizer is isooctyl thioglycollate dioctyltin, shared by each composition of described modified butyl rubber, parts by weight are respectively: described isoprene-isobutylene rubber 100 parts, described silicon carbide 30-40 part, described thio-2 acid 2 stearyl ester 3-7 part, described styrene-butadiene copolymer 8-14 part, described Vinyl Acetate Copolymer 12-17 part, described ethylene-ethyl acrylate copolymer 2-5 part, described isooctyl thioglycollate dioctyltin 1-4 part.
In a preferred embodiment of the present invention, shared by each composition of described modified butyl rubber, parts by weight are specially: described isoprene-isobutylene rubber 100 parts, 32 parts, described silicon carbide, described thio-2 acid 2 stearyl ester 4 parts, described styrene-butadiene copolymer 10 parts, described Vinyl Acetate Copolymer 13 parts, described ethylene-ethyl acrylate copolymer 3 parts, described isooctyl thioglycollate dioctyltin 2 parts.
In a preferred embodiment of the present invention, shared by each composition of described modified butyl rubber, parts by weight are specially: described isoprene-isobutylene rubber 100 parts, 38 parts, described silicon carbide, described thio-2 acid 2 stearyl ester 6 parts, described styrene-butadiene copolymer 13 parts, described Vinyl Acetate Copolymer 16 parts, described ethylene-ethyl acrylate copolymer 4 parts, described isooctyl thioglycollate dioctyltin 3 parts.
Of the present invention is a kind of modified butyl rubber, this product is by absorb fillers, weather resisting agent, shock resistance modification agent, toughner, dispersion agent and thermo-stabilizer in isoprene-isobutylene rubber, high, the good weatherability of isoprene-isobutylene rubber intensity after this is waken up, ageing-resistant, good impact resistance, good toughness, good product quality, heat-resistant stability are good, long service life.
