Abstract
The invention discloses modified butyl rubber. The modified butyl rubber comprises the following components in parts by weight: 15-40 parts of butyl rubber, 8-15 parts of maleic anhydride, 5-10 parts of sulfonyl chloride, 7-10 parts of plasticizer, 0.5-2 parts of vulcanizing agent, 0.5-1 part of antioxidant, and 20-30 parts of inorganic filler. The modified butyl rubber disclosed by the invention is added with the plasticizer, so that the guarant viscosity is lowered; at the room temperature, the modified butyl rubber has high elasticity and high strength of the common vulcanized rubber; the added vulcanizing agent is produced in a vulcanizing manner, so that the holding power of a product is improved, and the peel strength is better.
Description
Technical field
The present invention relates to a kind of modified butyl rubber, belong to the high performance material field.
Background technology
Isoprene-isobutylene rubber is carried out the halogenation modification become a kind of comparatively ripe isoprene-isobutylene rubber modification technology.Its main products has chlorinated butyl rubber and brominated butyl rubber.Chlorinated butyl rubber has kept that conventional butyl rubbers is low ventilative, outside damping, anti-ozone and the chemical mediator-resitant property, also increased the characteristic that conventional butyl rubbers does not have,, good heat resistance fast as vulcanization rate.
But since the polarity of chlorinated butyl rubber still a little less than, cause the consistency of itself and polar polymer relatively poor.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The modified butyl rubber that the purpose of this invention is to provide a kind of excellent performance.
For achieving the above object, the technical solution used in the present invention is:
A kind of modified butyl rubber, this modified butyl rubber is formed by following weight part:
Isoprene-isobutylene rubber 15-40 part;
MALEIC ANHYDRIDE 8-15 part;
SULPHURYL CHLORIDE 5-10 part;
Softening agent 7-10 part;
Vulcanizing agent 0.5-2 part;
Oxidation inhibitor 0.5-1 part;
Inorganic filler 20-30 part.
Described isoprene-isobutylene rubber is the rubbery copolymer of iso-butylene and isoprene.
Described softening agent is one or more the combination in Vaseline, phthalate compound, the synthetic polyisoprene.
Described vulcanizing agent is sulphur or zinc oxide.
Described inorganic filler is one or more the combination in clay, talcum powder, calcium carbonate, the silicon-dioxide.
Described oxidation inhibitor is sulfenyl phenolate.
Advantage of the present invention: adding among the present invention has softening agent, reduces system viscosity, and when room temperature, it has elastomerics and the high strength of common vulcanized rubber, adds vulcanizing agent and makes with vulcanization production, improves the viscosity of holding of product, and stripping strength is preferably arranged.
