Title:

SELF-ADHESIVE MILLABLE SILICONE RUBBER COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2021/210273

Kind Code:

A1

Abstract:

The present invention relates to a self-adhesive millable silicone rubber composition containing: (A) 100 parts by mass of organopolysiloxane which has, in one molecule, at least two alkenyl groups bonded to silicon atoms, and has an average degree of polymerization of 100 or more; (B) 5-50 parts by mass of reinforcing silica having a specific surface area of 50 cm2/g or more; (C) 0.1-5 parts by mass of an organic silicon compound having an epoxy group and an alkoxy group in one molecule; (D) 0.1-5 parts by mass of an organosilicon compound having an isocyanate group and an alkoxy group in one molecule; and (E) a curing effective amount of a curing agent, wherein the content of an organosilicon compound having a siloxane bond and a benzene ring in one molecule is 0-0.1 parts by mass, and the content of an organic silicon compound having a siloxane bond and an epoxy group in one molecule is 0-0.1 parts by mass. Accordingly, the present invention can provide a self-adhesive millable silicone rubber composition from which a cured product having excellent productivity and adhesive properties can be formed.
