Title:
COMPLEX OF SILICA AND ETHYLENE PROPYLENE RUBBER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/237582
Kind Code:
A1
Abstract:
Disclosed are a complex of silica and an ethylene propylene rubber and a preparation method therefor. In the copolymer, the mass content of the ethylene propylene rubber is 5%-98%, and the mass content of the silica is 2%-95%, wherein the ethylene propylene rubber is a copolymer made by the polymerization of ethylene, propylene and an olefin monomer containing an Si-Cl bond. A silicon-chlorine group contained in the olefin monomer containing an Si-Cl bond is introduced into the pendant group of the ethylene propylene copolymer by a copolymerization reaction, and then is chemically reacted with a large number of silicon-hydroxyl groups present on the surface of silica particles, thus the ethylene propylene rubber is firmly bonded with the silica particles by means of chemical bonds, which fundamentally solves the compatibility problem between silica and the ethylene propylene rubber and the stability problem of dispersing the silica particles in the ethylene propylene rubber.
