Title:
ANTI-AGING POLAR RUBBER COMPOSITION, PROCESSING METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/011004
Kind Code:
A1
Abstract:
Disclosed by the present invention are an anti-aging polar rubber composition, a processing method therefor and an application thereof, the rubber composition comprises: a rubber matrix and a compounding component; in parts by weight, every 100 parts of the rubber matrix comprise 0-99 parts of highly branched polyethylene P1, 0-100 parts of a reactant P2 of the highly branched polyethylene P1 and a polar monomer, 0-50 parts of a reactant P3 of a copolymer of ethylene and an α-olefin as well as a polar monomer, and 0-50 parts of a reactant P4 of a binary, ternary or higher copolymer of a monoolefin and a diene monomer as well as a polar monomer, the sum of the contents of P1 and P2 being 50-100 parts; P1 is an ethylene homopolymer having a branched structure, and the degree of branching thereof is not less than 50 branches/1000 carbons; the compounding component comprises a vulcanization system. Provided by the present invention is a rubber composition which has both aging resistance and a certain polarity, broadening the usage range of highly branched polyethylene as an elastomer so that the rubber composition is more suitable for circumstances in which there are requirements for polarity-related properties such as adhesion and oil resistance.
