Abstract

The invention discloses a corner connecting material for bonding ethylene-propylene-diene monomer rubber. The corner connecting material comprises, by weight, 13-20 parts of polypropylene; 3-10 parts of ethylene-propylene-diene monomer rubber; 25-35 parts of ultra-high molecular weight SEBS; 25-30 parts of naphthenic oil; 0.1-0.3 part of erucyl amide; 1-5 parts of silicone master batch; 0.1-0.3 part of an antioxidant; 10-18 parts talcum powder; and 1-3 parts of black master match. The corner connecting material for bonding the ethylene-propylene-diene monomer rubber is high in bonding strength and good in using effect.

Description

technical field [0001] The present invention relates to a corner material, in particular to a corner material for bonding EPDM rubber and a preparation method thereof. Background technique [0002] EPDM rubber is an elastomeric material polymerized from ethylene and propylene monomers by adding a small amount of non-conjugated diene. It is characterized in that there are no unsaturated double bonds in the polymer molecular chain, and unsaturated double bonds are introduced into the branch chain. , because of its excellent weather resistance, heat resistance, ozone resistance, acid and alkali resistance, chemical corrosion resistance, excellent processing performance and low compression set, it is the preferred material for the production of automotive sealing strips. [0003] There are a large number of manufacturers in the automotive sealing strip industry, and the requirements for the sealing strip industry are getting higher and higher. It is a domestic problem to apply t...
