Abstract

The invention discloses an environment-friendly type EPDM (ethylene propylene diene monomer) adhesive for increasing adhesion force between EPDM rubber and curtain lines. The environment-friendly typeEPDM adhesive is mainly prepared from an EPDM mixing glue and a hydrocarbon solvent oil according to a weight ratio of 1 to (2 to 8), wherein the EPDM mixing glue is mixed by the EPDM rubber, a vulcanizer, a crosslinking additive, an adhesive, zinc oxide, stearic acid, carbon black, white carbon black and maleic anhydride-grafted polymer. The environment-friendly type EPDM adhesive has the advantages that the adhesion force between the EPDM rubber and the polyester fiber, vinylon curtain lines as well as manmade yarns is effectively increased; the environment-friendly effect is realized, theproduction of toxic or harmful matters is avoided in the preparation and use process, and the injury to human bodies and environments is extremely low.

Description

technical field [0001] The invention relates to an adhesive formula, in particular to an environment-friendly EPDM adhesive for improving the bonding of EPDM rubber and cords. Background technique [0002] EPDM rubber has excellent aging resistance (including ozone resistance, heat resistance and weather resistance, etc.), good chemical resistance, electrical insulation, impact elasticity, low temperature performance, low density and high filling. And water vapor resistance and other properties, so it is widely used in automotive parts, waterproof materials for building materials, wire and cable sheaths, heat-resistant rubber hoses and other products. EPDM rubber is one of the fastest-growing rubber types in synthetic rubber. Its production capacity and output have been listed as the third among the seven synthetic rubber types, second only to styrene-butadiene rubber and butadiene rubber. However, the main chain molecules of EPDM rubber are in a saturated state, lacking ac...
