Abstract

The invention discloses a high-strength anti-aging ethylene propylene diene monomer rubber pipe, wherein a used ethylene propylene diene monomer material includes the raw materials in parts by weight: 100 parts of ethylene propylene diene monomer, 15-25 parts of polypropylene, 15-25 parts of an ethylene-octene block copolymer, 0.2-1 part of zinc oxide, 0.3-1.5 parts of stearic acid, 0.5-1.5 parts of bromo-octyl-phenolic curing resin, 0.2-1 part of benzoyl peroxide, 0.05-0.3 part of zinc methacrylate, 15-25 parts of modified nano silica, 5-10 parts of attapulgite, 5-10 parts of nano carbon fiber, 2-5 parts of nylon, 0.5-1.2 parts of an anti-aging agent MC, 0.2-1 part of an anti-aging agent 4020, 2-5 parts of zinc nitrilotiracetate, 0.2-0.9 part of an accelerator, 3-10 parts of a plasticizer, and 1.5-3 parts of a silane coupling agent. The high-strength anti-aging ethylene propylene diene monomer rubber pipe provided by the invention has high strength and good heat resistance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of EPDM rubber hoses, in particular to a high-strength and aging-resistant EPDM rubber hose. Background technique [0002] EPDM rubber has excellent physical and chemical properties, such as flex resistance, low temperature resistance, ozone resistance, weather aging resistance, heat resistance, water vapor resistance, electrical insulation and chemical resistance, etc., made of it Rubber hoses have been used in automobile air conditioning hoses, cooling water pipes, warm air pipes, sunroof drain pipes, cable sheaths, gaskets and other fields. In the process of practical application, the EPDM rubber hose will be in contact with cooling water, hot air, etc. After a long period of use, it will often age, causing the EPDM rubber hose to degrade or harden, or even crack, thus lose its strength and other properties. Contents of the invention [0003] Based on the technical problems in the background technolog...
