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...
