Abstract

The invention discloses an ethylene propylene rubber material for a sealing part of an automobile heat dissipation system and a production method of the ethylene propylene rubber material and belongs to the technical field of rubber. The rubber material is prepared from the following components in parts by weight: 100 parts of raw ethylene propylene rubber, 5 parts of zinc oxide, 0.5 to 1.5 parts of stearic acid, 3 to 6 parts of an anti-ageing agent, 20 to 30 parts of fast extruding carbon black N550, 10 to 20 parts of semi-reinforced carbon black N774, 3.5 to 7 parts of a cross-linking auxiliary agent Ricon 153D and 5 to 8.5 parts of a vulcanizing agent Perkadox 14-40B-GR. The rubber material disclosed by the invention has excellent high-temperature-resisting performance and can be used for a long time under the condition that the temperature is -50 DEG C to 150 DEG C; meanwhile, the rubber material has remarkable advantages of low temperature resistance and low-compression permanent deformation.

Description

technical field [0001] The present invention relates to the technical field of rubber, and more specifically, relates to an ethylene-propylene rubber for automotive cooling system seals that can be used for a long time under the condition of -50°C to 150°C, and has the remarkable advantages of low temperature resistance and low compression set The material also relates to a production method of the ethylene-propylene rubber material. Background technique [0002] The heat dissipation system is an indispensable and important system in several major systems of a car. In order to avoid engine overheating, it is necessary to cool the engine components working under high temperature conditions to ensure the normal operation of the engine. [0003] Rubber seals are the core components of automobile radiators, and their cooling effect directly depends on the sealing performance of rubber seals. Therefore, the performance requirements of rubber seals for automobile radiators have al...
