Problems solved by technology

[0002] From the perspective of the development trend of the domestic automobile industry, the automobile engine cooling system has been using radiators for cooling. The seals between them have not been improved accordingly. With the continuous development of the automobile industry, the performance of the original radiator plate rubber seals of the automobile engine cooling system is not enough to support the market demand, especially the aging resistance and permeability. , wear resistance and other aspects of performance are quite different, which restricts the development of the automobile industry, so how to improve the performance of the radiator plate rubber seal of the automobile engine cooling system is a technical problem to be solved

Abstract

The invention discloses a preparation method of a plate type rubber sealing part of a radiator of an engine cooling system, and relates to the technical field of new materials. The preparation methodincludes the following steps that (1) plasticated rubber is obtained; (2) a doped mixture is obtained; (3) an activating agent, an anti-aging agent, the doped mixture, modified polyaniline, carbon black and stearic acid are added into a plasticator and evenly mixed to obtain a rubber compound; and (4) the rubber compound is added into a mold and subjected to compression molding, and then the molded rubber compound is added into a vulcanizing machine to be vulcanized, so that a finished product is obtained. Through the cooperation effect of the added prepared doped mixture and the modified polyaniline, ozone resistance of the plate type rubber sealing part of the radiator of the engine cooling system can be effectively improved, and thus the using performance and the service life of the plate type rubber sealing part of the radiator of the engine cooling system can be effectively improved and prolonged separately; the prepared rubber sealing part has excellent fuel-oil resistance, and is not prone to degradation or adhesion-damage and leakage.
