Abstract

The invention discloses an anti-corrosion material for automobile radiator intake chambers. The material comprises, by weight, 95 parts to 105 parts of nylon 66, 20 parts to 30 parts of glass fiber, 1.5 parts to 1.9 parts of flexibilizer, 1.2 parts to 1.6 parts of antioxidant, and 1.1 parts to 1.5 parts of hydrolysis resistance agent. A preparation method comprises raw material preparation and mixing preparation. The glass fiber can have the effect on improving the strength of the material, the plasticity of the material can be improved due to the flexibilizer, the oxidization process of polymer can be slowed down due to the antioxidant and the hydrolysis resistance agent, and therefore, the polymer can be smoothly machined, and the service life of the polymer can be prolonged. According to the method, because the ingredients and the content of the ingredients of the material are strictly controlled, the prepared material for the automobile radiator intake chambers has the advantages of being high in corrosion resistance, light in weight, high in strength, long in service life and the like, and is an excellent material for manufacturing the radiator intake chambers.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a corrosion-resistant automobile radiator water inlet chamber material. Background technique [0002] The radiator is an important part of the automobile engine cooling system, and its function is to dissipate the heat absorbed by the coolant in the engine water jacket from the high-temperature parts into the air. Therefore, the performance of the radiator directly affects the heat dissipation effect of the automobile engine, and then has a great impact on the power, economy and reliability of the automobile. With the continuous improvement of the speed and power of automobile engines, the heat load is getting higher and higher, and the requirements for cooling systems are also getting higher and higher. People pay more and more attention to the research of cooling systems including radiators. New technologies and new materials Emerging continuously, car radiators are developi...
