Abstract

The invention discloses an anti-corrosion method for an automotive chassis. The method includes the steps that (1) a PANI-asbestos / graphene fiber compound, polymer emulsion, white carbon black, mica, water-based asphalt, zinc phosphate and glass flakes are mixed according to the weight ratio being 50:(100-120):(8-10):(4-6):(18-22):(8-12):(4-6); (2) the automotive chassis is cleaned, and oil stains and rust are removed; (3) a mixture obtained in the step (1) is sprayed onto the automotive chassis; and (4) drying lasts for at least four hours at the temperature of 20-60 DEG C. By the adoption of the method, a graphene / asbestos composite automotive armor is formed on the automotive chassis, all the advantages of graphene fibers are achieved, the impact force of at least 80kg / cm<2> can be borne, and the temperature resistance, hardness and acid and alkali resistance can all meet the specification.

Description

technical field [0001] The invention relates to the field of anti-corrosion technology, in particular to an anti-corrosion method for composite fiber of automobile chassis. Background technique [0002] With the improvement of people's living standards, the role of automobiles in people's lives has become more and more prominent. However, due to the impact of the automotive application environment, such as acid rain, such as deicing agent, it will come into contact with the chassis of the car, resulting in corrosion of the chassis of the car. [0003] With the increasingly serious corrosion of metals, it has brought huge losses to the national economy. At present, the protection of metal equipment is mainly based on the coating of anti-corrosion coatings. Due to the defects of the coating itself, it is difficult to completely prevent oxygen and hydrogen as a physical barrier layer. Ions etc. corrode metals, and most anti-corrosion coatings have a destructive effect on the e...
