Abstract

The invention discloses an engine compartment protective agent as well as a preparation method and application thereof. The engine compartment protective agent is prepared from the following raw materials: a surfactant, a cross-linking agent, organic silicon resin, a catalyst, a preservative and an antibacterial agent. After the engine compartment protective agent is in contact with air, a cross-linking polymerization reaction can be rapidly carried out, an insulating protective film is formed on the surface of a rubber and plastic engine compartment, fine cracks are repaired, rubber and plastic aging is delayed, and short circuit is avoided. Therefore, the service life of engine compartment lines and rubber and plastic can be effectively prolonged, and spontaneous combustion of vehicles caused by aging and short circuit of the lines is prevented.

Description

technical field [0001] The invention belongs to the technical field of protective film materials, and in particular relates to an engine compartment protective agent and its preparation method and application. Background technique [0002] With the increase of the use time and driving mileage of the car, the engine compartment of the car will be worn out. In some cars, there are tiny cracks in the engine compartment circuit, which not only has the risk of electric leakage, but also the cracks will gradually expand, making the engine compartment. The engine is corroded and rusted, seriously affecting the safety of the vehicle circuit. Therefore, it is imperative to develop a kind of engine compartment protective agent. Contents of the invention [0003] The first technical problem to be solved by the present invention is: [0004] Provides an underhood protectant. [0005] The second technical problem to be solved by the present invention is: [0006] A preparation meth...
