Problems solved by technology

At present, most of the coating products used in automobile engine compartments are emulsified by a certain proportion of polysiloxane and deionized water. The system is water-based glazing with good brightness, but the formed siloxane will not After curing, the durability of the protective film is not good and it is not resistant to cleaning with detergent, and the polysiloxane has a high viscosity and the surface to be applied is still easy to stick to dust, and the gloss decreases linearly. The durability of this type of coated product is about 15 days

Abstract

The invention discloses an automobile engine cabin coating agent and a preparation method thereof. The automobile engine cabin coating agent is prepared from the following raw materials in percentageby weight: 70 to 90 percent of isopropanol, 1 to 3 percent of a leveling agent, 1 to 3 percent of a wetting dispersant, 7 to 23 percent of organic silicon resin and 0.1 to 1 percent of a preservative.According to the automobile engine cabin coating agent, organic silicon resin is used as a carrier, the automobile engine cabin coating agent can be cured at normal temperature, and has the characteristics of high film brightness, high hardness, good durability, excellent antifouling effect and the like; long-acting lasting protection is provided for the outer surface of an engine cabin, the constructed cabin surface has the characteristics of brightness, smoothness and pollution prevention, cabin aging, yellowing, cracking and the like are delayed, the later maintenance cost is reduced, thecabin can be bright as new only through simple washing, a formed film layer is transparent after being cured, and the original color and glossiness of the cabin are not affected.

Description

technical field [0001] The invention relates to the technical field of spray coating, in particular to a coating agent for an automobile engine compartment and a preparation method thereof. Background technique [0002] Automobiles are one of the modern means of transportation, and the use of automobiles is becoming more and more common. Due to the continuous operation of the combustion chamber of the automobile engine, the casing of the automobile engine has always maintained a high-temperature working state. The cabin of the automobile engine is prone to decrease in gloss with the prolongation of use time, and dust, oil and other dirt adhere to the surface. If it is not cleaned and maintained in time, It may corrode the parts of the engine, and serious problems such as rust, aging, and cracks may occur. Therefore, it is very necessary to coat the surface of the engine compartment with a film layer, so that the surface of the engine compartment is not easy to be stained wi...
