Problems solved by technology

Therefore, it cannot play a long-term brightening effect
At the same time, the wear resistance and other properties of the protective film are poor, which cannot meet the practical requirements of the product.
This requires a real transparent protective layer and a material that can also be used for color-changing applications to solve this problem. The biggest problem with this material is that it is difficult to peel off the material and the paint surface if there is no release agent. The special materials for film-forming car clothing are applied before construction to reduce the adhesion between the paint surface and the film-forming material to achieve

Description

technical field [0001] The invention relates to the field of release agents, in particular to a special release protectant for automobile paint film-forming car clothing and a preparation method thereof. Background technique [0002] With the development of my country's automobile industry, automobiles have entered common people's families. Auto decoration, auto repair, auto maintenance and other industries have also entered the development channel of rapid growth. [0003] The surface coating of the automobile body endows the automobile with a beautiful appearance and excellent protection performance, which can improve the use value of the automobile and prolong its service life. Because the environment in which a car is used as a means of transportation is very complicated, it must not only withstand the test of heat, cold, wind, sun, and rain, but also bear the damage of dust, exhaust gas, fuel, road asphalt, mud, and mechanical rubbing. The scientific protection of the...
