Automobile skirt coating

Abstract

The invention relates to an automobile skirt coating comprising the following components in parts by weight: 25-35 parts of polyhydric alcohols, 5-10 parts of maleic anhydride, 10-15 parts of sodium borate, 2-5 parts of methyl methacrylate, 1-5 parts of stannous chloride and 5-10 parts of zirconium oxide. The automobile skirt coating disclosed by the invention is flat, fine and smooth in surface; the gloss retention is greater than 85%; the tensile strength and the elongation at break are superior to those of a PVC (Polyvinyl Chloride) anti-stone-bumping paint; the light resistance and weather fastness of the coating are greatly improved; the automobile skirt coating is convenient to prepare, wearable, beautiful, not easy to fall off, and low in manufacture cost, and can be produced on a large scale; and the automotive trim can be effectively protected.

Description

technical field [0001] The invention relates to the field of automobile processing and manufacturing, in particular, the invention relates to an automobile skirt coating. Background technique [0002] Along with the development of my country's automobiles, especially off-road vehicles, station wagons and sedans to the high-grade direction, prolonging the service life, aesthetics and durability have become an important criterion for people to buy automobiles. However, when the car is running, the lower part of the car body, the bottom plate and the wheel cover are easily damaged by the splashed stones, causing the steel plate to be exposed and corroded. In order to solve this problem, the lower part of the car body can be protected with anti-stone impact paint to buffer the strong impact of stones on the car body. While improving the anti-corrosion ability of the bottom plate, it can also play the role of vibration reduction and noise reduction, and improve the safety of the ...

Problems solved by technology

However, due to the large thickness of the PVC anti-stone chip coating and the rough appearance, it is only suitable for parts that do not have high requirements for appearance, such as the car floor and wheel covers.

The use of PVC anti-stone-chip coatings on the front part of the car, the lower part of the door, and the threshold requires both stone-chip resistance and high decorativeness, which will adversely affect its aesthetics.
