Problems solved by technology

[0003] However, in the process of attaching the invisible car cover, stretching construction is required, but the tensile modulus of some invisible car covers is too large, and horizontal stripes or fogging are prone to occur during the stretching process, resulting in difficult construction
In addition, during use, when the car cover is exposed to branches, sand, scratches, etc., there will be scratches, which will affect the appearance

Abstract

The invention provides a wear-resistant and deformation-resistant invisible car cover. The wear-resistant and deformation-resistant invisible car cover comprises a substrate, one side of the substrate is covered with a top coating, the side, away from the substrate, of the top coating is covered with a first release film, the other surface of the substrate is covered with an adhesive layer, and the side, away from the substrate, of the adhesive layer is covered with a second release film; the top coating is prepared from a top coating liquid, and the top coating liquid is mainly prepared from the following raw materials in parts by weight: 100 parts of oligomer polyol, 10 to 600 parts of diisocyanate, 1 to 30 parts of a chain extender, 0 to 10 parts of a modifier, 0.05 to 5 parts of a filler, 0.1 to 5 parts of an auxiliary agent, 0.05 to 2 parts of a catalyst and 20 to 1000 parts of a solvent. The invisible car cover has the properties of wear resistance, deformation resistance, yellowing resistance, acid and alkali resistance and high toughness, and can effectively protect a car paint surface.

Description

technical field [0001] The invention relates to a wear-resistant and deformation-resistant invisible car cover. Background technique [0002] The integrity of the car paint is of great significance to the appearance and value preservation of the car. Compared with traditional methods such as waxing, sealing glaze, and coating, the invisible car coating (also known as automotive paint protection film) technology uses functional polymer films to attach to the surface of the car paint to reduce the damage to the car caused by ultraviolet rays, friction, and impact. Impact, high-quality invisible car cover can achieve long-lasting protection without damaging the car paint. [0003] However, in the process of attaching the invisible car cover, stretching construction is required, but the tensile modulus of some invisible car covers is too large, and horizontal stripes or fogging are prone to occur during the stretching process, which makes construction difficult. In addition, d...
