Abstract

A kind of car paint protective film, described car paint protective film comprises transparent support body, on an optical surface of described transparent support body, arrange self-healing layer and transparent release film successively; On the other side of described transparent support body An assembly glue and a translucent release film are sequentially arranged on an optical surface, and the self-repairing layer is formed by heating and curing after being coated with a self-repairing coating solution; the components and parts by weight of the self-repairing coating solution are: Reactive polyol resin 30-50, curing agent 10-25, reactive leveling agent 0.5-2.5, metal drier 0.2-0.5, organic solvent 25-60. The automobile paint protection film provided by the invention has durable self-healing properties, yellowing resistance, anti-fouling properties and acid and alkali resistance, and can be applied to the field of paint protection on automobile surfaces.

Description

technical field [0001] The invention relates to the field of film technology, in particular to a paint protection film attached to the surface of an automobile. Background technique [0002] Car paint protection film, also known as "invisible car cover", is a layer of transparent protective film attached to the surface paint of the car to protect the original car paint of the car from damage. This product has strong toughness and self-healing function, which can effectively prevent scratches and sand hits, and also isolates the contact between the car paint and the air, and can prevent acid rain, asphalt, bird droppings, etc. from damaging the paint surface . At the same time, the paint protection film is high-definition and bright, which can improve and protect the color and luster of the car paint surface. [0003] In the prior art, Chinese patent CN 201720602261 discloses an invisible car cover with self-repairing function. By adding an automatic repairing resin layer o...
