Abstract

A matte paint protection film, the matte paint protection film comprises a transparent support, on an optical surface of the transparent support, a matte self-healing layer and a transparent protective film are sequentially arranged; on the transparent support On the other optical surface of the body, an assembly glue and a translucent release film are sequentially arranged, and the matte self-healing layer is formed by heating and curing after coating the self-healing coating liquid; the self-healing coating liquid contains elastic organic particles , modified polyol resin, curing agent and other components; the particle size of the elastic organic particles is 1 μm to 15 μm; the curing agent is composed of curing agent 1 and curing agent 2, and the mixing ratio is 2:1~ 5:1. The matte paint surface protective film provided by the invention has good matte effect and self-repairing effect, has yellowing resistance and antifouling properties, and can be applied to the field of paint surface 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 order to meet individual needs, the demand for matte paint protection film is now proposed. Generally, there are two methods for the production process of...
