Abstract

The invention discloses a matt paint face protection film which comprises a transparent supporting body. A matt self-repair layer and a transparent protection film are sequentially arranged on one optical surface of the transparent supporting body, assembly glue and a semi-transparent release film are sequentially arranged on another optical surface of the transparent supporting body, the matt self-repair layer is formed by coating self-repair coating liquid and then heating for curing, the self-repair coating liquid contains elastic organic particles, modified polyol resin, curing agent and other components, particle size of the elastic organic particles is 1-5um, and the curing agent is formed by mixing a curing agent 1 and a curing agent 2 according to a proportion of 2:1-5:1. The mattpaint face protection film is high in matt effect and self-repair effect, has yellowing resistance and antifouling performance and can be applied in the field of paint face protection of 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...
