Abstract

The invention discloses an ultraviolet-proof invisible car cover film with a self-repairing function and a preparation method of the invisible car cover film. The ultraviolet-proof invisible car coverfilm comprises a TPU base material layer, a self-repairing layer, a protecting silica layer, a PET layer, a pressure sensitive adhesive layer and a release layer, wherein the self-repairing layer, the protecting silica layer and the PET layer are sequentially arranged on the upper surface of the TPU base material layer from bottom to top; the pressure sensitive adhesive layer and the release layer are sequentially arranged from top to bottom. By coating the upper surface of the TPU base material layer with a special self-repairing layer, the TPU layer has excellent functions of preventing doodling and fouling and self preparing; an ultraviolet absorbent is added in the self-repairing layer and the pressure sensitive adhesive layer and realizes mass absorption of ultraviolet rays, so thatthe damage of the ultraviolet rays to car paint.

Description

technical field [0001] The invention belongs to the technical field of car coverings, and in particular relates to an anti-ultraviolet invisible car covering film with self-repairing function and a preparation method thereof. Background technique [0002] With the development of economy, China has become the world's largest automobile consumer. More and more cars have entered thousands of households. In 2016, the production and sales of passenger vehicles in my country were 24.4207 million and 24.3769 million respectively, which are an important part of the automobile market. Simultaneously rising with the automobile consumption market is the automobile maintenance market and automobile clothing. [0003] Invisible car cover originated in the United States. It was first used on F-4 fighter jets to protect the paint surface of the radome. After 1990, it was expanded to the field of racing to protect sponsor icons, ensure the completeness of the car body when it collides, an...
