Problems solved by technology

At present, the commonly used explosion-proof heat insulation film is generally composed of multiple layers such as polyester film layer, metal coating layer, adhesive layer, wear-resistant layer, etc. The production process is complicated, and the film layers are bonded by optical glue.
In the process of use, it is found that the adhesion between layers, peeling force and the quality of the overall film are not ideal, and often need to be replaced after a period of use
In addition, there are defects such as poor transparency, poor weather resistance, insufficient UV protection, poor heat insulation effect, and scratch resistance.

Abstract

The invention discloses a preparation method of a colorful multilayer TPU film. The preparation method comprises the steps of selecting a TPU base film; selecting a target material with a colorful function, and coating one surface of the TPU base film through a magnetron sputtering technology, wherein the thickness is adjusted according to the colorful effect; coating a pressure-sensitive adhesive on the other surface of the TPU, and using a PET release film for protection; attaching the surface, which is coated with the target material, of the TPU to the other TPU base film through composite glue, and enabling the magnetron sputtering layer to be clamped between the two TPU base films; coating the other surface of the TPU with a self-repairing coating, and laminating by using a protective film; curing in a multi-layer composite film curing room; and finally obtaining a micron multi-layer composite TPU colorful protective film. According to the invention, a magnetron sputtering process and a coating process are combined; the problem that the magnetron sputtering surface is poor in adhesive force is solved; and moreover, the product solves the problem that a common TPU paint surface protective film is colorless, and provides the anti-scraping and coating self-repairing functions while meeting the requirement that vast fashionable young people pursue cool color.

Description

technical field [0001] The invention belongs to the field of automobile aftermarket, and in particular relates to a preparation method of a colorful multilayer TPU film. Background technique [0002] With the rapid development of the modern automobile industry, the demand for explosion-proof insulation films for automobiles is increasing day by day. Automobile glass is an important guarantee for drivers to drive safely. The hot weather in summer will cause the interior of the car to heat up at a high speed in a short period of time. There are potential safety hazards and at the same time, it will also cause harm to health. The safety factor of automobile glass, energy saving and consumption reduction. Reduce heat loss in winter, maintain the temperature inside the car, effectively block ultraviolet rays, reduce glare, and ensure safe and comfortable driving. [0003] The car explosion-proof heat insulation film is different from the ordinary car film. In terms of performan...
