Problems solved by technology

[0004] However, the current market products have a certain function of blocking ultraviolet rays, but there is no fully blocking product
Due to the strong penetrating power of ultraviolet rays (200-400nm) and the wide range of peaks, it is difficult to achieve a product that completely blocks ultraviolet rays

Abstract

The invention discloses a preparation method of an ultraviolet full-barrier TPU automobile paint surface protective film. The preparation method comprises the following steps: step 1, treating raw materials; step 2, manufacturing TPU particles; step 3, preparing an original TPU film; and 4, preparing a finished product. A product prepared in the invention has a function of blocking ultraviolet rays in a full wave band, and achieves a zero penetration effect. With the product, the aging of an automobile paint surface is well protected, so the paint surface always looks new. The product provided by the invention is a thermoplastic high-polymer transparent film for protecting the automobile paint surface from damage, is widely applied to automobile surface protection, and can be also applied to aviation equipment such as furniture, high-speed rails and airplanes and top-end luxury cruise ships of the world. The product is measured by a PE950S spectrophotometer, and a measurement result show that the ultraviolet blocking rate of the product is 100% and a total blocking effect is achieved. The product provided by the invention has the effect of comprehensively protecting the automobile paint surface, avoids the aging and fading of automobile paint, and prolongs the service life of original paint.

Description

technical field [0001] The invention belongs to the field of paint surface protection films, and in particular relates to a preparation method of an ultraviolet full-blocking TPU automobile paint surface protection film. Background technique [0002] The current market products have relatively basic functional product functions, such as protection of the appearance of car paint, anti-scratch performance; super anti-corrosion properties; excellent self-recovery properties; certain functions such as stain resistance and easy cleaning. [0003] The current production process in the market is as follows: 1. Using precision casting technology, the TPU particles are made into a TPU original film with uniform thickness and no defects on the surface through the extrusion casting process. 2. Using a coating production line, through precision coating technology, one side of the original TPU film is coated with high-performance pressure-sensitive adhesive and a composite release film; ...
