Plastic film, surface matt film and application thereof

Abstract

The invention provides a plastic film, a surface matt film and application thereof. The plastic film adopts a specific structural design. The most basic structure of the plastic film is as follows: the plastic film comprises a base material layer, an adhesion force reinforcing layer and a matt coating layer, wherein the matt coating layer comprises matrix resin and matt inorganic particles; the base material layer is prepared from polyethylene, polypropylene, polybutylene or a mixture of polyethylene, polypropylene and polybutylene and must contain 1wt%-20wt% of a ethylene-octylene copolymer; the adhesion force reinforcing layer contains the ethylene-octylene copolymer same as the base material layer, a coupling agent and tackifying resin in a weight ratio of 100 to (5-8) to (25-32); and the matrix resin is a mixture of polyolefin resin and polyester resin, the matt inorganic particles are nano-titanium dioxide particles or nano-silicon dioxide particles, and the proportion of the matt inorganic particles to the matrix resin is 1 to (80-85). By virtue of constitution and structure selection, the plastic film with an excellent matt effect is obtained and is further applied to the surface matt film and the mirror surface protection.

Description

technical field [0001] The invention relates to the field of plastic films, in particular to a plastic film with matting effect, and also relates to a surface matting film and its application in mirror surface protection. Background technique [0002] Plastic film is a polymer material widely used in the prior art, which is widely used in industry, agriculture and daily life. In actual use, it is found that it has strong reflective properties. Under strong light irradiation, it has strong reflective properties, and long-term staring will cause discomfort to the eyes. It has become an urgent problem to be solved in the prior art to perform matting treatment on it. It is necessary to select the appropriate composition and matting agent to ensure the comprehensive performance of the plastic film. [0003] Surface matte film is a film layer material composed of plastic film and adhesive, which can have the properties of surface protection, matting and light transmission at the ...

AI Technical Summary

Problems solved by technology

[0004] At the same time, the research and development of the above-mentioned plastic film and surface matting film is essentially to apply to the problem of high reflectivity of the surface protection film in the process of mirror protection

In the prior art, there is no film that is obviously suitable for the surface protection of automobile rearview mirrors. Even if it is specially used in the field, the mirror reflection is too strong and the light intensity is too large. It is dangerous to use it during driving.

The prior art is not clearly aware of this problem, and there is no plastic film and surface matting film that can balance the above-mentioned properties
