Multi-layer composite thermal insulation acrylic protective film and preparation method thereof

Abstract

The invention discloses a multi-layer composite heat-insulating acrylic protective film and a preparation method thereof. The multi-layer composite heat-insulating acrylic protective film comprises a base material layer, a heat-insulating layer is arranged on the upper surface of the base material layer, an antibacterial and antistatic layer is arranged on the upper surface of the heat-insulating layer, and a protective layer is arranged on the upper surface of the antibacterial and antistatic layer; an anti-blue-ray layer is arranged on the lower surface of the base material layer, a silica gel layer is arranged on the lower surface of the anti-blue-ray layer, an adhesive layer is arranged on the lower surface of the silica gel layer, and a release film is arranged on the lower surface of the adhesive layer. According to the invention, the silica gel layer and the heat insulation layer are arranged, so that a good heat insulation effect can be achieved; by arranging the antibacterial and antistatic layer, the antibacterial and antistatic functions can be achieved, and bacterium breeding is avoided; by arranging the anti-blue-light layer, the anti-blue-light performance of the protective film is enhanced; and the silica gel layer has a certain buffering function, so that the buffering and damping performance of the protective film can be properly improved.

Description

technical field [0001] The invention relates to the technical field related to protective films, in particular to a multilayer composite heat-insulating acrylic protective film and a preparation method thereof. Background technique [0002] According to the application, the protective film can be divided into digital product protective film, car protective film, household protective film, food fresh-keeping protective film and so on. The protective film is used in the processing, storage and transportation of building materials or electrical, electronic products, automobiles, etc. This kind of adhesive film must have good adhesion and can be easily peeled off after use without causing various Surface is contaminated with adhesive. In the production process of the protective film, some colloids need to be used, such as acrylic glue, PU glue and silica gel, etc., and different colloids are used according to the purpose of the protective film. At present, the main types of pr...

AI Technical Summary

Problems solved by technology

[0003] The existing acrylic protective film generally does not have heat insulation effect, or the heat insulation effect is very poor. Therefore, we propose a multi-layer composite heat-insulating acrylic protective film and its preparation method to solve the problems in the prior art
