Abstract

The invention discloses a heat-resistant barrier film. The heat-resistant barrier film is composed of a base film, an activating layer and a protective film layer, wherein the surface of the base film is bonded to the protective film layer through the activating layer; the activating layer is composed of raw materials including, by weight part, 50-60 parts of acid-base cross-linking agent, 20-30 parts of acrylic resin, 50-60 parts of acrylic monomer, 2-5 parts of photoinitiator, 1-3 parts of dispersing agent, 1-3 parts of coupling agent and 5-10 parts of heat-resistant filler. The invention also discloses a preparation method of the heat-resistant barrier film. By adding the heat-resistant filler, the heat-resistant barrier film can greatly improve the thermal performance and avoid warping caused by heat, thereby improving the use performance and bringing use convenience to users.

Description

technical field [0001] The invention relates to the field of production and processing of protective films, in particular to a high temperature resistant barrier film and a preparation method thereof. Background technique [0002] The existing electronic screen is developing rapidly. The protective film is pasted on the surface of the screen, which can effectively avoid the screen from being scratched and effectively protect the screen. It is used by people and is welcomed by people. The existing protective film not only applies to the electronic screen The surface is also applied to the surface of metal materials to avoid corrosion of metal materials. The protective film has a wide range of applications and provides convenience for people's work and life. [0003] At present, there are many types of protective films on the market, and the barrier film is the most common one, but the heat resistance of the barrier film is poor, that is, cracks or peeling will basically occur...
