Liquid crystal display screen IC heat insulation material

Abstract

This invention relates to the field of thermal insulation materials, specifically to a thermal insulation material for liquid crystal display screen ICs. The method includes: bonding a modified graphite thermally conductive film to a release surface to obtain a first-cut semi-finished product; bonding the adhesive side of the thermal insulation film of a third-cut semi-finished product to the adhesive-free side of the first-cut semi-finished product; bonding a composite to the double-sided adhesive side of a second-cut semi-finished product to obtain a fourth-cut composite semi-finished product; firstly, bonding the adhesive-free side of a 0.05T protective film to the adhesive side of a backing film to obtain a fifth-cut semi-finished product; and finally bonding the fifth-cut semi-finished product to the fourth-cut composite semi-finished product to obtain the thermal insulation material for liquid crystal display screen ICs. This invention utilizes a hydrogen peroxide-ammonia solution to treat the graphite film, introducing hydroxyl and carboxyl polar groups onto the graphite surface, effectively breaking its chemical inertness and providing sufficient active sites for subsequent grafting of silane coupling agents. Based on this, the bridging effect of the silane coupling agent is used to uniformly load silver particles onto the graphite film surface.
