Problems solved by technology

However, pollutants such as gasification smoke and melting slag generated during the laser cutting process will form large pollution scars after splashing on the surface of the flexible film material, which is very difficult to remove. It cannot be completely removed; therefore, it is very important to coat a protective film on the surface of the glass material

Abstract

The invention discloses a non-composite release film protective film for laser cutting of silver mirror glass; it comprises a functional layer, a film base material layer, an adhesive layer and a silicone resin layer; the adhesive layer covers one side of the film base material ; The functional layer is covered on the other side of the film substrate layer; wherein, the surface of the adhesive layer is covered with a silicone resin layer formed by a silicone resin containing a modified silane coupling agent; wherein the modified silane coupling agent consists of N Benzene Acyl quinine tert-butyl ester modified methyl triisopropoxysilane; the obtained protective film has excellent heat resistance, waterproof and stain resistance protective film, which is used for laser cutting of silver mirror glass, which can effectively Protect the silver mirror glass from the damage caused by gasification smoke, burning slag and other pollutants produced during the laser cutting process, and obtain a product with a high excellent rate; at the same time, the protective film can absorb the low energy of the laser beam focused on the periphery of the spot Light, thereby reducing the line width of the heat-affected zone on the upper surface of the material to be cut, so as to improve the processing accuracy of the processed device.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a non-composite release film protective film used for laser cutting of silver mirror glass. Background technique [0002] At present, laser cutting technology has become a mature industrial processing technology. Metal is the main object of laser cutting, and other materials that can be laser cut include plastics, ceramics, silicon wafers, and glass. Glass With the increasing application of glass, some applications have very strict requirements on cutting quality and cutting yield, and the traditional glass cutting technology has gradually been unable to meet the production requirements. Such as high temperature resistant and high hardness borosilicate glass as TFT-LCD substrate and tempered glass used in automobiles. Now people have thoroughly studied the laser cutting technology of glass, and the superiority of laser cutting has gradually been recogniz...
