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

Embodiment 1

[0042] A kind of non-composite release film is used for the preparation method of the protective film of silver mirror glass laser cutting, comprises the following steps:

[0043] Preparation of the adhesive layer: by weight, 2.2 parts of acrylic acid, 6.5 parts of butyl acrylate, 3.5 parts of lauryl alcohol methacrylate, 2.5 parts of methyl methacrylate, 2 parts of hydroxyethyl methacrylate, 3 parts of methyl Oxymethyl methacrylate, 5 parts of isoprene rubber containing double bonds, and 55 parts of solvent (including 15 parts of acetone, 20 parts of toluene and 20 parts of ethyl ester) were placed in a reaction vessel, and the temperature was raised to 75°C with constant stirring Then, mix 0.25 parts of BPO initiator with the remaining solvent and slowly drop them into the above-mentioned reaction vessel, stir continuously, and continue to react for 3 hours while keeping the reaction temperature constant, and cool to room temperature to obtain acrylate pressure. Sensitive gl...

Embodiment 2

[0048] A kind of non-composite release film is used for the preparation method of the protective film of laser cutting of silver mirror glass, other steps are identical with embodiment 1, and different from embodiment 1 are:

[0049] Preparation of the adhesive layer: by weight, 3.6 parts of acrylic acid, 6.5 parts of butyl acrylate, 4.5 parts of lauryl alcohol methacrylate, 3.2 parts of methyl methacrylate, 2.5 parts of hydroxyethyl methacrylate, 3.5 parts of methyl Oxymethyl methacrylate, 6 parts of isoprene rubber containing double bonds, and 60 parts of solvent (including 15 parts of acetone, 25 parts of toluene and 20 parts of ethyl ester) are placed in a reaction vessel, and the temperature is raised to 80 °C with constant stirring Then, mix 0.45 parts of BPO initiator with the remaining solvent and slowly drop them into the above-mentioned reaction vessel, stir continuously, and continue to react for 3 hours while keeping the reaction temperature constant, and cool to ro...

Embodiment 3

[0051] A kind of non-composite release film is used for the preparation method of the protective film of laser cutting of silver mirror glass, other steps are identical with embodiment 2, and different from embodiment 2 are:

[0052] Preparation of silicone resin layer: 90 parts of hydroxyl-terminated dimethylvinyl (siloxane and polysiloxane), 3.5 parts of hydrogen-terminated poly(dimethylsiloxane), 1 part of modified silane The joint agent was diluted in 230 parts of toluene to obtain a silica gel emulsion, which was coated on the surface of the adhesive layer by the coating bar coating method, and dried at 80°C for 20 minutes until the water evaporated completely to obtain a silicone resin layer, wherein the silicone resin layer The thickness is 2.6 μm.

Abstract

The invention discloses a non-composite release film protective film for silver mirror glass laser cutting. The protective film comprises a functional layer, a film base material layer, an adhesive layer and a silicon resin layer, wherein the adhesive layer covers one side of the film base material, the functional layer covers the other side of the film base material layer, the surface of the adhesive layer is covered with a silicon resin layer formed by silicon resin containing a modified silane coupling agent, the modified silane coupling agent is formed by modifying methyl triisopropoxy silane by N-benzoyl quinine tert-butyl ester, the obtained protective film has excellent heat resistance, water resistance and stain resistance, is used for laser cutting of silver mirror glass, and can effectively protect the silver mirror glass from being damaged by pollutants such as gasified smoke dust and burning and melting fly slag generated in the laser cutting process, so that a product with relatively high yield is obtained; and meanwhile, the protective film can absorb low-energy light focused on the periphery of a light spot by the laser beam, so that the line width of a heat affected zone on the upper surface of the cut material is reduced, and the machining precision of a machined device is improved.

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...
