Abstract

The invention relates to a production technology of an EVA cross-linked anti-smash film. The production technology comprises: (1) a step of preparing masterbatch, wherein the base material of the masterbatch is EVA having a melt index of 5-15g / 10min at 190 DEG C, and high molecular wax is adopted as a dispersing agent; (2) a step of uniformly mixing the masterbatch with EVA resin and a coupling agent, wherein the EVA resin has a melt index of 5-15g / 10min at 190 DEG C; (3) a step of generating an EVA glass film by a casting film forming technology; (4) a step of coating: applying the two layersof EVA films obtained by the step (3) to two sides of a layer of PET (polyethylene terephthalate) film, wherein the thickness of the PET film is 0.1-0.15mm. The invention provides a production technology of the EVA cross-linked anti-smash film, wherein by adopting the EVA material to replace traditional PVB (polyvinyl butyral) material and designing a three-layer structure with the EVA films on two sides and the PET film at the middle, the structural strength of the anti-smash film is enhanced; when the EVA cross-linked anti-smash film is applied to glass, the glass ability of resisting strong impact force can be remarkably improved while the peel strength and the tensile strength between the EVA cross-linked anti-smash film and the glass are enhanced.

Description

technical field [0001] The invention relates to a production process of an EVA cross-linked anti-smashing film. Background technique [0002] In the field of architectural decoration, laminated glass has been more and more widely used due to its excellent characteristics such as beauty and firmness. Laminated glass includes a glass film layer in the center and glass on both sides. Anti-smash / explosion-proof glass is a new type of special glass product with a sandwich structure formed by compounding glass film into the middle of two layers of glass, after high temperature and high pressure gluing. The existing anti-smash film has low structural strength, low peeling strength and tensile strength with glass. Contents of the invention [0003] The present invention provides a kind of production technology of EVA cross-linked anti-smashing film to solve the technical problems existing in the known technology, and solves the problems existing in the background technology.
