Abstract

The invention relates to a preparation process of a functional adhesive film for laminated glass and its product. The composition and weight ratio are as follows: (1) EVA resin is 92% to 97%, and the VA content in the EVA resin is 24% to 28%. , melt flow rate 20g / 10min~45g / 10min; (2) liquid peroxide crosslinking agent, the content is 0.3%~1.5%; (3) benzophenone UV aging resistance additives, UV aging resistance additives (4) Liquid silane coupling agent, with a content of 0.1% to 1.0%; (5) Rare earth-doped sulfate or aluminate Afterglow powder fluorescent powder, the powder particle size is between 100 nanometers and 20 microns, and the content is 0.5% to 5%; (6) Inorganic materials or pearlite coloring pigments with a temperature resistance above 200 ° C, the powder particle size is between Between 500 nanometers and 20 microns, the content is between 0.5% and 5.0%. Through kneading, granulation, melting and extruding into a film form, the finished EVA film is obtained through pressure roller pressing, cooling and shaping, and winding.

Description

technical field [0001] The invention relates to a preparation process of a functional adhesive film for laminated glass. Background technique [0002] The traditional adhesive film for laminated glass, such as PVG, PVB, EVA, etc., is sandwiched between two pieces of glass, and the glass is bonded together by heating and pressure to become laminated glass. These laminated films have strong adhesion, high adhesion, high flexibility, high transparency, and no foaming. However, although the laminated glass glue made of traditional laminated films has strong safety performance, it has no other special features. function. Contents of the invention [0003] The object of the present invention is to provide a kind of laminated film preparation process that makes laminated glass have more functions in order to overcome the deficiencies in the prior art [0004] In order to achieve the above object, the present invention provides the following technical solution: a preparation pro...
