Embodiment 1

[0011] The production method of luminous flow pattern EVA laminated glass film includes the following steps, (1) the step of making luminous powder into luminous masterbatch. Molecular wax is used as a dispersant, and the mass concentration of luminous powder is 30%; (2) The step of mixing the luminous masterbatch with EVA resin and coupling agent evenly, and the melt index of EVA resin is 15g / 10min at 190°C; (3) The step of producing EVA glass film by casting film forming process.

[0012] Among them, the polymer wax described in step (1) is selected as polyethylene wax; the coupling agent described in step (2) is selected as aminoethylaminopropyltrimethoxysilane; The film process uses a single-screw extruder with an extrusion temperature of 100°C.

Embodiment 2

[0014] The production method of luminous flow pattern EVA laminated glass film includes the following steps, (1) the step of making luminous powder into luminous masterbatch. Molecular wax is used as a dispersant, and the mass concentration of luminous powder is 45%; (2) The step of mixing the luminous masterbatch with EVA resin and coupling agent evenly, and the melt index of EVA resin is 22g / 10min at 190°C; (3) The step of producing EVA glass film by casting film forming process.

[0015] Among them, the polymer wax described in step (1) is selected as polyethylene wax; the coupling agent described in step (2) is selected as aminopropyltrimethoxysilane; in step (3), the cast film-forming process adopts Single-screw extruder, extrusion temperature is 110°C.

Embodiment 3

[0017] The production method of luminous flow pattern EVA laminated glass film includes the following steps, (1) the step of making luminous powder into luminous masterbatch. Molecular wax is used as a dispersant, and the mass concentration of luminous powder is 65%; (2) The step of mixing the luminous masterbatch with EVA resin and coupling agent evenly, and the melt index of EVA resin is 37g / 10min at 190°C; (3) The step of producing EVA glass film by casting film forming process.

[0018] Wherein, the polymer wax described in step (1) is selected as EVA wax; the coupling agent described in step (2) is selected as vinyltriethoxysilane; in step (3), the cast film-forming process adopts a single Screw extruder, extrusion temperature is 100°C.

[0019] The present invention makes full use of the principle that the luminous masterbatch polystyrene base material is incompatible with EVA resin, the difference in melt viscosity is large, and the luminous masterbatch cannot be unifo...

Abstract

The invention belongs to the technical field of glass film production, and particularly relates to a production method of a luminous flow-line EVA laminated glass film. The production method comprises the following steps: (1) making luminous powder into luminous masterbatch, wherein the base material of the masterbatch is polystyrene with the melt index of 0.5-5 g / 10min at 190 DEG C, high-molecular wax is used as a dispersing agent, and the mass concentration of the luminous powder is 20%-70%; (2) uniformly mixing the luminous masterbatch with EVA resin and a coupling agent, wherein the melt index of the EVA resin is 5-40 g / 10min at 190 DEG C; and (3) generating the EVA resin film by a casting film forming process. In the method provided by the invention, the formed glass film has a flow line effect like marble based on the principles that the polystyrene base material in the luminous masterbatch is incompatible with the EVA resin, the difference in melt viscosity is great and the luminous masterbatch cannot be uniformly dispersed in the EVA resin.

Description

technical field [0001] The invention belongs to the technical field of glass film production, and in particular relates to a production method of luminous flow pattern EVA laminated glass 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. The existing glass film is generally monochromatic, and the laminated glass produced is generally transparent and monochromatic. When it is necessary to show the combined color effect, laminated glass of multiple colors is generally used in combination. However, with the improvement and transformation of people's aesthetic ability, monochrome laminated glass can no longer meet people's aesthetic needs, and people are in urgent need of technologies that can display marble-like flow patterns on the same piece of laminat...
