Problems solved by technology

However, the penetration resistance of SGP laminated glass is not as good as that of PVB laminated glass, which cannot meet the requirements of automotive laminated glass.
[0006] SGP is a viscoelastic material, which has higher hardness and strength than PVB. Adding it to PVB film will significantly reduce the impact resistance and penetration resistance of the film. In addition, during processing, the film is easy to extrude after SGP and PVB are mixed and extruded into a film. Fracture, causing processing difficulties

Abstract

The invention belongs to the technical field of laminated glass, and particularly relates to a waterproof PVB film and a preparation method thereof. The waterproof PVB film prepared in the invention comprises the following raw materials: PVB resin powder, triethylene glycol di-2-ethylhexoate, an antioxidant, an ultraviolet absorbent, a silane coupling agent, a binding power regulator and SGP. Thewaterproof PVB film has good adhesion to glass, presents good waterproof performance, can be widely applied to automobiles, and has remarkable economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of laminated glass, and in particular relates to a waterproof grade PVB film and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of construction and automobile industries, PVB film is also called PVB film or PVB interlayer. It is the best material for making laminated safety glass in the world today. PVB film is made of PVB resin, which is non-toxic, odorless, non-corrosive, non-flammable, and has good light transmission, insulation, weather resistance, wear resistance, water resistance, oil resistance, and aging resistance. Plexiglass has special adhesion and light transmission properties. Therefore, PVB films with high strength and moisture resistance can be widely used in automobiles, buildings, various bulletproof glasses, aerospace vehicles, military instruments, solar cells, composite shock-absorbing steel plates for industry, etc., and the mark...
