Abstract

The invention discloses a production method of laminated tempered glass. The production method comprises the following steps: preparing specially-made PVB rubber, wherein the specially-made PVB rubbercomprises the following raw materials in parts by weight: 80-110 parts of polyvinyl butyral, 8-12 parts of polyvinyl formal, 2-5 parts of metallic silver powder, 4-6 parts of polyvinylpyrrolidone, 2-5 parts of tetraepoxypropyl methylene diphenylamine, 3-5 parts of hydroxyl-terminated nitrile rubber epoxy prepolymer, 3-6 parts of polyethylene naphthalate prepolymer, 1-3 parts of polyvinyl alcohol,2-5 parts of plasticizer, 3-8 parts of antioxidant and 2-5 parts of ultraviolet light absorber; and slightly hammering the top surface of tempered glass on an upper layer by using a small wooden hammer, uniformly hammering the tempered glass, and continuously detecting the thickness of the laminated tempered glass by using a thickness detector. The production method is artful in design, reasonable, good in ultraviolet prevention effect, high in strength and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of laminated tempered glass, in particular to a method for manufacturing laminated tempered glass. Background technique [0002] Tempered laminated glass refers to the further safety treatment after the glass is tempered, and the two pieces of glass are bonded together. After the glass is broken, it will not splash and hurt people, which plays a safety role. Laminated glass has high safety. Because the middle layer of the film is tough and has strong adhesion, it is not easy to be penetrated after being damaged by impact, and the fragments will not fall off, and it is tightly bonded to the film. [0003] Because laminated glass has high impact strength and safe use, it is suitable for doors, windows, ceilings, shower rooms, floors and partition walls of buildings, skylights of industrial plants, shop windows, kindergartens, schools, gymnasiums , Private residences, villas, hospitals, banks, jewelry stores,...
