Embodiment Construction

[0033] The present invention will be further described below with specific embodiment:

[0034] A prescription for preparing high-strength PVB sheets is made up of the following components (parts by weight):

[0035] PVB film scraps: 350-1000 copies;

[0036] Adhesive strength control agent: 0.04 to 0.2 parts;

[0037] Antioxidant: 0.5~2 parts;

[0038] UV absorber: 0.5 to 2 parts;

[0039] Fluorescent whitening agent: 0.004~0.014 parts;

[0040] Plasticizer: 10-60 parts;

[0041] PVB resin: 20-120 parts;

[0042] Chain extender: 1-8 parts.

[0043] Above: the plasticizer is: 3GO or DBS;

[0044] The bonding strength control agent is: an organic acid with a boiling point above 200°C;

[0045] Antioxidants are: Antioxidant B-900 or Antioxidant 1010;

[0046] The ultraviolet absorber is: ultraviolet absorber UV-327 or UV-326;

[0047] Chain extenders are: phthalic anhydride or diisocyanate;

[0048] The fluorescent whitening agent is: fluorescent whitening agent OB or...

Abstract

The invention belongs to the technical field of thermoplastic high molecular materials, particularly relates to a formula for preparing a high-strength PVB (Polyvinyl Butyral) sheet. The high-strength PVB sheet comprises the following substances in parts by weight: 350-1,000 parts of PVB rubber sheet scrap, 0.04-0.2 part of bonding strength control agent, 0.5-2 parts of antioxidant, 0.5-2 parts of ultraviolet absorber, 0.004-0.014 part of fluorescent whitening agent, 10-60 parts of plasticizer, 20-120 parts of PVB resin and 1-8 parts of chain extender. The formula has the beneficial effects that high-boiling-point organic acid is added to serve as the bonding strength control agent, the PVB rubber sheet scrap is efficiently recycled to reproduce the PVB sheet and bonding performance of the PVB sheet and inorganic glass is reasonably adjusted, so that the produced PVB sheet completely meets quality requirements; and phthalic anhydride is added to serve as the chain extender, mechanical property of the PVB rubber sheet is greatly improved, so that the technical indexes of the produced PVB sheet reach and even exceed the advanced world standard.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic polymer materials, in particular to a formula for preparing high-strength PVB sheets. Background technique [0002] There are two types of safety glass: tempered glass and laminated glass. After heat treatment, ordinary glass becomes tempered glass, and its strength is enhanced by four times. However, tempered glass is only a "relative" safety glass, because when there is external impact It will still break and fly off, and tempered glass has a certain percentage of self-explosion rate, even if there is no external impact, it may suddenly shatter by itself; laminated glass is another kind of safety glass, which is made of two layers of ordinary glass. A special glass made of a layer of polyvinyl butyral (PVB) film sandwiched between them. This film is a polymer formed by the condensation reaction of higher molecular weight polyvinyl alcohol and butyraldehyde. A polymer material formed by pl...
