Abstract

The utility model discloses a prevent pounding glass, including PVB film and glass piece, its characterized in that: prevent pounding glass includes three glass pieces and six PVB films, and it has three PVB films to bond between per two glass pieces. Through using multi -disc glass piece and multi -disc PVB film to mutually combine together, strengthened PVB intermediate layer glass prevent pound the function and keep warm, control noise and keep apart the ultraviolet ray and all have fine effect because the material that adopts is more ordinary, consequently have simple structure and low in manufacturing cost's advantage.

Description

Prevent pounding glass

Technical field

This utility model belongs to a kind of glass art, concretely relates to a kind of glass having and preventing pounding function.

Background technology

Existing composite intermediate layer glass is to be composited by two-layer or compound glass, although its intensity and the security performance after broken are better than single-glass, but still cannot keep out the apparatus impact of continuous print, great.The material of its use simultaneously is common 5mm former sheet glass+pu film+PC polycarbonate+pu film；This anti-to pound glass manufacture cost relatively high, and anti-pound intensity and limit to some extent.

Utility model content

In view of the presence of problem above, this utility model provides one to be prevented pounding glass, has anti-impact force strong, and has higher feature in sound insulation and noise reduction, heat-insulation and heat-preservation function aspects.

A kind of anti-pounds glass, including PVB film and sheet glass, it is characterised in that: described anti-pound glass and include three sheets and six PVB films, between every two sheets, be bonded with three PVB films.The advantage of the technical program is through using multilamellar PVB film adhering glass sheet, because there is safety after PVB film is bonding with glass, anti-pound, be incubated, the multiple function such as control noise and isolation ultraviolet, make its effect in anti-impact force and sound insulation and noise reduction and heat-insulation and heat-preservation higher simultaneously as the technical program employs 6 PVB films, pound in effect intensity further anti-, simultaneously because adopting simple glass and PVB film is not high cost product, therefore have in advantage lower in cost.

Further: three, described PVB film bonds together with sheet glass after bonding together.This structure is first by bonding with two sheets again after bonding for three PVB films, is then that three PVB films are bonding on the glass sheet again, has simple in construction, advantage easy to make.

Further: the thickness of described every sheets is 5mm, the PVB film stock thickness between every two sheets is 2.28mm.The advantage of this structure adopts common 5mm glass exactly, and strengthens the thickness of PVB film, thus enhancing the toughness of PVB film, anti-pounding the anti-of glass thus enhancing and pounds effect.

Beneficial effect

The beneficial effects of the utility model are: by using plurality of glass sheets and multi-disc PVB film to be together with each other, enhance the anti-of PVB laminated glass pound function and have good effect at insulation, control noise and isolation ultraviolet, material owing to adopting is relatively conventional, the advantage therefore with simple in construction and low cost of manufacture.

Detailed description of the invention

As a kind of embodiment of the present utility model, prevent pounding glass as it is shown in figure 1, a kind of, including PVB film and sheet glass, it is characterized in that: described anti-pound glass and include three sheets 1 and six PVB films 2, between every two sheets, be bonded with three PVB films.PVB film, by polyvinyl butyral resin, is extruded from a kind of macromolecular material of type, unorganic glass has good caking property, has transparent, heat-resisting, cold-resistant, moisture-proof through plasticizer DHA plasticizing, the characteristics such as mechanical strength is high.The advantage of the technical program is through using multi-disc PVB film adhering glass sheet, because there is safety after PVB film is bonding with glass, anti-pound, be incubated, the multiple function such as control noise and isolation ultraviolet, make its effect in anti-impact force and sound insulation and noise reduction and heat-insulation and heat-preservation higher simultaneously as the technical program employs 6 PVB films, pound in effect intensity further anti-, simultaneously because adopting simple glass and PVB film is not high cost product, therefore have in advantage lower in cost.Owing to PVB laminated glass is when being subject to external blow, the effect impacted is absorbed owing to resilient middle layer has, alluvium can be stoped to penetrate, even if glass breakage, also similar araneose crackle in small, broken bits is only produced, its fragment is firmly adhered on intermediate layer, do not come off four dissipate hurt sb.'s feelings, and can be continuing with until change；And due to the divided glass that this structure employing multilamellar PVB film is bonding, this kind of anti-glass of pounding likely can not made damage, anti-theft effect is better simultaneously.

In the present embodiment: described PVB film three layers bonds together with sheet glass after bonding together again.This structure is first by bonding with two sheets again after bonding for three PVB films, is then that three PVB films are bonding on the glass sheet again, has simple in construction, advantage easy to make.

In the present embodiment: the thickness of described every sheets is 5mm, the PVB film stock thickness between every two sheets is 2.28mm.Owing to the thickness of every PVB film is 0.76mm, therefore three bonding rear thickness of PVB film are 2.28mm.The advantage of this structure adopts common 5mm glass exactly, and strengthens the thickness of PVB film, thus enhancing the toughness of PVB film, anti-pounding the anti-of glass thus enhancing and pounds effect.
