Abstract

The utility model discloses a compound explosion -proof cavity glass, including A toughened glass, PVB intermediate layer, B toughened glass, C toughened glass, sealed dull polish adhesive tape, inboard plane of A toughened glass and B toughened glass outside plane are passed through the PVB intermediate layer and are bondd, border position adhesion joint strip between inboard plane of B toughened glass and the C toughened glass outside plane, the utility model discloses a bonding PVB intermediate layer in the middle of A toughened glass and the B toughened glass, can the effectual glass of preventing when receiving external striking, prevent the alluvium to pierce through, and its piece firmly the adhesion keep its wholeness on the intermediate level to reach the blast proof security performance of theftproof, PVB laminated glass can restrain the propagation of noise effectively simultaneously, inert gas layer characteristic between B layer toughened glass and the C layer toughened glass are that conducting power is poor, and the cold is not led yet in not heat conduction, can play the heat preservation effect well.

Description

A kind of composite anti-explosion double glazing

Technical field

The utility model relates to a kind of glass, refers more particularly to a kind of composite anti-explosion double glazing.

Background technology

At present, increasing laminated glass, heat insulation glass are applied to the technical fields such as productive life, but in the face of antitheft, broken glass fragment afterwards that everyday home life glass is common drop the safety issue of hurting sb.'s feelings and be not incubated, the problem simple glass such as not sound insulation all effectively can not reach extraordinary effect simultaneously.

Utility model content

Technical problem to be solved in the utility model, it is the technical deficiency for above-mentioned existence, provide a kind of composite anti-explosion double glazing, adopt A toughened glass and B toughened glass intennediate bond PVB interlayer, because elastomeric PVB interlayer has the effect absorbing and impact, can effectively prevent glass when being subject to external blow like this, alluvium is stoped to penetrate, only produce similar araneose crackle in small, broken bits, and its fragment adheres on the intermediate layer securely, can not come off and four loose to hurt sb.'s feelings, PVB laminated glass is very tough and tensile simultaneously, even if occur that glass strikes by robber to split, because PVB layer adheres to each other firmly with glass, still keep globality, robber is made to enter indoor, guardrail can be saved after laminated glass is installed, not only save money but also attractive in appearance, because PVB layer also has the damping function to sound wave, PVB laminated glass can suppress the propagation of noise effectively, form layer of inert by sealing frosted adhesive tape and boning and be filled with rare gas element between interlayer between B toughened glass and C toughened glass, layer of inert feature is that transmissibility is poor, and not heat conduction also not conduction cooling, can play insulation effect well.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: comprise between A toughened glass inner side plane and B toughened glass medial plane and being bondd by PVB interlayer; Adhesion joint strip between B toughened glass inner side plane and C toughened glass medial plane edge.

Further optimization the technical program, described PVB interlayer (2) is a kind of by polyvinyl butyral resin macromolecular material, and thickness is 1.52mm.

Further optimization the technical program, described sealing frosted adhesive tape width is 5mm, thickness 1mm.

Further optimization the technical program, can be filled with rare gas element between described B toughened glass and C toughened glass becomes layer of inert.

Compared with prior art, the utility model has the following advantages: 1, adopt A toughened glass and B toughened glass intennediate bond PVB interlayer, because elastomeric PVB layer has the effect absorbing and impact, can effectively prevent glass when being subject to external blow like this, alluvium is stoped to penetrate, only produce similar araneose crackle in small, broken bits, and its fragment adheres on the intermediate layer securely, can not come off and four loose to hurt sb.'s feelings; 2, PVB laminated glass is very tough and tensile simultaneously, splits, because PVB layer adheres to each other firmly with glass, still keeps globality, make robber enter indoor even if occur that glass strikes by robber, can save guardrail after installing laminated glass, not only saves money but also attractive in appearance; 3, because PVB layer also has the damping function to sound wave, PVB laminated glass can suppress the propagation of noise effectively; 4, the layer of inert feature between B layer toughened glass and C layer toughened glass is that transmissibility is poor, and not heat conduction also not conduction cooling, can play insulation effect well.

Accompanying drawing explanation

Fig. 1 is the structural representation of composite anti-explosion double glazing.

In figure, 1, A toughened glass; 2, PVB interlayer; 3, B toughened glass; 4, C toughened glass; 5, frosted adhesive tape is sealed; 6, layer of inert.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.

Embodiment one: shown in composition graphs 1, is bondd by PVB interlayer 2 between A toughened glass 1 inner side plane and B toughened glass 3 medial plane; Between B toughened glass 3 inner side plane and C toughened glass 4 medial plane, edge adhesion joint strip 5 makes its middle layer form a seal cavity; B toughened glass 3 and C toughened glass 4 seal cavity are filled with rare gas element and form layer of inert 6.

PVB film is clamped between upper toughened glass 1 and middle toughened glass 3, PVB interlayer 2 between upper toughened glass with middle toughened glass is become and by its A toughened glass 1 together with B toughened glass 3 strong bond after heating and pressurizing, elastomeric PVB interlayer 2 has the effect absorbing and impact, can effectively prevent glass when being subject to external blow like this, alluvium is stoped to penetrate, only produce similar araneose crackle in small, broken bits, and its fragment adheres on the intermediate layer securely, can not come off and four loose to hurt sb.'s feelings; PVB laminated glass is very tough and tensile simultaneously, splits even if occur that glass strikes by robber, and PVB interlayer 2 adheres to each other firmly with A toughened glass 1 and B toughened glass 3, still keeps globality, makes robber enter indoor; Because PVB interlayer 2 also has the damping function to sound wave, the propagation of noise effectively can be suppressed; Then protect to arrange along edge between glass 4 at B toughened glass 3 and C steel and seal frosted adhesive tape 5, seal frosted adhesive tape 5 after heating and melting by B toughened glass 3 and C toughened glass 4 welding, intermediate formation sealing air layer, with evacuator by the air of the inside extract out while and be filled with rare gas element, thus between B toughened glass and C toughened glass, form a layer of inert 6, layer of inert feature is that transmissibility is poor, not heat conduction also not conduction cooling, thus insulation effect can be played well.

Should be understood that, above-mentioned embodiment of the present utility model only for exemplary illustration or explain principle of the present utility model, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.In addition, the utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
