Abstract

The utility model provides nonmetal spectral selection interlayer laminated glass. The glass is formed in a way that a PVB (polyvinyl butyral), EVA (ethylene vinyl acetate) or SGP (sentry glass plug) interlayer is clamped in the middle bonding surface of two pieces of glass, a nonmetal polyethylene terephthalate layer (PET) is clamped between the bonding surfaces of the two pieces of glass, and the PET layer is colorless and transparent. The nonmetal spectral selection interlayer laminated glass has the advantages that the nonmetal transparent interlayer is an organic thin film laminated and compounded by multilayer films without containing metal, and the thickness of the interlayer is only 0.05 mm. On the base of almost no loss of visible light, the nonmetal spectral selection interlayer laminated glass selectively blocks near-infrared and ultraviolet parts of solar spectrum, plays the roles of reducing heat radiation and improving the sunshade effect, so as to realize the purposes of environmental protection and energy conservation.

Description

Non-metal optical spectral selectivity intermediate layer laminated glass

Technical field

The utility model relates to a kind of nonmetal intermediate layer laminated glass, belongs to the glass technology field.

Background technology

Traditional intermediate layer laminated glass, water white transparency but shaded effects are poor; The intermediate layer of shaded effects is arranged usually with metal, easily oxidation, and color is arranged.

Summary of the invention

The utility model provides a kind of nonmetal intermediate layer laminated glass, this laminated glass is the middle faying face at two blocks of glass, accompanies PVB or EVA or SGP intermediate layer, again in the middle of two sheet glass faying faces, accompany nonmetal PETG layer PET, this layer is water white.

Described non-metal optical spectral selectivity intermediate layer laminated glass, at the glass inner side towards the sunlight one side, utilize chemical deposition and physical deposition technique to plate first low-emission coated or for solar control film, again at the middle faying face of two blocks of glass, accompany PVB or EVA or SGP intermediate layer, in the middle of two sheet glass faying faces, accompany again nonmetal PETG layer PET, this layer is water white.

The utility model has the advantages that nonmetal transparent intermediate layer is a kind of organic film that does not contain any metal that is formed by the multilayer film superimposion, thickness only is 0.05mm.It can optionally intercept near-infrared and ultraviolet portion in the solar spectrum on the basis of losing hardly visible light, play the reduction heat radiation, improves the effect of shaded effects, thereby reaches the green energy conservation purpose.

This intermediate layer combines with the intermediate layer that conventional interlayer glass uses, and can be made into the joint product of sandwich type structure.The tradition intermediate layer comprises: PVB, EVA and SGP ionic intermediate layer.

This intermediate layer does not contain any metal level, has avoided oxidized and corrosion, can not shield or disturb radio wave.Color is neutral, just is being considered as water white transparency, low reflection and absorption, high transmission.To the light of wavelength in the 900-1200nm scope, this intermediate layer transmission is near 0%, and reflection effectively reduces heat and passes through near 100%, thereby passing through of effective trap heat improves shaded effects.

Fig. 2 is another kind of structure cutaway view of the present utility model.

The specific embodiment

The utility model is to be middle faying face at two blocks of glass at this laminated glass, accompany PVB or EVA or SGP

intermediate layer

3,4, in the middle of two sheet glass faying faces, accompany nonmetal PETG layer PET5 again, this layer is water white, as shown in Figure 1.

Described non-metal optical spectral selectivity intermediate layer laminated glass, in glass 2 inboards towards the sunlight one side, utilize chemical deposition and physical deposition technique to plate first low-emission coated or for solar control film 6, again at the middle faying face of two blocks of glass, accompany PVB or EVA or SGP

intermediate layer

3,4, in the middle of two sheet glass faying faces, accompany nonmetal PETG layer PET5, this layer is water white, as shown in Figure 2 again, further reduce shading coefficient, improve shaded effects.

In the solar spectral, the weight ratio other parts of the solar energy of 900-1200nm scope are much larger, this part energy barrier just can be reduced sun heat radiation very effectively to be seen through, finally reach the purpose that improves sunshade, this is the outstanding feature of the nonmetal transparent spectral selection intermediate layer laminated glass of the utility model.

Claims
