The utility model is further arranged to：First salient point, the second salient point, which are provided with, to be used to bond the poly- of puigging Urethane tack coat.

By using above-mentioned technical proposal, puigging is bonded in the first salient point, the second salient point using polyurethane tack coat On, adhesive force is stronger, has excellent wearability, chemicals-resistant, oil resistivity, and non-toxic after curing of coating, usability compared with It is good.

The utility model is further arranged to：It is bonded between first glassy layer, the second glassy layer along the first glass Layer, the second glassy layer side surface peripheral direction polyvinyl butyral layer.

By using above-mentioned technical proposal, polyvinyl butyral layer have good tensile strength, bending strength and Higher hardness, it is arranged between the first glassy layer and the second glassy layer, plays effective support performance；And have necessarily Adhesive property, improve the adhesive force in the first glassy layer, the second glass layer.

The utility model is further arranged to：First glassy layer, the second glassy layer circumferential side wall on be coated with aluminium Alloy frame.

By using above-mentioned technical proposal, the vacuum glass needs to coat aluminium alloy in circumferential side wall in use Frame, the vacuum glass is played a good protection, while the security performance of vacuum glass can be strengthened.

The utility model is further arranged to：First glassy layer, the second glassy layer fit with aluminum alloy frame Side wall on be bonded with PVC film two.

By using above-mentioned technical proposal, because the first glassy layer, the second glassy layer are being in contact with aluminum alloy frame The soundproof effect of side wall is poor, and PVC film two has good sound absorption, and PVC film two is bonded in the side wall being in contact, had Help strengthen the sound insulation value of the vacuum glass.

The utility model is further arranged to：First salient point, the thickness of the second salient point are 0.2 ~ 0.3mm, it is described every The thickness of sound-absorbing layer is 0.1 ~ 0.12mm.

By using above-mentioned technical proposal, the first salient point and the second salient point are pico- projections, are reduced to the vacuum glass The influence of glass integral thickness.

The utility model is further arranged to：The thickness of the films of PVC mono- is 0.02 ~ 0.03mm, the PVB films (32) Thickness is 0.04 ~ 0.06mm.

By using above-mentioned technical proposal, the thinner thickness of PVC film one, the transparency of PVC film one is added, reduced pair The influence of the translucency of PVC film one；And the translucency of PVB films is excellent, its thickness is set to be more than the thickness of PVC film one, and PVB films Sound-proofing it is excellent, enhance the sound insulation value of puigging.

In summary, the utility model has the advantages that：

The 1st, first salient point, the second salient point are set between the first glassy layer, the second glassy layer, contributed to the first glass Vacuum layer between layer, the second glassy layer is played a supporting role, and is prepared for having concurrently the vacuum of sound insulation value and structural strength simultaneously Glass；

2nd, the first salient point, the second salient point are connected on the surface of the second glassy layer, the first glassy layer respectively, can influence vacuum The sound insulation value of layer, sets puigging, and puigging prevents sound wave using the PVC film one, PVB films and the PVC film one that are bonded together Propagated at two salient points；

3rd, PVC film two is bonded in the circumferential side wall that the first glassy layer, the second glassy layer are in contact with aluminum alloy frame, is had Help further improve the sound insulation value of the vacuum glass.
