Description
Technical field
The present invention relates to a kind of processing methods of bubble-free laminated glass, belong to glass post-processing industry.
Background technique
Laminated glass as a kind of safety glass there is anti-falling function to be widely used in building field currently on the market,
Laminated glass best one kind of performance in safety glass classification, can fall arrest.Especially Shanghai City building curtain wall glass, very
Focus on safety；The 77th command of Shanghai municipal government puts into effect Shanghai City building glass curtain wall management method, and wherein Article 6 requires to need
Cladding glass to be installed at two layers or more, safety interlayer glass or other glass with fall arrest performance should be used.
But on the market we often visible sandwich glass edge comes unglued, the defects of bubble, affect appearance and peace to a certain extent
Entirely, many security risks are brought to building.
Common laminated glass product in the market bonds together two panels or divided glass by intermediate resin material,
Resin material is usually PVB or SGP, two panels or divided glass by first pressing roll-in or is vacuumized, then into autoclave high pressure, most
End form is at laminated glass；2 steps of traditional laminated glass manufacture craft point: first step pre-molding, second step high-pressure molding.Precompressed
Molding: the semi-finished product laminated glass that would be combined into is allowed to form by heating, roll-in.Heating and nipping process make glass and PVB
As an entirety.Twice heating, roll-in are mostly used in flat laminated glass production.First of heating purpose: keep PVB tentatively soft
Change, excludes air convenient for roll-in.First of roll-in purpose: by squeezing the air excluded between glass and PVB.Second heating
Purpose: softening PVB, is convenient for edge sealing.Second roll-in purpose: make glass and PVB bonds together and edge sealing by squeezing, keep away
Exempt from outside air to enter between glass and PVB.Rolling pressure: 3bar-6bar, behind rod cylinder pressure slightly larger than front rod cylinder
Pressure.Because of its different heating temperature of products configuration, transmission speed is variant.High-pressure molding: autoclave category high-pressure bottle is
The most critical equipment of traditional mode of production laminated glass, most up-to-date techniques have cancelled this high-pressure bottle.The thickness and loading of laminated glass
Amount, heating and cooling ability when heavy sheet glass and hybrid thin and thick glass, are processed, laminated glass is in high pressure by the time of heavy sheet glass
In kettle by 125 DEG C~150 DEG C constant temperature, 8bar-15bar constant pressure keeps for 30 minutes or more.In addition the time of heating and cooling,
Generally at 6 hours or so, pressure is kept by gradually cooling down, after temperature drops to 50 DEG C hereinafter, releasing stress completely, Cai Nengkai kettle
Door, is made that transparency is high, cohesive force is strong, the very high laminated glass of mechanical strength.
The processing technology laminated glass product, when being applied to exposed high-temperature high humidity climate area, glass can be irregular
There is edge fault, edge is come unglued, and the open defects such as bubble cause to come unglued between two panels or divided glass when serious, outside
It sees unsightly and security risk；Laminated glass in the market, when carrying out heat resistance test, glass edge come unglued air blister defect without
Method avoids, so as to cause exposed in the outer laminated glass used of high-temperature high humidity climate area building in the market, with using the time
Length, sandwich glass edge is all defective, our frequent visible laminated glass railings, the outer enclosed structure of laminated glass, interlayer glass
Glass lighting roof etc., laminated glass product have open defect and security risk；When carrying out high temperature and humidity test, according to
Laminated glass is put into 100 degree of hot water and boils 2 hours by GB15763.3 heat resistance test experiments, which occurs
The defects of a large amount of edge bubbles come unglued.
Summary of the invention
