The glyglass of the prior art glued layer of polyethylene butyral (PVB) between two sheet glass, various safe glass are made
Glass and windshield.
Polyvinyl butyral resin (PVB) is the condensation product of polyvinyl alcohol and butyraldehyde, PVB most important application fields at home
It is as intermediate coat and in laminated glass.PVB intermediate coats are squeezed into by polyvinyl butyral resin through plasticizer plasticizing
A kind of high molecular material of type, not only appearance is semitransparent thin film for it, and free from admixture, surfacing, have certain roughness and
Good flexibility, has unorganic glass good cohesive force, has the spies such as transparent, heat-resisting, cold-resistant, moisture-proof, mechanical strength height
Property, it is that interlayer, the most general jointing material of safety glass are manufactured on our times, while in building curtain wall, trick awning, cupboard
Window, bank counter, prison visit the building fields such as window, converter screen and various bulletproof glasses and are also widely used.
Current PVB intermediate coats are still there are the shortcomings that low strength, when it is used for laminated glass as intermediate coat, when
Laminated glass occurs to crush, and PVB intermediate coats can have glass fragment is adhered effect well, so as to prevent fragment arbitrarily drops from pounding
The person of hurting sb.'s feelings, but the larger laminated glass of area is when occurring broken, but since the relative intensity of PVB intermediate coats is relatively low, so that
In not
The glass fragment of large area, which can be supported, causes injures and deaths thing that part occurs.

Further, the ultra-violet absorber is benzophenone compound, benzotriazole compound, salicylic acid
One or more in ester type compound.
Further, the antioxidant is one kind or more in the antioxidant of various Hinered phenols or phosphorous acid esters
Kind.
The preparation method of intermediate film for laminated glasses of the present invention is：Raw material is added by weight in mixer and mixed
Close uniformly, be then kneaded in an extruder, the temperature control of extruder is at 120-150 DEG C, by gained extrudate through being cast, rolling
Form a film, by cooling down, drawing carry out shaping, finally by winding process, up to intermediate film for laminated glasses.
Preferably, the extruder temperature is controlled at 130-140 DEG C.
Present invention additionally comprises a kind of laminated glass, including glass outer, inner layer glass and clamping and glass outer and internal layer
The middle film layer of glass workpiece, it is characterised in that：The middle film layer is above-mentioned intermediate film for laminated glasses.
Compared with prior art, intermediate film for laminated glasses of the present invention, during for laminated glass, has following excellent
Point：
1) strength of glass is high, and stress deformation is few：Compared to Conventional interlayer materials, calculate Wind-Pressure Resistance intensity of load and exceed former monolithic
1.9 times of thickness of glass, PVB doublings are 1.2 times；
2) there is splendid transparency, its yellowness index is less than 2.5, realizes perfect real effect；
3) adhesive property is good：Adhesive property >=3000PSI.
