FIELD: manufacture of transparent laminated materials used for forming transparent barrier in architectural apertures and in automobile windows.
SUBSTANCE: proposed method includes preheating of at least one glass sheet or polyvinylbutyral sheet followed by bonding them by momentary application of pressure with the aid of hold-down rollers, thus forming the laminated glass blank. Polyvinylbutyral sheet contains lesser than 0.35 wt-% of moisture. Then, laminated glass blank is heated to temperature of 115-230°C at pressure of from 1 to 3 atm.
EFFECT: enhanced strength of material without finishing treatment in autoclave.
