Production technique at present for doubling glass mainly contains dry method (i.e. PVB Film Dosimeter) and wet method (i.e. injection process) two kinds.Dry method to refer between two panels or divided glass PVB film on folder, to be then positioned in autoclave pressing under the condition of High Temperature High Pressure and to form the production technique of laminated glass; And wet method fills liquid glue along reserved encapsulating mouth toward the space between two sheet glass after referring to two panels glass enclosure upper sid strip, be then solidified into the production technique of laminated glass.Dry process technique is compared with wet method, and the complete processing of dry method is relatively simple, product performance are better, are also suitable for large-scale production.For the research of all higher doubling glass of how production over-all properties still in constantly carrying out.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide a kind of can obtaining to have the dry method curved toughened rubber-laminated vacuum glass high compared with high impact properties intensity, heat-resisting, heatproof, radioprotective, shielding ultraviolet rays and transparency.
Above-mentioned purpose of the present invention is achieved through the following technical solutions: the production technique of the curved toughened rubber-laminated vacuum glass of a kind of dry method, described production technique comprises the steps:
S1, by curved tempered glass alcohol wipe, be sent to fixed temperature and humidity and close sheet room, carry out conjunction sheet with the PVB glued membrane of well cutting according to level, obtain doubling glass, the level of described conjunction sheet is followed successively by from bottom to top: bottom curved tempered glass, PVB glued membrane, surface layer curved tempered glass;
S2, first carry out three road heating processes by process furnace by closing the good doubling glass of sheet PVB glued membrane is softened, then carry out pressure roller extrusion process the air between curved tempered glass and PVB glued membrane is got rid of completely; Wherein three road heating processes are: first paragraph preheating temperature 140-160 DEG C, second segment Heating temperature 200-230 DEG C, the 3rd section of Heating temperature 200-220 DEG C;
S3, by extruding after doubling glass can obtain curved toughened rubber-laminated vacuum glass as carrying out three sections of temperature-pressure process in air pressure kettle.
The present invention adopts the better curved tempering of performance to do bottom and surface layer glass, middle layer is done with the PVB glued membrane that light transmission, transmittance, sticking power, degree of adhesion are all higher, and first pass through zone heating, be bonded through air pressure kettle temperature-pressure after pressure roller extruding again, air pressure kettle is adopted to pressurize further, make the cohesive force between all-in-one-piece curved tempered glass and PVB glued membrane complete, reach 100%.And PVB glued membrane has very strong ultraviolet ray filtering ability, intercepting ultraviolet rate can reach 99.9%, effectively can prevent ultraviolet radiation fading and destroying various utensil.PVB glued membrane and curved tempered glass are made doubling glass, the ability of its absorption and reflection ray can be improved, effectively can control the transmitance of sunlight, control the transmittance of visible ray.
The heating object of the first in step S2 makes PVB film preliminarily softened, is convenient to excluding air; The heating object of second is that PVB film is softened, and is convenient to edge sealing; 3rd road heating can make PVB glued membrane and bonding glass.After three road heating roll-ins, glass surface temperature requires to reach 50-70 DEG C, and general glass edge, than middle portion temperature height 5-6 DEG C, can reach good edge sealing effect, prevents the infiltration of air from producing bubble.If Heating temperature is too high, the easy variable color of PVB glued membrane, bubble can not be discharged completely; If Heating temperature is too low, PVB glued membrane and glass can not be bonded together completely, and PVB glued membrane and glass can be caused to come off.
Step S3 carries out three sections of temperature-pressure and gas backstreaming in air pressure kettle can be avoided to produce bubble, thus improves the quality of final doubling glass, and under rugged environment, glass and PVB glued membrane difficult drop-off, improve its light transmission simultaneously.
