Description
Technical field
The present invention relates to doubling glass, particularly relate to the doubling method of ultra-large type doubling glass.
Background technology
Traditional laminated glass intermediate layer material is polyvinyl butyral acetal (PVB) film, and the producer that produces PVB film also has a lot, and the length of film, thickness, width can come to have made to order as required, and the technique comparative maturity of this processing operates relatively simple.
The SentrygIas@of du pont company (SGP) film is compared with PVB film, SGP film has stronger cementability, its intensity is the more than 5 times of PVB film, and transmittance is also higher than PVB film, has still embodied " glittering and translucent " effect of ultra-clear glasses after multiple glazing interlayer.So both by contrast, the performance of SGP film is better.Because this film only has the production of one of du pont company, the maximum specification of film only has 6300mm * 2134mm.This at more than 10 meters super large doubling glass, just need to splice film for length, if splice badly, in doubling glass, easily occurs bubble, and stitching portion is prone to joint vestige, and this is a hang-up.
Summary of the invention
The invention provides a kind of doubling method of super large doubling glass, can make film stack together, bonding good, and doubling glass is without any splicing vestige.
The doubling method of super large doubling glass, adopt following steps: (1) first docks film weld, two film butt seams are fitted like a glove, (2) again two sheet glass and film stack are closed to sheet, in autoclave, by normal temperature cold-draw, heat, exhaust into doubling and film splices, described cold-draw is to vacuumize under normal temperature, vacuum tightness-0.08-0.1mpa, time is: 2-3 hour, described heat is taken out as under Elevated Temperature Conditions externally, maintain constant continuation of former negative pressure of vacuum and vacuumize, be progressively warming up to 130-136 ℃ when heat is taken out, external pressure progressively rises to 1.25-1.27mpa.
Described heat is taken out and is comprised and add that normal temperature and pressure heat is taken out and the pressurized heat of heating is taken out two continuous stages.
The described normal temperature and pressure heat that adds is taken out as temperature is progressively raised to 80-100 ℃, and outside does not add to depress and vacuumizes.
The described pressurization of heating comprises increasing temperature and pressure, heat-insulation pressure keeping, and the step 3 of a fast cooling step, and described increasing temperature and pressure and heat-insulation pressure keeping hocket, and described fast cooling is to 35-40 ℃, and fast cooling speed is 2.5 ℃ of-4 ℃/min.
The condition that described increasing temperature and pressure and heat-insulation pressure keeping hocket is: 1) be warming up to 78-80 ℃ of insulation 30 minutes, external pressure rises to 0.6-0.7mpa pressurize, 2) be warming up to 110-120 ℃ of insulation 30 minutes, external pressure rises to 1.0mpa pressurize, 3) be warming up to 130-136 ℃ of insulation 70-90 minute, external pressure rises to 1.25-1.27mpa pressurize.
Described fast cooling divides two stages, from 130-136 ℃, by 2.5 ℃ of-4 ℃/min fast coolings to 100 ℃, waits for that pressure is saturated, then according to this rate of temperature fall, continues cooling 35-40 ℃, carries out exhaust.
During described cold-draw, use porous breathable lapping at the limit of two sheet glass portion parcel, and with adhesive tape, gas permeable material is fixed on to glass outer surface.
The present invention is by the joint of film to connecting, and the Technology of taking out, lowering the temperature through change cold-draw, heat, bonds together it well, completes the splicing of film when completing doubling, i.e. film splicing is what in the process of doubling, to complete simultaneously.Because SGP film itself is viscosity, we are not that it is bonding as a whole, but are overlapped, and by changing the technique of doubling, when making doubling, film are docking together.
Overlap joint in can adopt 0.02mm clearance gauge to carry out measuring error, as dock bad, excessive because of gap, will cause finished glass to occur the phenomenon of bubble.After overlap joint is good, film and two sheet glass are merged, by cold-draw, pressurized heat exhausts full doubling and splicing process.
Cold-draw, for improving the effect vacuumizing, is used porous breathable lapping at limit portion parcel, and with high temperature gummed tape, these gas permeable materials is securely fixed in outside glass, to prevent these lappings being drawn onto to interlayer the inside when vacuumizing.
Heat is taken out and is divided into first stage heat and takes out, and does not pressurize; Subordinate phase increasing temperature and pressure, heat-insulation pressure keeping, and the step of fast cooling, by the temperature and pressure in each stage is adjusted, more effective inner air is discharged completely, the gap of film splicing is more closely connected, slowly by the Bas Discharged of monolithic glass inside.By improving the temperature of subordinate phase, can greatly improve the bonding of film and glass in addition.
And at temperature-fall period, general original processing parameter is disposable cooling at a slow speed, glass permeability is bad, some mist degree, and the bonding force of SGP film reduces.The present invention is divided into temperature reduction technology the method for two stage fast coolings instead, has solved the mist degree of glass, makes glass permeability very good.
The present invention is by above-mentioned processing method, the splicing of doubling and film is completed simultaneously, and by the improvement to original doubling technique, air in SGP film splicing gap is got rid of completely, guarantee that the range estimation of finished glass outward appearance naked eyes, less than visible splicing vestige, has improved permeability and the bonding force of glass simultaneously.
