Technical field
The invention belongs to doubling glass technical field, in particular to a kind of processing technology of doubling glass.
Background technique
Doubling glass be by two panels or divided glass, between pressed from both sides one or more layers organic polymer intermediate coat, by spy
After different high temperature precompressed (or vacuumizing) and high-temperature high-pressure craft processing, it is integrated glass and intermediate coat permanent adhesive compound
Glass product.
Currently, there are mainly two types of the production methods of doubling glass.First is that by polyvinyl butyral (PVB) plateholder two
It among layer or compound glass, is put into hot pressing in autoclave and forms, claim " film pressure sintering " or " dry method ", be suitable for industrial metaplasia
It produces.Second is that by among prepared binder slurry filling to the two panels or divided glass for having got togather mould, by heating polymerization or
Illumination polymerize and doubling glass is made, and claims " grouting method " or " wet process ".Since the product of grouting method production technology is lacked there are many
Point, use is less, and therefore, common doubling glass mainly uses " dry method " production technology.
Wherein, doubling glass needs first to heat the glass of film two sides with electric furnace in hot pressing, and to glass
It is vacuumized between glass and film, heat is transferred at film by glass, and subsequent film is endothermic melting and under the effect of the pressure
Firmly it is adhered on glass.However, in the actual operation process, it is even that electric furnace uneven heating occurs to the heating of glass often
Situation, and then lead to the burn-off rate of film and degree difference, film is influenced to the adhesive effect of glass.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of processing technology of doubling glass,
Film can be promoted uniformly to absorb heat and rapid melting, film is realized to the strong bond of tempered glass, increase the knot of doubling glass
Structure stability and safety.
To achieve the above object, the present invention provides the following technical scheme that
A kind of processing technology of doubling glass, comprising the following steps:
1., the size that takes original sheet glass to be cut into setting obtain sheet glass using glass edge-grinding machine to its edging；
2., sheet glass is placed in annealing furnace to progress tempering processing, obtain tempered glass；
3., with ultrasonic cleaning tempered glass, dried after cleaning tempered glass；
4., the tempered glass that takes muti-piece clean, if placing wafer between the adjacent tempered glass of every two carries out conjunction piece, from upper
It is successively denoted as the first glassy layer, doubling layer, the second glassy layer under and, obtains doubling glass unit；
5., doubling glass unit is placed in 2.0-2.4kg/cm2Negative pressure of vacuum in, 140- is heated to it using ultrasonic wave
150 DEG C, while air pressure constant is kept, preheat precompressed 10-15min；
6., by after preheating precompressed doubling glass unit be sent into rolling equipment in, roll temperature be 160-180 DEG C, roll-in
Speed is 5-6m/min, obtains doubling glass crude product；
7., doubling glass crude product be placed in vacuum-pumping density in high-temperature resistant membrane be sealed to 2.5-3.0kg/cm2Simultaneously pressure maintaining afterwards, send supreme
It presses in kettle, is warming up to 140 DEG C and is forced into 7.0-8.0kg/cm2, heat-insulation pressure keeping 0.5-1h；
8., be taken out from the autoclave doubling glass crude product, doubling glass crude product is cooled to room temperature using convection current, cooling time is

2-3min is held, inside glass stress is eliminated by the deformation of itself, then makes it quickly and is uniformly cooled to room temperature, this glass
When glass is in internal tension, the external stress state being pressurized, once breakage locally occurs, the release of stress, glass will occur
It is fractured into the fritter of countless not sharp corners, is not easy to hurt sb.'s feelings, therefore there is better safety.
Further, step 2. in, the tempered glass tempering processing before to its surface grinding process.
By using above-mentioned technical proposal, grinding process can increase the surface roughness of tempered glass, after film fusing
It can preferably tamp on the buffed surface of tempered glass, increase the contacts contact face of film and tempered glass to a certain extent
Product, to increase the bonding firmness of the two, so that doubling glass obtained has good structural stability and safety.
Further, step 4. in, the film by 70-80 parts by weight EVA, 5-10 parts by weight cellulose and 10-
24 parts of insulation particle squeezes out tabletting after mixing evenly and is made.
By using above-mentioned technical proposal, EVA is ethylene-vinyl acetate copolymer, has good flexibility and elasticity,
It, with tempered glass strong bond, can provide good buffer function under the action of cellulose for tempered glass.EVA chemistry
It has good stability and anti-aging and resistance to ozone intensity is good, therefore be applied to good stability in doubling glass and peace
Quan Xing.Since film needs are Nian Jie with tempered glass sealing, often heat insulation is poor, the insulation particle energy in the application
It is enough that one layer of thermal insulation layer is formed in film, it is effectively improved the heat insulation effect of doubling glass, so that doubling glass has green energy conservation
The characteristics of.
Further, the insulation particle has core-shell structure, including shell and kernel, and the shell is EVA, and kernel is
The mixture of sound-proof material and nano material, and the weight ratio of shell and kernel is 1:3.
By using above-mentioned technical proposal, the EVA shell of insulation particle is identical as the main component in film, facilitates interior
Core is more uniform to be scattered in film.Sound-proof material has good sound-insulating and heat-insulating effect, makes nano material in film with this
The heat of middle absorption can be preferably locked in sound-proof material, have the characteristics that structure is simple, thermal insulation and sound insulation effect is excellent.
Further, the nano material is one of tin-doped indium oxide, fluorine-doped tin oxide, Al-Doped ZnO or a variety of
