Detailed description of the invention
Fig. 1 is the flow diagram of the adhesive method of double glazing of the invention.
Fig. 2 is the flow diagram of another embodiment of the adhesive method of double glazing of the invention.
Specific embodiment
Referring to Fig. 1, its flow diagram for the adhesive method of double glazing of the invention.As shown, the double-deck glass
The adhesive method of glass comprises the steps of:
Preheating step S1: the glass cement heating to two panels strengthened glass and between two panels strengthened glass, so that two
Piece strengthened glass and glass cement are warming up to a predetermined temperature；And
Laser heating stepses S2: a laser light illumination glass cement is utilized, so that glass cement rises to a melting by predetermined temperature
Temperature and be changed into a molten condition, the glass cement for being rendered as molten condition then can mutually be binded with two panels strengthened glass；Wherein,
The efficiency that strengthened glass absorbs laser light absorbs the efficiency of laser light lower than glass cement.
In practical applications, what the predetermined temperature was less than the strengthened glass moves back reinforcing temperature, that is to say, that strengthens
Glass is under the predetermined temperature, the problem of acute variation can't occur for intensity, and strengthened glass will not move back reinforcing.
By taking the common strengthened glass in current market as an example, moving back reinforcing temperature is probably 400 DEG C~450 DEG C, and in above-mentioned steps S1
Predetermined temperature may preferably be 270 DEG C~280 DEG C.
The actual embodiment mode of step S1, such as can be the two panels strengthened glass for being coated with glass cement, it is set to baking
In oven, two panels strengthened glass and glass cement is made to be heated to the predetermined temperature in a manner of hot air circulation.Certainly, according to practical
The demand of production is not limited to execute step S1 using oven.
The wavelength of the laser light described in step S2 can be between 800 nanometers to 1500 nanometers, and but not limited to this.In reality
When border executes step S2, the difference of the melting temperature and the predetermined temperature is no more than 350 DEG C, whereby, will can effectively avoid
Between strengthened glass and glass cement because the problem of temperature difference is excessive, and strengthened glass ruptures.In practical applications, in step
During rapid S2, it can be using oven and control the temperature of strengthened glass, and be maintained at the temperature of strengthened glass
It is not more than 350 DEG C with the temperature difference of glass cement.
It illustrates, if two panels strengthened glass and glass cement is not made to be first heated to predetermined temperature, and directly utilizes
Laser light heats glass cement, then in the case where the temperature difference of strengthened glass and glass cement is excessive, and will lead to reinforcing
The problem of glass ruptures.Therefore, the adhesive method of double glazing of the invention, by the cooperation of step S1 and step S2,
When glass cement can be effectively avoided being heated by laser light, strengthened glass ruptures because excessively high with the temperature difference of glass cement
