Problems solved by technology

If the air is not fully discharged and the edge banding is completed, there will be air bubbles in the final product, which will become a defective product; if the edge banding is not safe, during the high temperature and high pressure step, high pressure air will squeeze into the gap between the film and form an air gap , resulting in failure of the final product
[0005] It can be seen that the traditional sandwich technology is difficult to meet the above-mentioned different requirements of product production

Embodiment Construction

[0027] A kind of novel dry-process laminated glass production process of the present invention comprises the following steps:

[0028] 1) Form a laminated glass module in the combining room;

[0029] 2) Take two pieces of high-temperature-resistant polyester films and wrap them on the upper surface and the lower surface of the laminated glass module respectively, and seal the surroundings of the two high-temperature-resistant polyester films with sealing strips to form a flexible sealing cavity, and the flexible sealing cavity At least one air outlet for vacuuming is opened on the surface;

[0030] 3) Send the flexible sealed cavity into the autoclave, and the autoclave is equipped with a vacuum device, which is connected to the air suction port of the flexible sealed cavity through the pumping pipeline, and the temperature in the autoclave is heated from room temperature to 135°C , heating speed 1~3℃ / min, keep warm for 60~90min, pressurize the pressure in the kettle to 0.7MP...

Abstract

The present invention provides a novel dry laminated glass production process, which comprises: 1) forming a laminated glass module in a sheet laminating chamber; 2) taking two pieces of high temperature polyester films, respectively coating on the upper surface and the lower surface of the laminated glass module, sealing the peripheries of the high temperature polyester films with sealing strips to form a flexible sealing cavity, and arranging at least a gas sucking port for vacuumizing on the surface of the flexible sealing cavity; and 3) conveying into an autoclave, carrying out pressurization and heating treatment through the autoclave, carrying out vacuumizing treatment through a vacuumizing device, discharging the pressure, taking out, and removing the flexible sealing cavity so as to obtain the finished product laminated glass. According to the present invention, the gas discharge of the process is performed through the vacuumizing in the closed environment, and the vacuum gas discharge and the step 2 are combined to achieve the laminated glass product production in the one step; and the vacuumizing gas discharge is performed in the autoclave so as to complete the laminated glass production process in the one-step manner and efficiently produce the high-quality laminated glass.

Description

technical field [0001] The invention relates to a novel dry-process laminated glass production process. Background technique [0002] Laminated glass is made of two or more layers of glass glued together with PVB. When the glass breaks due to external impact, the glass fragments can still be bonded to the PVB film. Therefore, this composite glass has good safety performance. In addition, this kind of glass also has the characteristics of sound insulation and ultraviolet ray insulation, so it is suitable for application in the external enclosure structure and interior decoration of modern buildings, including civil buildings and household bathrooms. [0003] In recent years, with the continuous expansion of the application demand of glass in construction, and the safety characteristics of laminated glass being recognized by more and more people, the market demand for laminated glass products is also greatly increasing, and some need to sandwich metal plates in glass. Some re...
