Problems solved by technology

[0004] This invention has low energy consumption and can be produced by hand, but it has the following disadvantages: Since PVB film needs to be embedded around the upper and lower two pieces of glass during operation, if there is a gap, liquid leakage is prone to occur, and the operation is inconvenient, so it cannot meet large quantities. production needs

Embodiment 1

[0040] Embodiment one: a kind of air extraction device, such as figure 1 As shown, it includes a plastic bag 1 and an air pumping assembly 2 installed thereon. The air pumping assembly 2 is connected to an external vacuum pump to vacuum the inside of the plastic bag 1 .

[0041] refer to figure 2 , The plastic bag 1 is provided with a through hole 11, and the air extraction assembly 2 is installed at the through hole 11. The plastic bag 1 can adopt high-temperature-resistant plastic film to form through heat-pressing edge sealing.

[0042] refer to figure 2 , The air extraction assembly 2 includes an outer connector 21 and an inner connector 22, and the outer connector 21 and the inner connector 22 can be made of aluminum alloy. An air guide tube 211 is fixed on the outer connector 21 along its axis, and the two ends of the air guide tube 211 protrude from the main body of the outer connector 21 . The outer diameter of the air duct 211 is equal to or slightly smaller tha...

Embodiment 2

[0052] Embodiment two: a kind of preparation method of laminated glass, comprises the following steps:

[0053] S1: Lay the plastic film flat on the workbench and fold it in half, then place two glass plates 31 of the same size and a piece of film 32 between the plastic films, the edge of the plastic film is about 5-10 cm longer than the glass plate 31;

[0054] S2: Open a hole 11 in the middle of one side of the plastic film, install the air extraction component 2 at the through hole 11, and then use a hot-press edge sealing machine to seal the open sides of the plastic film on three sides to form a plastic bag 1, and the air extraction component 2 passes through Connect the trachea to the external vacuum pump for 10-30min;

[0055] S3: Transfer the plastic bag 1 together with the glass plate 31 and the film 32 inside the reaction kettle, the temperature in the reaction kettle is raised to 130°C, the temperature deviation does not exceed ±5°C, and the pressure is increased to...

Embodiment 3

[0057] Embodiment 3: A preparation method of angled glass, changing step S1 in Embodiment 2 to use three glass plates 31 and two films 32 alternately stacked between plastic films.

Abstract

The invention discloses an air pumping device and a preparation method of laminated glass. The technical scheme is characterized in that the air pumping device comprises a plastic bag, wherein at least one side of the plastic bag is open, a through hole is formed in one surface of the plastic bag, and an air pumping assembly communicated with the inner side and the outer side of the plastic bag isfixed at the through hole; at least two prefabricated glass plates and one film are aligned, laminated and placed in the plastic bag of the air pumping device, and the open edge of the plastic bag issealed; S2, vacuum pumping is performed on the glass plates and the film by the air pumping device for 10-30 min; S3, the air pumping device and glass plates and the film which are placed in the airpumping device are pressurized to 1.2-1.3 MPa at 120-130 DEG C for 30-90 min; S4, the glass plates and the film are discharged out of a furnace after being cooled and pressurized to the normal temperature and normal pressure state, the plastic bag of the air pumping device is taken down, and a finished laminated glass product is obtained. The problem that bubbles are produced easily in existing laminated glass production is solved.

Description

technical field [0001] The invention relates to the technical field of glass processing, more specifically, it relates to an air extraction device and a method for preparing laminated glass. Background technique [0002] Laminated glass is made of two or more pieces of glass sandwiched between one or more layers of organic polymer interlayer film. After special high-temperature pre-pressing or vacuuming and high-temperature and high-pressure treatment, the glass and the interlayer film are permanently bonded. An integrated composite glass product. Because of its characteristic that even if the glass breaks, the fragments will be stuck to the film, which can effectively prevent the occurrence of fragments piercing and falling, and ensure personal safety. Therefore, laminated glass is now used as a safety glass in buildings. Used a lot. [0003] For the prior art, please refer to the Chinese invention patent with the publication number CN105502972A, which discloses a prepara...
