Problems solved by technology

The second is to pour the prepared adhesive slurry into the middle of two or more pieces of glass that have been closed, and make laminated glass through heating polymerization or light polymerization, which is called "grouting method" or "wet method". There are many shortcomings in the products of the grouting production process, and they are less used
[0004] The flat glass used by traditional SGP is mostly ordinary ultra-clear or white glass products, and the transmittance will be significantly reduced after adding film, about 7%.

Embodiment 1

[0045] Including the upper layer of ultra-clear coated glass layer, film layer and lower layer of ultra-clear coated glass arranged in sequence from top to bottom; the thickness of the film layer is 0.76mm or 1.14mm or 1.52mm or 1.9mm; the upper layer of ultra-clear coated glass layer Or the thickness of the lower layer of ultra-clear coated glass is 0.6-6 mm, and the film in the film layer is an SGP film. The upper layer of ultra-white coated glass and the lower layer of ultra-white coated glass are tempered glass with a thickness of 0.6-0.9mm, and the thickness of the film layer is 1.9mm.

[0046] The process for preparing laminated glass includes the following process steps:

[0047] S1: Cut the original glass sheet with a thickness of 6mm into the set size and use a glass edger to edge it;

[0048] S2: Clean the glass treated in step S1 and dry it, then place the glass in a drying room until the glass reaches room temperature;

[0049] S3: Put the glass treated in step S2 ...

Embodiment 2

[0055] The difference from Embodiment 1 is that, as figure 1 As shown, the laminated glass includes an upper transparent material layer, a film layer and a lower transparent material layer arranged sequentially from top to bottom; the thickness of the film layer is 0.76mm or 1.14mm or 1.52mm or 1.9mm; the upper layer is transparent The thickness of the material layer or the lower transparent material layer is 0.6-6mm, the film in the film layer is polycarbonate film, and the material used in the upper transparent material layer or the lower transparent material layer is anti-reflection glass or ultra-thin float glass or Semi-tempered glass or plexiglass. The material used for the upper transparent material layer 1 or the lower transparent material layer 2 is anti-reflection glass or ultra-thin float glass or semi-tempered glass, and glass fibers 3 crossed vertically and vertically are arranged in the upper transparent material layer 1 or the lower transparent material layer 2 ...

Embodiment 3

[0057] The difference from Example 1 is that the process for preparing laminated glass includes the following process steps:

[0058] S1: Laminated glass is made from molten glass raw materials and polycarbonate film using a float glass preparation process; the glass raw materials include SiO2, Al2O3, K2O, Na2O, CaO and MgO, SiO2 is 72.8 to 73.9 parts by weight, and Al2O3 is 0.7-0.9 parts by weight, 0.1-0.3 parts by weight of K2O, 13-14 parts by weight of Na2O, 7.7-9.8 parts by weight of CaO, and 3.3-3.8 parts by weight of MgO. The molten liquid is melted at high temperature in the French glass melting furnace. The molten liquid flows into the working pool after being clarified and homogenized. The molten liquid enters the forming tin tank from the launder in the working pool to form a strip-shaped continuous glass plate. Cut into finished products; the melting temperature in the float glass melting furnace is 1220-1295°C, the clarification and homogenization temperature is 15...

Abstract

The invention discloses laminated glass, comprising an upper super-white coated glass layer, SGP (SentryGlas Plus) film and a lower super-white coated glass layer. The invention also discloses a preparation method of the laminated glass, comprising the steps of providing a raw sheet, cutting, polishing edge, washing, tempering, coating, washing, laminating, pressing primarily, vacuumizing, heatingand pressurizing in a high-pressure kettle, holding the temperature and pressure in the high-pressure kettle, lowering the temperature and pressure in the high-pressure kettle, removing from the kettle, trimming and dressing, finishing, packaging, and allowing the finished glass to leave a factory. The heating mode is modified to a mode with a heating tube and a convection fan, so that heating uniformity of glass is improved, glass heating efficiency is improved, SGP laminated glass has better visible light transmittance and strength, production time of the SGP laminated glass is shortened, and energy consumption is lowered.

Description

technical field [0001] The invention relates to laminated glass and its preparation process. Background technique [0002] Laminated glass is made of two or more pieces of glass with one or more layers of organic polymer intermediate film between them. Composite glass products that are permanently bonded together. [0003] There are two main production methods of laminated glass: one is to sandwich polyvinyl butyral (PVB) film between two or more layers of glass, and put it into an autoclave for hot pressing, which is called "film hot pressing method". " or "dry method", suitable for industrial production. The second is to pour the prepared adhesive slurry into the middle of two or more pieces of glass that have been closed, and make laminated glass through heating polymerization or light polymerization, which is called "grouting method" or "wet method". The products of the grouting production process have many shortcomings and are used less. Commonly used laminated glas...
