Example Embodiment

[0053] Embodiment 1: A production process of laminated glass, which is obtained through the following steps:

[0054] Step one: cutting, grinding and washing a large piece of glass raw material to obtain an original glass sheet;

[0055] Step 2: Combine the film: Put a layer of composite film between the two original glass sheets, and the ratio of the thickness of the original glass to the thickness of the composite film is 7.5:1, and cut and remove the excess composite film. To form a glass sheet;

[0056] Step three, heating and pressurizing: the glass composite obtained in step two is preheated and prepressed, the preheating temperature is 60℃, the preheating time is 15min; the prepressing pressure is 1.1MPa; the prepressing The time is 15 minutes; after the composite membrane is softened, it enters into the autoclave for hot-press forming to obtain laminated glass.

[0057] Among them, the components included in the composite membrane and their parts by weight are as shown in Tab...

Example Embodiment

[0064] Example 2-5: A production process of laminated glass. The difference from Example 1 is that the components included in the composite film and their weight parts are shown in Table 1.

Abstract

The invention discloses a production process of laminated glass and belongs to the technical field of glass. The process comprises the following steps: 1, cutting, abrasively cleaning and cleaning a massive glass raw material so as to obtain raw glass sheets; 2, putting a composite film into two layers or more layers of the raw glass sheets, cutting and removing excessive composite film part, andforming laminated glass; 3, preheating and pre-pressing on the laminated glass obtained in the step 2, softening the composite film, and performing hot press molding in an autoclave, thereby obtainingthe laminated glass. The composite film comprises PVB (Polyvinyl Butyral) resin, a plasticizer, trans-polyisoprene rubber-grafted methyl methacrylate copolymer. In the step 3, an operating temperature of hot press molding in the autoclave is 135-160 DEG C, the operating pressure is 1.3-1.6MPa, and the working time is 45-55 minutes. The composite film in the laminated glass disclosed by the invention has high bonding strength, so that the integrity of the laminated glass is excellent.

Description

technical field [0001] The invention relates to the technical field of glass, more specifically, it relates to a production process of laminated glass. Background technique [0002] Laminated glass is a composite glass product that sandwiches one or more layers of organic polymer interlayer film between two or more pieces of glass. After treatment, the glass and the interlayer film are bonded together. Commonly used laminated glass interlayers are: PVB, SGP, EVA, PU, ​​etc. [0003] However, in the prior art, there is a defect that the bonding strength is not good enough. Therefore, a laminated glass with a good bonding strength of the intermediate film has wide application value. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a production process for laminated glass, wherein the intermediate film (composite film in this application) in the laminated glass has the advantage of excellent b...
