Problems solved by technology

[0004] The current PVB interlayer film still has the disadvantage of low strength. When it is used as an interlayer film for laminated glass, when the laminated glass is broken, the PVB interlayer film will have a good adhesion to the glass fragments, thereby preventing the fragments from falling off randomly. However, when the laminated glass with a large area is broken, due to the relatively low strength of the PVB interlayer film, it cannot

Embodiment 1

[0031] Prepare raw materials by the following parts by weight:

[0032] 0.3 part of antioxidant;

[0033] 15 parts of sodium acrylate;

[0034] 0.10 part of ultraviolet absorber;

[0035] 4 parts polyethylene;

[0036] 85 parts of ethylene;

[0037] The preparation method is as follows: the raw materials are added into the mixer according to the weight and mixed evenly, and then kneaded in the extruder, the temperature of the extruder is controlled at 130-140°C, and the obtained extrudate is cast and calendered to form a film. Shaping is carried out through cooling and pulling, and finally through the winding process to obtain the interlayer film for laminated glass.

[0038] The intermediate film prepared by the embodiment is compared with the commercially available traditional intermediate film, and the results are as follows:

[0039]

Embodiment 2

[0041] Prepare raw materials by the following parts by weight:

Abstract

The invention discloses intermediate film for laminated glass. The intermediate film is characterized by being prepared from, by weight, 0.2-0.4 part of antioxidant, 10-18 parts of sodium acrylate, 3-5 parts of polyethylene and 80-90 parts of ethylene. The invention further discloses the laminated glass containing the intermediate film. Compared with the prior art, when applied to the laminated glass, the intermediate film for the laminated glass has the advantages of high glass strength, less deformation under stress, excellent transparency, a perfect real effect and good bonding performance.

Description

technical field [0001] The invention relates to the field of laminated glass, in particular to an interlayer film for laminated glass and laminated glass containing the same. Background technique [0002] Glass has been widely used in various fields such as buildings, vehicles and display devices because of its transparency, air-tightness, high strength and high hardness. In order to improve the use safety and applicability of large-area glass sheets, a layer of polyvinyl butyral (PVB) is glued between two glass sheets in the prior art laminated glass to make various safety glasses and windshields. . [0003] Polyvinyl butyral (PVB) is a condensation product of polyvinyl alcohol and butyraldehyde. The main application field of PVB in China is as an interlayer film and used in laminated glass. PVB interlayer film is a kind of polymer material formed by polyvinyl butyral resin plasticized and extruded by plasticizer. It not only looks like a translucent film, but also has no...
