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:
