According to the interlayer film for the laminated glass, the processing method of the interlayer film, the laminated glass and the processing method of the laminated glass, the thickness of the weakening area of the interlayer film is smaller than that of the main body area through stretching and thinning, tight attachment of the inner-layer glass, the outer-layer glass and the interlayer film is guaranteed through staged lamination process control, and the laminated glass with the smaller HIC value is obtained; when being used for a front windshield, the anti-collision device can effectively reduce the injury to pedestrians; and the processing technology is simple, low in cost and suitable for large-scale automatic production.
本发明提出了夹层玻璃用中间膜及其加工方法、夹层玻璃及其加工方法,通过拉伸减薄使得中间膜的弱化区域的厚度小于主体区域的厚度,并通过分阶段的合片工艺控制,保证了内外层玻璃与中间膜的紧密贴合,得到HIC值更小的夹层玻璃,当将其用于前挡风玻璃时,能够有效地降低对行人的伤害;且加工工艺简单,成本低,适于大规模自动化生产。
