2.
Effect of chain extenders on PVB resin and film was studied The addition of chain extender in synthesis of PVB resin was 3% of the volume of butyl aldehyde and in processing of the film no more than 3% of the quality of PVB resin, thus the Mw of PVB resin was increased, adhesion of PVB film to glass decreased, and tensile strength of PVB film raised greatly.
实验证明,合成树脂时加入相对于正丁醛体积3%左右的扩链剂1;加工成膜时,加入相对于PVB树脂质量3%以下的扩链剂2,可明显提高PVB的分子量,降低PVB薄膜与玻璃的粘结性能,所得薄膜的拉伸强度可明显提高,而且制得的夹层安全玻璃的耐冲击性能没有受到影响。
