中文摘要:
      采用流延成膜工艺制备了CCMC/PVA共混复合膜,研究了戊二醛交联剂对复合膜的透光性能和力学性能的影响。结果表明:交联处理膜的致密性和机械性能显著提高;当戊二醛添加量为2%(质量分数),体系的pH为10,交联反应温度为85 ℃,交联时间为35 min时,复合膜的拉伸强度可达18.91 MPa,断裂伸长率为226%,透光率为75%。
英文摘要:
      CCMC/PVA blend film was prepared by solution mixing method. The effect of glutaric dialdehyde crosslinking agent on the hydrolytic resistance, light transmission and mechanical property of CCMC/ PVA complex film were studied. The results showed that the compactness, water resisting property and mechanical property of CCMC/PVA blend film increased remarkably by crosslinking treatment. The tensile strength was 18.91 MPa, elongation at break was 226%, luminousness was 75% when the amount of glutaric dialdehyde was 2%, pH was 10, crosslinking reaction temperature was 85 ℃, and reaction time was 35 min respectively.
