摘 要: BOPP印刷膜易溶剂残留与BOPP薄膜的亚微观结构有关。本文从溶剂在薄膜中吸附-扩散与聚合物微观结构的关系、纳米有机改性蒙脱土对聚合物结晶性能、溶度参数和拉伸强度和透明性等方面的影响进行了综述,结果表明采用纳米有机改性蒙脱土可以增加BOPP的结晶度、提高BOPP的溶度参数,并能提高BOPP薄膜的拉伸性和透明性,为研制低溶剂残留的BOPP提供了改性依据。 Residual solvent in BOPP printing film is related to its submicroscopic structure. The relationship betweensolvent adsorption-diffusion and polymer microstructure, the effect of nano organic modified montmorillonite (OMMT) onpolymer crystallization properties, solubility parameters, tensile strength and transparency were reviewed. The resultsshowed that OMMT could increase the crystallinity, solubility parameters, extensibility and transparency of BOPP film,which could provide the basis for the development of BOPP with low residual solvent.
