摘要
简要介绍了无溶剂复合工艺在国内外的发展过程。针对异氰酸酯种类、小分子扩链剂及NCO/OH的比例等因素对软包装用双组分无溶剂聚氨酯胶粘剂复合薄膜材料的剥离强度、胶粘剂本身硬度及固化速度的影响进行了初步探讨。
The Paper reviews the development process of solventless laminating technology at home and abroad. Moreover, it makes a brief study on the influence of isocyanate, micromoleeular chain extendor, the redio of NCO/OH and so on to the peel strength of laminating material, the hardnesS of this adhesive and the cure rate.
