水分散型聚氨酯胶膜拉伸强度的影响因素研究

Study of the Affecting Factors of the Tensile Strength of Water-based Polyurethane

在合成性能优异的水分散型聚氨酯的基础上,系统地研究了初聚NCO/OH、聚酯多元醇分子量、聚酯类型、TMP％、扩链剂种类和用量、COOH％对胶膜拉伸强度的影响。

The affecting factors of the tensile strength of water-based polyurethane such as the initial NCO/OH (mol/mol), the molecular weight and style of polyester, TMP%, style and amount of the chain-extender and COOH% were studied in details.
