主要介绍了改性水溶性聚氨酯胶黏剂应具备的特点,影响其使用性能的因素,对其性能的改进方法等做了一些阐述,结合实际工作经验得出以下结论:发展改性水溶性胶黏剂的最终目的,是取代目前正在大量使用的高污染的双组分溶剂型聚氨酯胶黏剂,也是水溶性聚氨酯的主要发展方向。良好的具有应用价值的水溶性聚氨酯胶黏剂体系必须同时具备3个基本要素:(1)具有符合不同应用需求的各项性能;(2)具有良好干燥成膜及涂敷加工性能;(3)优良的水中稳定性。
Mainly introduces the characteristics of modified water-soluble polyurethane adhesive, the factors that affect its performance, some of its performance improvement methods are described, combined with the actual work experience to draw the following conclusions: The development of modified water-soluble glue The ultimate goal of adhesive is to replace the currently heavily used two-component solvent-borne polyurethane adhesive, which is also the main development direction of water-soluble polyurethane. Good application value of the water-soluble polyurethane adhesive system must have three basic elements: (1) has to meet the different application requirements of the performance; (2) has a good drying film and coating processing performance; (3 Excellent water stability.
