热熔压敏胶的合成与性能研究 摘 要 热熔压敏胶是以热塑性聚合物为主的胶黏剂，它兼有热熔和压敏双重特性，涂胶时必须将胶加热熔化（一般为150―200℃），在熔融状态下进行涂抹，冷却中固化，固化后施加轻度指压就能起到粘接作用。它的应用范围很广，目前已用于尿布、妇女用品、双面胶带、标签、包装、医疗卫生、书籍装订、表面保护膜、木材加工、壁纸及制鞋、标签纸及地毯粘接等方面，也可制作纸基或布基的胶黏带，其中，包装用HMPSA消费量最大，几乎占总量的一半，是无溶剂型压敏胶黏剂中发展较快的几个品种之一。 本文针对热熔压敏胶的初黏力、持黏力、剥离强度三大压敏性能进行研究，目的是设计研究出一种具有一定初黏力，一定剥离强度，较强持黏力的热熔压敏胶，在这个基础上，最好能具有耐高温性能。 关键词：热熔胶 压敏胶 持粘力 软化点 剥离强度 Synthesis and properties of hot melt pressure-sensitive adhesive research Abstract Hot melt pressure-sensitive adhesive is a thermoplastic polymer-based adhesive. It has both hot melt and pressure-sensitive double feature. it must be heated to melt when gluing (typically 150-200 ℃).To smear over in the molten state，Cooling in the solidification, Light finger pressure applied after curing can play a role of adhesive .It is widely used in many area, such as it has been used in diapers, womens products, double-sided adhesive tape, labels, packaging, health, book binding, surface protection film, wood processing, wallpaper and footwear, and carpet adhesive label paper , and so on. It can also be made of paper-based or cloth adhesive tape. Of which the largest consumer packaging is hot melt pressure-sensitive adhesive, accounting for almost half of the total. Pressure-sensitive adhesive is solvent-free hot melt pressure-sensitive adhesive rapid development one of several species In this article, I research for the beginning Adhesion, holding adhesion and the peel strength of the hot melt pressure-sensitive adhesive (HMPSA). My objective is to design developed a new HMPSA. It has the beginning Adhesion, the holding adhesion and a strongly peel strength. On this basis, it is better to have good high temperature resistant performance.
