压敏胶粘剂,简称压敏胶,是丙烯酸系和橡胶系的溶剂型或胶乳型胶粘剂,主要用于生产压敏胶带。
 
近年来,由于高速操作、合理涂布、排除溶剂公害问题的需要,发展了热熔压敏胶。热熔压敏胶(HMPSA)是以热塑性聚合物为主的胶粘剂,集热熔胶和压敏胶的特点于一体,无溶剂,无污染,使用比较方便。它在熔融状态下进行涂抹,冷却固化后施加轻度指压就能起到粘合作用。因为它的强大作用,所以广泛应用于尿布、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、壁纸及制鞋等方面。
热塑性弹性体压敏胶是由SBS、SIS、增粘树脂、软化剂、防老剂、着色剂等组成,只有各组分配合适当,才能制得性能优异的压敏胶。
Pressure sensitive adhesive, referred to as pressure sensitive adhesive, is a solvent or latex adhesive of acrylic and rubber series, which is mainly used to produce pressure sensitive adhesive tape.
In recent years, due to the need of high-speed operation, reasonable coating and elimination of solvent pollution, hot-melt pressure-sensitive adhesive has been developed. Hot melt pressure sensitive adhesive (HMPSA) is a kind of adhesive based on thermoplastic polymer. It integrates the characteristics of hot melt adhesive and pressure sensitive adhesive. It is solvent-free, pollution-free and easy to use. It is applied in the molten state, after cooling and curing, a light finger pressure can play a bonding role. Because of its powerful function, it is widely used in diapers, women's products, double-sided tape, labels, packaging, medical and health care, book binding, surface protective film, wood processing, wallpaper and shoemaking.
Thermoplastic elastomer pressure-sensitive adhesive is composed of SBS, SIS, tackifying resin, softener, antioxidant, colorant, etc. only when each group is properly distributed, can excellent pressure-sensitive adhesive be produced.
