为什么液体AMPS 使用越来越广泛,下面就由小编来为您讲解一下

2-丙烯酰胺基-2-甲基丙磺酸钠(AMPS-NA)是50%的钠盐液，主要应用于乳液、水性粘合剂及密封胶。在乳液中添加2-丙烯酰胺基-2-甲基丙磺酸钠与丙烯酸、苯乙烯、或醋酸乙烯酯反应，引进反应性的乳化剂，防止乳化剂的迁移。仅用2-3%的2-丙烯酰胺基-2-甲基丙磺酸钠，就可以使乳液具有低粘度和显著的稳定性。同时不需要加入如乙二醇等添加剂，并能提高漆膜的附着力、热稳定性及抗静电性，提高乳胶漆的抗水性及耐擦洗性。 AMPS钠盐中丙烯酰胺基团会使聚合反应加快；两个侧甲基和甲基磺酸钠结合在氨基后面，可以阻止其水解和热降解；磺化基团可以使单体在任何PH的情况下都能表现出较高的亲水性和离子特征。通过对AMPS钠盐合成乳液时所产生的凝胶、颗粒、表面电荷密度、胶乳稳定性等方面经过详细研究后得出结论：由于高聚物具有高分子电解质特性，吸附在胶乳粒子表面行程了电离层，从而增加了胶乳的稳定性。使用AMPS钠盐，不但可以代替羧酸单体，还能减少其他表面活性剂的使用量，具有良好的抗水界性和热稳定性；由这些乳液制成的产品具有光滑和柔韧、舒适性的触感，制成的涂料的耐擦洗性亦有显著的改善。所以AMPS钠盐是一种高反应性，高度亲水性的功能性聚合单体，也是一种可聚合性表面活性剂。

Why are liquid amps used more and more widely

Sodium 2-acrylamide-2-methylpropanesulfonate (amps-na) is a 50% sodium salt solution, which is mainly used in lotion, water-based adhesives and sealants. Add sodium 2-acrylamide-2-methylpropanesulfonate to the lotion to react with acrylic acid, styrene or vinyl acetate, and introduce reactive emulsifiers to prevent the migration of emulsifiers. Only 2-3% sodium 2-acrylamide-2-methylpropanesulfonate can make the lotion have low viscosity and significant stability. At the same time, there is no need to add additives such as ethylene glycol, which can improve the adhesion, thermal stability and antistatic of the paint film, and improve the water resistance and scrub resistance of the emulsion paint. Acrylamide group in amps sodium salt will accelerate the polymerization reaction; The two side methyl groups and sodium methanesulfonate are combined behind the amino group, which can prevent its hydrolysis and thermal degradation; Sulfonated groups can make monomers show high hydrophilicity and ionic characteristics at any pH. After a detailed study on the gel, particles, surface charge density, latex stability and other aspects produced during the synthesis of lotion with AMPS sodium salt, it is concluded that because the polymer has the characteristics of polymer electrolyte, it travels through the ionosphere on the surface of latex particles, thus increasing the stability of latex. The use of AMPS sodium salt can not only replace the carboxylic acid monomer, but also reduce the use of other surfactants, and has good water resistance and thermal stability; The products made of these lotion have smooth, flexible and comfortable touch, and the scrub resistance of the coatings made has also been significantly improved. Therefore, amps sodium salt is a highly reactive, highly hydrophilic functional polymeric monomer and a polymerizable surfactant.
