与防水剂共浴硬挺剂的制备

摘要：以苯乙烯(St)、丙烯酸丁酯(BA)、甲基丙烯酸甲酯(MMA)、甲基丙烯酸羟乙酯(HEMA)、丙烯酸十八酯为(ODA)主要原料，以阳、非复合表面活性剂十八烷基二甲基氯化铵和异构醇醚1370为乳化剂，以2-2’偶氮二异丁基脒二盐酸盐为引化剂，采用种子乳液聚合的方法合成了核壳型阳离子型乳液。其制备的最佳工艺条件：阳、非复合表面活性剂配比2:1、引发剂用量为1%、ODA用量为2.5%、反应温度82℃、反应时间8小时。利用电位仪分析表征自制乳液的电荷量大小。对其与防水剂共浴应用性能进行评价，评价结果表明，该乳液有很好的稳定性，同时与防水剂具有良好的相容性，而且具有很好的硬挺效果。

Preparation of Stiffening Agent Common-bathing with Waterproofing Agent

Abstract: The Stiffening agent was prepared by using Styrene (St), butyl acrylate (BA), methyl methacrylate (MMA), hydroxyethyl methacrylate (HEMA), octadecyl acrylate (ODA) as the main raw material, with positive and negative complex surface activity Octadecyldimethylammonium chloride and isomeric alcohol ether 1370 as emulsifiers, 2-2' azobisisobutyramidine dihydrochloride as the priming agent by seed pore liquid polymerization.Optimum process conditions: 2:1 ratio of cationic surfactant and non-surfactant surfactant 1% Octadecyl acrylate 2.8% stearyl ester, Reaction time 8 hours and 82°C reaction temperature. A potentiometer was used to characterize the amount of charge in the self-made emulsion. After analyzing and evaluating the performance of the co-bath with the water repellent, the experimental results show that the emulsion has good stability, has good compatibility with the water repellent, and has a very good stiffening effect at the same time.

1.1 硬挺剂介绍

硬挺剂的分子量很大，其胶粒的聚合度比较高，具有广泛的应用价值，硬挺剂不仅仅可以改善织物的手感，还能够使织物具有耐摩擦的效果，有些种类的硬挺剂还可改善提高纺织产物的弹性，硬挺剂的种类比较多，大概可以分为五类：市场上一些比较常见硬挺剂性能对比：与防水剂共浴硬挺剂的制备:http://www.chuibin.com/huaxue/lunwen_205413.html
