摘要: 采用含氟丙烯酸酯、甲基丙烯酸甘油酯、N,N-二甲基甲酰胺、丙烯酸丁酯、一缩二丙二醇为单体,以NP-10、NP-8、十八烷基三甲基氯化铵为乳化剂,偶氮二异丁脒盐酸盐作为引发剂,使用微射流纳米分散仪预乳化法制备拒水拒油含氟丙烯酸酯乳液,并研究了预乳化工艺对乳液粒径及其应用性能的影响。结果表明,在103.425MPa压力下微射流预乳化2次得到整理剂的粒径均匀分布在50~57nm之间,整理剂带正电荷,物化性能稳定。用其整理后的棉织物,对水和对油接触角分别达到140°和125°以上。

Abstract: A kind of acrylate polymer emulsion being provided with water and oil repellent properties was synthesized by emulsion polymerization, in which the fluorinated acrylate together with glycidyl methacrylat, N,N-dimethyl formamide, butyl acrylate and dipropylene glycol was selected as monomers, and NP-10, NP-8 and octadecyl trimethyl ammonium chloride were employed as emulsifying agent, and 2,2’-azoisobutyramidinedihydrochloride was taken as the initiator in this article. The effects of pre-emulsifying technology on the emulsion particle size and application were discussed, and the structure was featured by IR. The results demonstrated that the emulsion particle size distributed in 50~57nm and the emulsion particle was positive electricity after being pre-emulsificated twice under the pressure of 15000psi by micro-jet dispersion method. And the performance was stable. Therefore, the water and oil repellent properties of the cotton fabrics treated with the emulsion was excellent, and the contact angle to water and oil were over 140o and 145o respectively.

Key words: micro-jet method, pre-emulsifying, emulsion polymerization, contact angle, fabric
