| 摘 要： | 由于有机硅的低表面能和硅氧烷的长链大分子结构,难以被乳化剂乳化而进入胶束,有机硅和丙烯酸单体的共聚受到很大限制,因此以丙烯酸酯、乙烯基硅油为主要原料,以OP-10和十二烷基硫酸钠(SDS)为复合乳化剂,采用连续滴加法,制备了有机硅改性丙烯酸酯乳液(硅丙乳液).论述了聚合工艺,利用红外光谱和激光粒度分析仪等方法对乳液及其涂膜的性能进行了分析与表征.结果表明,这种合成工艺简便、经济、产率高;乳液尺寸分布窄,各项性能优异;其涂层无色透明、附着力好,并有较强的耐水性(吸水性4.8%).

| Abstract: | Polymerization of silicone and acrylic acid is restricted by the difficulty of being emulsified caused by low surface energy and long chain molecule structure of silicone and siloxane respectively.A polyacrylate emulsion modified by silicone(silicone-acrylate emulsion) is prepared with sodium dodecyl sulfate(SDS) and OP-10 as emulsifier,acrylate and ethylene silicone oils as raw materials by means of continuous dripping.The polymerization technology is studied.The properties of this emulsion and its film are analyzed by IR and laser granularity analyzer.The results show that this synthesis technology is simple,economical and high yield.The emulsion has excellent properties and it is dimensional uniformity.And the emulsion film is transparent,good adhesion,and high water resistance(water absorption rate is 4.8%). |
