高固含量丙烯酸酯微乳液的研究

以甲基丙烯酸甲酯(MMA)为硬单体、丙烯酸丁酯(BA)为软单体、丙烯酸(AA)和N-羟甲基丙烯酰胺(NMA)为功能性单体以及过硫酸铵(APS)-亚硫酸氢钠为引发剂,合成了固含量为45%左右的丙烯酸酯微乳液。研究结果表明:普通乳化剂烷基酚醚磺基琥珀酸酯钠盐(OS)、十二烷基硫酸钠(SDS)]、反应性乳化剂烯丙氧基羟丙磺酸钠(HAPS)]、NMA和反应温度等对合成的丙烯酸酯微乳液性能有影响;当反应温度为80～85℃、w(OS)=4.2%、w(SDS)=2.2%、w(HAPS)=0.5%和w(NMA)=0.50%时,合成的丙烯酸酯微乳液的综合性能较好。

Study on acrylate micro-emulsion with high solid content

With methyl methacrylate(MMA) as hard monomer,butyl acrylate(BA) as soft monomer,acrylic acid(AA) and N-hydroxymethyl acrylamide(NMA) as functional monomers,and ammonium persulfate(APS)-sodium bisulfite as initiator,so an acrylate micro-emulsion with 45% about solid content was synthetized.The research results showed that the some factors,including ordinary emulsifier(OS and SDS),reactive emulsifier(HAPS),NMA and reaction temperature,have influence on performances of acrylate micro-emulsion.The combination ...
