| 摘 要： | 用种子乳液聚合法,以OP-10作为乳化剂,以K2S2O8 作为引发剂,以丙烯酸 (AA)为单体接枝改性石蜡(PF)乳液,合成了石蜡丙烯酸(PFAA)复合乳液。实验采用单体滴加工艺,以乳液稳定性作为评价指标,选择引发剂用量、单体用量、反应温度和反应时间为考察因素,利用正交实验L9 (34 )筛选出最佳合成工艺条件为:反应温度 70~75℃,反应时间 2h,引发剂用量w(K2S2O8 ) =0 16% ~0 20%,单体用量w(AA) =16 5% ~18 0%。红外光谱显示AA单体已引入到共聚物大分子中,扫描电镜揭示PFAA复合乳液的表面性状发生了改变。

| Abstract: | With nonionic OP-10 as emulsifier,potassium persulfate (K_2S_2O_8) as initiator,acrylic acid(AA) modified paraffine(PF) hybrid emulsion was synthesized by seed emulsion polymerization.With the stability of the emulsion as assessment indices,the optimum process conditions for preparing paraffine-acrylic acid (PFAA) hybrid emulsion were determined by orthogonal design method as follows.Reaction temperature was 70~75 ℃,reaction time was 2 h,amounts of initiator and monomer were w(K_2S_2O_8)=0.16%～0.20% and w(AA)=16.5%～18.0%.FTIR analysis indicates that in the macromolecules PF is copolymerized with AA monomers thoroughly.SEM photographs illustrate that the surface properties of PFAA hybrid emulsion are efficiently improved. |
