| 摘 要： | 采用预乳化及种子乳液聚合方法制备了纳米二氧化钛/丙烯酸酯复合乳液,研究了丙烯酸(AA)、过硫酸钾(KPS)、乳化剂及纳米二氧化钛用量对聚合反应稳定性的影响,并采用红外光谱对复合乳胶膜的结构进行了表征。结果表明:当AA、KPS、乳化剂和纳米二氧化钛的用量分别为3.0%,0.5%,3.3%和2.0%时,体系中的凝胶较少,具有良好的聚合反应稳定性。 |

| Abstract: | Nano-titanium dioxide(TiO2)/acrylate composite emulsions were synthesized by pre-emulsification technology and seed emulsion polymerization method.The effect of the amount of acrylic acid(AA),potassium persulfate(KPS),emulsifier and nano-TiO2 on the polymerization reaction stability was studied,and the structure of the composite latex film was characterized.The results showed that when the amount of AA,KPS,emulsifier and nano-TiO2 were 3.0%,0.5%,3.3% and 2.0%,respectively,the gel in the reaction system was little and the polymerization reaction stability was good. |
| Keywords: | nano-titanium dioxide acrylate composite emulsion reaction stability |
