含氟乳化剂FC80含量对丙烯酸酯乳液共聚物性能的影响

Effects of FC80 Fluorine Emulsifier Content on Propertes of Acrylate Copolymer Emulsions

研究了含氟乳化剂 FC80含量对丙酸酯乳液共聚物性能的影响。结果表明随 FC80含量从0 .0 1 %增加到 0 .3% ,丙烯酸酯乳液共聚物的表面张力和粘度下降 ;耐酸性增强 ,p H值稳定范围增宽 ;乳液粒子直径下降 ;稀释和贮存稳定性好 ;耐电解质稳定性呈现抛物线变化。 FC80含氟乳化剂的最佳用量以 0 .0 5 %到 0 .1 %为宜。

This paper has investigated the effects of fluorine- containing emulsifier FC80 content on the properties of acrylate copolymer emulsions.The experimental results show thatwith increasing of FC80 content from0 .0 1 % to0 .3 % ,the surface tension and viscosity of the emulsions decrease;the acid- resistance increases;the particle size decreases;and the electrolyte stability is improved.The suitable FC80 content is in the range of0 .0 5 % to0 .1 % .
