摘　　要：采用反应型阳离子乳化剂,通过化学改性法制备功能化硅基改性丙烯酸酯无氟防水剂,并研究其和阴离子丙烯酸胶乳复配使用,用作施胶剂探究其对玻纤滤纸性能的影响。研究表明,在阴离子丙烯酸树脂(α、β胶乳)中添加10%硅基改性丙烯酸酯无氟防水剂,施胶后的滤纸在强度、过滤性能和防水性能等方面获得优异的性能,且采用该化学品组合生产的滤纸PF值、耐湿性和纵向强度分别达到12.5、1150mmH2O和1.62kN/m。Functional silicon-based modified acrylate fluoride-free waterproofing agent was prepared by chemical modification method using reactive cationic emulsifier.The compatibility of this emulsion was studied as a sizing agent to investigate its effect on the properties of fiberglass filter paper.The study showed that adding 10%silicon-based emulsion to anionic acrylic resin(α,β)results in excellent strength,filtration performance,and waterproofing performance of the filter paper after sizing.The glass fiber filter paper produced using this chemical combination has a PF value,moisture resistance,and machine strength of 12.5,1150 mmH2O,and 1.62kN/m,respectively.
