摘　　要：以有机氟﹑有机硅以及(甲基)丙烯酸酯为原料,采用溶液聚合的方法制备了氟硅树脂防水剂,探讨了软硬单体配比、反应温度和单体投入方式对防水剂性能的影响,确定了工艺参数。研究了此防水剂对石膏试样耐水性能的影响。试验结果表明:该氟硅树脂石膏防水剂对石膏试样的短期防水性能具有显著改善,但长期使用时,防水性能有一定程度的削弱。Organic fluorine,organic silicon,and（methyl） acrylate are used to prepare a water-proofing gypsum additive which is a fluorosilicon resin by liquor polymerization method.Effects of soft hard monomer ratio,reaction temperature and the introducing model of monomers on the properties of the waterproofing additive are discussed,and the process parameters are determined.Experiment shows that the early waterproofing performance of gypsum samples with the additive is significantly improved,but the water resistance is weakened to a certain extent for a long time.
