【摘要】 利用溶胶凝胶法制备的亲水性丙烯酸共聚合树脂形成的亲水防雾膜具有玻璃表面防雾功效。研究了材料成分和制备工艺对该玻璃防雾膜性能的影响。结果表明,丙烯酸含量越高,树脂水溶性越好,固化膜的防雾性能越好,而耐水性下降。改变丙烯酸与甲基丙烯酸的配比对防雾膜性能也有影响,在适当范围内增加甲基丙烯酸量有助于提高共聚反应速度转化率及丙烯酸防雾树脂的亲水防雾性。同时采用所有单体半连续滴加和单取丙烯酸β-羟乙酯和丙烯酸滴加的方式,得到的产物分子组成较为均匀,性能也比较稳定。更多还原

【Abstract】 The effects of the acrylic anti-fogging film composition and process parameters on the anti-fogging properties were investigated.The results show that the higher the content of acrylic acid,the better the solubility of resin into water,as well as the anti-fogging property.But water resistance decreased slightly.The property of anti-fogging film was also affected by the variation of acrylic to methacrylate ratio.The methacrylate can promote copolymerization conversion speed and improve anti-fogging property of anti-fogging acrylic resin in a certain range.The homogeneous product molecules and the stable properties are achieved through a semi continuing monomer feeding method,with simultaneous addition of β-hydroxyethyl acrylate and acrylic acid.更多还原
