透明亲水丙烯酸树脂防雾材料的制备及研究

通过溶液聚合的方法制备了防雾材料亲水丙烯酸树脂。通过试验比较,得到了最佳工艺条件,软单体为丙烯酸乙酯,硬单体为甲基丙烯酸甲酯,官能单体则以丙烯酸、甲基丙烯酸为最佳,辅助官能单体为甲基丙烯酸β-羟乙酯。交联体系采用自交联体系,交联剂采用含有亲水氨基的N-羟甲基丙烯酰胺,交联剂与羧酸质量比为4∶1;交联固化温度100℃,固化时间40 min。由此制备的防雾树脂具有优良的水溶性和防雾性。

Research on Preparation of Transparent Hydrophilic Antifogging Acrylate Resin

Solution polymerization method was used to prepare hydrophilic anti-fogging acrylate resin.By means of comparison,the optimum synthesis technology conditions was obtained that take ethyl acrylate as soft monomer,methylcrylate was used as hard monomer.The best functional monomers were acrylic acid and ethyl acrylic acid,the accessory functional monomer was β-hydroxyl ethyl acrylate.Cross-linking agent methylol acrylamide belongs to self-cross-linking system.Cross linker was N-hydroxymethyl acrylamide.The quality rate of cross-linking agent and carboxylic acid is 4 to 1.The resin can be cured perfectly at the temperature of 100 ℃ for 40 min.The prepared acrylate resin had excellent water-solubility and anti-fogging character.
