一种环氧树脂乳化剂及其制备方法
摘要：
一种环氧树脂乳化剂，由单体丙烯酸或甲基丙烯酸、丙烯酸烷基酯或/和甲基丙烯酸烷基酯、苯乙烯、醋酸乙烯酯及丙烯酸缩水甘油酯或甲基丙烯酸缩水甘油酯聚合反应而成，具有水溶性，分子量为5000～20000。一种环氧树脂乳化剂的制备方法，各原料的质量百分数为：单体30～50％、溶剂49～69％、分子量调节剂0.015～0.2％、引发剂0.15～1.0％；将溶剂放入反应容器并加热，当溶剂被加热至75～90℃时，向反应容器中加入单体、分子量调节剂和引发剂混合物总质量的5～15％，并在搅拌下反应25～40分钟，然后在搅拌下将余下的单体、分子量调节剂和引发剂混合物滴入反应容器，于75～90℃继续反应1～3小时。
摘要（英）：

The invention relates to an epoxy resin emulsifying agent which is prepared from monomer acrylic acid or methacrylic acid, alkyl acrylate or/and methacrylate and alkyl methacrylate esters, vinyl benzene, vinyl acetate and glycidyl acrylate or glycidyl methacrylate by a polymerization reaction. The epoxy resin emulsifying agent has water solubility, and the molecular weight is 5000-20000. A preparation method of the epoxy resin emulsifying agent comprises the following steps: taking 30-50% of monomer, 49-69% of solvent, 0.015-0.2% of molecular weight regulator and 0.15-1.0% of initiator according to the mass percent of each raw material; putting the solvent into a reaction container, heating, adding 5-15% of the total mass of the mixture of the monomer, the monomer, the molecular weight regulator and the initiator into the reaction container when heating the solvent to 75-90 DEG C, reacting for 25-40 minutes under stirring, then dripping the rest of the mixture of the monomer, the molecular weight regulator and the initiator into the reaction container under stirring, and reacting for 1-3 hours continuously at the temperature of 75-90 DEG C.
