| 摘 要： | 以甲基丙烯酸甲酯(MMA)、苯乙烯(St)和丙烯酸丁酯(BA)等为主要单体,引入丙烯酸(AA)、丙烯酸羟基乙酯(HEA)与甲基丙烯酸异冰片酯(IBOMA)等作为功能单体,通过半连续溶液聚合工艺,最后加水分散制得水性羟基丙烯酸树脂。利用FT-IR、透光度、粘度分析研究了单体配比、引发剂(BPO)用量、温度、链转移剂(DDM)用量、功能单体用量等因素对树脂性能的影响。结果表明,当AA、HEA、IBOMA、BPO和DDM的质量分数分别为3%、12%、10%、3%和2%,聚合反应温度100℃时可获得粘度为5 Pa.s,固含量约45%的水性羟基丙烯酸树脂。

| Abstract: | The water-borne hydroxyl acrylic resin was prepared by semi-continuous solution polymerization technology using methyl methacrylate(MMA),styrene(St),and butyl acrylate(BA) as main monomers,acrylic acid(AA),hydroxyethyl acrylate(HEA)and isobornyl methacrylate(IBOMA)as functional monomers and finally adding water for dispersion.The effects of monomer ratio,initiator(BPO) amount,temperature,chain transfer agent(DDM)amount and functional monomer amount on the properties of resin were investigated by FT-IR,transparency analysis and viscosity analysis.The results showed that when the mass fraction of AA,HEA,IBOMA,BPO and DDM were 3%,12%,10%,3% and 2%,respectively,and polymerization reaction temperature was 100 ℃,the aqueous hydroxy acrylic resin was obtained with viscosity 5 Pa·s and solids content about 45%. |
