摘要
以甲基丙烯酸月桂酯(LMA)、甲基丙烯酸甲酯(MMA)、乙烯基三甲氧基硅烷(A171)为单体,偶氮二异丁腈(AIBN)为引发剂,合成了甲基丙烯酸月桂酯-甲基丙烯酸甲酯-乙烯基三甲氧基硅烷共聚物溶剂型分散剂。探讨了单体配比、引发剂用量、反应时间、有机硅单体用量对共聚物分散剂性能的影响。结果表明,单体配比m(LMA)∶m(MMA)∶m(A171)=2∶1∶0.4,引发剂(AIBN)用量为单体总量的1%,反应时间为6h时,所制得LMA-MMA-A171三元共聚物单体转化率最高,对颗粒的分散效果最佳。制备镨黄溶剂型分散体系的最佳分散条件:分散剂用量为20%,溶剂为200#溶剂油。该体系中,颜料颗粒的平均粒径为387.9nm。
The copolymer dispersant was synthesized using lauryl methacrylate （LMA）, methyl methacrylate （MMA） and vinyl trimethoxy silane A171. The copolymers structure was characterized by FT-IR. The influences of monomer ratio of methacrylate/methyl methacrylate/vinyl trimethoxy silane, amount of initiator, polymerization time on copolymer performance were discussed. The results show that when the mass ratio of LMA, MMA and A171 is 2 ： 1：0.4, 1% of the mass fraction of initiator on total monomers, and the reaction time is 6h, the copolymer has the highest conversion rate and shows an excellent dispersion efficiency. The optimal dispersion conditions are as follows： the amount of copolymer dispersant of 20%, solvent oil 2001. as solvent. In this dispersion system, the average particle size of pigment is 387.9nm.
