摘要
实验以甲基丙烯酸、混合醇及醋酸乙烯酯为原料,经过先酯化后聚合,合成了一种新型的甲基丙烯酸混合酯-醋酸乙烯酯聚合物降凝剂,研究了其降凝性能。结果表明:在n(甲基丙烯酸):n(混合醇)=1:1、w(对甲苯磺酸)=2%、w(二甲苯)=60%条件下酯化反应2 h,然后在w(醋酸乙烯酯)=30%和w(过氧化苯甲酰)=1.5%、80℃反应5 h条件下制备的降凝剂具有最佳的降凝效果。当降凝剂的添加量为0.5%时,可使沈阳长城润滑油有限公司生产的150SN润滑油基础油凝点降低17℃。
The synthesis and pour point depressing performance of methacrylate ester-vinyl acetate polymer was studied. The optimized pour point depressing performance of the depressant was obtained by adding w ( vinyl acetate ) = 3 0 % and w ( BPO ) = 1. 5 % to the prepared compound for 5 h at 8 0 ℃,which was prepared by mixing n(methacrylic acid) : n(mixed alcohol)= 1 : 1, w(p-toluenesulfonic acid)=2% and w(dimethylbenzene)=60% for 2 ho SP of the 150SN lubricant (Shenyang Greatwall Lubricant Group Co. ) was lowered by 17 ℃ with 0.5% (w) of the depressant.
