摘要
先用马来酸酐（MA）和二乙醇胺（DEA）合成了单体M，后与丙烯醇（AA）、烯丙基聚氧乙烯醚（B－400）用过硫酸胺（APS）作引发剂，在水溶液中通过自由基聚合合成新型高分子水泥助磨剂，确定了最佳单体摩尔比：M：AA：B－400=1．0：1．2：0．5，引发剂用量为单体总质量的4．0％。将该助磨剂应用于水泥粉磨试验，并与空白对比：45μm筛余量降低34．3％；3～32μm细颗粒的含量提高了18．2％；3d，28d的抗压强度分别提高了15．7％，13．7％。
The small monomer M was synthesized with maleic anhydr ide （MA） and die thano 1 amine （DEA）. The Mand allyl alcoho 1 （AA）were then added into allyl polyeth enoxy e the r （B-400） to produce polymer cement grinding a idby aqueous solut ion polymerization, under the initiating effect of ammonium peroxydi sul fate, the optimal molar ratio of polyme r cement gr inding aid was M：A A：B-400=1：1. 2：0. 5, amount of initiator 4. 0%. The resul t s of the cement grinding aids test compared wi th black were as follows： sieved particles of 45μm reduced 34. 3%; the grains size of 3-32μm increased 18. 2%; 3d,28dcompres s ive streng th of cement pastes were increa sed by 15. 7%and 13. 7%.
