聚羧酸系水煤浆添加剂的合成研究

以丙烯酸、聚乙二醇为主要原料,制得聚乙二醇-丙烯酸酯类大分子单体,再将该大分子单体与乙烯基磺酸钠共聚制备一种新型高效聚羧酸系水煤浆添加剂。对加入该添加剂制得的水煤浆的各项性能测试(黏度,稳定性,流变性),表明该添加剂在用量为0.5%,平均粒径为30.86μm,对双鸭山煤的最高制浆浓度为68%。 The polyethylene glycol-acrylate ester has been synthesized through the esterification of acrylic(AA) and polyethylene glycol(PEO).Test results of the properties of CWS including stability and slurry ability show that the highest concentration is 68% for shuanyashan coal when used additive 0.5%,d50 30.86μm
