Special mud-resistant sacrificial agent for polycarboxylate-type water reducing agent and preparation method of special mud-resistant sacrificial agent
The invention discloses a special mud-resistant sacrificial agent for a polycarboxylic acid water reducing agent. The special mud-resistant sacrificial agent comprises the following raw materials in parts by weight: 50-90 parts of monomers, 0.1-1 part of a chain transfer agent, 0.1-2 parts of an initiator, 0.1-10 parts of a complexing agent, 10-20 parts of polyethylene glycol, 1-30 parts of a neutralizer and 100-250 parts of deionized water. The monomers comprise acrylamide, acrylic acid, dimethyl diallyl ammonium chloride and dimethylaminoethyl methacrylate, and the complexing agent is ethylene diamine tetraacetic acid disodium salt and beta-cyclodextrin. The prepared special mud-resistant sacrificial agent for the polycarboxylic acid type water reducing agent has an excellent multi-dimensional protection effect, has a good neat paste fluidity and slump keeping effect after being used, is suitable for being popularized in the field of cement, and has a wide development prospect.
本发明公开了一种聚羧酸系减水剂专用抗泥牺牲剂，原料包含以下重量份：50～90份单体、0.1～1份链转移剂、0.1～2份引发剂、络合剂0.1～10份、聚乙二醇10～20份、中和剂1～30份、去离子水100～250份。单体包括丙烯酰胺、丙烯酸、二甲基二烯丙基氯化铵和甲基丙烯酸二甲氨乙酯，络合剂为乙二胺四乙酸二钠、β‑环糊精。制得的聚羧酸系减水剂专用抗泥牺牲剂具有优异的多维度保护作用，使用后具有良好的净浆流动度和坍落度保持效果，适宜在水泥领域推广，具有广阔的发展前景。
