Ester polycarboxylate superplasticizer formula and preparation method thereof
The invention discloses an ester polycarboxylate superplasticizer formula, which comprises the following components in percentage by mass: 71-69% of methoxypolyethylene glycol, 10-30% of methacrylic acid, 2-4% of defoaming functional monomer, 1-3% of p-toluenesulfonic acid, 4-6% of hydroquinone, 34-35% of soft water, 0.32-0.34% of mercaptoacetic acid, 15-25% of an ammonium persulfate aqueous solution, 7.15-7.19% of a sodium hydroxide solution, 2-4% of an initiator, 2-4% of an unsaturated amide small monomer, 2-4% of an antiseptic bactericide, 2-4% of a thickener, 2-4% of a neutralizer, 2-4% ofa chain transfer agent and 2-4% of an organic reducing agent. The ester polycarboxylate superplasticizer formula has the technical effects that the problem of unstable quality caused by easy floatingand layering when a defoaming agent is mixed in the superplasticizer is solved, and the performance, the compressive strength and the slump retention capacity of a product are all excellent.
本发明公开了一种酯类聚羧酸减水剂配方，包括以下质量百分比的聚乙二醇单甲醚71～69％、甲基丙烯酸10～30％、消泡功能单体2～4％、对甲苯磺酸1～3％、对苯二酚4～6％、软水34～35％，巯基乙酸0.32～0.34％、过硫酸铵水溶液15～25、氢氧化钠溶液7.15～7.19％、引发剂2～4％、不饱和酰胺类小单体2～4％、防腐杀菌剂2～4％、增稠剂2～4％、中和剂2～4％、链转移剂2～4％和有机还原剂2～4％。该发明的技术效果为解决了消泡剂混合在减水剂中时，容易漂浮分层导致质量不稳定的情况，提高产品的性能和抗压强度与坍落度保持能力均表现优异。
