一种高性能聚羧酸减水剂及其制备方法
摘要：
本发明公开了一种高性能聚羧酸减水剂，由以下重量份的原料制备而成：甲基丙烯酸聚乙二醇单甲醚酯70‑95份、过硫酸铵1‑5份、过硫酸钾0.5‑2份、烯丙基磺酸钠0.5‑3份、甲基丙烯磺酸钠0.35‑0.5份、去离子水60‑100份。本发明能达到30%‑40%的减水率，具有0.15%‑0.3%的低掺量，保坍性好，具有增强混凝土抗压强度的特点。
摘要（英）：

The invention discloses a high-performance polycarboxylic acid water reducing agent. The high-performance polycarboxylic acid water reducing agent is prepared from, by weight, 70-95 parts of methacrylic acid polyethylene glycol monomethyl ether ester, 1-5 parts of ammonium persulfate, 0.5-2 parts of potassium persulfate, 0.5-3 parts of sodium allysulfonate, 0.35-0.5 part of sodium methallyl sulfonate and 60-100 parts of deionized water. The high-performance polycarboxylic acid water reducing agent can reach the water-reducing rate of 30%-40%, and have the advantages of having low accretion of0.15%-0.3% and good keeping slump, and strengthening the compressive strength of concrete.
