Polyether macromonomer synthesized polyacid water reducing agent and preparation method thereof
The invention discloses a polyether macromonomer synthesized polyacid water reducing agent and a preparation method thereof, and particularly relates to the field of cement dispersants. The mainly used materials include the following materials: 180-200 parts of isopentenol polyoxyethylene ether, 60-70 parts of methallyl alcohol polyoxyethylene ether, 20-30 parts of acrylic acid, 15-20 parts of sodium methallyl sulfonate, 14-16 parts of a chain transfer agent, 680-720 parts of water, 40-60 parts of an additional stabilizer and a plurality of regulators. By adding the chain transfer agent and the additional stabilizer into the raw materials, the admixture can be accurately metered and uniformly dispersed, damp caking is prevented, the performance of the concrete is ensured, the cement setting time is delayed, the concrete has good dispersity and slump loss resistance, and the indexes of the water reducing rate and the compressive strength ratio meet the technical requirements of first-class products; use requirements of users are met.
本发明公开了一种聚醚大单体合成聚发酸减水剂及其制备方法，具体涉及水泥分散剂领域，其中所使用的主料包括以下重量份数的原料：异戊烯醇聚氧乙烯醚180‑200份、甲基烯丙醇聚氧乙烯醚60‑70份、丙烯酸20‑30份、甲基丙烯磺酸钠15‑20份、链转移剂14‑16份、水680‑720份、外加稳定剂40‑60份和调节剂若干。本发明通过在原料中添加链转移剂和外加稳定剂，可使外加剂计量准确、分散均匀和防止受潮结块，保证混凝土的性能，且会延缓水泥凝结时间，对混凝土具有良好的分散性和保坍性，减水率、抗压强度比的指标均满足一等品技术要求，满足使用者的使用需求。
