Comprehensive polycarboxylate superplasticizer and preparation method thereof
The invention discloses a comprehensive polycarboxylate superplasticizer, which is prepared from the following raw materials: isopentenyl polyoxyethylene ether, 2-acrylamide-2-methyl propane sulfonic acid, 2-methacryloyloxyethyl trimethyl ammonium chloride, methacrylic acid-N, N-dimethylaminoethyl ester and N, N-dimethylacrylamide. The comprehensive polycarboxylate superplasticizer is a hyperbranched macromolecule, contains multifunctional groups, has good water reducing performance, slump retaining performance, drought strength performance and slow release performance, has good adaptability to cement and concrete, reduces energy consumption in the manufacturing process, and greatly reduces the production cost.
本发明公开了一种综合型聚羧酸减水剂，包括以下原料：异戊烯基聚氧乙烯醚、2‑丙烯酰胺‑2‑甲基丙烷磺酸、2‑甲基丙烯酰氧基乙基三甲基氯化铵、甲基丙烯酸‑N,N‑二甲氨基乙酯、N,N‑二甲基丙烯酰胺组成制备综合型聚羧酸减水剂。本发明的综合型聚羧酸减水剂是超支化大分子并含有多功能基团既有良好的减水性能，同时具有保坍性能、旱强性能、缓释性能，且对水泥、混凝土具有良好的适应性，制作过程减少能耗，大幅度降低生产成本。
