Retarding type water reducing agent and preparation method thereof
The invention relates to a delayed coagulation type water reducing agent. The structural general formula of the delayed coagulation type water reducing agent is (A) x (C) Y (TPEG) z, wherein A, TPEG and C respectively represent an unsaturated acid, an ester copolymer macromonomer and an unsaturated chitosan-polyglycerol monomer. The unsaturated chitosan-polyglycerol monomer is introduced to a molecular long chain of the retarding type water reducing agent, so that the retarding effect is met, the doping of additives is reduced, and the cost is reduced.
本发明涉及一种缓凝型减水剂，缓凝型减水剂结构通式为：(A)x(C)Y(TPEG)z；其中，A、TPEG、C分别代表不饱和酸、酯类共聚物大单体、不饱和壳聚糖‑聚甘油单体。本发明在缓凝型减水剂的分子长链上引入了不饱和壳聚糖‑聚甘油单体，在满足缓凝效果的同时，减少外加剂的掺入、降低成本。
