Mud-resistant polycarboxylate water reducer and preparation method thereof
The invention discloses a mud-resistant polycarboxylate water reducer, and relates to the technical field of concrete admixtures, wherein the structural general formula of the mud-resistant polycarboxylate water reducer is shown in the specification, wherein a=20-120, b=15-100, and c=10-40. The invention also provides a preparation method of the water reducer. The mud-resistant polycarboxylate water reducer and the preparation method thereof have the beneficial effects that the polycarboxylate water reducer is prepared by polymerizing compound C6-containing unsaturated ether and unsaturated acid according to a certain proportion, 4-mercaptobutyl vinyl ether is used as a substrate, sulfydryl is oxidized into sulfonic acid group through an oxidizing agent, and good mud resistance is achieved.
本发明公开一种阻泥型聚羧酸减水剂，涉及混凝土外加剂技术领域，其结构通式如下：其中a＝20‑120，b＝15‑100，c＝10‑40，本发明还提供上述减水剂的制备方法。本发明的有益效果在于：本发明以含复配C6不饱和醚、不饱和酸按照一定的比例聚合制备聚羧酸减水剂，4‑巯基丁基乙烯基醚为底物，通过氧化剂氧化巯基为磺酸基，具有很好的阻泥性。
