The invention belongs to the field of concrete admixture application, and discloses a novel nonionic anti-mud drag reducer and a preparation method thereof.The nonionic anti-mud drag reducer is prepared from, by weight, 20%-50% of nonionic monomers, 1%-10% of complexing agents, 20%-30% of polyether amine and the balance deionized water, the preparation method of the nonionic anti-mud drag reducer comprises the following steps: step 1, weighing raw materials; step 2, adding water into the reaction container, heating to 20-40 DEG C, adding polyether amine into the water, and stirring; and step 3, adding a complexing agent and a nonionic monomer, stirring, and cooling to room temperature to obtain the final product nonionic anti-mud drag reducer. The water reducing agent has good compatibility with the water reducing agent, does not influence the performance of the water reducing agent, can be preferentially adsorbed in clay in concrete when being combined with the water reducing agent, plays a role in assisting the water reducing agent in resisting mud and reducing resistance, and can ensure that the dosage of the water reducing agent is correct in the construction process.
本发明属于混凝土外加剂应用领域，公开了一种新型非离子抗泥减阻剂及其制备方法，非离子抗泥减阻剂包括如下百分比含量的原料：20%‑50%的非离子单体、1%‑10%的络合剂、20%‑30%的多醚胺、其余部分为去离子水，非离子抗泥减阻剂的制备方法包括步骤1、称取原料；步骤2、向反应容器中加入水，待升温加热至20‑40℃，将多醚胺加入水中，搅拌；步骤3、加入络合剂与非离子单体，搅拌，冷却至室温，即得最终产品非离子抗泥减阻剂。本发明与减水剂的相容性较好，不影响减水剂的性能，与减水剂结合时，可以优先吸附在混凝土中的粘土中，起到辅助减水剂的抗泥减阻作用，能够保证在施工过程中减水剂的用量正确。
