Anti-mud water reducing agent and preparation method thereof
The invention relates to the field of water reducing agents, and particularly discloses an anti-mud water reducing agent and a preparation method thereof. The invention relates to a water-based polyurethane adhesive which comprises the following components in parts by weight: 340-355 parts of polyether monomer, 12-16 parts of H6, 0.6-1 part of vitamin C, 30-40 parts of functional monomer, 2-4 parts of CJ-01, 12-18 parts of H1 and 550-600 parts of water. The functional monomer is a functional monomer formed by esterification of 4-phenyl butanol and metacrylic acid ester under the action of a catalyst and a polymerization inhibitor. 4-phenylbutanol and methacrylic acid are subjected to an esterification reaction to obtain a new functional monomer, so that the problem that in the prior art, the selection of functional monomers is few is solved; the effect is unstable, and the performance of the concrete is influenced.
本申请涉及减水剂领域，具体公开了一种抗泥减水剂及其制备方法。其成分按重量份计为：聚醚单体:340‑355、H6:12‑16、维生素C：0.6‑1、功能单体：30‑40、CJ‑01：2‑4、H1：12‑18、水：550‑600；所述功能单体为：4‑苯基丁醇和甲基丙烯酸酯在催化剂与阻聚剂下酯化形成的功能单体。其中的利用4‑苯基丁醇和甲基丙烯酸酯化反应得到新的功能单体，解决了现有技术中功能单体选择少；效果不稳定，会影响混凝土性能的技术问题。
