The invention provides a machine-made sand regulator and a preparation method thereof. The machine-made sand conditioning agent is prepared by compounding a dispersing agent, a viscosity conditioning agent, a deflocculating agent and polymeric polyol, and the dispersing agent is a medium-molecular-weight polymer prepared by adding 3-(N-allylamino) propyltrimethoxysilane and epoxide and then polymerizing with an alcohol ether small monomer; the viscosity modifier and the deflocculating agent are prepared by addition of N-ethyl methacrylamide and epoxide and addition of tiglic acid and epoxide respectively. The machine-made sand conditioning agent provided by the invention can improve the strength, dispersity and working performance of concrete, has good water solubility and good compatibility with a polycarboxylic acid water reducer, and after the machine-made sand conditioning agent is doped into machine-made sand concrete, a concrete mixture has good cohesiveness and water-retaining property, so that the problems of poor workability and the like of machine-made sand in the prior art are effectively solved.
本发明提供了一种机制砂调节剂及其制备方法。所述机制砂调节剂由分散剂、粘度调节剂、抗絮凝剂和聚合多元醇复配所得，所述分散剂由3‑(N‑烯丙基氨基)丙基三甲氧基硅烷与环氧化物加成，再与醇醚小单体聚合制备中分子量聚合物；所述粘度调节剂、抗絮凝由N‑乙基甲基丙烯胺、惕格酸分别与环氧化物加成制得。本发明提供的机制砂调节剂可提高混凝土的强度、分散性以及工作性能，其水溶性好，与聚羧酸减水剂相容性好，掺入机制砂混凝土中后，混凝土拌合物具有较好的黏聚性、保水性，有效解决了现有技术中机制砂后和易性变差等问题。
