Abstract Amicro-crosslinking polycarboxylate superplasticizer M42 was synthesized by using isopentanol polyoxyethylene ether (TPEG-2400), acrylic acid (AA), hydroxyethyl acrylate (HEA) and amino-terminated polyethylene glycol(H2N-PEG-NH2) as the main raw materials. The effects of the ratio of acid to ether, the dosage of HEA and amino-terminated polyethylene glycol on polycarboxylate superplasticizer were investigated. The molecular structure was confirmed by infrared spectrum analysis. The surface adsorption of M42 on montmorillonite was analyzed by infrared spectrum and thermogravimetric analysis (TG). The effect of montmorillonite on the interlayer adsorption of M42 was analyzed by XRD. Finally, the effects of M42 on the fluidity, concrete loss and compressive strength of cement slurry containing montmorillonite were evaluated. The results show that when the ratio of acid to ether is 2.0 and the amount of HEA and amino-terminated polyethylene glycol is 2.9% and 4.4% of the amount of large monomer, respectively, the product has anti-mud, anti-slump and water-reducing effects at the same time, and its comprehensive properties are better than those of similar products in the market.
