The wet mixed mortar chemical functional material PC-2 was synthesized by monomers including 4-hydroxybutyl vinyl ether polyoxyethylene ether, acrylic acid, 4-vinylbenzenesulfonic acid and mono-2-(methacryloyloxy)ethyl succinate.The effects of different side chain lengths, the dosage of 4-vinylbenzenesulfonic acid and mono-2-(methacryloyloxy)ethyl succinate on the properties of wet-mixed mortar chemical functional materials were investigated. It had been verified by test that compared with PC-1, PC-2 could effectively reduce the consistency loss rate of wet mixed mortar, improved the water retention rate of wet mixed mortar, the tensile bond strength of 14d and the compressive strength of 7d and 28d. In the process of pumping and spraying construction, PC-2 had better performance and coud meet the requirement of continuous supply.
