摘要： The present invention provides a preparation method of hyperbranched polycarboxylic acid type copolymer cement dispersant, including: Monomer A, B and C undergo a free radical copolymerization in an aqueous medium. The molar ratio of Monomer A, Monomer B and Monomer C conforms to B/A−A−2−10 and C/(A+B−C)−0.02−0.08. Monomer A is expressed by General Formula (1), where, R1 is H or a methyl; X1═O, CH2O, CH2CH2O; m is an integer from 5 to 200.Monomer B is expressed by General Formula (2), where, R2 is H or COOM; R3 is H or CH3 and M is H, Na, K or NH4;Monomer C is expressed by General Formula (3), where, R4 is H or methyl; X2═O, CH2O, CH2CH2O; Y═CH2, CH2CH2, CH(CH3), CH2CH2CH2, CH(CH3)CH2, C(CH3)2 and n is an integer from 5 to 200.

摘要： A water-dispersible amphoteric polyurethane and a preparation method therefor. The water-dispersible amphoteric polyurethane is prepared from a polyisocyanate compound, a polyol compound, a dial compound having an anionic group or a potential anionic group, a compound having a tertiary or quaternary amine cationic group at least having two active H functional groups and a polyamine compound having a polyoxyethylene group. During preparation, the feeding order of the dial compound and the compound having a tertiary or low-molecular quaternary amine cationic group is controlled, and then neutralization and chain extension are performed, to obtain the target product. Also disclosed is a use of the water-dispersible amphoteric polyurethane in reinforcing concrete, wherein the water-dispersible amphoteric polyurethane is present in an amount of 0.1% to 5%, based on the total weight of the concrete.
