Slump-retaining water reducer and preparation method thereof
The invention discloses a slump-retaining water reducer and a preparation method thereof. The water reducer is obtained through the following step: an unsaturated polyether macromonomer A and an unsaturated alkenyl phosphorus monomer B, probably added with an unsaturated carboxylic ester monomer C, are copolymerized in an aqueous solution at the temperature of 20-110 DEG C in the presence of an initiator and a chain transfer agent. The slump-retaining water reducer has high slump retention capability, environmental protection and excellent performance.
