Title:
POLYCARBOXYLIC WORKABLE REGULATOR PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/114581
Kind Code:
A1
Abstract:
A polycarboxylic workable regulator preparation method. A workable regulator is obtained by free radical polymerization of free radicals in an aqueous solution of a monomer mixture. The monomer mixture comprises a polymerizable reducing agent, an unsaturated acid, and an unsaturated ester; the polymerizable reducing agent has a tert-amino group and a cellulose ether structure. The prepared polycarboxylic workable regulator can obviously improve the wrapping property and mobility of concrete, reduce a bleeding segregation phenomenon, and can also improve the dispersibility and dispersion retention of the concrete.
