A self-anticorrosion polycarboxylate water reducing agent and a preparing method thereof
A self-anticorrosion polycarboxylate water reducing agent is provided. The water reducing agent is prepared by free radical polymerization of carboxylic acid monomers A, high-molecular-weight polyether macromonomers B and functionally modified polyether macromonomers C in a mole ratio of 1-5:1:0.001-0.02. A preparing method of the water reducing agent and applications of the water reducing agent in concrete preparation are also provided. According to the water reducing agent, anti-bacterial functional groups and unsaturated monomers forming the water reducing agent are subjected to the free radical polymerization, so that the water reducing agent itself has anti-bacterial and anticorrosion functions. A subsequent compounding process is free of addition of preservatives. The shelf life of the polycarboxylate water reducing agent is significantly prolonged. The water reducing agent can be preserved for 12 months without deterioration. The water reducing agent is harmless to human and the environment and is environmental friendly.
