Special early-strength polycarboxylate superplasticizer for prefabricated parts and preparation method of special early-strength polycarboxylate superplasticizer
The invention discloses a special early-strength polycarboxylate superplasticizer for prefabricated parts. The special early-strength polycarboxylate superplasticizer is prepared by implementing copolymerization reaction on isopentenyl polyether and an acrylamide group monomer and acrylic polypropylene glycol monoester mixed solution together with dimethyl fumarate and a molecular weight modifier as well as an initiator. The special early-strength polycarboxylate superplasticizer disclosed by the invention is high in water reduction rate, high in early strength, relatively low in shrinkage rate, good in adaptability, free of formaldehyde pollution in the production process, and particularly applicable to prefabricated parts and cement products.
