Preparation method of super high-early-strength polycarboxylate superplasticizer
The invention relates to a preparation method of a super high-early-strength polycarboxylate superplasticizer. The super high-early-strength polycarboxylate superplasticizer is prepared by performing a free radical polymerization reaction on a low-foam polyether macromonomer A, a polyether macromonomer B, a micromonomer C and a micromonomer D in an aqueous medium under the action of a water-soluble redox system, wherein the molar ratio of the monomers A, B, C and D is (0.2-1):(3-9):(0.5-3). The functional polycarboxylate superplasticizer has the advantages of obviously improving the early hydration of the cement, improving the early strength of the concrete, improving the early strength of the concrete and remarkably enhancing the compressive strength of the concrete, and the advantages of excellent working performance, low apparent viscosity and convenience for construction of the newly mixed concrete.
