Polycarboxylate superplasticizer with mud preventing effect and preparation method of polycarboxylate superplasticizer
The invention discloses a polycarboxylate superplasticizer with a mud preventing effect. The structural general formula of the polycarboxylate superplasticizer is as shown in the description, wherein R1 is H or CH3, R2 is H or COOM, R3 is an alkyl of C1 to C3, and M is H, Na, K or NH4. The invention also provides a preparation method of the polycarboxylate superplasticizer with the mud preventing effect. The superplasticizer synthesized by use of the process is applied to concrete within the aggregate mud content range of 0-8%, and a good application effect can be obtained through direct use without physical compounding.
