Anti-montmorillonoid high-efficiency amphiprotic polycarboxylate superplasticizer and preparation method thereof
The invention belongs to the technical field of concrete water reducing agents, and discloses an anti-montmorillonoid high-efficiency amphiprotic polycarboxylate superplasticizer and a preparation method thereof. The anti-montmorillonoid high-efficiency amphiprotic polycarboxylate superplasticizer is prepared from a monomer A, a monomer B and a monomer C under the action of a catalyst, wherein the monomer A is unsaturated carboxylic acid or acid anhydride; the monomer B is enol polyoxyethylene ether; the monomer C is an SPB monomer containing N<+> cation with triplebond; the SPB monomer is prepared from methacrylic acid dimethylamine ethyl ester and 1,3-propane sultone through reaction. The anti-montmorillonoid high-efficiency amphiprotic polycarboxylate superplasticizer disclosed by the invention has the advantages of high efficient water reduction effect and montmorillonoid resistance.
