Sulphonate polymer cement grinding aid
The invention discloses a sulphonate polymer cement grinding aid, and belongs to the technical field of building materials. The cement grinding aid comprises the following constituents in parts by weight: 8-18 parts of sodium methallyl sulfonate, 5-8 parts of coal ash, 2-3 parts of sodium persulfate, 2-5 parts of ethyl acrylate, 2-8 parts of ammonium ferrous sulfate, 0.2-1.5 parts of ammonium acetate, 2-5 parts of methylallyl alcohol polyoxyethylene ether, 20-35 parts of water and 0.5-0.8 parts of a preservative. The cement grinding aid provided by the invention is improved in overall performance, can meet different requirements, and is low in production cost without affecting the fluidity of the cement; the most important is that the cement grinding aid has a good reinforcement effect for the cement after 28 days.
