Polycarboxylic acid high performance water reducer synthesized by one step, preparation method for polycarboxylic acid high performance water reducer and application of polycarboxylic acid high performance water reducer
The invention discloses a polycarboxylic acid high performance water reducer synthesized by one step, a preparation method for the polycarboxylic acid high performance water reducer and application of the polycarboxylic acid high performance water reducer. A product with a comb-like structure: the polycarboxylic acid high performance water reducer is obtained by one-step synthesis by carrying out a copolymerization reaction on an allyl polyoxyethylene ether APEG macromonomer and a carboxylic acid monomer under the action of an initiator and a chain transfer agent sodium methallyl sulfonate MAS. By doping the polycarboxylic acid high performance water reducer, cement can be endowed with relatively great flowability and concrete is endowed with a relatively high water-reducing rate, so that mixed water is uniformly distributed in a cement-based material and can be maintained stable for a long time.
