The method of synthesizing a carboxylic acid type high slump normal water reducer poly

The present invention belongs to the technical field of synthesis methods for concrete superplasticizer, specifically discloses a polycarboxylic acid type high water reducing agent slump retention at room temperature synthesis method, the method unsaturated polyoxyethylene ethers, unsaturated carboxylic acid as a raw material in the cement and can be an alkaline environment explain water discharge unsaturated carboxylic acid monomer release, in a room temperature environment, synthesized with tap water having a high slump properties polycarboxylate. Advantages of the present invention are as follows: 1, synthesized at room temperature, saves energy, i.e. environmentally safe and economical; 2, with tap water synthetic, further save production costs; 3, the addition of monomer release, the product has a strong slump properties , achieve the purpose of long-distance transportation of concrete, with strong market competitiveness.
