Phosphorylated polycondensate as high efficiency water reducing agent and preparation method thereof
The present invention discloses a phosphorylated polycondensate high-performance water-reducing agent with a phosphorylated melamine derivative, instead of a conventional carboxyl group or sulfonic group, as a main adsorption group. The use of aryl alkoxypolyether as a side chain of the polymer provides a strong steric effect to improve the dispersibility and dispersion-retaining properties of the polymer. A polycondensate high-performance water-reducing agent and a method for preparing the same provided by the present invention have excellent overall performance, high adaptability for current low-grade raw materials of concrete, strong market demands, and vast application prospects. Additionally, the polycondensate has an advanced preparation process provided with the characteristics of industrially scalable production, which offers the prospect of a core technology in the field of water-reducing agent of concrete so as to promote development of the industry.
