Abstract

Green environmental protection type polycarboxylic acid water reducing agent has been widely concerned in the field of building materials because of its excellent dispersion performance and environmental protection properties. In this paper, the synthesis method of this kind of water reducing agent, optimized the molecular structure with low toxicity, and developed a new polycarboxylic acid water reducing agent with low environmental load. By optimizing the synthesis process, the molecular chain structure is accurately regulated to improve its adaptability in self-leveling mortar. Combined with the fluidity, mechanical properties, volume stability and other indicators, to systematically evaluate its application effect. The results show that the green water reducing agent not only guarantees the construction performance, significantly reduces the risk of environmental pollution, provides technical support for the green upgrade of self-leveling materials, and has good engineering application prospect and promotion value.
