Fluorescent polycarboxylate superplasticizer and preparation method thereof
A fluorescent polycarboxylate superplasticizer and a preparation method thereof. The preparation process of the polycarboxylate superplasticizer is as follows. Firstly, a redox radical polymerization is performed on a monomer of an unsaturated acid and a derivative thereof, and an unsaturated polyether monomer to form a polycarboxylate superplasticizer pre-product. Then, the polycarboxylate superplasticizer pre-product is subjected to an esterification reaction with an organic molecule having a fluorescent property to obtain the fluorescent polycarboxylate superplasticizer. The method effectively reduces the reaction difficulty and makes the reaction rapid and efficient. The fluorescent polycarboxylate superplasticizer is non-toxic and non-polluting, and has good controllability in the production process and less side reactions. The fluorescent polycarboxylate superplasticizer can be applied to different kinds of cement, having a high water-reducing rate, and a relatively high cost performance and competitive advantage.
