Fluorescent type polycarboxylate water reducer and preparation method thereof
The invention discloses a fluorescent type polycarboxylate water reducer and a preparation method thereof. The preparation process of the water reducer comprises the following steps: firstly, carryingout an oxidation-reduction free radical polymerization reaction on unsaturated acid and derivative monomers thereof and unsaturated polyether monomers to generate a water reducer pre-product, and then carrying out an esterification reaction on the water reducer pre-product and organic molecules with fluorescence properties to obtain the fluorescent type polycarboxylate water reducer. By adoptingthe method, the reaction difficulty is effectively reduced, the reaction is rapid and efficient, the toxicity and pollution are avoided, the controllability of the production process is good, the sidereactions are few, the adaptability to different kinds of cement is good, the water reducing rate is high, and the cost performance and the competitive advantage are strong.
本发明公开一种荧光型聚羧酸系减水剂及其制备方法，减水剂的制备过程是首先采用不饱和酸及其衍生物单体与不饱和聚醚单体进行氧化‑还原自由基聚合反应，生成减水剂预产物，再将减水剂预产物与有荧光属性的有机分子进行酯化反应得到荧光型聚羧酸系减水剂。用本发明方法有效降低了反应难度，反应迅速高效，无毒无污染，生产工艺可控性好，副反应少、对不同水泥品种适应性强，减水率高，具有较高的性价比和竞争优势。
