Solid polycarboxylate superplasticizer preparation system
The invention relates to polycarboxylate superplasticizer preparation, in particular to a solid polycarboxylate superplasticizer preparation system which is composed of a quantitative peristaltic pump, a mixer and a reaction pipeline. Methyl butenyl polyethylene acrylic acid, methacrylic acid polyethylene glycol monomethyl ether ester, acrylic acid and maleic acid ethylene glycol monoester are selected as polymerization monomers, azodiisobutyronitrile is selected as a free radical initiator, and mercaptopropionic acid is selected as a chain transfer agent; and the synthesized polycarboxylate superplasticizer is narrow in molecular weight and high in water reducing rate, and the performance of the polycarboxylate superplasticizer is close to that of a liquid superplasticizer product.
本发明涉及聚羧酸减水剂制备，更具体而言，涉及一种固体型聚羧酸减水剂制备系统，该系统由定量蠕动泵、混合器、反应管道三个部分构成；选用‑甲基丁‑烯基聚乙丙烯酸、甲基丙烯酸聚乙二醇单甲醚酯、丙烯酸、马来酸乙二醇单酯作为聚合单体，偶氮二异丁腈为自由基引发剂，巯基丙酸为链转移剂；合成的聚羧酸减水剂分子量窄，减水率高，性能接近液体减水剂产品。
