Air-entraining type modified naphthalene water reducer and preparation method thereof
The invention provides an air-entraining type modified naphthalene water reducer and a preparation method thereof, and the air-entraining type modified naphthalene water reducer is obtained by polymerization reaction of naphthalene sulfonic acid prepared by reaction of concentrated sulfuric acid and naphthalene, naphthol phosphate prepared by reaction of naphthol and phosphorus oxychloride, and sodium alkyl naphthalene sulfonate. Compared with a traditional naphthalene water reducer, the prepared air-entraining type modified naphthalene water reducer has the advantages that the water reducing and slump retaining effects are obviously improved, the air-entraining type modified naphthalene water reducer has certain air-entraining performance, and the state of concrete is greatly improved.
本发明提供一种引气型改性萘系减水剂及其制备方法，本发明所述的引气型改性萘系减水剂，是用浓硫酸与萘反应制备的萘磺酸，萘酚与三氯氧磷反应制备的萘酚磷酸酯，和烷基萘磺酸钠进行聚合反应得到。本发明制备的引气型改性萘系减水剂，与传统萘系减水剂相比，不仅减水和保坍效果明显提升，而且具有一定的引气性能，大大改善了混凝土的状态。
