一种β-萘磺酸甲醛缩合物季铵盐型混凝土外加剂

Beta-naphthalenesulfonic-acid formaldehyde condensation compound quaternary ammonium salt type additive of concrete

Abstract

本发明涉及一种萘磺酸甲醛缩合物季铵盐型水泥混凝土聚合物添加剂。在水泥混凝土中掺入少量外加剂便可显著改善水泥混凝土的力学性能、工作性能和耐久性能,从而满足不同工程对水泥混凝土的特殊要求。为此,研制性能优异的水泥混凝上外加剂一直是国内外研究的热点。本发明采用离子交换手段制备了六种不同季铵阳离子对应的β-萘磺酸甲醛缩合物盐。它们作为水泥混凝土添加剂,具有显著的分散能力和减水增强早强功能。
The present invention relates to a naphthalenesulfonic acid formaldehyde condensate quaternary ammonium salt type cement concrete polymer additive. By adding a small amount of additive to the cement concrete the mechanical property, working property and endurance quality of the cement concrete can be obviously improved. For this purpose, said invention adopts an ion exchange measure to prepare six different quaternary cationics correspondent beta-naphthalene-sulfonic acid formaldehyde condensate salts. They can be used as additives for cement concrete, and possesses excellent dispersion effect and water-reducing, reinforcing and high early strength function.
