专利名称:一种阻泥型混凝土减水剂及其制备方法申请号:CN201210258594.7申请日:2012.07.24公开(公告)号:CN102808629A公开(公告)日:2012.11.14申请(专利权)人:苏州鼎恩建材科技有限公司本发明涉及减水剂技术领域,特别涉及一种阻泥型混凝土减水剂,其包括如下组成:0.5%~3%季铵盐型粘土稳定剂,0.5%~1.5%无机钾盐,3%~10%有机磷系列阻垢剂,15%~20%聚羧酸高性能混凝土减水剂,70.7%~78.5%水。本发明利用季铵盐型粘土稳定剂和无机钾盐来减少粘土表面扩散双电层厚度和Zeta电位,抑制粘土的膨胀与分散,利用有机磷系列阻垢剂吸附在粘土表面,由于有机磷系列阻垢剂的分子量较小,因此较少量的有机磷系列阻垢剂就能在粘土表面实现较好的吸附,效果显著。同时,本发明还公开了阻泥型混凝土减水剂的制备方法,该方法工艺简单,操作可
Patent CN201210258594 Application Date: 2012.07.24 Disclosure of the Invention (Disclosure No .: CN102808629A Publication Date: 2012.11.14 Applicant (Patented) Person : Suzhou Ding En Building Material Technology Co., Ltd. The present invention relates to the technical field of water reducer, in particular to a moisture-resistive concrete dewatering agent which comprises the following components: 0.5% to 3% of a quaternary ammonium salt clay stabilizer, 0.5% 1.5% inorganic potassium salt, 3% ~ 10% organic phosphorus scale inhibitor, 15% ~ 20% polycarboxylate high performance concrete water reducer, 70.7% ~ 78.5% water. The invention utilizes the quaternary ammonium salt type clay stabilizer and the inorganic potassium salt to reduce the thickness of the diffusion electric double layer and the Zeta potential on the surface of the clay and restrain the swelling and dispersion of the clay; the organic phosphorus series scale inhibitor is adsorbed on the surface of the clay; Scale inhibitor of smaller molecular weight, so a smaller amount of organophosphorus scale inhibitor can achieve better adsorption on the clay surface, the effect is significant. At the same time, the invention also discloses a preparation method of a mud-resisting type concrete water-reducing agent. The method has the advantages of simple process,
