Concrete admixture sensitive inhibitor as well as preparation method and application thereof
The invention relates to a concrete admixture sensitive inhibitor as well as a preparation method and application thereof. The concrete admixture sensitive inhibitor comprises polyethylene glycol, polyethylene glycol monomethyl ether, acrylic acid, micromolecular monobasic acid, a polymerization inhibitor, a catalyst, a molecular regulator, an initiator and a reducing agent. According to the preparation method, monomers with different molecular weights are matched, a polymer with wide molecular weight distribution is prepared through a special synthesis process, and the sensitivity of the polycarboxylate superplasticizer is reduced through matching of macromolecules and micromolecules. The concrete admixture sensitive inhibitor prepared by the invention can be directly compounded with polycarboxylic acid water reducing agents, or can be directly added when the concrete is sensitive. According to the concrete admixture sensitive inhibitor prepared by the invention, the sensitivity of various factors such as the mixing amount, the variety, the water consumption, the temperature and the raw materials of the water reducing agent can be reduced.
本发明涉及一种混凝土外加剂敏感抑制剂、制备方法及应用，该混凝土外加剂敏感抑制剂包括：聚乙二醇、聚乙二醇单甲醚、丙烯酸、小分子一元酸、阻聚剂、催化剂、分子调节剂、引发剂、还原剂。其制备方法是利用不同分子量的单体搭配，通过特殊的合成工艺制备了分子量分布很宽的聚合物，利用大分子和小分子的搭配降低聚羧酸减水剂的敏感性。本发明制备的混凝土外加剂敏感抑制剂可直接与聚羧酸类减水剂复配，或在混凝土出现敏感时直接添加。本发明所制备的混凝土外加剂敏感抑制剂，能够降低减水剂掺量、种类、用水量、温度和原材料各种因素的敏感性。
