Anti-flocculation polymer and anti-adsorption concrete admixture containing anti-flocculation polymer
The invention relates to the technical field of building materials, in particular to an anti-flocculation polymer and an anti-adsorption concrete admixture containing the anti-flocculation polymer. The anti-flocculation polymer is prepared from the following components in parts by weight: 30 to 50 parts of polyurethane-acrylic emulsion, 10 to 15 parts of polyvinylidene fluoride emulsion and 10 to 15 parts of polysiloxane. The concrete admixture comprises the following components in parts by weight: 15-25 parts of an anti-flocculation polymer, 1-3 parts of sodium citrate and 1-3 parts of calcium carbonate. The anti-flocculation polymer is prepared from the polyurethane-acrylic emulsion, the polyvinylidene fluoride emulsion and the polysiloxane, the adsorption resistance of machine-made sand and cement particles can be improved, dispersion of the machine-made sand and the cement particles in concrete is facilitated, and therefore the influence of a residual flocculating agent in the machine-made sand on the concrete is reduced. The concrete admixture provided by the invention not only can improve the adsorption resistance of the concrete admixture to machine-made sand and cement particles, but also can reduce and remove rust and dirt on concrete.
本发明涉及建筑材料的技术领域，尤其是涉及一种抗絮凝聚合物及含有抗絮凝聚合物的抗吸附性混凝土外加剂。抗絮凝聚合物包括如下重量份的组分，聚氨酯‑丙烯酸乳液30‑50份、聚偏氟乙烯乳液10‑15份和聚硅氧烷10‑15份。混凝土外加剂包括如下重量份的组分，抗絮凝聚合物15‑25份，柠檬酸钠1‑3份，碳酸钙1‑3份。本申请通过采用聚氨酯‑丙烯酸乳液、聚偏氟乙烯乳液和聚硅氧烷制备出一种抗絮凝聚合物，可以提高机制砂和水泥颗粒的抗吸附性，有助于分散混凝土中的机制砂和水泥颗粒，从而降低机制砂中残留的絮凝剂对混凝土的影响。本申请的混凝土外加剂不仅能够提高混凝土外加剂对机制砂和水泥颗粒的抗吸附性，还能够还原并除去混凝土上的铁锈和污物。
