Efficient concrete mud inhibitor as well as preparation method and application thereof
The invention relates to the field of concrete, in particular to an efficient concrete mud inhibitor and a preparation method and application thereof.The efficient concrete mud inhibitor is prepared from, by weight, 20-60 parts of organic phosphine compound, 5-15 parts of acrylic ester, 20-40 parts of lignosulfonate, 0.5-2 parts of chain transfer agent, 5-10 parts of polyethylene glycol and 20-80 parts of water. The mud inhibitor is applied to concrete to cooperate with a water reducing agent, so that the mechanical properties such as compressive strength of the concrete can be remarkably improved, cement particles are dispersed, the water reducing capacity of cement is improved, the addition amount is small, the cost is low, the preparation process is simple, and wide application prospects are achieved.
本发明涉及混凝土领域，尤其涉及一种高效混凝土阻泥剂及其制备方法和应用，按重量份计，制备原料包括：有机膦化合物20‑60份、丙烯酸酯5‑15份、木质素磺酸盐20‑40份、链转移剂0.5‑2份、聚乙二醇5‑10份、水20‑80份。本发明所述的阻泥剂应用于混凝土中协同减水剂可显著提高混凝土的抗压强度等力学性质，分散水泥颗粒，提高水泥减水能力，添加量少，成本低，制备工艺简单，具有广阔的应用前景。
