The invention discloses a concrete pumping agent capable of preventing pipe blockage and water seepage. The concrete pumping agent is characterized in being prepared from the following components in parts by weight: 4 to 7 parts of di (2-chloroethyl) hydrophosphate/piperazine-N, N-bis (2-hydroxyethane sulfonic acid) disodium salt polycondensate, 0.2 to 0.5 part of hyperbranched polyamino acid, 10to 15 parts of maleimide-tri (ethylene glycol)-propionic acid/triethanolamine oleate soap/vinyl phosphonic acid copolymer, 2 to 4 parts of kleemanite, 0.1 to 0.3 part of carboxymethyl chitosan and 30to 40 parts of water. The invention further provides a preparation method of the concrete pumping agent capable of preventing pipe blockage and water seepage. The concrete pumping agent disclosed by the invention is good in adaptability to cement, good in pumping effect, excellent in comprehensive performance, small in mixing amount, small in negative influence on the comprehensive performance ofconcrete, stable in quality and safe and environment-friendly to use, and the concrete added with the pumping agent is good in workability, excellent in pumpability and free of a water seepage phenomenon.
本发明公开了一种不堵管沁水的混凝土泵送剂，其特征在于，是由如下重量份的各组分制成：二(2‑氯乙基)磷酸氢酯/哌嗪‑N,N‑双(2‑羟基乙烷磺酸)二钠盐缩聚物4‑7份、超支化聚氨基酸0.2‑0.5份、马来酰亚胺‑三(乙烯乙二醇)‑丙酸/三乙醇胺油酸皂/乙烯基膦酸共聚物10‑15份、水羟磷铝锌石2‑4份、羧甲基壳聚糖0.1‑0.3份、水30‑40份。本发明还提供了所述不堵管沁水的混凝土泵送剂的制备方法。本发明公开的混凝土泵送剂对水泥的适应性好，泵送效果佳、综合性能优异，掺量少，对混凝土综合性能负面影响小，质量稳定，使用安全环保，添加了这种泵送剂的混凝土和易性佳、可泵性优越，不会出现沁水现象。
