The invention discloses a concrete pumping agent, which is characterized by being prepared from the following components in parts by weight: 10 to 20 parts of triazolyl terephthalic acid sulfate ionomer borate, 0.5 to 1.5 parts of zinc fluosilicate, 5 to 10 parts of 3-aminophenylboronic acid modified epoxy-terminated hyperbranched poly (amine-ester), 10 to 15 parts of polycarboxylic acid high-performance water reducing agent, 0.3-0.6 part of N, N-bis (2-ethoxyl)-2-aminoethanesulfonic acid, 0.1-0.3 part of a defoaming agent and 40-60 parts of water. The invention also discloses a preparation method of the concrete pumping agent. The concrete pumping agent disclosed by the invention is good in pumping effect and performance stability, high in adaptability to cement, excellent in plasticity maintaining performance, small in mixing amount, small in negative influence on comprehensive performance of concrete, low in preparation cost and safe and environment-friendly to use.
本发明公开了一种混凝土用泵送剂，其特征在于，是由如下按重量份计的各组分组成：基于三唑基对苯二甲酸基硫酸酯基离聚物硼酸盐10‑20份、氟硅酸锌0.5‑1.5份、3‑氨基苯硼酸改性端环氧基基超支化聚(胺‑酯)5‑10份、聚羧酸高性能减水剂10‑15份、N,N‑双(2‑羟乙基)‑2‑氨基乙磺酸0.3‑0.6份、消泡剂0.1‑0.3份、水40‑60份。本发明还公开了一种所述混凝土用泵送剂的制备方法。本发明公开的混凝土用泵送剂泵送效果和性能稳定性佳，与水泥的适应强，保塑性能优异，掺量少，对混凝土综合性能负面影响小，制备成本低廉，使用安全环保。
