Environment-friendly concrete anti-freezing pumping agent and preparation method thereof
The invention discloses an environment-friendly concrete anti-freezing pumping agent. The pumping agent is characterized by comprising, by weight, 8-12 parts of N-phenyl-3-allyl propionate benzenesulfonamide/3-acrylamidophenylboronic acid/2-(5-phenyl-1H-tetrazole-1-yl)-3-thiophene-2-acrylic acid/N,N- bis(-2-hydroxyethyl) oleylamine copolymer, 15-25 parts of a polycarboxylic acid high-performance water reducer, 2-4 parts of chitosan quaternary ammonium salt, 1-2 parts of zinc nitrate, 1-3 parts of isothiourea propyl sulfate modified carboxymethyl cellulose, 2-4 parts of nano zinc oxide and 35-45 parts of water. The invention further discloses a preparation method of the environment-friendly concrete anti-freezing pumping agent. The environment-friendly concrete anti-freezing pumping agent disclosed by the invention is good in anti-freezing pumping effect, high in water reducing rate, low in bleeding rate, high in compressive strength, small in mixing amount and good in performance stability, and concrete using the anti-freezing pumping agent is excellent in comprehensive performance.
本发明公开了一种环保型混凝土防冻泵送剂，其特征在于，包括如下重量份计的各组分：N‑苯基‑3‑烯丙酸甲酯苯磺酰胺/3‑丙烯酰胺基苯硼酸/2‑(5‑苯基‑1H‑四唑‑1‑基)‑3‑噻吩‑2‑丙烯酸/N,N‑二(2‑羟乙基)油胺共聚物8‑12份、聚羧酸高性能减水剂15‑25份、壳聚糖季铵盐2‑4份、硝酸锌1‑2份、异硫脲丙基硫酸盐改性羧甲基纤维素1‑3份、纳米氧化锌2‑4份、水35‑45份。本发明还公开了所述环保型混凝土防冻泵送剂的制备方法。本发明公开的环保型混凝土防冻泵送剂防冻泵送效果好，减水率高，泌水率低，抗压强度大，掺量少，性能稳定性佳，使用该防冻泵送剂的混凝土综合性能优异。
