Environment-friendly composite anti-freezing pumping agent and preparation method thereof
The invention discloses an environment-friendly composite anti-freezing pumping agent. The pumping agent is prepared from the following components in parts by weight: 10 to 15 parts of acid-based ester group co-grafted 3, 4-ethylenedioxy thiophene-2, 5-dicarboxylic acid/amidinothiourea condensate, 20 to 30 parts of a polycarboxylic acid high-performance water reducing agent, 3 to 5 parts of hyperbranched polyglycidol, 1 to 2 parts of tannic acid and 0.5 to 1.5 parts of S-adenosylmethionine butanedisulfonate. The invention further discloses a preparation method of the environment-friendly composite anti-freezing pumping agent. The environment-friendly composite anti-freezing pumping agent disclosed by the invention combines the advantages of an anti-freezing agent and the pumping agent, andis good in anti-freezing effect, good in pumping efficiency, small in crystallization amount at low temperature, high in cohesive force, relatively small in slump loss, free of pollution and excellent in water reducing performance, and concrete using the anti-freezing pumping agent is good in comprehensive performance, high in compressive strength and good in durability.
本发明公开了一种环保复合型防冻泵送剂，其特征在于，包括如下重量份计的各组分：酸基酯基共接枝3,4‑乙撑二氧基噻吩‑2,5‑二羧酸/脒基硫脲缩合物10‑15份、聚羧酸高性能减水剂20‑30份、超支化聚缩水甘油3‑5份、单宁酸1‑2份、S‑腺苷蛋氨酸丁二磺酸盐0.5‑1.5份。本发明还公开了所述环保复合型防冻泵送剂的制备方法。本发明公开的环保复合型防冻泵送剂结合了防冻剂和泵送剂的优点，防冻效果好、泵送效率佳，在低温时的析晶量小、粘聚力高、坍落度损失较小且无污染，减水性能优异，使用该防冻泵送剂的混凝土综合性能佳、抗压强度大、耐用性好。
