Environment-friendly non-autoclaved tubular pile water reducing agent and preparation method thereof
The invention discloses an environment-friendly non-autoclaved tubular pile water reducing agent characterized by comprising the following components in parts by weight: 10 to 20 parts of 1,3-bis(oxiranylmethyl)-5-(2-propenyl)-1,3,5-triazine-2,4,6(1H,3H,5H)-trione/4,6-diamino-1,3,5-triazine-2-acetic acid polycondensate, 5 to 10 parts of 7-amino-3-vinyl-3-cephem-4-carboxylic acid/4,4'-diaminostilbene-2,2'-disulfonic acid/polyethylene glycol monoallyl ether/4-vinylphenylboronic acid copolymer, 1 to 3 parts of 9-fluorenecarboxylic acid, 0.3 to 0.6 part of an initiator, 2 to 5 parts of plant polysaccharide and 35 to 45 parts of water. The invention further discloses a preparation method of the environment-friendly non-autoclaved tubular pile water reducing agent. The environment-friendly non-autoclaved tubular pile water reducing agent disclosed by the invention is remarkable in water reducing effect, has the advantages of low dosage, excellent plasticizing performance, no obvious negative influence on the comprehensive performance of concrete, good energy-saving and environment-friendly performance in the preparation and use processes, high reaction activity, low reaction temperatureand capabilities of effectively enhancing the compressive strength, remarkable reduction of the hardening and viscosity of the concrete and improvement of the construction performance of the concrete.
本发明公开了一种环保型免蒸压管桩减水剂，其特征在于，包括如下重量份计的各组分：1,3‑双(环氧乙烷基甲基)‑5‑(2‑丙烯基)‑1,3,5‑三嗪‑2,4,6(1H,3H,5H)‑三酮/4,6‑二氨基‑1,3,5‑三嗪‑2‑乙酸缩聚物10‑20份、7‑氨基‑3‑乙烯基‑3‑头孢环‑4‑羧酸/4,4'‑二氨基二苯乙烯‑2,2'‑二磺酸/聚乙二醇单烯丙基醚/4‑乙烯基苯硼酸共聚物5‑10份、9‑芴甲酸1‑3份、引发剂0.3‑0.6份、植物多糖2‑5份、水35‑45份。本发明还公开了所述环保型免蒸压管桩减水剂的制备方法。本发明公开的环保型免蒸压管桩减水剂减水效果显著，掺量少、增塑性能优异，对混凝土综合性能无明显负面影响，制备和使用过程中节能环保性能好，反应活性高，反应温度低，能有效增强抗压强度，显著降低混凝土的板结和粘度，增加混凝土的施工性能。
