Powdery polycarboxylic acid high-performance water reducing agent and preparation method thereof
The invention discloses a powdery polycarboxylic acid high-performance water reducing agent and a preparation method thereof. The environment-friendly concrete additive comprises the following raw materials in parts by weight: 10-20 parts of methacrylic acid, 5-10 parts of a vitamin C water solution, 10-20 parts of asparagine, 5-10 parts of an ammonium persulfate water solution, 10-20 parts of butanol, 5-10 parts of methyl allyl polyoxyethylene ether, 3-5 parts of ferrous sulfate, 1-3 parts of an active protective agent, 1-2 parts of a retarder, 0.5-1 part of a viscosity modifier, 1-2 parts of a thixotropic agent, 0.5-1 part of an air entraining agent, 1-2 parts of a foam stabilizer and 20-40 parts of water. The invention relates to the technical field of building materials. According to the powdery polycarboxylic acid high-performance water reducing agent and the preparation method thereof, the water reducing agent can be directly crushed, ground and secondarily screened, so that the produced water reducing agent powder can well meet the use requirements, the purpose of quickly and efficiently fully pulverizing the water reducing agent is well achieved, the crushing is thorough, multiple times of crushing is not needed, and the production cost is reduced. And the workload of production personnel is greatly reduced, and the production efficiency is improved.
本发明公开了一种粉状聚羧酸高性能减水剂及其制备方法，其原料按重量份包括：甲基丙烯酸10‑20份、维生素C水溶5‑10份液、天冬酰胺10‑20份、过硫酸铵水溶液5‑10份、丁醇10‑20份、甲基烯丙基聚氧乙烯醚5‑10份、硫酸亚铁3‑5份、活性保护剂1‑3份、缓凝剂1‑2份、粘度调节剂0.5‑1份、触变剂1‑2份、引气剂0.5‑1份、稳泡剂1‑2份和水20‑40份，本发明涉及建筑材料技术领域。该粉状聚羧酸高性能减水剂及其制备方法，可实现通过对减水剂直接进行粉碎、研磨和二次筛选，来确保生产的减水剂粉料能够很好的达到使用要求，很好的达到了既快速有高效的对减水剂进行充分造粉的目的，粉碎彻底，无需多次粉碎，大大减轻了生产人员的工作负担，提高了生产效率。
