Polycarboxylic acid water reducing agent and production process thereof
The invention discloses a polycarboxylic acid water reducing agent and a preparation method thereof, and the water reducing agent comprises the following substances in parts by weight: 100-150 parts of unsaturated polyoxyethylene ether, 10-15 parts of unsaturated carboxylic acid, 4-8 parts of sodium methallyl sulfonate, 2-5 parts of dibenzoyl peroxide, 1-5 parts of an astragalus extract, 1-8 parts of fluconazole, 1-5 parts of ferrous sulfate and 100-150 parts of water. The unsaturated polyoxyethylene ether, the unsaturated carboxylic acid, the sodium methallyl sulfonate, the dibenzoyl peroxide, the astragalus extract, the fluconazole, the ferrous sulfate and other substances are mixed, so that the yield of the obtained olycarboxylic acid water reducing agent is high in the free radical copolymerization reaction of the unsaturated polyoxyethylene ether and the unsaturated carboxylic acid, meanwhile, the addition of water is reduced, and the solid content is greatly improved.
本发明公开了一种聚羧酸减水剂及其制备方法，所述减水剂按重量份数包括以下物质：不饱和聚氧乙烯醚100‑150份、不饱和羧酸10‑15份、甲基丙烯磺酸钠4‑8份、过氧化二苯甲酰2‑5份、黄芪提取物1‑5份、氟康唑1‑8份、硫酸亚铁1‑5份及100‑150份水，本发明通过将不饱和聚氧乙烯醚、不饱和羧酸、甲基丙烯磺酸钠、过氧化二苯甲酰、黄芪提取物、氟康唑、硫酸亚铁等物质混合，在保证在不饱和聚氧乙烯醚与不饱和羧酸自由基共聚反应中，得到的聚羧酸减水剂产率高，同时减少水的添加，具备固含量大幅提升。
