Adaptive comprehensive liquid polycarboxylate superplasticizer
The invention belongs to the field of water reducing agents, in particular relates to an adaptive comprehensive liquid polycarboxylate superplasticizer, and aims at the problems that the existing water reducing agent is single in function, and anti-freezing and retarding characteristics are poor. The adaptive comprehensive liquid polycarboxylate superplasticizer comprises the following raw materials in parts by weight: 15 to 25 parts of a polycarboxylic acid solution; 10-15 parts of acrylic acid, 1 to 5 parts of sodium methallyl sulfonate; 1-5 parts of an anti-mud type polycarboxylate superplasticizer; 1-5 parts of a slump retaining type polycarboxylate superplasticizer; 1-5 parts of a water-reducing polycarboxylate superplasticizer, 5-10 parts of lignosulfonate, 3-8 parts of sodium alginate, 3-8 parts of ethylene glycol, 1-5 parts of ammonium phosphate, 2-7 parts of alkylamine, 3-7 parts of propylene glycol, 5-10 parts of benzenesulfonyl chloride, 2-8 parts of benzoyl chloride, 6-11 parts of sodium gluconate, 4-9 parts of sodium phosphate and 2-6 parts of sodium citrate. While the water reducing rate is increased, the anti-freezing property and retarding property can be improved,and the preparation method is simple.
本发明属于减水剂领域，尤其是一种适应性综合型液体聚羧酸减水剂，针对现有的减水剂功能单一，抗冻、缓凝特性差的问题，现提出如下方案，其包括以下重量份的原料：聚羧酸溶液15‑25份、丙烯酸10‑15份、甲基丙烯磺酸钠1‑5份、抗泥型聚羧酸减水剂1‑5份、保坍型聚羧酸减水剂1‑5份、减水型聚羧酸减水剂1‑5份、木质素磺酸盐5‑10份、海藻酸钠3‑8份、乙二醇3‑8份、磷酸酯胺盐1‑5份、烷基胺2‑7份、丙二醇3‑7份、苯磺酰氯5‑10份、苯甲酰氯2‑8份、葡萄糖酸钠6‑11份、磷酸钠盐4‑9份、柠檬酸钠2‑6份，本发明在提高减水率的同时，可以可以提高抗冻性能和缓凝特性，制备方法简单。
