Composite preservative for polycarboxylate superplasticizer and preparation method of composite preservative
The invention relates to the technical field of concrete admixtures, in particular to a compound preservative for a polycarboxylate superplasticizer and a preparation method of the compound preservative. The composite preservative for the polycarboxylate superplasticizer comprises the following raw materials: a first monomer, a second monomer, a synergist and a solvent. The compound preservative for the polycarboxylate superplasticizer, provided by the embodiment of the invention, has a relatively strong algae killing function, can kill phycomycetes caused by unclean pipelines and storage tanks and production water, and also has the advantages of relatively good sterilization performance, high efficiency, broad spectrum and the like.
本发明涉及混凝土外加剂技术领域，特别涉及一种聚羧酸减水剂用复合防腐剂及其制备方法。其中，一种聚羧酸减水剂用复合防腐剂，原料包括第一单体、第二单体、增效剂及溶剂。本发明实施例提供的聚羧酸减水剂用复合防腐剂有较强的灭藻功能，可针对管道储罐不净及生产用水带来的藻菌进行灭杀，同时也具有较佳的杀菌性能及高效广谱等优点。
