Concrete retarding and water reducing agent and preparation method thereof
The invention discloses a concrete retarding and water reducing agent which comprises the following components: polycarboxylic acid water reducing agent mother liquor, polymerized zirconium chloride, aromatic polyamide fiber and ferric sulfate. The invention also discloses a preparation method of the retarding and water reducing agent, which comprises the following steps: adding ionized water, polymerized zirconium chloride, sodium polyaspartate and coco fatty acid diethanol amide according to a specific proportion to form modified polymerized zirconium chloride, and then adding other additives. The concrete retarding and water reducing agent is prepared from a mixed solution of an initiator, a polycarboxylic acid water reducing agent mother liquor, aromatic polyamide fibers, ferric sulfate, an initiator and a chain transfer agent, the concrete retarding and water reducing agent is finally obtained, the setting time of concrete is adjusted, and the concrete retarding and water reducing agent has the advantages of high strength and durability. And the slump loss of the concrete can be slowed down, and the adaptability and environmental protection of the product are improved.
本发明公开了一种混凝土缓凝减水剂，包括如下组分：聚羧酸减水剂母液、聚合氯化锆、芳香聚酰胺纤维、硫酸铁。本发明还公开该缓凝减水剂的制备方法，其通过特定比例的添加离子水、聚合氯化锆、聚天冬氨酸钠、椰油酸二乙醇酰胺形成改性聚合氯化锆，然后加入其他添加剂。提高混凝土缓凝减水剂的密实程度、并节约水泥、改善混凝土工作性能，提高混凝土的强度和耐久性，通过引发剂、聚羧酸减水剂母液、芳香聚酰胺纤维、硫酸铁、引发剂和链转移剂的混合溶液，最终得到混凝土缓凝减水剂，调整混凝土的凝结时间，还可以减缓混凝土的坍落度损失，提高产品的适应性和绿色环保的特点。
