Normal-temperature six-carbon polycarboxylate superplasticizer and preparation method thereof
The invention discloses a normal-temperature six-carbon polycarboxylic acid water reducing agent and a preparation method thereof. The normal-temperature six-carbon polycarboxylic acid water reducing agent comprises the following components in parts by weight: 400-500 parts of a monomer, 300-400 parts of water, 15-25 parts of a reaction type auxiliary agent, 1-5 parts of hydrogen peroxide, 0.5-1 part of ammonium persulfate and 0.5-1 part of 1% ferrous liquid. The polycarboxylate superplasticizer is synthesized from the six-carbon monomer at normal temperature, the water consumption of concrete can be reduced in the use process, the use durability of the concrete is improved, the slump loss resistance is improved, the properties of the concrete are changed, the strength is improved, the preparation method is simple, the polycarboxylate superplasticizer can be synthesized at normal temperature, the water reducing rate is increased, and the engineering quality of the concrete is guaranteed.
本发明公开了一种常温六碳聚羧酸减水剂及其制备方法，各成分按重量比为：单体400～500份、水300～400份、反应型助剂15～25份、双氧水1～5份、过硫酸铵0.5～1份、1%的亚铁液0.5～1份；本发明通过六碳单体在常温下合成聚羧酸减水剂，可以使混凝土在使用过程中减少其用水量，并提高其使用耐久性，提高保坍性，改变混凝土性质，提高强度，本发明制备方法简单，在常温下即可合成，提高了减水率，并保证混凝土的工程质量。
