Polycarboxylate superplasticizer and preparation method thereof
The invention discloses a polycarboxylate superplasticizer and a preparation method thereof. The polycarboxylate superplasticizer is prepared from the following components in parts by weight: 30 parts of hollow porous nano silicon oxide, 100 parts of polyethylene glycol monomethyl ether, 20 parts of unsaturated monomer, 4 parts of initiator, 1 part of reducing agent, 3-4 parts of chain transfer agent and 100 parts of deionized water. By adding the porous nano silicon oxide, the polycarboxylic acid water reducing agent has excellent slow release performance, the duration time of the water reducing agent is greatly prolonged, and the popularization and application of the product are improved.
本发明公开了一种聚羧酸减水剂及其制备方法，采用包括如下重量份数的各组分制备而成：包括空心多孔纳米氧化硅30份、聚乙二醇单甲醚100份、不饱和单体20份、引发剂4份、还原剂1份、链转移剂3～4份、去离子水100份。本发明通过添加多孔纳米氧化硅，使得聚羧酸减水剂具有优异的缓释性能大大提高减水剂持续时间，提高了该类产品的推广应用。
