Polycarboxylate superplasticizer for concrete and preparation method thereof
The invention discloses a polycarboxylate superplasticizer for concrete and a preparation method of the polycarboxylate superplasticizer. The polycarboxylate superplasticizer comprises the following components in parts by weight: 8-40 parts of unsaturated phosphate oligomer; 150 to 250 parts of a polyether macromonomer; 5 to 15 parts of first unsaturated acid; 0.5 to 5 parts of an oxidant; 0.1 to 1 part of a reducing agent; 0.5 to 5 parts of a chain transfer agent; and 162 to 1575 parts of water. Concrete mixed with the polycarboxylate superplasticizer has good fluidity, mud resistance and slump loss resistance.
本发明公开一种用于混凝土的聚羧酸减水剂及其制备方法，包括如下重量份的组分：不饱和磷酸酯低聚物：8～40份；聚醚大单体：150～250份；第一不饱和酸：5～15份；氧化剂：0.5～5份；还原剂：0.1～1份；链转移剂：0.5～5份；水：162～1575份。掺和本发明的聚羧酸减水剂的混凝土具有良好的流动性、抗泥性及保坍性。
