Early-strength polycarboxylate superplasticizer and preparation method thereof
The invention discloses an early-strength polycarboxylate superplasticizer and a preparation method thereof. The early-strength polycarboxylate superplasticizer comprises an unsaturated polyether monomer, an unsaturated carboxylic acid monomer, a functional monomer 1, a functional monomer 2, a cation-containing functional monomer, an oxidizing agent, a chain transfer agent and a reducing agent. Wherein the functional monomer 1 is a compound containing an amide group, and the functional monomer 2 is a compound containing a boric acid group and a diethanol amine group at the same time. According to the early strength type polycarboxylate superplasticizer, the functional monomer 1, the functional monomer 2 and the cation-containing functional monomer are added, so that the formed early strength type polycarboxylate superplasticizer has better early strength.
本发明公开了一种早强型聚羧酸减水剂及其制备方法，该早强型聚羧酸减水剂包括：不饱和聚醚单体、不饱和羧酸单体、功能单体1、功能单体2、含阳离子功能单体、氧化剂、链转移剂和还原剂；其中，功能单体1为含酰胺基团的化合物，功能单体2为同时含有硼酸基团和二乙醇胺基团的化合物。本发明中的早强型聚羧酸减水剂通过加入功能单体1、功能单体2以及含阳离子功能单体，促使形成的早强型聚羧酸减水剂具有较好的早期强度。
