Triethylene glycol divinyl ether cross-linked polycarboxylate superplasticizer and application thereof
The invention aims to provide a triethylene glycol divinyl ether cross-linking type polycarboxylic acid water reducing agent and application of the triethylene glycol divinyl ether cross-linking type polycarboxylic acid water reducing agent. The triethylene glycol divinyl ether crosslinking type polycarboxylic acid water reducing agent is prepared from the following raw materials: an unsaturated polyoxyethylene ether monomer, modified nano inorganic powder, triethylene glycol divinyl ether, an unsaturated carboxylic acid monomer, an initiator and a chain transfer agent. The unsaturated polyoxyethylene ether monomer, the modified nano inorganic powder, the triethylene glycol divinyl ether, the unsaturated carboxylic acid monomer, the initiator and the chain transfer agent are subjected to free radical polymerization reaction to obtain the triethylene glycol divinyl ether cross-linked polycarboxylic acid water reducer. According to the preparation method, free radical polymerization reaction is adopted, modified nano powder and triethylene glycol divinyl ether are introduced, the micro-crosslinking functional polycarboxylic acid water reducing agent is synthesized, the problem that no applicable polycarboxylic acid water reducing agent exists in fly ash-based geopolymer cement at present is solved, the preparation process is green and environment-friendly, energy is saved, and the environmental benefit is obvious.
本发明旨在提供一种三乙二醇二乙烯基醚交联型聚羧酸减水剂及应用。该三乙二醇二乙烯基醚交联型聚羧酸减水剂，原料包括不饱和聚氧乙烯醚单体、改性纳米无机粉体、三乙二醇二乙烯基醚、不饱和羧酸单体、引发剂和链转移剂。且不饱和聚氧乙烯醚单体、改性纳米无机粉体、三乙二醇二乙烯基醚、不饱和羧酸单体、引发剂和链转移剂之间通过自由基聚合反应后即可获得三乙二醇二乙烯基醚交联型聚羧酸减水剂。本发明采用自由基聚合反应，引入改性纳米粉体和三乙二醇二乙烯基醚，合成微交联功能型聚羧酸减水剂，解决粉煤灰基地聚物水泥目前无适用聚羧酸减水剂的问题，制备过程绿色环保，节能和环境效益明显。
