一种新型保坍型聚羧酸减水剂的合成及其应用性能研究
Synthesis and application of a new slump retarding polycarboxylate superplasticizer
摘要
Abstract
Taking polyoxyethylene allyl methyl ether (TPEG ),acrylic acid (AA )and polyglycerol acrylate (PA)as comonomer,under the action of vitamin C (VC ),hydrogen peroxide (H2 O2 )and chain transfer agent thioglycolic acid (TGA),a new slump retarding superplasticizer HS-JG was synthesized. The structure of the product was characterized by using gel chromatography and infrared spectrum,and the study on its application performance was carried out. Results show that when n(AA):n(PA):n(TPEG)=2:0. 15:1,the content of VC ,H2 O2 and TGA is 0. 5％,1. 4％ and 0. 5％ of the mass of TPEG respectively,the reaction temperature is 50 ℃,and the reaction time is 3 h,the synthesized product HS -JG has good adaptability to cement. The slump retarding property is better in ability to maintain for cement paste and concrete.关键词
