摘 要:以對氨基苯磺酸、苯酚、甲醛為主要原料,合成了氨基磺酸系減水劑,研究了氨基磺酸系減水劑的合成工藝路線(xiàn)及原料配比、原料濃度、反應pH值、反應溫度等因素對減水效果的影響,驗證了優(yōu)化工藝條件下聚合產(chǎn)物的重復性及擴大性,并用紅外光譜對聚合產(chǎn)物的結構進(jìn)行了分析與表征。優(yōu)化的反應條件為:n(對氨基苯磺酸)∶n(苯酚)∶n(甲醛)=1∶2∶6、反應初始pH值為8、氨基苯磺酸的濃度為0.4 mol/L、反應溫度為90~95℃時(shí)。
關(guān)鍵詞:氨基磺酸系;高效減水劑;減水性能

The Synthesis and Properties of Additives for Aluminum Oxides Ceramics
SUN Qi-juan, LU Yin, LUO Jin-chao (Shanxi Polytechnic Institute, Xianyang 712000, China)
Abstract:A series of thionamic water reducing reagents(HRWRA)were prepared using sulfanilic acid, the phenol, and the formaldehyde as the main raw materials. The process for the synthesis of amino acids superplasticizer was investigated. The influence of molar ratio of momomers, concentration of raw materials, acidity in the reaction system, reaction temperature on the properties of the final product was also evaluated. Furthermore, the repeatability and scale-up experiment of this polymerization product under optimum conditions were also tested. The polymerized product structure was characterized using IR. The optimum experimental conditions were as following∶Sulfanilic acid∶Pheno∶Formaldehyde=1∶2∶6; initial pH value, 8; aminobenzenesulfonic acid density, 0.4mol/L, reaction temperature, 90~95℃.
Key words:thionamic acid series; HRWRA; the water reducing performance
