考察了甲基丙烯酸羟乙酯/丙烯酸甲酯接枝聚合炭黑的适宜制备条件和影响因素。通过红外光谱(FT-IR)、热失重分析(TGA)考察了接枝炭黑的表面结构和接枝情况,研究了接枝炭黑在水溶液中的吸光度。结果表明:用丙烯酸甲酯/甲基丙烯酸羟乙酯接枝改性后的炭黑在水溶液中具有良好的分散稳定性。 The suitable preparation conditions and influencing factors of hydroxyethyl methacrylate / methyl acrylate grafted polymeric carbon were investigated. The surface structure and grafting of grafted carbon black were investigated by FT-IR and TGA, and the absorbance of grafted carbon black in aqueous solution was investigated. The results show that the carbon black modified with methyl acrylate / hydroxyethyl methacrylate has good dispersion stability in aqueous solution.
