摘要
以丙烯酸(AA)极性单体与石蜡接枝得到的丙烯酸接枝石蜡与酰胺反应生成酰化的接枝石蜡。用红外光谱仪和差示扫描量热仪对酰化的丙烯酸接枝石蜡的结构和热性能进行了分析。与未改性石蜡相比,酰化的丙烯酸接枝石蜡相变温度提高了16.3%,相变潜热提高了59.07%,在三种改性石蜡中酰化的丙烯酸接枝石蜡相变温度最高,相变潜热最大。分析三种改性石蜡的分子结构与其相变温度相变潜热的关系。
The Acylation reaction of Paraffin graft Acrylic acid with aniline was carried out using the catalyst of Zn. The structure and the thermal property of the acylate were characterized by IR and DSC respectively. Modified paraffin＇s phase change temperature was widened by 16.3% successfully, and its latent heat was improved by 59.07% compared to paraffin. Of the three modified paraffins（paraffin-g-AA, paraffin-g-MMA, acylate of paraffin graft acrylic acid）, acylate＇s phase change temperature/latent heat is the best. The relation of paraffin＇s phase change temperature/latent heat and its molecule structure was summarized.
