| 摘 要： | 利用差示扫描量热(DSC)法分析了甲醛、苯酚物质的量之比为1.9:1、1.7:1、1.5:1、1.3:1时酚醛树脂(PF)的固化性能,采用Kissinger法计算了4批PF固化反应的表观活化能。用热失重分析(TG)法对4批PF的耐热性能进行了考察。试验结果表明,甲醛、苯酚物质的量之比为1.7:1时,PF的固化反应活化能最低,即固化时需要较少的热量,易固化,其耐热性能最好。

| Abstract: | The curing properties of phenolic resins which had different ratio of substance amount of phenol to formaldehyde were analysed by using DSC method.Apparent energies of curing reaction of four phenolic resins were calculated according to Kissinger method.The heat resistance of four phenolic resins were researched by using TG method.Experiment results showed that when the ratio of substance amount of phenol to formaldehyde was 1.7:1,the curing reaction energy of phenolic resin was the lowest,it cured easily and its heat resistance was the best. |
