摘要
通过差热分析(DSC)研究了环氧树脂/DDM/DOPO-HQ(2-(6H-二苯并<c,e><1,2>-5-氧杂-6-膦酰杂-6-苯基-1,4-对苯二酚)体系的非等温过程固化反应动力学,研究了不同含磷量对固化反应的影响,通过Kissinger法与Crane法计算了固化反应的活化能和反应级数,确定了环氧树脂/DDM/DOPO-HQ的固化工艺条件。结果表明,含磷单体的加入量越大,固化反应的活化能越低,由51.32降低到33.51 kJ.mol-1。确定了固化工艺应为110℃固化1 h,150℃固化4 h,180℃固化1 h。
Curing kinetics of epoxy resin/DDM/DOPO-HQ(2(6-oxido-6H-dibenz(c,e)(1,2)oxa phosphorin-6-yl)-1,4-dihydroxy phenylene)system was studied by different scanning calorimetries(DSC).The effect of different phosphorus contents was discussed.The activation energy of the curing reaction was obtained by Kissinger and Crane method.Curing technology of the epoxy resin/DDM/DOPO-HQ curing system was also determined.It showed that along with the rising of phosphorus contents the activation energy decressed from 51.32 to 33.51 kJ·mol^(-1).Solidification could be obtained under the condition that when temperature was 110 ℃ for one hour;150 ℃,four hours;180 ℃,one hour.
