摘要:
为了研究超临界二氧化硅/聚醚砜/二烯丙基双酚 A/双酚 A 双烯丙基醚/双马来酰亚胺(SCE-SiO 2 /PES/BBA/BBE/MBMI)复合材料的固化动力学和耐热性(BBA/BBE/MBMI 以 MBAE表示)。利用 SEM 观察材料断面形貌;利用非等温 DSC(差示扫描量热)法,研究复合材料的非等温固化动力学;利用热失重分析法(TGA)分析不同 SiO 2 含量对材料耐热性影响。结果表明:当SCE-SiO 2 和 PES 含量适当时,在基体中分散均匀,且断面呈现韧性断裂;根据 Kissinger 方程和 Oza-wa 方程计算出复合材料的表观活化能分别为92. 78 kJ/mol 和96. 65 kJ/mol,再利用 Crane 方程和 n级动力学模型计算出固化动力学方程为:dα/dt =4. 77 ×10 8 (1 - α) 0. 91 e ( -11. 39/T) ,确定了固化工艺当 SCE-SiO 2 质量分数为 2%,PES 质量分数为 5% 时,复合材料的热稳定性最好,热分解温度为445. 63℃,比掺杂前提高了 5. 8℃
Abstract:
In order to study curing kinetics and heat resistance of supercritical silica(SCE-SiO 2 ) / polyether sulfone(PES) /diallyl bisphenol A(BBA) /bisphenol A diallyl oxide(BBE) /bismaleimide(MBMI),(BBA BBE/MBMI expressed in MBAE). The micro morphology of the fracture surface was observed by SEM. Non-isothermal curing kinetics of reaction process was studied with Differential Scanning Calorimetry (DSC). The content of SCE-SiO 2 influenced on the heat resistance of composites by thermal gravimetric analysis (TGA) . The results showed that PES and SCE-SiO 2 uniformly dispersed in matrix,when the SCE-SiO 2 content and PES were appropriate,and its cross section exhibited ductile fracture,the apparent activation energy of composities were 92. 78 kJ/mol and 96. 65 kJ/mol according to Kissinger and Ozawa equations,respectively. The curing kinetics equation was dα/dt =4. 77 ×10 8 (1 - α) 0. 91 e ( -11. 39/T) by Crane equation and the n-order kinetic model. When the content of SCE-SiO 2 was 2%,PES content was 5%,the thermal stability of composites was preferably,the thermal decomposition temperature was 445. 63℃ and improved 5. 8℃ than that of undoped material.
