首先研究了PT/BADCy二元树脂体系的力学性能和耐热性能,结果表明:BADCy的加入可以改善PT树脂韧性,体系中PT树脂比例越高,灼烧后混合树脂的残留率越高。还重点研究了PT/BADCy/PASF三元树脂体系,力学分析表明:PASF的加入,大大提高了体系的韧性,当含量为10%wt时,常温、200℃以及300℃剪切强度分别为20.88、22.78、14.36MPa,90°常温剥离强度为26.89N/cm。热学分析表明:不同含量PASF的三元树脂体系的热降解趋势基本一致,高温灼烧后残留率大致相同。PASF树脂的耐热性、耐灼烧型与PT/BADCy相当,三者可以实现理想匹配。
Firstly, the mechanical properties and heat resistance of PT / BADCy binary resin system were studied. The results show that the addition of BADCy can improve the toughness of PT resin. The higher the proportion of PT resin in the system, the higher the residual resin content after burning. The PT / BADCy / PASF ternary resin system was also studied emphatically. The mechanical analysis showed that the addition of PASF greatly enhanced the toughness of the system. When the content was 10% wt, the shear strength at room temperature, 200 ℃ and 300 ℃ were 20.88 , 22.78,14.36MPa, 90 ° peel strength at room temperature was 26.89N / cm. Thermal analysis shows that the thermal degradation trends of ternary resin systems with different contents of PASF are basically the same, and the residual rates after burning at high temperature are almost the same. PASF resin heat resistance, burning type and PT / BADCy quite, the three can be an ideal match.
