新型耐高温氰酸酯/磷酸铝复合材料的研究

Study on Novel Heat Resistant Cyanate Ester/phosphate Aluminum Composite

基于氰酸酯树脂(CE)和磷酸铝(AlPO4)优良的综合性能,采用"复合技术",设计并制备了AlPO4/CE复合材料,研究了不同偶联剂和AlPO4含量对AlPO4/CE复合材料的热性能、介电性能和吸湿性能的影响。研究结果表明,不同偶联剂对磷酸铝和CE之间的界面作用力影响不同。AlPO4(KH-550)和AlPO4(KH-560)与CE间的界面作用力稍高于AlPO4(H-2),并且AlPO4(KH-550)/CE复合材料的综合性能最佳;当加入适当含量AlPO4(KH-550)时,AlPO4(KH-550)/CE复合材料具有比纯CE树脂更佳的综合性能。

Based on the outstanding integrate properties of both cyanate ester （CE） and phosphate aluminum （AlPO4 ） , AlPO4/CE composites were designed and prepared in this work by employing the ＂composite technology＂. The effects of the coupling agent type and AlPO4 content on the properties of the new composites are discussed. Results show that different coupling agents have different effects on the interracial adhesion between AlPO4 and CE. AlPO4 （KH-550） and AlPO4 （KH-560） have stronger interfacial effects than AlPO4（H-2）, and AlPO4 （KH-550）/CE has the optimum properties among the three composites. Moreover, AlPO4 （KH-550）/CE composite with desirable AlPO4 （KH-550） content has better properties than CE resin.
