    含Zr聚乙炔基苯胺树脂的制备

    Synthesis of Zirconium Aminophenylacetylene Resin

    • 摘要: 以四氯化锆、苯乙炔和间乙炔基苯胺(APA)为原料,通过先驱体合成法制备新型含锆有机先驱体树脂——含Zr聚乙炔基苯胺树脂(ZAPA)。通过FT-IR表征了其结构,利用DSC及FT-IR研究了其固化反应,通过TG研究了其固化物的耐热性能,采用XRD和EDS研究了其固化物的烧结性能。结果表明:ZAPA树脂可以发生固化交联反应,其固化物相对于APA的固化物具有更好的耐热性能,在N2气氛下,ZAPA树脂固化物失重5%的温度为445 °C,1 000 °C下的质量残余率为43.7%;在空气气氛中,1 000 °C下烧结5 h后,可形成ZrO2晶体。

       

      Abstract: A new kind of zirconium aminophenylacetylene (ZAPA) resin was synthesized using 3-aminophenylacetylene (APA), acetylene and zirconium tetrachloride as materials through precursor synthesis. The structures were characterized by FT IR. Thermal curing reaction was monitored by DSC and FT-IR. Thermal properties of cured ZAPA were evaluated by TG analysis. Moreover, the ceramic properties of cured ZAPA were studied by XRD and EDS analysis. Results showed that the ZAPA resin could be cured. Compared with the cured APA, the cured ZAPA resins had better thermal stability. The temperature of 5% mass loss under nitrogen was up to 445 °C and the residual at 1 000 °C was 43.7%. In the air, α ZrO2 containing ceramic was obtained after sintering at 1 000 °C for 5 h.
