锆炔杂化树脂的制备及性能

Synthesis and Properties of Zirconium-Acetylene Hybrid Resin

摘要: 以四氯化锆、三氯乙烯及苯乙炔为原料，通过有机锂法合成锆炔杂化树脂（PZA），通过FT-IR、1H-NMR表征了其结构，利用FT-IR、DSC及TGA研究了PZA树脂的固化反应及耐热性能；采用XRD研究了PZA树脂固化物的烧结性能。结果表明：PZA树脂可以发生固化交联反应；其固化物具有一定的耐热性能，在氮气气氛中，失重10%的温度（Td10）达到500 °C，1 000 °C下的质量保留率达到80%；在空气气氛中，1 000 °C下烧结可形成四方氧化锆陶瓷。

Abstract: A new kind of zirconium-acetylene hybrid resin was synthesized from trichloroethylene, phenylacetylene and zirconium tetrachloride using organolithium method. The structures of resin were characterized by FT-IR and 1H-NMR. Thermal curing process was monitored by DSC and FT-IR. Thermal and oxidative properties were evaluated by TGA analysis. Results showed the PZA resin can cure. The cured PZA resins had good thermal stability, the temperature of 10% mass loss (Td10) under nitrogen was up to 500 °C and the residual at 1 000 °C was 80%. α-ZrO2-containing ceramic was obtained after sintering at 1 000 °C.
