摘　　要：以氧化锌作固化剂,二氧化硅作填料,混合磷酸铬铝制备铬基透波材料基体。通过DSC-TG测试得出该基体的固化温度范围,根据测试结果在不同温度点、不同时间条件下进行固化实验。分析SEM,XRD,IR测试结果得出在180℃/2h条件下该材料体系能完成交联固化反应,并结合电性能测试分析验证了该结论。最后得出该铬基透波材料基体的最佳固化温度和最佳固化时间分别为180℃和2h。Using zinc oxide as curing agent and silicon dioxide as filler, mixed with chrome-alumina phosphate, the matrix of chromium based wave-transparent materials were prepared. The curing temperature range of matrix was obtained by DSC-TG testing. Based on the DSC-TG analysis, the electrical properties under different temperature points were investigated companied with SEM, XRD and IR analyses. Finally, the best curing condition of the chromium based wave-transparent materials was obtained as that the temperature is 180℃ and the time is 2h.
