摘　　要：采用3种包覆剂对两种可膨胀石墨进行了表面包覆,测试了包覆前后可膨胀石墨的膨胀性能,结果表明包覆剂1对可膨胀石墨的膨胀性能无明显影响,包覆剂2和包覆剂3使可膨胀石墨的膨胀倍率增加。此外,测试了由不同包覆剂处理的可膨胀石墨制备的发烟剂对毫米波的衰减性能,结果表明包覆剂对毫米波衰减性能有一定影响,其中包覆剂2的影响显著。Two different expansible graphites were coated with three different coating substances. The test results of expansion performance of coated expansible graphites show that coating substance 1 has no distinct effect on expansion multiple, and coating substance 2 and 3 increase the expansion multiple. The test results of millimeter wave attenuation of smoke producing agent, which was prepared with coated expansible graphites, show that coating substances have some effect on attenuation performance at millimeter waves, and coating substance 2 has especially distinct effect.
