中文摘要:
      研究了NR和几种导电性填料复合物的微波屏蔽效果以及填料的用量、电导率和试样厚度对微波屏蔽效果的影响。结果表明，NR/石墨粉复合物对微波屏蔽效果较好，当石墨粉用量为250份时，微波屏蔽效果达42 dB；复合材料的电导率大，微波屏蔽效果就好；当试样厚度为0.35 mm时，微波屏蔽效果达到该体系复合物的极限值(34 dB)；石墨粉在NR中的分散越均匀，复合物的微波屏蔽效果越好。
英文摘要:
      The effect of the conductive filler type，loading level and conductivity and the shield thickness on the effectiveness of microwave shielding was investigated.The results showed that NR/ground graphite composite was a better shielding material and 42 dB of microwave shielding ef fectiveness was obtained with 250 phr of ground graphite in the composite；the higher conductivity of the composite，the better effectiveness of microwave shielding；34 dB of upper limit microwave shielding ef fectiveness was obtained with 0.35 mm of shield thickness；and the more uniform dispersion of ground graphite in the composite，the better microwave shielding effectiveness.
