摘　　要：以三元乙丙橡胶(EPDM)和三元乙丙橡胶接枝马来酸酐(EPDM-g-MAH)为粘结剂,并分别添加不同含量的铜粉填料,制得具有不同发射率的红外涂层,对粘结剂的红外光谱、涂层中粘结剂与颜料的界面及涂层的发射率、微观形貌等方面进行了分析。结果表明,EPDM经接枝改性后,红外透明性基本不变;XPS分析表明EPDM-g-MAH中的极性基团可与金属材料形成配位键,增强了粘结剂与金属颜料间的相容性,降低了涂层的红外发射率。并着重对其原因进行了分析。Through adding Cu powder in EPDM and EPDM-g-MAH which used as adhesive,infrared coatings with different infrared emissivity(8～14μm) were obtained.The infrared spectra of the adhesive,the interface between adhesion and pigment,the emissivity and microcosmic configuration of the coatings were analyzed.The results showed that,infrared transparency was essentially the same after graft modification of EPDM.The XPS analysis showed that the polar groups of EPDM-g-MAH could form coordination bonds with the metal,significantly improve the compatibility between adhesive and metallic pigment and the emissivity of coatings was decreasing.The reasons were analyzed in detail.
