| 摘 要： | 研究了以环氧－聚氨酯互穿聚合物网络（ＥＰ－ＰＵＩＰＮ）为基料，镀银铜粉为导电填料的导电涂料。用扫描式电子显微镜（ＳＥＭ）观察了不同配比ＥＰ－ＰＵＩＰＮ的两相相容性，用差示扫描量热法（ＤＳＣ）测定了ＩＰＮ的玻璃化温度。讨论了ＥＰ－ＰＵＩＰＮ的结构及选择，镀银铜粉的粒度及含量对导电涂料的电阻率和使用性能的影响。试验表明，９０／１０ＥＰ－ＰＵＩＰＮ作为基料，镀银铜粉的含量为８０％、粒度为４００目，涂膜的电阻率低，使用性能好。

| Abstract: | A conductive coatings, based on epoxy-polyurethane IPN(EP-PU IPN) as binder and silver coated bronze powder as conductive pigment, has been developed The compatibility of EP-PU IPN with various compositions is tested by SEM, Tg is measured by DSC The influences of the structure of EP-PU IPN, particle size and amount of silver coated bronze powder on the resistivity and application properties of the conductive coatings were discussed It has shown that 90/10 EP-PU IPN as binder, 80% of silver coated bronze powder with 400 mesh will give a film having lower resistivity and better application properties |
