以硝酸铟、乙酸铜作为原料，水为溶剂，其中硝酸铟与乙酸铜的摩尔比为1:1，将硝酸铟、乙酸铜与水均匀混合后置于反应容器内并密封，于温度120-200℃、保温12-48h，其中硝酸铟与乙酸铜的重量不大于水重量的50％。
本发明所提供的铟酸铜纳米线复合高温密封胶的具体制备方法如下：
按照质量比例称取铟酸铜纳米线、氧化聚乙烯蜡乳液、呋喃树脂和有机硅乳液，然后将氧化聚乙烯蜡乳液、呋喃树脂和有机硅乳液混合，接着加入铟酸铜纳米线，机械搅拌4-8小时混合均匀，最终得到了铟酸铜纳米线复合高温密封胶。
与现有技术相比，本发明具有以下技术效果：
1、本发明以耐高温的铟酸铜纳米线作为填料，氧化聚乙烯蜡乳液、呋喃树脂作为胶粘剂，有机硅乳液作为防水剂，可以制备出铟酸铜纳米线复合高温密封胶。这种密封胶具有良好的密封性、耐高温、耐腐蚀、耐老化、热稳定、阻燃及耐水性能，在材料、化工、机械等高温、腐蚀性介质的容器、阀门和管道密封方面具有良好的应用前景。
2、本发明采用的铟酸铜纳米线熔点高、耐腐蚀性强、稳定性好和无污染，所用原料都可以批量生产，可以实现铟酸铜纳米线复合高温密封胶的批量制备。
