一种耐高压绝缘材料的制备方法
摘要：
本发明公开了一种耐高压绝缘材料的制备方法，属于绝缘材料制备技术领域。该方法将白云母和硝酸溶液混合搅拌除杂，通过高温煅烧活化，制得预处理白云母颗粒，随后将预处理白云母颗粒、硝酸铵溶液等物质，在超声下预混，在氮气环境下，以镁条燃烧放热，反应出料，收集的出料物进行冷冻处理随后升温进行过滤，收集滤渣在马弗炉中反应，制得的耐高压绝缘材料基料与聚乙烯、对苯二胺及过氧化苯甲酰进行混炼、压制处理，即可得耐高压绝缘材料，该发明制备的绝缘材料性能稳定，能在超高压情况下使用，且不会出现表面闪络现象，具有优异的绝缘性能，能够承受极高的工作温度，具有广阔市场前景。
摘要（英）：

The invention discloses a preparation method of a high pressure resistant insulating material and belongs to the technical field of insulating material preparation. The preparation method comprises mixing white mica and a nitric acid solution, removing impurities of the mixture, carrying out high temperature calcining activation to obtain pretreated white mica particles, pre-mixing the pretreated white mica particles and an ammonium nitrate solution under ultrasonic action, burning a magnesium strip to release heat in a nitrogen environment, carrying out reaction and discharge, freezing the collected discharged materials, heating the materials, carrying out filtration, collecting the filter residues, carrying out a reaction process on the filter residues in a muffle furnace to obtain a high pressure resistant insulating material base, mixing the high pressure resistant insulating material base, polyethylene, p-phenylenediamine and benzoperoxide, and compressing the mixture to obtain the high pressure resistant insulating material. The high pressure resistant insulating material has stable performances, can be used under superhigh pressure, does not produce surface flashover, has excellent insulating properties, can bear a very high work temperature and has a wide market prospect.
