一、前言环氧树脂固化物具有优异的机械性能、电器绝缘性能和化学稳定性。同时,浇注料配制简便,易于操作,便于成型,这是其它绝缘材料难以相比的,因此,环氧树脂绝缘浇注技术已在电子、机电和国防科学技术上广泛地应用于器件的绝缘,密封、防潮和胶接,大大提高了器件的可靠性能。随着科学技术的不断发展,电子技术正在向组件化方向发展,特别是高压器件的组件化,这是减轻电子设备的重量、向小型化方向发展的必经之路,也是提高电子设备的可靠性、快速应变性能的发展方向。高压器件组件化以后,器件种类多、密集度高、外形结构复杂,这就给环氧浇注技术提出了更高、更新的要求。浇注料的配方要根据器件的 I. Introduction Epoxy resin cured with excellent mechanical properties, electrical insulation and chemical stability. At the same time, pouring material preparation is simple, easy to operate, easy to shape, which is difficult compared to other insulating materials, therefore, epoxy resin casting technology has been widely used in electronic, mechanical and electrical science and technology in the insulation of the device, sealing , Moisture and glue, greatly improving the reliability of the device. With the continuous development of science and technology, electronic technology is developing towards the direction of component, especially the component of high-voltage devices, which is the only way to reduce the weight of electronic devices and to develop towards miniaturization, as well as to improve the reliability of electronic devices Sexual, rapid response properties of the development. After the high-voltage device is assembled, the devices have many types, high density and complex structure, which puts higher and newer requirements for the epoxy pouring technology. Casting formulations according to the device
