Preparation method of waterproof high-temperature-resistant coating of military electronic equipment

The invention relates to the technical field of functional materials, in particular to a preparation method of a waterproof high-temperature-resistant coating for military electronic equipment, whichcomprises a bottom layer, a middle layer and a surface layer. According to the invention, a high-temperature-resistant organic silicon anticorrosive paint coating, a middle layer and a surface layer are used as raw materials of the coating, the middle layer is a high-temperature-resistant paint with a reticular structure, which is synthesized by taking gamma-(2, 3-epoxypropoxy)propyltrimethoxysilane as an organic component and taking nano silicon dioxide and nano silicon dioxide sol as inorganic cross-linking agents, the thermal insulation effect of the coating is improved, and the arranged surface layer can achieve good high-temperature-resistant, radiation-resistant, waterproof and moistureproof effects, so that the coating is suitable for popularization and application. 本发明涉及功能材料技术领域，尤其为一种军用电子设备防水耐高温涂层的制备方法，包括底
