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

YI TUMING

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，包括底层、中层和面层。本发明中，利用耐高温有机硅防腐蚀涂料涂层、中层和面层作为涂层的原料，其中，中层为由γ‑(2，3‑环氧丙氧基)丙基三甲氧基硅烷作为有机成分、纳米二氧化硅及纳米二氧化硅溶胶作为无机交联剂合成的具有网状结构的耐高温涂料，提高涂层的隔热保温效果，设置的面层能够起到良好的耐高温、抗辐射、防水防潮效果，适宜推广使用。
