摘　　要：介绍了一种H61-1铝粉环氧有机硅耐热面漆和配套的H61-83环氧有机硅耐热底漆在与飞机发动机尾气相连接的某零件上的应用。通过加热法、划格法以及冲击法对该漆层进行了耐热性、结合力和冲击强度的测试。结果表明,这种漆层具有良好的耐热性、结合力和耐冲击性能。将这种漆层应用于与飞机发动机尾气相连接的零件上,零件可长时间承受发动机尾气对漆层的影响,避免漆层的老化、脱落,使零件的防腐能力和使用寿命得到提高。The application of a kind of H61-1 aluminum epoxy silicone heat resistant topcoat and a matching H61-83 epoxy silicone heat resistant primer on the part connected with the tail gas of aircraft engine was introduced in this paper.The heat resistance,bonding force and impact strength of the coatings were tested by heating method,grid method and impact method.The results show that the coating system has good heat resistance,bonding force and impact resistance.Applying this coating system to parts connected with the exhaust of the aircraft engine can withstand the impact of engine exhaust on the paint layer for a long time,avoiding aging and peeling of the paint layer,and improving the anticorrosion ability and service life of the parts.
