摘要
通过溶胶-凝胶法制备有机-无机杂化树脂体系,按配方比例加入高红外发射率颜填料研磨色浆、硅烷偶联剂、固化剂得到耐高温高红外发射率涂料。采用喷涂涂装于钛合金表面,70~90℃固化温度固化2 h后涂层红外发射率在8~14μm最高可达0.980。在600℃煅烧2 500 s后涂层外观无明显变化涂层完整,机械性能良好红外发射率为0.852,有效地保护了钛合金底材,使其能够在高温环境下具有良好的热稳定性。
The organic-inorganic hybrid resin system was prepared by sol-gel method. The high temperature and high infrared emissivity coating was prepared by adding high emissivity pigment, silane coupling agent and curing agent. Spray coating on the surface of titanium alloy, and cured at 70 - 90 ℃ for 2 h. The infrared emissivity of the coating was up to 0.980 in the range of 8 - 14 μm. After calcinations at 600 ℃ for 2 500 s, the appearance of the coating remained intact, and the mechanical properties of the coating were excellent. The infrared emissivity of the coating was 0.852. The titanium alloy substrate was protected by this coating, so that it had good thermal stability in high temperature environment.
