In order to detect abnormal heat generation in time, a reversible color-changing coating temperature measurement method is proposed for self-detection of temperature by power equipment, and its adhesion characteristics and aging performance were analyzed. The results showed that the reversible color-changing coating prepared with crystalline violet lactone as the colorant, bisphenol A as the color developer, octadecanol as the solvent, and RTV-II as the base paint can meet the requirements of self-detection of temperature by power equipment with its adhesion performance. The accelerated aging tests using high temperature, light and humidity were carried out in the laboratory, and we concluded that the deterioration degree of the color-changing coating was positively correlated with the temperature. Light can accelerate the aging rate of reversible color-changing coatings, and the degradation process of the coating was significantly accelerated under UV light. The effect of humidity on the coating was not significant. The degradation of the coating after aging for 288 h under indoor conditions was small, while it was accelerated under outdoor natural conditions. This research can provide a reference for the on-site application of reversible color-changing coatings for self-detection of temperature by power equipment.

电力设备温度自检测可逆变色涂料的附着特性及老化性能

为了及时发现异常发热情况，提出了一种电力设备自检测温度的可逆变色涂层测温方法，并对其附着特性和老化性能进行了分析。结果表明，以结晶紫内酯为着色剂、双酚A为显色剂、十八醇为溶剂、RTV-II为底漆制备的可逆变色涂料能够满足自检测温度的要求。电力设备以其粘附性能。在实验室进行高温、光、湿加速老化试验，得出变色涂层的劣化程度与温度呈正相关。光可以加速可逆变色涂层的老化速度，并且在紫外光照射下涂层的降解过程明显加速。湿度对涂层的影响不显着。室内条件下老化288 h后涂层的降解较小，而室外自然条件下则加速。该研究可为电力设备温度自检测可逆变色涂料的现场应用提供参考。
