热敏变色涂层的制备与温度变化模型的建立
Preparation of thermo-chromic coating and establishment of variable temperature model
电力设备通常会发生故障并伴随发热现象。因此通过发热现象可以估测设备发生故障的地点。热敏变色涂层在温度变化时颜色会发生改变，能够满足监测发热部位的需求。在本次研究中，课题组制备了几种变色温度范围不同的热敏涂层。研究了这些涂层的热敏性能，同时测量了实时温度下热敏涂层的颜色信息。建立了温度与颜色信息之间的数学模型。拟合结果显示各不同热敏变色涂层的温度变化模型相关性系数均在0.9以上。同时模拟应用试验的结果表明，在利用温度变化模型进行温度测量时，其误差在±1℃，反应了模型的可靠性。此外，还提出了热致变色涂层辅助非接触式温度测量方法。
6 reversible thermo-chromic coatings were prepared between thermo-chromic microcapsule and resin such as acrylic resin, silicone resin, respectively. The thermochromic performance and color coordinates (RGB) of the obtained thermochromic coating were evaluated. And models for displaying the relationship between temperatures and coating color coordinates were established using own experiment. Results showed that the correlation coefficient of each temperature model was above 0.9. The temperature measurement errors were about ±1 C after simulated trials of the model, which proved that the feasibility of measure temperature by using the variable temperature model. Also, a contactless method for obtaining specific temperature by thermochromic coating is proposed.
