摘要
以碳晶为填料制备环氧树脂基电热涂料,进而制得碳晶发热聚氨酯薄膜。对碳晶进行了X射线衍射分析、扫描电镜等测试,分析了碳晶电热涂料的体积电阻率、电热膜的电热性能及碳晶电热膜传感阵列网格尺寸与最高发热温度的关系。结果表明:6k碳纤维球磨24 h得到的碳晶最优;在碳晶含量为60%时,制备的聚氨酯薄膜电热转换效率最高,可达90%。
Epoxy resin-based electrothermal coatings were prepared with carbon crystals as fillers, and then carbon crystalline thermogenic polyurethane films were prepared. Carbon crystals were tested by X-ray diffraction and scanning electron microscopy. The volume resistivity of carbon crystalline electrothermal coatings, the electrothermal properties of electrothermal films and the relationship between the grid size of carbon crystalline electrothermal film sensor array and the maximum heating temperature were analyzed. The results show that the carbon crystal obtained by ball milling of 6 k carbon fiber for 24 h is the best;when the amount of carbon crystal is 60%, the electrothermal conversion efficiency of the prepared polyurethane film is the highest, up to 90%.
