摘　　要：以RTV型防污闪涂料为基体,FeMnCuO4粉料作为吸热材料,制备了吸热型RTV防覆冰涂料,研究了FeMnCuO4添加量对RTV涂料整体憎水性能、电气性能及吸热效率的影响。结果表明,FeMnCuO4质量分数在8%左右,RTV涂料基体质量分数在92%时,该防覆冰涂料具有较好的综合性能;并且涂料憎水性、憎水迁移性、憎水丧失及恢复特性、自洁性、体积电阻率、相对介电常数性能均超过相关标准要求;光能吸收率达到77.7%,可以满足现场输电线路绝缘子防覆冰的需求。Endothermic RTV( ERTV) ice-covering-proof coating is prepared based on anti-pollution coating of RTV,using FeMnCuO4 as heat-sink materials. The author has analyzed the effect of FeMnCuO4 on the total hydrophobicity,electrical property and heat absorption efficiency of ERTV. Results show that when mass fraction of FeMnCuO4 is about 8%,and RTV is about 92%,ERTV has a better comprehensive performance,and has excellent hydrophobicity,hydrophobic mobility,hydrophobic loss and recovery characteristic,self-cleaning,volume resistivity and relative dielectric constant performance,which can satisfy the requirements of relevant standards,and light energy absorption rate of ERTV is over 77. 7%,which can meet the ice-covering prevention requirements of the insulators in transmission lines.
