The invention provides a disc-type insulator surface silicone rubber coating layer removing agent and a preparation method and application thereof, wherein the removing agent can rapidly and stronglyremove a coating layer at room temperature without damaging an insulator. The removing agent comprises the components in percentage by mass: 2%-4% of tetramethylammonium hydroxide, 10%-15% of ethanol,8%-15% of diethylamine, 35%-45% of tetrahydrofuran, 5%-12% of ethylene glycol phenyl ether, 5%-12% of N-octyl pyrrolidone and 3%-5% of a penetrating agent; or 2%-4% of potassium hydroxide, 10%-15% ofethanol, 8%-15% of diethylamine, 35%-45% of butanone, 5%-12% of dimethyl sulfoxide, 5%-12% of butyronitrile and 3%-5% of penetrant; or 2%-4% of sodium ethoxide, 10%-15% of ethyl alcohol, 8%-15% of diethylamine, 35%-45% of butanone, 5%-12% of ethylene glycol phenyl ether, 5%-12% of N-octyl pyrrolidone and 3%-5% of a penetrant. 本发明提供了盘式绝缘子表面硅橡胶涂层脱除剂及其制备方法与应用，脱除剂能够在室温下快速强力脱除涂层，同时不损伤绝缘子。脱除剂成分配比为：四甲基氢氧化铵2％～4％，乙醇10％～15％，二乙胺8％～15
