Environment friendly depainting powder and preparation method thereof

The invention provides environment friendly depainting powder. The environment friendly depainting powder is prepared from raw materials in percentage by mass as follows: 48%-72% of sodium hydroxide,10%-20% of sodium carbonate, 3%-4% of lauryl sodium sulfate, 10%-20% of sodium silicate and 5%-8% of coconut oil diethanolamine. The environment friendly depainting powder is used for environment friendly depainting of paint layers applied to surfaces of stainless steel, titanium alloy, steel and chromium alloy during machining, is pollution-free to the environment, and has little harm to the bodyof an operator; the environment friendly depainting powder is suitable for surface depainting of the stainless steel, titanium alloy, steel and chromium alloy, can remove grease compounds on the surface of alloy workpieces simultaneously and cannot affect further machining performance such as welding, laser processing, sealing and the like of the workpieces. 本发明提供种环保型脱漆粉，所述环保型脱漆粉的各原料的质量百分比为：氢氧化钠48～72%，碳酸钠10～20%，十二烷基硫酸钠3～4
