Problems solved by technology

[0003] The deplating technology in the field of automotive mold PVD originated from Japan, and the efficiency of deplating using Japanese deplating solutions is low. At the same time, such deplating solutions themselves are hazardous chemicals, and there are certain difficulties in importing and purchasing. At present, there is no suitable solution in China. The deplating solution in the PVD field of automobile molds, so domestic factories use grinding molds as the main deplating method, but due to the high hardness of PVD itself, physical damage may be caused during the grinding process, resulting in mold deformation that cannot be reproduced. use

Abstract

The invention relates to the field of cleaning agents, in particular to a car mold PVD stripping solution and a preparing method thereof. The stripping solution is composed of, by mass percent, 10 to30% of sodium permanganate, 10 to 30% of potassium hydroxide and 40 to 80% of deionized water. The strong oxidizing property of the sodium permanganate under the strong environment can be mainly usedfor carrying out stripping treatment on car mold PVD. In the prior art, the grinding manner is commonly used for stripping inland or a stripping solution imported from the Japan is used for stripping;compared with stripping in the grinding manner, the advantage that a mold cannot deform or is damaged is achieved, and compared with the imported stripping solution, the advantage of being high in stripping efficiency is achieved.

Description

technical field [0001] The invention relates to the field of stripping solutions, in particular to a stripping solution for automotive mold PVD and a preparation method thereof. Background technique [0002] Deplating solution, as the name implies, refers to the ability to effectively remove a layer of special metal or metal substance plating on the surface of the workpiece by soaking, heating, ultrasonic, electrolysis, etc., without dissolving or harming the substrate of the workpiece. Corrosive, non-discoloring chemical liquid. [0003] The deplating technology in the field of automotive mold PVD originated from Japan, and the efficiency of deplating using Japanese deplating solutions is low. At the same time, such deplating solutions themselves are hazardous chemicals, and there are certain difficulties in importing and purchasing. At present, there is no suitable solution in China. The deplating solution in the PVD field of automobile molds, so domestic factories use gr...
