[0038] The present invention provides a method for preparing the corrosive solution described in the above technical solution, comprising the following steps:
[0039] Mix picric acid with part of the mass of water to obtain a solid-liquid mixture;
[0040] Heating the solid-liquid mixture to a boiling state and maintaining the boiling state for 3 to 5 minutes to obtain a hot saturated picric acid solution;
[0041] cooling the hot saturated picric acid solution to 60-90°C, and filtering to obtain a picric acid supersaturated solution;
[0042]The picric acid supersaturated solution is mixed with a surfactant solution, and then mixed with a catalyst to obtain a corrosion solution; the surfactant solution includes a surfactant, ethanol and remaining water.
[0043] The invention mixes picric acid with part of the mass of water to obtain a solid-liquid mixture. In the present invention, in terms of parts by mass, the part of water by mass is preferably 85-95 parts, more prefer...
Embodiment 1
[0074] Measure 80ml of tap water with a graduated cylinder and pour it into a beaker for later use; weigh 0.90g of sodium dodecylbenzenesulfonate with an electronic scale, mix it with 10mL of water and 10mL of absolute ethanol, and obtain a sodium dodecylbenzenesulfonate solution for use use. At 1000rpm, add 4.00g of solid picric acid into a beaker filled with water while stirring to obtain a solid-liquid mixture; raise the temperature of the solid-liquid mixture to 100°C, keep the temperature constant for 3min, until it reaches a supersaturated state, and then cool down to 70°C Filtrate, add sodium dodecylbenzenesulfonate solution to the filtrate, and then dropwise add 4 drops of hydrochloric acid solution with a mass fraction of 37%, and keep the temperature at a constant temperature for 5 minutes under stirring to obtain a corrosion solution.
