[0031] The embodiment of the present invention provides a method for preparing a matte stainless steel surface, comprising the following steps:
[0032] Step 1: Cut the stainless steel plate test piece with a thickness of 0.5mm into a block of 10cm*10cm, and clean it;
[0033] Step 2: Put the stainless steel in a mechanical polishing machine for grinding and polishing for 3 minutes, wash and dry after polishing, and wait for treatment;
[0034] Step 3: the preparation of stainless steel sand surface etching solution: by weight, get 20 parts of concentration to be 38% hydrochloric acid, 20 parts of FeCl 3 ·6H 2 O and 3 parts of quartz sand with a particle size of 50 nanometers and 60 parts of deionized water are mixed as raw materials;
[0035] Step 4: Put the polished stainless steel sample in the sand surface etching solution prepared in Step 3, and perform ultrasonic etching at 25°C for 60 minutes. After the reaction is completed, take out the test piece, rinse it with dei...
