preparation example Construction
[0032] The preparation method of modified borax, by weight, comprises:
[0033] (1) Mix and stir the silane coupling agent of 0.2-0.3 part and 50-70 parts of borax to obtain the borax mixture;
[0034] (2) take by weighing the vinyl alcohol monomer of 1 part-5 part, the sodium dodecylbenzene sulfonate of 0.1 part-0.5 part and the persulfate of 0.2 part-0.3 part are mixed with aqueous solution, then with step (1) The borax mixture in the mixture is mixed and hydrothermally reacted for 0.5-2 hours, and the modified borax is obtained after filtering and washing. The particle size of the modified borax is less than 100nm.
[0035] 4) Cleaning and drying the metal to be treated after the blasting treatment, and coating the surface of the metal to be treated.
[0036] The coating treatment of the metal surface to be treated includes the application of a protective lacquer layer.
Embodiment 1
[0039] A metal surface treatment process, comprising:
[0040] 1) Carry out the pre-treatment process to the metal to be treated to remove the grease on the surface of the metal to be treated;
[0041] 2) Put the metal to be treated in a heating furnace, heat it to 40°C, and then place it in a mist atmosphere of 5% sodium hydroxide under a pressure of 3MPa for 20 seconds, then neutralize it with acid, wash and dry it. Dry;
[0042] 3) Put the dried metal to be treated in the sand blasting machine, use borax to treat the metal to be treated by sand blasting for 15 minutes, and then bury the metal to be treated after sand blasting in modified borax at 180°C under a pressure of 5 MPa Infiltration for 4 hours;
[0043] 4) The metal to be treated after the blasting treatment is cleaned, dried, and then subjected to surface coating treatment of the metal to be treated; the surface coating treatment of the metal to be treated includes plating a protective paint layer.
