Embodiment 1

[0023] Use a bio-environmental protection degreasing agent to clean and degrade the oil stain on the surface of the metal plate. After the oil stain is removed, use tap water to rinse the degreased metal plate for 2-5 minutes to wash off the bio-environmental protection degreasing agent on the surface, and the metal plate Completely immerse in any one of hydrochloric acid, sulfuric acid and nitric acid to pickle and activate the metal plate to dissolve the oxide film on the surface of the metal plate to expose the active metal interface, and use pure water to rinse the activated metal plate 2 -5min, wash off the acidic solution on the surface, coat the surface of the metal sheet with a zinc film with an average thickness of 70μm after the activation is completed, rinse the metal sheet with tap water for 2-5min after hot-dip galvanizing Silica with a particle size of 4-6nm, 10% titanium salt, 10% water-based acrylic resin, 2% amino resin crosslinking agent, 45% passivation solut...

Abstract

The invention relates to the technical field of accessory devices, in particular to a metal plate surface fingerprint-resistant treatment method. The metal plate surface fingerprint-resistant treatment method can improve the corrosion resistance of a fingerprint-resistant plate, enables the fingerprint resistance, the ground connection performance and the corrosion resistance to be good and meet the requirement for a core assembly so as to meet the user requirement, passivation and the fingerprint-resistant treatment can be conveniently carried out at the same time, and consumed time is shortened; the method comprises the following steps that (1) oil stains are removed on the metal surface; (2) activating treatment is carried out; (3) hot galvanizing is carried out; (4) treating fluid is prepared; (5) treatment is carried out; (6) baking and curing are carried out; (7) cooling is carried out; (8) washing is carried out; and (9) drying is carried out.

Description

technical field [0001] The invention relates to the technical field of accessory devices, in particular to a method for anti-fingerprint treatment on the surface of a metal plate. Background technique [0002] As we all know, anti-fingerprint board is a kind of composite coating board obtained after anti-fingerprint treatment on the surface of galvanized metal sheet. The anti-fingerprint board was originally to meet the requirements of users in the field of adding points. In the production process of home appliances, due to process needs, Many parts have been touched by workers many times, and the sweat stains on the workers' hands will form pollution on the surface of the parts, which will affect the appearance. Therefore, the anti-fingerprint board has been researched and developed. The main application of thin organic-coated steel sheets with fingerprint resistance is the inner and outer panels of various home appliances. The largest domestic demand for fingerprint-resist...
