Abstract

The present invention relates to surface treatment of steel plate, and is especially zinc electroplating process to form homogeneous fine zinc layer onto the surface of cold rolled steel plate and environment friendly zirconium-containing no-chromium fingerprint resisting paint for producing zinc electroplating fingerprint resisting steel plate. Cold rolled steel plate is first electroplated with zinc and then coated with fingerprint resisting paint. The production process of fingerprint resisting steel plate features the production process including the first production of zinc electroplated steel plate via vertical anode electroplating process, coating with water-base fingerprint resisting paint with zirconium to replace chromium, and curing through roasting at temperature lower than 125 deg.c to form composite resin film. The electroplated zinc layer has stable and reliable quality and the organic composite resin film has no environmental pollution.

Description

Technical field:

[0001] The invention relates to a surface treatment method of an environment-friendly chromium-free zirconium-containing electro-galvanized anti-fingerprint steel plate. It specifically relates to an electro-galvanizing process method for forming a uniform and fine zinc layer on the surface of a cold-rolled steel plate, and an environment-friendly chrome-free zirconium-containing anti-fingerprint coating for manufacturing an electro-galvanized anti-fingerprint steel plate. Background technique:

[0002] The anti-fingerprint steel plate is a high value-added product that uses a cold-rolled plate as the substrate after electrogalvanizing, and then coats a 1-3 μm thick organic composite resin film on the surface of the plate. Fingerprint-resistant steel products have a beautiful appearance,

[0003] High corrosion resistance, excellent fingerprint resistance, good electrical conductivity, blackening resistance, scratch resistance, high chemical stability; the ...
