Description
Technical Field
The invention relates to the technical field of metal surface treatment materials, in particular to a quick-drying chromium-free fingerprint-resistant liquid for galvanized steel sheets.
Background
At present, hot dip galvanized steel sheets are widely used in electronic products in household appliances and IT industries, such as computer cabinets, and because the computer cabinets need to be manually participated in the process of processing and forming, fingerprint-resistant galvanized steel sheets are often used in production factories in order to avoid sweat stains on hands of workers to remain on the surfaces of cabinet steel sheets and influence the subsequent coating performance and the attractiveness.
In order to eliminate fingerprint marks, the surface of a galvanized steel sheet is generally treated to prevent fingerprints from being transferred or attached, namely, the components forming the fingerprints are not sticky on the surface and cannot be kept in a state, so that the problem of product value reduction caused by attaching the fingerprints and palm prints is solved, and the hot-dip aluminum zinc fingerprint-resistant coating is mainly divided into chromate passivation and chromium-free passivation at present. Although the chromate passivation treatment can obviously improve the corrosion resistance of the aluminum and the aluminum alloy surface, and meanwhile, the passivation film has good adhesive force to the coating and low cost, along with the improvement of environmental protection requirements, the chromate passivation is gradually eliminated, the chromium-free passivation is a necessary trend of development, and the chromium-free passivation can reduce certain harm to the environment.
The existing chromium-free fingerprint-resistant liquid is generally coated on a galvanized steel sheet in a roller coating mode, and needs to be dried after coating, but the existing chromium fingerprint-resistant liquid needs to be dried for a longer time, and then needs to be subjected to the next process flow and transportation and storage, so that the production efficiency is greatly reduced, and the environment-friendly chromium-free fingerprint-resistant liquid with excellent quick-drying property, corrosion resistance and fingerprint resistance is developed.
