Abstract

The invention relates to a low-temperature anti-fingerprint surface treatment agent for galvanized steel sheets and an environment-friendly surface-treated galvanized steel sheet obtained by using the surface treatment agent for surface treatment. The surface of the galvanized steel sheet of the present invention does not contain chromium and does not require high-temperature drying, and can form a surface treatment film under low-temperature drying conditions. The manufacturing process is environmentally friendly and low in energy consumption. The composition of organosilicon compound, titanium compound, vanadium compound and oxidized polyethylene particles (i.e. surface treatment agent) is coated on the surface of galvanized steel sheet, and then dried at a low temperature of 50-75°C, and the surface-treated galvanized steel sheet obtained is simultaneously It has excellent properties such as alkali resistance, solvent resistance, corrosion resistance, fingerprint resistance and coating adhesion.

Description

technical field [0001] The invention belongs to the field of surface treatment of metal materials, and relates to a low-temperature anti-fingerprint surface treatment agent for galvanized steel sheets and an environmentally friendly surface-treated galvanized steel sheet obtained by using the surface treatment agent for surface treatment. The surface of the galvanized steel sheet does not contain chrome and does not require high-temperature drying, the manufacturing process is environmentally friendly and low energy consumption, and the surface-treated galvanized steel sheet also has excellent properties such as alkali resistance, solvent resistance, corrosion resistance, fingerprint resistance and coating adhesion . Background technique [0002] Metal materials such as zinc-containing metal steel sheets and aluminum sheets are widely used in the automobile, building materials, and home appliance industries. However, zinc and aluminum using the above metal materials will be...
