Abstract

The invention relates to a low-temperature anti-fingerprint surface treating agent for a galvanized steel sheet and an environment-friendly surface treated galvanized steel sheet of which the surface is treated by use of the surface treating agent. The surface of the galvanized steel sheet does not contain chromium and does not need to be dried at a high temperature, and a surface treatment film can be formed on the surface under a low-temperature drying condition; the manufacturing process is environment-friendly and low in energy consumption; a composition (namely the surface treating agent) containing specific water-based resin and phosphide, specific organic silicon compound, titanium compound, vanadium compound and oxidic polyethylene particles is applied to the surface of the galvanized steel sheet and then dried at a low temperature ranging from 50 to 75 DEG C, and consequently, the obtained surface treated galvanized steel sheet has excellent properties such as excellent alkali resistance, solvent resistance, corrosion resistance, fingerprint resistance, coating adherence and the like.

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...
