Abstract

The invention provides a plating assistant agent for zinc-aluminum-nickel-rare earth-alloy hot-dip plating and a technological method. The plating assistant agent comprises the following components of an A solution containing zinc chloride, ammonium chloride, stannous chloride and urotropin and a B solution containing ethyl alcohol, a nonionic surfactant and a cationic surfactant, wherein the plating assistant agent is obtained by mixing the A solution and the B solution. By using the plating assistant agent, skip plating can be effectively avoided; and the surface quality of a plating layer is obviously improved; the yield of a plated article is improved; and the corrosion-resistance of the plating layer can be obviously improved. The plating assistant agent does not contain fluorinion which is harmful to the environment, and requirement of environment protection is met.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion technology for iron and steel materials, and relates to the surface coating technology of iron and steel materials, in particular to a special plating flux formulation and a hot-dip plating process suitable for the hot-dip galvanized aluminum-nickel rare earth alloy coating of steel materials. Background technique [0002] Hot-dip galvanizing can significantly improve the ability of steel to resist atmospheric corrosion. It is one of the main means for steel to prevent atmospheric corrosion and has been widely used in engineering. The protective function of the galvanized layer includes: on the one hand, it provides a physical protective barrier for steel to prevent external corrosive media from corroding it; on the other hand, it can be used as a sacrificial anode to provide cathodic protection for steel materials. With the development of science and technology and modern industry, higher ...
