Problems solved by technology
Hot-dip galvanizing is pure zinc plating, and its corrosion resistance is weak. Generally speaking, the neutral salt spray test does not exceed 500 hours; hot-dip galvanizing is an improved process of hot-dip galvanizing, and its corrosion resistance is significantly enhanced, but Due to the dense surface, a fluffy zinc oxide layer cannot be formed in the coating, and the effect of cathodic protection becomes poor
[0003] At present, the coatings formed by zinc-aluminum plating solutions on the market have poor heat resistance, corrosion resistance, adhesion and film-forming properties, and are easy to fall off.
Moreover, waste water, waste gas and waste residues that pollute the environment are produced during the production process.

Abstract
The invention discloses an environment-friendly zinc-aluminum plating solution which is prepared from the following raw materials in parts by weight: 5 to 32 parts of zinc powder, 5 to 32 parts of aluminum powder, 7 to 53 parts of binding agent, 1 to 10 parts of accelerant, 1 to 28 parts of additive and 10 to 64 parts of solvent A. The environment-friendly zinc-aluminum plating solution is prepared from the zinc powder, the aluminum powder, the accelerant, the additive and the inert organic solvent, wherein the zinc powder and the aluminum powder are in scale shapes. The zinc-aluminum platingsolution disclosed by the invention has the advantages of no chromium, low curing temperature, short curing time and good film formation property; a cured coating layer has excellent hardness, toughness, thermal resistance, corrosion resistance and wear resistance and is especially suitable for surface protection of profiled components of lamp poles, steel tubes, accessories and the like.
Description
technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to an environment-friendly zinc-aluminum plating solution and a preparation method thereof. Background technique [0002] Iron and steel products are widely used in national production and life. When used in the atmosphere, soil, seawater and other environmental conditions, they will be oxidized and corroded to varying degrees, resulting in serious economic losses and waste of natural resources and energy. Hot-dip galvanizing is a commonly used method to prevent corrosion, usually there are hot-dip galvanizing, hot-dip galvanizing and other methods. Hot-dip galvanizing is pure zinc plating, and its corrosion resistance is weak. Generally speaking, the neutral salt spray test does not exceed 500 hours; hot-dip galvanizing is an improved process of hot-dip galvanizing, and its corrosion resistance is significantly enhanced, but Due to the dense surface, a ...
