Problems solved by technology

However, this coating contains hexavalent chromium, which has certain pollution.
And due to the needs of passivation and bonding, 5%-10% chromic anhydride is generally added, and Cr6+ is highly toxic and carcinogenic, so it has serious harm to the environment and human body
In addition, the curing temperature of this coating is as high as 300°C, and the curing time is about 30 minutes, which consumes a lot of energy; it has low hardness and poor wear resistance.

Abstract

The invention relates to a coating for marine climate-resistant engineering part preservative treatment, which comprises 30.0 to 50.0g of aluminum-zinc-silicone alloy powder, 10.0 to 25.0mL of organic solvent, 1.0 to 4.0g of nano-oxide particle reinforcing agent, 15.0 to 30.0mL of deionized water, 2.0 to 5.0g of adhesive, 1.0 to 3.0g of corrosion inhibitor, 0.1 to 2.0mL of a dispersing agent and 0.1 to 2.0g of thickening agent, wherein the aluminum-zinc-silicone alloy powder consists of aluminum, zinc, silicone, magnesium and nickel.

Description

technical field [0001] The invention relates to a water-soluble aluminum-zinc-silicon paint for anticorrosion treatment of marine climate-resistant engineering parts and a preparation method thereof. Background technique [0002] Offshore and marine engineering equipment is located in an environment with rainy, high temperature, salty fog and strong wind currents. According to the ISO9225 environmental evaluation standard, its service conditions are generally >C5 level, which belongs to the extremely harsh environment. The exposed parts will be subject to the combined effects of strong atmospheric corrosion, electrochemical corrosion and airflow erosion, and the service life of various steel structures is much lower than that of the general inland outdoor environment. For example, the wind power generation equipment in service under marine climate conditions is directly exposed to the extreme corrosive atmosphere due to the external components of the unit such as the nace...
