Abstract

The invention provides a corrosion resistance coating for steel and a preparation method thereof. The coating has the advantages of excellent performance and good wear resistance. The preparation method has the advantages of simple process and low production cost and is suitable for industrial production. The corrosion resistance coating for steel comprises the following compositions in percentage by weight: 40-45 percent of alloy powder, 3.0-6.0 percent of boron nitride powder, 3-6 percent of silicon carbide powder, 7.0-8.0 percent of butanol powder and the balance of epoxy resin liquid, wherein the particle size of the alloy powder, the particle size of the boron nitride powder and the particle size of the silicon carbide powder are all 270-800 meshes. The alloy powder comprises the following compositions in percentage by weight: 35-40 percent of Zn, 0.01-0.1 percent of Mn, 0.2-0.4 percent of Cd, 0.2-0.4 percent of Sr, 0.02-0.05 percent of Si, 0.03-0.09 percent of Prm 0.05-0.2 percent of Gd and the balance of Al.

Description

1. Technical field [0001] The invention belongs to the field of metal materials, and relates to a corrosion-resistant coating for steel and a preparation method thereof. 2. Technical background [0002] At present, in the field of coating materials, the corrosion protection of steel has been paid attention to. [0003] Application No. CN200710113712.4 discloses a corrosion-resistant and wear-resistant powder coating, which is composed of a base material, a filler and a coupling agent. The base material is selected from thermoplastic polyamide resin, and the filler is carbon fiber and molybdenum disulfide. In order to disperse evenly and improve the compatibility between the filler and the base material, this invention also adds a small amount of γ-glycidyl ether propyl trimethoxysilane as a coupling agent. The preparation method of anti-corrosion and wear-resistant powder coating, weighing 100 parts of thermoplastic polyamide resin, 0.2-1 part of carbon fiber, 1-3 parts of...
