Abstract

The invention relates to an anticorrosive high-rigidity ceramic coating. The coating comprises the following components in percentage by weight: 20 to 40 percent of epoxy resin, 30 to 50 percent of submicron ceramic powder, 5 to 10 percent of titanium pigment, 15 to 20 percent of epoxy resin curing agent and 1 to 5 percent of high polymer dispersant. The coating of the invention can provide effective protection for the surfaces of metals such as an aluminum alloy and the like. The coating has excellent anticorrosive performance and mechanical performance, wherein the mechanical performance is that the rigidity is 4H and the adhesive force is 1 level. The rigidity of an ordinary epoxy coating is 2H. The coating is more applicable for the fields of aerospace, ocean shipping, chemical engineering and the like.

Description

technical field [0001] The invention relates to a ceramic coating, in particular to an anti-corrosion high-hardness ceramic coating. Background technique [0002] Among the metal materials, the aluminum alloy base material is widely used in the fields of aerospace equipment, airports, subways and architectural decoration due to its unique mechanical properties, anti-corrosion properties, lightness and beauty. Usually, in order to improve the anti-corrosion, weather resistance and other properties of the material and prolong its service life, the aluminum alloy material must be protected before it is used. There are many ways to treat the surface of aluminum alloy. From the perspective of development trend, it has gone through the following development stages: silver white anodizing → electrolytic coloring after anodizing → thick film anodizing → electrophoretic coating after anodizing (electrolytic coloring) Installation→electrostatic spraying after chemical conversion (pow...
