Abstract

The invention discloses a micro arc oxidation composite stain resistant coating and a production method thereof. The production method specifically comprises the following steps that 1, a well prepared metal board substrate is mechanically polished, and the corners and the hiding parts are polished through manpower assistance; 2, the metal board substrate polished in the step 1 is placed into a ultrasonic cleaner to be rapidly washed by adding clean water and a sodium hydroxide solution and utilizing ultrasonic waves; 3, the washed metal board substrate in the step 2 is rapidly blown dry in warm air, the greasy stains and rusty spots on the surface of the substrate are removed; and 4, a micro arc oxidation electrolytic solution of potassium hydroxide, sodium sulfate and potassium fluorideis prepared and aged for stand-by application. The production method utilizes a coating machine to spray a layer of silicone fluoride modified coating on the surface of a ceramic layer, the silicone fluoride modified coating has the good anti-adhesion performance, anti-graffiti performance, outdoor durability, cold and hot resistance, stain resistance, anti-scrubbing performance and solvent resistance, and is waterproof and anti-creeping.

Description

technical field [0001] The invention belongs to the technical field of composite coating production, and in particular relates to a micro-arc oxidation composite anti-corrosion coating and a production method thereof. Background technique [0002] The surface of the metal plate is easy to stick to oil and wear, and most of the phenomena occur on the surface of the mechanical processing table in the factory. Therefore, the use of surface treatment technology to improve the wear resistance of the surface of the material will improve the safety and reliability of its use, facilitate cleaning and prolong the service life. , has very important significance and development prospects. The disadvantages of low hardness, high friction coefficient, poor wear resistance, high temperature oxidation and poor crack resistance of metal sheets seriously affect the performance of metal sheets and limit their application in various fields. scope. Contents of the invention [0003] The obje...
