Description
Technical field
The present invention relates to technical field of coatings, and in particular to a kind of anticorrosion abrasion-resistant coating material and preparation method thereof.
Background technique
In recent years, the metal material surfaces such as steel, aluminium, magnesium by coating process obtain corrosion-resistant, anti abrasive coating from
And corrosion-resistant, abrasion resistance properties the technologies for improving metal are used widely.Coating can be described as multi-component chemically composited
Body, its anticorrosion antiwear performance are the results of each component interaction.Coating mainly includes that film forming matter, pigment and solid are filled out
Material, solvent and decentralized medium and auxiliary agent.Anticorrosive paint can be divided by main film forming matter: anti-corrosive paint of epoxy resin, vinyl
Anticorrosive paint, aqueous epoxy resin emulsion anticorrosive paint, phenolic resin anticorrosive paint etc..
The advantages that organic coating anti-corrosion is because of at low cost, simple process and good effect, is widely used in metallic surface
Anti-corrosion, antisepsis mechanism mainly include two aspects, are physical isolation and chemoproection respectively.Physical isolation, briefly
Exactly metal and etchant solution are kept apart, if coat inside does not have gap, which can play good anti-corrosion effect
Fruit, but due to the solidification of organic resin, inside can generate defect as etchant solution channel.The chemoproection of coating acts on
The defect of physical isolation can be made up, coat inside can when etchant solution immersion coating by a bit active metal of addition
To play sacrificial action, parent metal is protected, referred to as coating has chemoproection effect.
The wearability and anti-corrosive properties of metal coating are insufficient in the prior art, and the service life is shorter, affects the long-time service of metal
Performance.
Summary of the invention
Aiming at the above shortcomings existing in the prior art, technical problem to be solved by the invention is to provide a kind of anti-corrosion is resistance to
Coating material and preparation method thereof is ground, obtained anticorrosion abrasion-resistant coating material has excellent corrosion resistance and wear-resisting property,
Hardness with higher simultaneously.
