Description

technical field [0001] The invention relates to the technical field of paint and coating thereof, in particular to an anti-corrosion coating with good lubricating performance and a coating process thereof. Background technique [0002] Coating is a solid continuous film obtained by one application of paint. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation and decoration. The paint can be gaseous, liquid, or solid, and the type and state of the paint are usually determined according to the substrate to be sprayed. [0003] Water instead of organic solvent or dispersion medium is the biggest feature of water-based coatings. Because of this, the use of water-based coatings can save a lot of petroleum resources and greatly reduce the pollution of the atmosphere caused by the volatilization of organic solvents in the coatings. The water-based polyurethane coating is a kind of water-based coating. On the b...
