Description

technical field [0001] The invention relates to the technical field of paint and coating thereof, in particular to a 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] Epoxy coatings are generally divided into two types: oil-based epoxy coatings and water-based epoxy coatings. According to the performance, there are generally wear-resistant epoxy coatings and epoxy anti-corrosion coatings. Strict divisions should also include anti-static epoxy coatings and architectural environmental protection coatings. Oxygen decorative paint. [0004] However, the coatings cur...
