Abstract

The invention discloses a graphene wear-resistant coating, and belongs to the technical field of new material coatings. The graphene wear-resistant coating is prepared from the following components in percentage by mass: 80 to 70 percent of first component and 20 to 30 percent of second component, wherein the first component is prepared from the following raw materials in percentage by mass: 20 to 35 percent of modified epoxy resin, 0.5 to 5 percent of aid, 0.5 to 4 percent of graphene, 2 to 2.5 percent of adhesive agent, 5 to 8 percent of pigment, 15 to 17 percent of filler, 7 to 9 percent of covering polymer and 20 to 25 percent of solvent; the second component is prepared from 20 to 30 percent of curing agent. By adopting the graphene wear-resistant coating provided by the invention, the friction coefficient and wear rate of the coating are lowered effectively; on the other hand, the graphene has high heat resistance and heat conductivity, so that heat generated in a friction process is dissipated well, and chemical degradation caused by local overheat on the surface of the coating is prevented.

Description

technical field [0001] The invention belongs to the technical field of new material coatings, and in particular relates to a graphene wear-resistant coating and a preparation method of the coating. Background technique [0002] Organic coatings are coatings composed of polymer compounds as the main film-forming substances. Applying it on the surface of the object can form a layer of coating film with strong adhesion. Paint, formerly known as paint, was named after mostly vegetable oil was used as raw material in the early days. With the development of synthetic materials industry, most of the vegetable oil has been replaced by synthetic resin, so it was renamed paint. [0003] At present, there are many kinds of coatings on the market, but many coatings generally have a high friction coefficient and wear rate on the coating surface after spraying. In addition, the coating surface is prone to chemical degradation due to local overheating. Contents of the invention [0004...
