Abstract

The invention discloses a graphene nonstick paint, and aims to solve the problem of high energy consumption caused by weak thermal conductivity of an existing nonstick paint. The invention employs graphene to modify a nonstick paint, and the addition of the graphene accounts for 0.1-5wt% of the nonstick paint. The graphene nonstick paint provided by the invention can substantially improve heat conduction effect of a nonstick coating, save energy and reduce consumption, without influencing other indexes of the coating, such as viscosity, adhesive force, heat resistance, friction resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of non-stick coating production, in particular to a graphene non-stick coating. Background technique [0002] Non-stick coating is a special coating whose coating surface is not easily adhered by other sticky substances or easily removed after adhesion. Therefore, the coating formed by this kind of coating has the characteristics of extremely low surface energy, small friction coefficient, easy sliding and other anti-stick properties, and is widely used in household appliances, cooking utensils, automobiles, machinery, chemical industries and other industries. The currently successfully developed non-stick coatings are mainly polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF) and various fluorine-containing resins with functional groups. According to the medium and state of the coating, non-stick coatings can be divided into water-based, solvent-based and powder types. Water-based non-stick coa...
