Abstract

The invention relates to a transparent powder coating, specifically to a graphene transparent powder coating for tribo gun to spray an MDF plate. The graphene transparent powder coating is prepared from the following raw materials in percentages: 30 to 60% of polyester resin, 24 to 48% of epoxy resin, 0.8 to 1.2% of a leveling agent, 0.5 to 1.0% of a gloss enhancer, 0.5 to 1.0% of wax powder, 0.3 to 0.8% of benzoin, 1.0 to 2.0% of a triboelectric charging additive and 0.02 to 0.1% of graphene. According to the invention, powder coating is realized by using a tribo gun through addition of the triboelectric charging additive; by adopting a method of spraying a powder coating with the tribo gun, no Faraday effect is generated; meanwhile, no free ions are generated; charged powder ions may not mutually exclude; a formed coatingn film has good leveling properties; and through addition of graphene, the transparent powder coating can be improved in glossiness, adhesive force, water resistance, conductivity, flexibility, etc.

Description

technical field [0001] The invention relates to a graphene transparent powder coating, in particular to a graphene transparent powder coating which is sprayed on an MDF board by a friction gun. Background technique [0002] The friction gun is a positively charged powder coating produced by the collision and friction between the powder coating and the polymer material (PTEF) in the gun wall. After the powder coating leaves the friction gun, its driving force is only provided by the airflow, and no Faraday will be generated. Effect, so it is more possible to spray a uniform coating on complex workpieces, and the coating surface is smoother. Powder coatings sprayed with triboguns must have special triboelectric agents added to the powder coatings. [0003] Graphene is a two-dimensional honeycomb hexagonal structure formed by densely packed carbon atoms. This structure is very stable. So far, researchers have not found the absence of carbon atoms in graphene. Each carbon atom...
