Abstract

The invention provides anti-impacting and cold-resisting coating based on graphene powder and a preparation method thereof. The anti-impacting and cold-resisting coating based on the graphene powder is prepared from the following components in parts by mass: 50 to 70 parts of epoxy resin, 30 to 40 parts of phenolic aldehyde type vinyl ester resin, 5 to 8 parts of polyvinyl alcohol, 4 to 8 parts of polytetrafluoroethylene emulsion, 5 to 10 parts of a dispersant, 2 to 6 parts of a de-foaming agent, 1 to 5 parts of a preservative, 20 to 50 parts of fillers, 0.3 to 1.2 parts of the graphene powder and 50 to 60 parts of de-ionized water. According to the coating provided by the invention, the epoxy resin, the phenolic aldehyde type vinyl ester resin, the polyvinyl alcohol and the polytetrafluoroethylene emulsion are added so that the coating has good anti-impacting, cold-resisting and anti-corrosion properties; furthermore, the graphene powder is additionally added, so that the comprehensive properties, especially the anti-impacting and cold-resisting properties, of the coating are improved.

Description

technical field [0001] The invention relates to the field of impact-resistant and cold-resistant coatings, in particular to an impact-resistant and cold-resistant coating based on graphene powder and a preparation method thereof. Background technique [0002] Coating refers to a type of liquid or solid material that can form a thin film on the surface of an object under certain conditions to protect, decorate or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). The coating industry belongs to modern industry, but the paint itself has a long history. China is the earliest country in the world to use natural resin as the coating lacquer of film-forming substance. The mineral colors used by early painters were water suspensions or formulated with water or albumin. This was the earliest water-based paint. [0003] Chinese Patent Publication No. 104327670A discloses an impact-resistant, cold-resistant and anti-corrosion coating. It...
