The invention relates to a heatproof anticorrosion wear resistant powdery paint, a preparation method and an application. The powdery paint comprises the following raw materials by weight: 80-100 parts of phenol novolac epoxy, 25-35 parts of bisphenol A-epoxy resin matrix, 4.0-5.5 parts of dicyandiamide, 80-120 parts of cast stone powder, 10-40 partsof polypropylene, 5-8 parts of graphite, 5-8 parts of component A, 2-5 parts of aluminum hydroxide, 1-3 parts of magnesium oxide, 5-7 parts of ethyl lactate, 1-3 parts of polyvinyl butyral, 5-8 parts of copper oxide, 1-5 parts of carbon nanotube, 0.1-2 parts of 2,4,5-trichlorobenzene sulfonate, 0.2-1 part of potassium perfluorobutanesulfonate and 0.1-0.4 parts of phenylsulfonyl benzene sulfonic acid potassium. According to the invention, phenol novolac epoxy is taken as a base, the bisphenol A-epoxy resin matrix is added, the carbon nanotube is added in the anticorrosion paint, the heatproof and anticorrosion performances of the paint can be enhanced, and the coating process is simple.
