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.

Description

technical field [0001] The invention discloses an anti-corrosion powder coating, in particular to a temperature-resistant anti-corrosion and wear-resistant powder coating as well as its preparation method and application. Background technique [0002] In various fields of production and life, metal materials, such as steel and aluminum, are widely used. In order to increase their service life, the anti-corrosion problem of these metal surfaces has always been closely concerned by people. In order to solve the anti-corrosion problem, people continue to develop new anti-corrosion materials. The most commonly used anti-corrosion method is to spray paint. However, paint is usually used in wood processing, and it is not suitable for some heavy-duty anti-corrosion industries. [0003] ZL97111379.3 discloses elastic anti-corrosion and wear-resistant powder coating and its coating method, and ZL00126503.2 discloses high-strength anti-corrosion and wear-resistant powder coating and ...
