Abstract

The invention discloses heavy anti-corrosion powder, which is prepared from the following raw materials in percentage by weight: 50 to 55 percent of epoxy resin, 6 to 9 percent of curing agent, 0.1 to 0.4 percent of dimethylimidazole, 4 to 5.5 percent of auxiliary agent, 9 to 11 percent of preservative, 22 to 25 percent of filler and 0.6 to 0.9 percent of carbon black.The anti-corrosion agent is one of sodium benzoate, sodium diacetate and propyl benzoate, and the filler is one of pore plate corrugated filler and a metal Pall ring. The invention relates to the technical field of heavy anti-corrosion powder. According to the heavy anti-corrosion powder, the adhesive force of the heavy anti-corrosion powder can be greatly improved through the composition of the epoxy resin, the curing agent, the dimethylimidazole, the auxiliaries, the preservative, the filler and the carbon black, so that the heavy anti-corrosion powder has very good adhesive force with a base material, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of heavy-duty anti-corrosion coatings, in particular to a heavy-duty anti-corrosion powder. Background technique [0002] Heavy-duty anti-corrosion coating: refers to a type of anti-corrosion coating that can be applied in a relatively harsh corrosive environment and has a longer protection period than conventional anti-corrosion coatings. It can be used under harsh conditions and has a long-term effect. Anti-corrosion life, heavy-duty anti-corrosion coatings can generally be used for 10 or 15 years in chemical atmospheres and marine environments, and can be used for more than 5 years even in acid, alkali, salt and solvent media and under certain temperature conditions. [0003] Heavy-duty anti-corrosion coating is a kind of coating that can be used effectively for a long time under severe conditions. Some anti-corrosion coatings have poor adhesion and cannot meet people's needs, which has become a problem ...
