Antirust drawing oil for air-conditioner sheet metal part

Abstract

The invention discloses antirust drawing oil for an air-conditioner sheet metal part, and belongs to the technical field of air-conditioner sheet metal parts. The antirust drawing oil is composed of coating agents and antirust agents. The antirust agents are composed of benzotriazole and petroleum barium sulfonate, wherein the mass ratio of the benzotriazole to the petroleum barium sulfonate is 2 to 5. The coating agents are composed of paint materials and diluents, the mass ratio of the paint materials to the diluents is 100 to 2, and the diluents comprise, by mass, 100 parts of gasoline, 20 parts to 25 parts of X-4-amido paint diluents, 10 parts to 12 parts of zinc dialkyl dithiophosphate, 7 parts to 9 parts of diethylene glycol ethyl methyl ether, 4 parts to 7 parts of methylisobutylketone, 6 parts to 8 parts of isopropanol, 5 parts to 9 parts of polyving akohol, 11 parts to 13 parts of diethylene glycol dimethyl ether and 11 parts to 13 parts of dichloroethane. The paint materials are ester gum varnish. The antirust drawing oil can meet the requirement for lubricating during stamping and can also meet the antirust requirement.

Description

technical field [0001] The invention relates to the technical field of air-conditioning sheet metal parts, and more specifically relates to an antirust deep drawing oil for air-conditioning sheet metal parts. Background technique [0002] When air-conditioning sheet metal products are stamped (such as deep drawing, bending, etc.), it is necessary to apply drawing oil on the workpiece and mold to play a lubricating role to prevent wear of the mold and workpiece, and prevent defects such as pull-through of the workpiece. Ordinary deep drawing oil has no anti-rust effect, and the workpiece is easy to rust in hot and humid weather. Most air-conditioning sheet metal products need to be electroplated. Even if the rust is removed after rusting, spots will be left on the surface of the workpiece, which not only affects the appearance, but also affects the antirust performance of the workpiece after electroplating. At present, anti-rust water is mainly used for anti-rust. After the ...
