Abstract

The invention discloses electrostatic spraying slushing oil. The electrostatic spraying slushing oil is composed of the following raw materials in parts by weight: 0.4-1 part of p-nitrophenyl phosphate sodium, 60-70 parts of #25 transformer oil, 1-2 parts of polyisobutene, 3-5 parts of microcrystalline wax, 2-3 parts of hosho oil, 2-4 parts of phthalate polyester, 4-6 parts of petroleum sodium sulfonate, 2-3 parts of fumed silica, 1-3 parts of triethanolamine oleic soap, 1-2 parts of diphenyl silandiol, 0.5-1 part of monopotassium phosphate, 0.4-1 part of inositol hexaphosphoric acid, 0.3-0.5 part of zinc acetylacetonate, 2-3 parts of oleic acid and 3-5 parts of wear resistant machine oil. A molecular directional adsorption film can be formed on the surface of the metal by adding the wear resistant machine oil into the slushing oil, so that the friction can be reduced; the modified terpene resin has a good cohesive property and strong thermal stability so that the compatibility between the materials can be promoted and the adhesive force of the film can be enhanced; the zinc dihydrogen phosphate is used as a common metal surfactant which has a good rust removal preservative effect; the rare earth lanthanum ion and the OH<-> generated on the surface of the metal material during the oxygen absorption corrosion process can generate an insoluble complex which can slow down the corrosion of the electrode reaction and has a good slow-release effect.
