A metal antirust oil containing tripolyglycerol monostearate

Abstract

The invention discloses metal rust-preventative oil containing trimerization glycerol monostearate. The metal rust-preventative oil containing the trimerization glycerol monostearate comprises the following raw materials, by weight, 0.2 part-0.3 part of zinc naphthenate, 0.4 part-0.6 part of benzotriazole, 1.3 parts-1.6 parts of 2-aminoethyl-heptadecenyl-imidazoline, 105 parts-115 parts of number 120 solvent oil, 1 part-2 parts of methacrylic acid isobutyl ester, 1.2 parts-2.4 parts of a silane coupling agent KH540, 1.5 parts-2.7 parts of lanolin magnesium soap, 0.5 part-0.7 part of petroleum barium sulfonate, 0.5 part-0.7 part of antioxidant BHT, 0.6 part-0.8 part of alcohol ether glucoside, 0.4 part-0.6 part of oleic acid triethanolamine, 1.1 parts-1.4 parts of the trimerization glycerol monostearate, 0.4 part-0.5 part of carbinol, 0.2 part-0.4 part of a silane coupling agent KH550, 6 parts-8 parts of composite film-forming materials, 0.3 part-0.5 part of modified nanometer potassium feldspar powder, and 0.1 part-0.2 part of antioxidant 626. The metal rust-preventative oil containing the trimerization glycerol monostearate has good contact rust-preventative performance and a good gaseous phase rust-preventative effect. The metal rust-preventative oil containing the trimerization glycerol monostearate has the good gaseous phase rust-preventative effect and a contact rust-preventative effect to steel and brass.

Description

technical field [0001] The invention relates to the field of metal surface treatment agents, in particular to a metal antirust oil containing tripolyglycerol monostearate. Background technique [0002] Metal surface treatment agent refers to the general term for various chemical agents for metal surface treatment. Metal surface treatment includes degreasing, rust removal, phosphating, antirust and other substrate pretreatments, which are prepared for metal coating technology and metal protection technology. The quality of substrate pretreatment has a great influence on subsequent coating preparation and metal use. big impact. [0003] Oil-soluble rust inhibitors are also called oil-soluble corrosion inhibitors. Most are long carbon chain organic compounds with polar groups. The polar groups in the molecule are tightly adsorbed on the metal surface by the action of charge; the non-polar group long carbon chain hydrocarbons are facing the outside of the metal surface, and c...

Problems solved by technology

However, the anti-rust effect of simple amines in mineral oil is not good enough, and amine salts or other compounds formed by amines and organic acids are commonly used, such as octadecylamine oleate, cyclohexylamine stearate, etc.
