Abstract

The invention relates to a preparation method of hard film anti-rust oil with high hardness and belongs to the technical field of anti-rust oil. The method comprises the following steps: uniformly stirring light diesel oil, beeswax, turpentine, sunflower seeds, poly oxidation alkyl glycol, ricinus oil oxypropylene polymer, triethanolamine, ceresin wax, ethyl acetate and a non-ionic surfactant, heating, preserving heat and stirring uniformly to obtain a first mixture; adding petroleum barium sulfonate into ethylene glycol, adding diethylene glycol, kerosene and styrene-acrylic emulsion in sequence, heating, preserving heat and stirring uniformly to obtain a second mixture; mixing the first mixture and the second mixture, adding an antifoaming agent, an antioxygen, a thixotropic agent, an anti-rust agent and stirring uniformly. The anti-rust oil provided by the invention is better in hardness and anti-rust performance.

Description

[0001] technical field [0002] The invention relates to a preparation method of dura-film antirust oil with high hardness, belonging to the technical field of antirust oil. [0003] Background technique [0004] Anti-rust oil is an oil with anti-rust function, which is composed of oil-soluble corrosion inhibitor, base oil and auxiliary additives. According to performance and use, it can be divided into fingerprint removal type antirust oil, water dilution type antirust oil, solvent dilution type antirust oil, antirust and lubrication dual-purpose oil, sealed antirust oil, replacement type antirust oil, thin layer oil , antirust grease and vapor phase antirust oil, etc. Corrosion inhibitors commonly used in antirust oils are alkaline earth metal salts of fatty acids or naphthenic acids, lead naphthenate, zinc naphthenate, sodium petroleum sulfonate, barium petroleum sulfonate, calcium petroleum sulfonate, tallow trioleate Amine, rosin amine, sorbitan monooleate, polyethy...
