[0011] 2. Film weight
[0021] When phosphating metal is to be stored for long-term anti-rust, if liquid anti-rust (anti-rust water, anti-rust oil) is used, the liquid will penetrate into Fe 3 o 4 Under the protective layer, it causes phosphoric acid surface rust, and the liquid floats out of the metal surface, causing metal rust

Abstract

The invention discloses phosphated metal rust-proof oil, comprising the following components: 10-15 parts of antirust agent 1, 1-3 parts of antirust agent 2, 2-8 parts of soap, 20-30 parts of stabilizer, and 50-60 parts of cosolvent. The invention also discloses a preparation method of the phosphated metal rust-proof oil. The phosphated metal rust-proof oil can rapidly form a semi-solid mucosal rust protective layer on the metal surface within 3-5 minutes according to the characteristics of phosphated metal; meanwhile, contact of metal with oxygen and steam in the air is blocked, so as to play an effective rust protection effect on phosphated metal.

Description

technical field [0001] The invention relates to an antirust oil and a preparation method thereof, in particular to a phosphating metal antirust oil and a preparation method thereof. Background technique [0002] Corrosion is one of the main forms of damage to fasteners, and it will cause great losses to automobiles, motorcycles and various vehicles and machinery. According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2% to 4% of the total output value of the national economy. [0003] In order to avoid corrosion and reduce losses, people have adopted various methods, and the commonly used surface chemical transformation methods are oxidation, phosphating, and passivation. [0004] Such as the use of anti-rust oil. Anti-rust oil is a kind of lubricating oil. It is an oil solvent with anti-rust function. It is composed of base oil and auxiliary additives. Widely used in the indoor process of rust prevention or packaging and sea...
