[0019] The preparation method of high-efficiency corrosion inhibitor is:

[0020] (1) Put N-methylpyrrolidone and polymethacrylate into the reactor at a mass ratio of 10-12:3, use nitrogen protection, preheat at 35-40°C for 30 minutes, and then add tetraethyl hydrogen Ammonium oxide solution, heated to 70-80°C for 3 hours;

[0021] (2) After the reaction is completed, rotary evaporate and collect the residue. In parts by weight, take 100-120 parts of dimethyl sulfoxide, 30-35 parts of the residue, 10-15 parts of methacryloyl ethyl Put sulfobetaine and 2-5 parts of sodium persulfate into the reactor, use nitrogen protection, heat up to 105-110°C, graft reaction for 8 hours, discharge, vacuum evaporate to remove dimethyl sulfoxide, and collect the residue , that is, a high-efficiency sustained-release complex.

[0022] The additive is prepared by ball milling nano silicon dioxide and carbon nanotubes in a mass ratio of 7-9:1-3.

[0023] The synergist is made by mixing sodium ...

Abstract

The invention belongs to the technical field of metal surface treatment and particularly relates to salt spray resisting type antirust oil. The salt spray resisting type antirust oil selects hydrogen-containing silicone oil, linseed oil and light diesel oil as base oil, so that the film forming performance and an antiseptic effect of the antirust oil can be effectively improved; meanwhile, polymethacrylate and tetraethylammonium hydroxide undergo amidation reaction and then a reacted product and methacryloxyethyl sulfobetaine undergo polymerization reaction under the initiating action of sodium persulfate to form an amphiphilic polymer; the amphiphilic polymer can be effectively bonded with a metal matrix, and hydrophobic groups form a protective film on the outer side; meanwhile, the formation of a polymer improves the salt spray resistance and the corrosion resistance; in addition, additives are added for effectively adsorbing metal ions and avoiding the corrosion to metal substrates; besides, the additives and hydrophobic groups are bonded and are arranged on the outer side, so that the salt spray resistance of the antirust oil is further improved.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a salt spray-resistant antirust oil. 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. In order to avoid corrosion and reduce losses, people have adopted various methods, such as using antirust 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 sealing of steel, copper, aluminum, galvanized, cadmium and other metal parts and their assemblies. However, the anti-rust oil with a long anti-rust perio...
