Problems solved by technology

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. Material is the most common method, and there are many problems in today's anti-rust oil, such as corrosion resistance, durability, adhesion, poor, prone to hardening, falling off, cracking, so it is necessary to continuously improve the anti-rust oil Comprehensive quality, to achieve better rust and corrosion inhibition effect

Embodiment 1

[0023] A metal pipeline antirust oil is characterized in that it is composed of the following raw materials in parts by weight (kg):

[0024] Rare earth anti-rust hydraulic oil 20, No. 20 mechanical oil 80, dimethyl chlorophthalate 3, asphalt 3, N,N-bis(2-cyanoethyl) formamide 2, polyoxyethylene stearate 2, lost Sorbitan fatty acid ester 1, methyl benzotriazole 1, zinc naphthenate 0.5, sodium pentachlorophenate 3, stannous sulfate 0.3, allyl thiourea 0.4;

[0025] Described rare earth antirust hydraulic oil is made up of the raw material of following weight part:

[0026] N-vinyl pyrrolidone 3, methyl nylon acid 2, Span80 0.7, dodecenyl succinic acid 16, hydraulic oil 110, triallyl isocyanurate 0.5, deionized water 70, potassium persulfate 0.6, Sodium hydroxide 3, cerium nitrate 4;

[0027] Mix N-vinylpyrrolidone and methyl nylonate, stir and mix at 60°C for 10 minutes to obtain esterified alkanone;

[0028] Take 80% of the weight of the above-mentioned Span80 and 50% of th...

Abstract

The invention discloses an antirust oil for metal pipelines, which is prepared from the following raw materials in parts by weight: 16-20 parts of rare-earth antirust hydraulic oil, 60-80 parts of 20# machine oil, 1-3 parts of dimethyl chlorophthalate, 3-7 parts of asphalt, 1-2 parts of N,N-bis(2-cyanoethyl)formamide, 2-3 parts of polyoxyethylene stearate, 1-2 parts of sorbitan fatty acid ester, 1-3 parts of methyl benzotriazole, 0.5-1 part of zinc naphthenate, 0.1-3 parts of santobrite, 0.3-1 part of stannous sulfate and 0.4-1 part of thiosinamine. The rare-earth antirust hydraulic oil is added into the antirust oil. The alkyl ketone dispersion solution can improve the flowability and enhance the reaction activity. The added rare-earth ions can generate an insoluble complex with OH- generated in the oxygen-absorption corrosion process on the metal substrate surface, thereby decelerating the corrosive electrode reaction and having favorable slow-release effect.

Description

[0001] technical field [0002] The invention mainly relates to the field of lubricating oil, in particular to an antirust oil for metal pipelines. Background technique [0003] During the storage, transportation and use of metals, due to the influence of water vapor, oxygen, acid, alkali, salt and carbide in the ambient atmosphere, physical and chemical changes will occur under certain temperature, humidity and time extension conditions. rust due to change. The corrosion of metal will cause the loss of metal and the decline and loss of the function of metal parts. Metal corrosion is caused by the oxidation reaction of metal in contact with moist air or electrolyte solution. Corrosion is one of the main forms of damage to fasteners, which will cause great losses to automobiles, motorcycles, 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 nati...
