Problems solved by technology

The existing anti-rust oil corrosion inhibitors are almost all water-soluble; and oil-soluble corrosion inhibitors cannot be formulated into electrolyte solutions because they are insoluble in water, so it is difficult to use electrochemical methods to perform anti-rust oil corrosion by polarization curve method. Accurate assessment

preparation example Construction

[0027] The preparation method of the above-mentioned emulsified antirust oil comprises the following steps in sequence: (a) adding the polymaleic anhydride in the formula amount into the naphthenic base oil in the formula amount, heating to 40-45°C, and stirring until dissolved Then stop heating; (b) continue to add the described triethanolamine of formula quantity wherein, stir 30~40 minutes; When temperature drops to room temperature, add the raw material of other formula quantity, add the deionized water of formula quantity after stirring and dissolving, then Just mix well. Mix polymaleic anhydride and naphthenic base oil evenly under heating conditions, add triethanolamine and stir for 30 to 40 minutes, and then add other ingredients, so as to ensure good compatibility of emulsified antirust oil components, and finally ensure its Antirust and emulsifying properties.

[0028] In the step (b), when the temperature drops to room temperature, add the sodium petroleum sulfonat...

Embodiment 1

[0031] The present embodiment provides an emulsified antirust oil, which is composed of the following components by weight percentage: 5 kg of sodium petroleum sulfonate; 5 kg of barium petroleum sulfonate; 3 kg of sodium dodecenyl succinate; 1 kg of polymaleic anhydride; Triethanolamine 3kg; benzotriazole 0.1kg; C16 fatty alcohol polyoxyethylene ether carboxylic acid 2kg; isomeric C13 fatty alcohol polyoxyethylene ether 5kg; diethylene glycol monobutyl ether 1kg; 2kg; water 2kg; the balance is naphthenic base oil.

[0032] The preparation method is as follows: (a) Add 1 kg of polymaleic anhydride (molecular weight: 1000) into 70.9 kg of naphthenic base oil, heat to 40°C, stir until dissolved, and then stop heating;

[0033] (b) Continue to add 3kg of triethanolamine to it, stir for 30 minutes, and dissolve evenly; when the temperature drops to 25°C, add 5kg of sodium petroleum sulfonate, 5kg of barium petroleum sulfonate, 3kg of sodium dodecenylsuccinate, 0.1 kg benzotriazol...

Embodiment 2

[0035] The present embodiment provides an emulsified antirust oil, which is composed of the following components by weight percentage: 10 kg of sodium petroleum sulfonate; 10 kg of barium petroleum sulfonate; 6 kg of sodium dodecenyl succinate; 3 kg of polymaleic anhydride; Triethanolamine 5kg; Benzotriazole 1kg; C18 fatty alcohol polyoxyethylene ether carboxylic acid 5kg; Isomerized C13 fatty alcohol polyoxyethylene ether 10kg; Diethylene glycol monobutyl ether 5kg; Sorbitan monooleate 5kg ; Water 5kg; The remainder is naphthenic base oil. The preparation method is consistent with that in Example 1.

Abstract

The invention relates to an emulsified rust prevention oil and a preparation method thereof. The emulsified rust prevention oil comprises, by weight, 5-10% of sodium petroleum sulfonate, 5-10% of barium petroleum sulfonate, 3-6% of sodium dodecenyl succinate, 1-3% of polymaleic anhydride, 3-5% of triethanolamine, 0.1-1% of benzotriazole, 2-5% of fatty alcohol polyoxyethylene ether carboxylic acid, 5-10% of isomeric fatty alcohol polyoxyethylene ether, 1-5% of diethylene glycol monobutyl ether, 2-5% of sorbitan monooleate, 2-5% of water, and the balance of naphthenic base oil; and the molecular weight of the polymaleic anhydride is 1000, the quantity of carbon atoms in the fatty alcohol group of the fatty alcohol polyoxyethylene ether carboxylic acid is 16-18, and the quantity of carbon atoms in the isomeric fatty alcohol group of the isomeric fatty alcohol polyoxyethylene ether is 13. An oil-soluble corrosion inhibitor composed of naphthenic base oil, the sodium petroleum sulfonate, the barium petroleum sulfonate and triethanolamine is compounded with maleic anhydride, fatty alcohol polyoxyethylene ether carboxylic acid and the isomeric fatty alcohol polyoxyethylene ether to make the above materials be dissolved in water in order to form an electrolyte solution, so accurate evaluation of rust prevention oil is carried out through a polarization curve technology is realized, and a surprising effect is generated; and the emulsified rust prevention oil obtained after compounding has good rust prevention and emulsification performances.

Description

technical field [0001] The invention belongs to the field of metal anticorrosion, and relates to an antirust oil, in particular to an emulsified antirust oil and a preparation method thereof. Background technique [0002] Metal is the most important structural material in modern machinery industry, national defense industry, petroleum industry and other departments, but it is easily deteriorated or damaged by the chemical and electrochemical effects of the external environment or medium (this is metal corrosion). Corrosion is one of the main forms of material damage, causing great losses to various departments in the national economy and national defense construction. According to the statistics of some developed countries, the direct economic loss caused by metal corrosion accounts for about 2% to 4% of the total output value of the national economy every year, at least more than 10 billion yuan, and its harm is also very alarming. In order to avoid corrosion and reduce lo...
