Problems solved by technology

The preparation of antirust water is simple and low in cost, but the antirust paint is short and is greatly affected by the weather
The anti-rust oil has a long anti-rust period, but due to the large amount of crude oil used, the cost becomes higher
The emulsified anti-rust oil has the characteristics of the above two products. Surfactants such as triethanolamine oleate are added as emulsifiers. When used, a certain proportion of water is added to the anti-rust oil to form a uniformly dispersed emulsion. , but due to the presence of surfactants, it will absorb moisture in the air through its hydrophilic groups, making the anti-rust period shorter

Abstract

The invention discloses an antirust emulsified oil and a preparation method thereof. The antirust emulsified oil comprises: 10-15 parts of petroleum barium sulfonate, 3-7 parts of petroleum sodium sulfonate, sulfonated oil DAH? 8-15 parts, 2-6 parts of triethanolamine, 0.5-2 parts of glycerin, 0.2-0.6 parts of emulsified silicone oil, 5-10 parts of zinc naphthenate, 2-6 parts of oleic acid, 1-5 parts of sulfonated oleic acid Parts, 70-90 parts of No. 10 engine oil; the preparation method is to heat No. 10 engine oil to 80-90 ° C, and then add barium petroleum sulfonate, sodium petroleum sulfonate, triethanolamine, and zinc naphthenate under stirring conditions, and stir Evenly, to obtain a mixed solution, then lower the temperature to 50-60°C, add the remaining components, stir evenly, and cool down to room temperature to obtain anti-rust emulsified oil. It is determined that the anti-rust emulsified oil provided by the invention has good emulsification and stability performance, and the anti-rust performance can reach more than 70 days.

Description

technical field [0001] The invention belongs to the technical field of oil preparation for machinery, and in particular relates to an antirust emulsified oil and a preparation method thereof. Background technique [0002] Mechanical parts must be rust-proofed during the manufacturing process. At present, the widely used anti-rust products are anti-rust water, anti-rust oil or emulsified anti-rust oil. The antirust water is simple to prepare and low in cost, but the antirust paint is short and is greatly affected by the weather. The anti-rust oil has a long anti-rust period, but due to the large amount of crude oil used, the cost becomes higher. The emulsified anti-rust oil has the characteristics of the above two products. Surfactants such as triethanolamine oleate are added as emulsifiers. When used, a certain proportion of water is added to the anti-rust oil to form a uniformly dispersed emulsion. , but due to the presence of surfactants, it will absorb moisture in the a...
