Example Embodiment

[0028] Example 1

[0029] Use light refined oil as base oil. In the production process, first add 66.37kg of light refined oil to the reactor and stir; add 10kg anti-rust compound 1, 10kg anti-rust compound 2, 12kg anti-rust compound 3 and continue stirring for 25-35 minutes; Add 0.08kg stearic acid, 0.5kg antioxidant compound and 0.05kg anti-rust compound 4 successively, and continue to stir for 25-35 minutes; finally add 1kg surfactant and continue stirring for 80-120 minutes to obtain a thin layer of rust preventive oil.

Example Embodiment

[0030] Example 2

[0031] Use light refined oil as base oil. In the production process, first add 65kg of light refined oil to the reactor and stir; add 9.5kg of anti-rust compound 1, 11kg of anti-rust compound 2, 13kg of anti-rust compound 3 and continue to stir for 25-35 minutes; Add 0.06kg stearic acid, 0.6kg antioxidant compound and 0.04kg anti-rust compound 4 in sequence, continue to stir for 25-35 minutes; finally add 0.8kg surfactant and continue stirring for 80-120 minutes to obtain a thin layer of rust preventive oil.

Example Embodiment

[0032] Example 3

[0033] Use light refined oil as base oil. In the production process, first add 67kg of light refined oil to the reaction kettle and stir; add 11kg anti-rust compound 1, 9kg anti-rust compound 2, 11.2kg anti-rust compound 3 and continue to stir for 25-35 minutes; Add 0.1kg stearic acid, 0.42kg antioxidant compound and 0.08kg anti-rust compound 4 successively, and continue to stir for 25-35 minutes; finally add 1.2kg surfactant and continue stirring for 80-120 minutes to obtain a thin layer of rust preventive oil.

[0034] In the embodiment of the present invention, the light refined oil is No. 5 white oil, which is a commercially available product, purchased from Ningbo Zhenhai Oil Refinery. The surfactant is Span-80. The anti-rust compound 1 is a mixture of barium petroleum sulfonate and No. 5 mechanical oil, where barium petroleum sulfonate accounts for 40% of the total weight of the mixture, and No. 5 mechanical oil accounts for 60% of the total weight of the...

Abstract

The invention discloses thin-layer antirust oil. The oil contains 65-67wt% of lightweight refined oil, 9-11wt% of antirust compounding agent 1, 9-11wt% of antirust compounding agent 2, 10-14wt% of antirust compounding agent 3, 0.02-0.08wt% of antirust compounding agent 4, 0.06-0.1wt% of stearic acid, 0.4-0.6wt% of antioxidation compounding agent and 0.8-1.2wt% of surfactant. A preparation method of the thin-layer antirust oil comprises the following steps: adding the lightweight refined oil to a reactor and stirring the lightweight refined oil; adding the antirust compounding agent 1, the antirust compounding agent 2 and the antirust compounding agent 3 to the reactor in sequence and continuously stirring the mixture for 25-35 minutes; then adding the stearic acid, the antioxidant and theantirust compounding agent 4 to the reactor in sequence and continuously stirring the mixture for 25-35 minutes; and then adding the surfactant to the reactor and continuously stirring the mixture for 80-120 minutes, thus obtaining the thin-layer antirust oil. The thin-layer antirust oil has the following advantages: the production process of the antirust oil is simple; the antirust oil is non-toxic and harmless, has excellent moisture and heat resistance and salt mist resistance and can be sprayed, brushed or dipped on the parts; and the antirust oil has thin coating, so the parts with the antirust oil can be assembled without cleaning the antirust oil.

Description

technical field [0001] The invention relates to a thin-layer 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. 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 period will easily produce a thicker oil film after the par...
