experiment example

[0024] Experimental example: Comparative example when conductive polyaniline is not added in the technical scheme of the present invention:

[0025] Weigh 350g of No. 46 engine oil, add 100g of sodium stearate to the engine oil, heat and stir at a heating temperature of 140°C, and stir at constant temperature for 1 hour to completely melt the lithium stearate in the engine oil, stop heating, and cool to room temperature.

[0026] Measure 15g of barium petroleum sulfonate, 2.5g of N-phenyl-α-naphthylamine, and 3g of sulfided dibutene slowly into the above grease, and continue to stir for 1 hour, and stir evenly.

[0027] Grind the mixed grease on a cone mill repeatedly for 2 hours. The above-mentioned anti-rust grease was coated on the surface-treated low-carbon steel plate, the thickness was controlled to 100μm, and the ASTM B117 international standard salt spray test was used. The sample plate began to rust severely within 150 hours.

Embodiment 1

[0029] Weigh 350g of No. 46 engine oil, add 100g of sodium stearate to the engine oil, heat and stir at a heating temperature of 140°C, stir at constant temperature for 1 hour, so that the sodium stearate is completely melted in the engine oil, stop heating, and cool to room temperature.

[0030] Weigh 2g of dodecylbenzenesulfonic acid doped conductive polyaniline powder, slowly add the polyaniline powder to the above mixed oil under mechanical stirring, mechanically stir at 1600 rpm for 2 hours, and heat at 80°C to make it conductive Polyaniline is dispersed in the grease at nanometer level and cooled to room temperature.

[0031] Measure 10g of barium petroleum sulfonate, 2.5g of N-phenyl-α-naphthylamine, and 3g of sulfided dipolybutene slowly into the above grease, and continue to mechanically stir at 1600 rpm for 1 hour, and stir evenly.

[0032] Grind the mixed grease on a cone mill repeatedly for 2 hours. The above-mentioned anti-rust grease was coated on the surface-treated...

Embodiment 2

[0034] Weigh 350g of No. 46 engine oil, add 100g of lithium stearate to the engine oil, heat and stir at 170°C, stir at constant temperature for 1.5 hours, so that the lithium stearate is completely melted in the engine oil, stop heating, and cool to room temperature.

[0035] Weigh 2g of dodecylbenzenesulfonic acid doped conductive polyaniline, slowly add the conductive polyaniline powder to the above mixed oil under mechanical stirring, stir at 1700 rpm for 3 hours, and heat at 50°C to make the conductive polyaniline Aniline reaches nano-level dispersion in grease. Then cool to room temperature.

[0036] Measure 10g of sodium petroleum sulfonate, 16g of lanolin, 2.5g of N-phenyl-α-naphthylamine, and 3g of sulfurized dipolybutene slowly into the above grease, and continue to stir at 1700 rpm for 1 hour, and stir evenly .

[0037] Grind the mixed grease on a cone mill repeatedly for 3 hours. Coating the above-mentioned anti-rust grease on the surface-treated low-carbon steel plate...

Abstract

This invention involves a kind of conductive high polymer high temperature lubricant and preparing method. Made up by the following raw materials according to the ratio by weight: Basic oil is 50%- 90%, soap base thicken pharmaceutical 5% - 30%, conductive high polymer 0.1% - 10%, antirust additive 0.1% - 10%, resist oxygen additive 0.1% - 10%, resist and rub additive 0.1% - 10%.Is it mix attitude electric conduction gather aniline lose the pharmaceutical slowly as subject, conduct and gather aniline, basic oil to adopt. Thick to take pharmaceutical , rust inhibitor , resist oxygen pharmaceutical , is it rub pharmaceutical ,etc. additive mix altogether to resist, do not add any solute , through the craft of heating , mixing , grinding etc., the scattering of making the electric conduction gather the aniline and reach the nanometer grade in the basic oil. Its advantage lies in that it is acid and alkaline resisting, suitable for using under very abominable environmental condition such as being acid or alkaline, and especially suitable for the marine environment for antiseptic.

Description

Technical field [0001] The invention relates to an anti-rust lubricating grease, and the invention also relates to a preparation method of the anti-rust lubricating grease. technical background [0002] As a new type of polymer material, conductive polymer has been used in many fields, especially in metal anti-corrosion coatings, showing its excellent characteristics. For example, the Wassling research group in Germany first reported the research on conductive polyaniline anticorrosive coating in 1994, and it has been industrialized and put on the market. The Changchun Institute of Applied Chemistry, Chinese Academy of Sciences has obtained results in the research of "polyaniline anticorrosive grease". , Has declared a patent. But it uses intrinsic state polyaniline, without adding any solvent, the intrinsic state polyaniline powder is blended into grease by mechanical grinding method. Because polyaniline is a high-molecular polymer, the special structure of this polymer makes it...
