experiment example

[0024] Experimental example: comparative example when no conductive polyaniline is added in the technical solution of the present invention:

[0025] Weigh 350g of No. 46 engine oil, add 100g of sodium stearate into the engine oil, heat and stir at a temperature of 140°C, and stir at a 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 dibutylene sulfide, and slowly add them to the above oil, and continue to stir for 1 hour until uniform.

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

Embodiment 1

[0029] Weigh 350g of No. 46 engine oil, add 100g of sodium stearate into the engine oil, heat and stir at a temperature of 140°C, and stir at a constant temperature for 1 hour to completely melt the sodium stearate 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 conductive Polyaniline is dispersed in nanoscale in oil and cooled to room temperature.

[0031] Measure 10g of barium petroleum sulfonate, 2.5g of N-phenyl-α-naphthylamine, and 3g of dibutylene sulfide slowly into the above oil, and continue to mechanically stir at 1600 rpm for 1 hour until uniform.

[0032] Grind the mixed oil repeatedly on a cone mill for 2 hours. The above-mentioned anti-rust grease was coated on the surface-treated low-carbon steel plate, and the t...

Embodiment 2

[0034] Weigh 350g of No. 46 engine oil, add 100g of lithium stearate into the engine oil, heat and stir at a temperature of 170°C, and stir at a constant temperature for 1.5 hours to completely melt the lithium stearate 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 for 3 hours at 1700 rpm, and heat at 50°C to make the conductive polyaniline Aniline achieves nanoscale dispersion in oil. 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 dibutylene into the above oil, and continue to stir at 1700 rpm for 1 hour, stirring evenly .

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

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 antirust lubricating grease, and also relates to a preparation method of the antirust lubricating grease. technical background [0002] Conductive polymer, as a new type of polymer material, has been applied in many fields, especially in metal anti-corrosion coatings, showing its excellent characteristics. For example, the WassIing research group in Germany first reported the research on conductive polyaniline anti-corrosion coatings in 1994, and it has been industrialized and introduced to the market. The Changchun Institute of Applied Chemistry, Chinese Academy of Sciences has achieved results in the research of "polyaniline anti-corrosion grease". , has declared a patent. But what it adopts is the intrinsic state polyaniline, and under the situation of not adding any solvent, the intrinsic state polyaniline powder is blended into the grease by mechanical grinding method. Because polyaniline is a high molecular polymer, ...
