Embodiment 1

[0028] A kind of preparation method of the hydrocarbon-based lubricating grease that is used for steel wire rope surface protection, comprises the steps: first with 480g base oil (naphthenic oil, 100 ℃ kinematic viscosity is 15.5mm 2 / s) into the kettle, heat up to about 120°C, put in 200g of thickener APP until completely melted, maintain the temperature of the material in the range of 130-140°C, keep it for about 10min, then put in 160g of microcrystalline wax (70#, drop melting point 67°C) to completely dissolve and keep for about 60 minutes. Then add 3.5g of alkyl diphenylamine (petrochemical product name code T557), 16g of barium petroleum sulfonate, and 16g of lanolin calcium soap in order to dissolve them all, and stir at this temperature for about 60min, and naturally cool down to below 90°C It can be taken out of the kettle. List its performance in Table 1.

Embodiment 2

[0030] A kind of preparation method of the hydrocarbon-based lubricating grease that is used for steel wire rope surface protection, comprises the steps: first with 480g base oil (naphthenic oil, 100 ℃ kinematic viscosity is 15.5mm 2 / s) into the kettle, heat up to about 150°C, put in 200g of thickener APAO until completely melted, keep the temperature of the material in the range of 140-150°C, keep it for about 10min, then put in 160g of microcrystalline wax (70#, drop melting point 67°C) to completely dissolve and keep for about 60 minutes. Then add 3.5g of alkyl diphenylamine (petrochemical product name code T557), 16g of barium petroleum sulfonate, and 16g of lanolin calcium soap in order to dissolve them all, and stir at this temperature for about 60min, and naturally cool down to below 90°C It can be taken out of the kettle. List its performance in Table 1.

Embodiment 3

[0032] A kind of preparation method of the hydrocarbon-based lubricating grease that is used for steel wire rope surface protection, comprises the steps: first with 480g base oil (paraffin base oil, 100 ℃ kinematic viscosity is 35.5mm 2 / s) into the kettle, heat up to about 120°C, put in 200g of thickener APP until completely melted, keep the temperature of the material in the range of 130-140°C, keep it for about 10min, then put in 160g of microcrystalline wax (85#, drop melting point 83°C) to completely dissolve and keep for about 60 minutes. Then add 3.5g of alkyl diphenylamine (petrochemical product name code T557), 16g of barium petroleum sulfonate, and 16g of lanolin calcium soap in order to dissolve them all, and stir at this temperature for about 60min, and naturally cool down to below 90°C It can be taken out of the kettle. List its performance in Table 1.

Abstract

The invention relates to alkyl lubricating grease used for surface protection of a steel wire rope and a preparation method thereof. The alkyl lubricating grease comprises the following components by weight: 52.0-78.0% of base oil, 10.0-35.0% of microcrystalline wax, 8.0-30.0% of thickener, 0.25-0.6% of alkyl diphenylamine, 1.5-3.0% of petroleum barium sulfonate and 1.5%-3.0% of lanolin calcium soap. The sum of the weight percentages is 100%. The moving viscosity of the base oil under 100 DEG C is 10.0-40.0 mm2 / s, the thickener is ammonium polyphosphate (APP) or amorphous poly alpha olefin (APAO), and the dropping melting point of the microcrystalline wax is 65-85 DEG C. The APP or the APAO is utilized as the thickener, dropping point of the alkyl lubricating grease is improved, adhesion performance of the alkyl lubricating grease is improved, and antirust performance and anti-corrosion performance of the alkyl lubricating grease are excellent.

Description

technical field [0001] The invention relates to a lubricating grease, in particular to a hydrocarbon-based lubricating grease used for steel wire rope surface protection and a preparation method thereof. Background technique [0002] Steel wire rope surface grease is a kind of lubricating grease coated on the surface of strands and twisted steel wire ropes. On the one hand, its function is to reduce the friction between the steel wires in the strands and the friction between the steel wire rope and the sheave groove during the use of the steel wire rope, so as to reduce the friction of the steel wire rope. wear; on the other hand, it protects the wire rope from corrosion during transportation, storage and use. This requires the steel wire rope surface grease products to have the following properties: excellent adhesion, permeability, good anti-rust, anti-corrosion properties and good extrusion and anti-wear properties. [0003] Wire rope surface grease can be divided into d...
