Example Embodiment

[0027] Example 1

[0028] A preparation method of hydrocarbon-based grease for surface protection of steel wire ropes, including the following steps: First, 480g of base oil (naphthenic oil, kinematic viscosity at 100°C is 15.5mm) 2 / s) Put it into the kettle, heat up to about 120℃, put in 200g thickener APP until it is completely melted, keep the material temperature in the range of 130~140℃, keep it for about 10min, then put in 160g microcrystalline wax (70#, drop melting point At 67°C) to all dissolve, keep for about 60min. Then add 3.5g alkyl diphenylamine (petrochemical product name code T557), 16g barium petroleum sulfonate, 16g lanolin calcium soap to dissolve all of them, and stir at this temperature for about 60 minutes, and naturally cool to below 90℃ You can get out of the kettle. Its performance is listed 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...
