Description
Technical field
The present invention relates to a kind of lubricating grease, particularly relate to a kind of high-temperature-resistant steel wire rope surfacecti proteon lubricating grease.
Background technology
Wireline is the flexible cable twisted into many or multiply light gage wire, and wireline is twisted stock by multilayer steel wire, then centered by wire rope core, twist with the fingers helically wound rope by some amount stock.Wireline can by shape, level, and the modes such as state are classified.Round-strand rope, braided wire rope and band rope is divided into by shape; Wireline by twist around level can be divided into single wiring, double wrap rope and three wirings; Wireline also can be divided into point cantact, linear contact lay or face to contact 3 kinds by the contact condition in stock between every layer of steel wire.In material carrying machine, for promoting, traction, tension and carrying.The intensity of wireline is high, from heavy and light, stable working, not easily whole root fracture suddenly, reliable operation.
Wire-rope grease is by organic viscosifying agent group and high viscosity oil petroleum refined by naphthenic, and is added with the wirerope lubricating grease that the multiple additives such as anti-oxidant, protection against corrosion, rust protection, anti-extreme pressure refine.Wire rope surface grease can be divided into hydrocarbon-based type wire rope surface grease, pitch shaped steel wire rope face grease, soap base type lubricating grease etc. dissimilar by its composition.Hydrocarbon-based type wire rope surface grease, general adopts the preparation of waste and old paraffin, ceresine, and dropping point is lower, use temperature scope at about 45 ~ 55 DEG C, large usage quantity.
Wire rope surface grease is a kind of lubricating grease being coated on stock He being twisted rear wireline surface, and its effect is on the one hand reduce the friction of wireline in use in stock between steel wire and the friction of wireline and rope sheave groove, to reduce the wearing and tearing of wireline; That protection wireline is not corroded in transport, storage and use procedure on the other hand.This just requires that wire rope surface grease product has following performance: excellent adhesion, penetrating quality, good antirust, Corrosion Protection and good extruding abrasion resistance.Some scholars attempt in the basic fat of hydrocarbon-based type wire rope surface grease, adding various additive to improve its adhesion, high temperature performance, and achieve certain effect.Zhu Li etc. add enhancing resin, viscosity-controlling agent etc. on paraffinic base grease base plinth, and hydrocarbon-based type wire rope surface grease can be made after depositing 3 months summer not occur drip phenomenon.Ling Weihong, ginger and base etc. adopt high viscosity base oil, take solid paraffin as viscosifying agent, add the high molecular polymers such as polyvinyl paraffin wax, resol, petroleum resin and improve its high temperature performance.
As CN102250670A discloses a kind of special lubricating grease composition for steel wire rope.Composition and the percentage composition of its composition are as follows: (1) 12-OH stearic acid lithium soap 2.0 ~ 5.2%; (2) stearic acid lithium soap 0.5 ~ 1.3%; (3) mineral base oil 53.5 ~ 76%; (4) oil 15.0 ~ 40.0% is extracted out; (5) Microcrystalline Wax 1.3 ~ 6.3%; (6) pentanoic 0.2 ~ 1.2%.CN102994198A discloses a kind of hydr ocarbon-based grease for wireline surfacecti proteon and preparation method thereof.The weight percent of each component that this hydr ocarbon-based grease comprises and each component is: base oil: 52.0 ~ 78.0%; Microcrystalline Wax: 10.0 ~ 35.0%; Thickening material: 8.0 ~ 30.0%; Alkyl diphenylamine: 0.25 ~ 0.6%; Barium mahogany sulfonate: 1.5 ~ 3.0%; Lanolin Calcium Soap: 1.5 ~ 3.0%; Above-mentioned weight percent sum is 100%; Described base oil is the kinematic viscosity of 100 DEG C is 10.0 ~ 40.0mm
2the base oil of/s, described thickening material is APP or APAO; The melt drop temperature of described Microcrystalline Wax is 65 ~ 85 DEG C.But the resistance to elevated temperatures of foregoing invention needs to be strengthened further.
Summary of the invention
