At present, the wheel-rail lubrication that generally adopts mainly is lubricating oil, lubricating grease.It is lubricated that this series lubricant agent is actually a kind of liquid oil film.They are fluid and semi-fluid condition usually, require coating unit accurate oiling position must be arranged and be coated with the oil mass function accurately during use, could guarantee not have unnecessary grease and enter the wheel track rolling surface.For this reason, various countries have done many work, and a series of new and high technologies such as hydrostatic control, computer, sun power have all been used on the oiling station.Although said apparatus more complicated, price height, manipulate inconvenience, can only to be used for vehicle-mounted wheel flange lubricating and ground rail lubricated, wants further to improve the wheel-rail lubricating effect, must make oiling station easy and to implement the vehicular rail lubricated.
Occurred a kind of solid lubricant in recent years, it is to be equipped with various property-modifying additives and filler is made with the good especially tetrafluoroethylene of self lubricity, and it is convenient to apply when it uses, and is easy to control.But one of maximum characteristic of tetrafluoroethylene be difficult to other material adhesive together, therefore, be difficult to be attached to the stable lubricant film of formation on the wheel-rail lubricating face and bring into play the function of wheel-rail lubrication.
The purpose of this invention is to provide a kind of wheel-rail lubricating material between liquid lubrication film and solid lubricant film, this material can form stable lubricant film to the strong adhesion of wheel track, and applies easy, coated weight and position are easy to control, and it is lubricated particularly to implement the vehicular rail.
The object of the present invention is achieved like this: prepare and a kind ofly make carrier with paraffin, add the composite lubricated material that intensity improvement agent, extreme pressure antifriction additive form.Be solid-state under this material normal temperature, metal is had stronger sticking power, make the rod of similar wax crayon, can be at the trackside lines that draw.When wheel on rail, press out-of-date, wheel-rail friction point moment Sheng Rekeda high temperature more than 80 ℃, this will make after this matrix material fusing equably on the corresponding position attached to trackside, the effect of performance wheel-rail lubricating.Like this, coating procedure is very simple: rail and lubricant relative movement can realize, and this lubricant can be owing to speed of a motor vehicle variation, Vehicular vibration are supplied too much or sputter.Like this, vehicle-mounted rail is applied become simple, do not need to design especially complex appts, traditional vehicle-mounted wheel flange lubricating and the lubricated vehicular rail that becomes of ground rail are lubricated, lubricant effect improves greatly.
Concrete Recipe of the present invention is as follows: (weight percentage)
Solid paraffin: (5-80 ℃ of fusing points): 60-90%
Polyolefine:
(intermediate molecular weight) 1-10%
Anti-friction composition: 5-30%
Content is important component part of the present invention at 5-30% low friction compound, it is the lubricated main body of antifriction, mainly comprises following material: graphite, molybdenumdisulphide, dialkyl dithio amido formate series (DTC salt), olefine sulfide (T405) or sulfurized fatty, organophosphate, alkyl-thio-phosphate, lead naphthenate etc.For example, zinc dialkyl dithiophosphate (T20) sulphur phosphorus is for stearylamine salt (T305).
Solid paraffin is the general name of refined white wax, white paraffin (industrial paraffin), yellow wax (common paraffin), ceresine (Microcrystalline Wax), belongs to the natural oil series product, and it is solid-state that normal temperature is, and fusing is in a liquid state in the time of 50-80 ℃.Because good, the non-corrosiveness of chemical stability, good with multiple organism intermiscibility, to the metal strong adhesion, be lubricant be again good dispersant and carrier.Adding 1-10% polyolefine is in order to improve its structural strength.Graphite is a kind of typical solid lubricant, its molecule stratiform structures shape its good lubrication is arranged, chemical reaction does not take place with the metallic surface in itself, but forms one deck barrier film in the metallic surface.It and metallic surface bonding force are relatively poor, must rely on paraffin and just can give full play to antifriction function as carrier.
Molybdenumdisulphide, sulfurized fatty or olefine sulfide (T405) dialkyl dithio amido formate series, (DTC salt), this class sulfidic material can be adsorbed rapidly in the metallic surface, then by a series of physicochemical change, form the dystectic iron sulphide sealing coat of one deck in the metallic surface, improve the carry load ability of lubricant greatly.
Rapid and the metallic surface effect generation iron phosphide chemical films of organophosphate energy, this class material is softer, and the pit that can fill up the microcosmic of metallic surface makes surface smoothing and reaches antifriction function.The advantage that the organosulfur phosphorus compound has aforementioned phosphorus compound and sulphur compound concurrently is that skeleton (hard fulcrum) phosphide is filled and led up the composite isolated film of pit at metallic surface formation sulfide, reaches more effective friction reducing effect.This class material mainly contains zinc dialkyl dithiophosphate (T20), and sulphur phosphorus is for stearylamine salt (T305).
Organometallics, as lead naphthenate and aforementioned DTC salt, metallic element is in the tribo-chemistry process in this class material, attached to playing the barrier film effect in the fastness surface, object point still can be had an effect when the friction point temperature is very high will to produce metallic residue (being generally soft metals such as lead, antimony, zinc, molybdenum).
