Abstract
The invention discloses railway track screw anti-rusting lubricating grease and a preparation method thereof, and belongs to the technical field of special lubricating grease. According to the technical scheme of the invention, the railway track screw anti-rusting lubricating grease is prepared from the following raw materials in percentage by weight: 70-85% of base oil, 10-20% of a densifier, 3-4% of an additive and 2-6% of asphalt oil. The invention further specifically discloses a preparation method of the railway track screw anti-rusting lubricating grease. The lubricating grease disclosed by the invention is special railway track screw anti-rusting lubricating grease, the base oil of which the low-temperature property can be up to minus 50 DEG C is densified by using the densifier, namely, fatty acid lithium composite soap, and together with an anti-corrosion agent, an antioxidant and a pour point depressant, an excellent anti-rusting property and a relatively wide temperature use range of the lubricating grease can be ensured, and due to the added asphalt oil, the adhesion property of the lubricating grease can be improved, meanwhile as the asphalt oil has a very good air insulating property, a very good anti-rusting function can be achieved for screws.
Description
Technical field
The invention belongs to special grease technical field, and in particular to a kind of railroad track screw rust-inhibiting lubricant and its system
Preparation Method.
Background technology
Chinese Railway development speed quickly, will lay new railway every year, and the speed of train is more and more faster, bullet train
Also more and more, with the quickening of speed, the safety of train seems more important.Rail safety is also to ensure train safe operation
Key factor.Railroad track is made from multiple components, and the screw above each member tracks is each portion of connection track
The critical elements of part, it is to ensure the key factor that track is not caused danger that screw does not loosen in a long time.Keep spiral shell
Nail is firm for a long time effectively it is necessary that screw will not be corroded gets rusty.It is special it is therefore desirable to develop railroad track screw antirust
With lubricating grease, above the bolt dedicated for track all parts junction, it is ensured that bolt will not be corroded for a long time.
Chinese Regional is vast, and temperature has a long way to go, and influence of the temperature to lubricating grease is very big, and this requires railroad track spiral shell
There is nail rust-inhibiting lubricant temperature very wide to use scope, it is therefore necessary to which developing one kind had not only had rust-inhibiting lubricant characteristic but also tool
There is the railroad track screw antirust special grease of low temperature grease characteristic.
The content of the invention
Present invention solves the technical problem that a kind of railroad track screw rust-inhibiting lubricant and preparation method thereof is there is provided, should
The screw division position that lubricating grease is used for railroad track ensure that screw, for a long time not by corrosion, the safety of track traffic is ensured with this
Property, while this lubricating grease can be used throughout the country, it is to avoid the limitation that different geographical is used lubricating grease.
The present invention is to solve above-mentioned technical problem to adopt the following technical scheme that, railroad track screw rust-inhibiting lubricant, and it is special
Levy and be that what the raw material matched by following weight percent was prepared from：Base oil 70%-85%, thickening agent 10%-20%, additive
3%-4% and coal tar 2%-6%, wherein base oil be synthesize alkene oil or transformer oil in one or more, thickening agent is ten
The compound soap of dihydroxy aliphatic acid lithium salts and decanedioic acid lithium salts, additive is organic phosphate preservative, phenylenediamine compound resists
Oxidant and poly-alpha-olefin pour depressant.
Further preferably, ten described dihydroxy aliphatic acid lithium salts are lithium 12-hydroxy stearate salt, described preservative
It is fatty acid amide phosphate, described phenylenediamine compound is diphenylamines.
The preparation method of railroad track screw rust-inhibiting lubricant of the present invention, it is characterised in that concretely comprise the following steps：Will
The synthesis alkene oil of 56.2 weight portions is added in saponification kettle, is heated to 80 DEG C to adding 6.3 weight portions in saponification kettle
Ten dihydroxystearic acids, 90 DEG C are warming up to after ten dihydroxystearic acids are completely dissolved, and to being added in saponification kettle, lithium hydroxide is molten
Liquid, the lithium hydroxide solution is prepared from by the lithium hydroxide of 2.9 weight portions and the water of 8.7 weight portions, and continuing to heat up takes off
Water, the decanedioic acid of 4.8 weight portions is added when saponification temperature in the kettle rises to 130 DEG C and 30min is incubated, and end temperature rises to 180
DEG C stop heat up, circulation temperature lowering, shearing, added when saponification temperature in the kettle is down to 150 DEG C 18.8 weight portions synthesis alkene oil,
Add the coal tar of 6 weight portions, added when saponification temperature in the kettle is down to 100 DEG C 0.8 weight portion fatty acid amide phosphate,
The poly alpha olefin of the diphenylamines of 1.2 weight portions and 1 weight portion, shearing, degassing is obtained railroad track screw rust-inhibiting lubricant.
Obtained lubricating grease of the invention is railroad track screw antirust special grease, multiple using thickening agent aliphatic acid lithium salts
The base oil that soap thickening cryogenic property reaches -50 DEG C is closed, along with anticorrosive, antioxidant and pour-point depressant, it is ensured that lubricating grease
Scope is used with excellent rustless property and temperature wider, the adhesive force that adding coal tar can improve lubricating grease is dripped simultaneously
Blue or green oil has good air exclusion ability, and good antirust function can be played to screw.
Specific embodiment
The above of the invention is described in further details by the following examples, but this should not be interpreted as this
The scope for inventing above-mentioned theme is only limitted to following embodiment, and all technologies realized based on the above of the present invention belong to this hair
Bright scope.
Embodiment
56.2 kilograms of synthesis alkene oil are added in saponification kettle, 80 DEG C is heated to the public affairs of addition 6.3 in saponification kettle
