Abstract
Disclosed is a preparation method of electric contact lubricant, comprising lithium-based grease, vaseline and transmission fluid. The lubricant adapting to the electric contact working conditions is an effective electric contact protecting grease and also an electric contact grease lubricant having a long life and being capable of functioning properly as an antirust agent even at a high temperature in a vacuum environment.
Description
Technical field
The present invention relates to a kind of lubricant, be applied to a kind of anti corrosion lubricant of electric contact especially.
Background technology
The corrosive definition is exactly under certain environment, and metal is owing to the damage that chemical reaction (mainly being oxidizing reaction) suffers takes place.Corrosion mainly is a kind of electrochemical process.Be in contact with one another as different metals, perhaps have the oxygen or the electrolytic solution of different concns, will form a slight battery, metal is corroded.Corrosion occurs in anode.At the electric contact position, it mainly is because the discontinuity of electric current is passed through that corrosive takes place.
Pass through if electric current is continual, can not cause corrosion so.Yet for most of equipment, in case stop work, just do not had electric current, will corrode this moment.Corrosion of metal similarly is people's a disease, and metal is ruined more and more serious.Therefore must control and eliminate it.
Here have a lot of methods can stop the corrosion of electric contact position, a kind of method is exactly to add a kind of anticorrosion medium between the electric contact interface, yet current All Media also can corrode through after a while.Another method makes the electric contact position be in the vacuum exactly, but this is unpractical.A kind of method is exactly to protect metal at metallic surface plating one deck zinc, but zinc can decompose, and under certain conditions can be non-conductive suddenly.Another way is exactly to be coated with the very thin oil film of one deck in the metallic surface, and oil film also only provides temporary transient anticorrosion protection.Replace oil with lubricating grease, the protection phase of lubricating grease can reach the several months long.
Corrosion of metal can produce the insulation position, and will to reduce and finally stop passing through of electric current, current the most frequently used method fully be exactly that the isolator that produces is carried out physical removal in the existence of isolator so.General is exactly isolator to be removed as removing sand with hand.This just means wants the regular electric contact position is safeguarded.Under some environment, on the deck such as ship, owing to be under the high humidity environment for a long time, so the time that this maintenance will be expensive.On a big ship, such electric contact has several thousand, so this maintenance difficulties is very big.
In the past, itself is rotten after after a while for used electric contact point lubricating fat, and general is some months, and is best also with regard to 1 year 2 years.Before the present invention, there is not a kind of electric contact point lubricating fat can effectively protect the electric contact several years.
For automobile and truck, common way is changed part exactly.Unnecessary cost the hundreds of U.S. dollar changed after the part, just can a bit deep understanding be arranged to this problem, we should drop into more concern to electric welding system.
Summary of the invention
Main purpose of the present invention just provides a kind of electric contact point lubricating fat, and electric contact is normally moved, and can set up barrier between metallic surface and surrounding environment again, avoids metal to produce corrosion with temperature through moisture and goes bad.
Another purpose of the present invention prepares a kind of compound exactly, can protect the time in several years of electric contact works better effectively in the environment in gentle supermarket.When the gas of humidity immerses electric wire, this compound can make voltage normally by and without any obstruction.This compound that the present invention mentions itself also is very good electric conductor.
Another purpose of the present invention is exactly to prevent that effectively short circuit phenomenon from appearring in equipment.
The consisting of of anticorrosive lubricant among the present invention: the massfraction of Vaseline is 51.8.0-53.2%, and the massfraction of lithium soap grease is 47.0-48.0%, and the massfraction of transmission fluid is 0.002-1.2%.More than three kinds of compositions or compound uniform mixing.
The raw material of used lithium soap grease all is easy to obtain among the present invention, and market is on sale.
Vaseline among the present invention also is very common product, and all there are production and sales in a lot of producers.
The effect of the conductive liquid among the present invention is to make lubricant have electroconductibility, and prevents that in the time in several years lubricating grease from becoming dry.After several years, lubricating grease remains soft ointment.Also because so, this lubricant still has protective effect.Conductive liquid generally is petroleum-based, and market is on sale.
Described a kind of conductive liquid is characterized in that described base oil is a kind of in mineral oil and the synthetic oil or both mixtures, and its massfraction is between the 94.0-95.0%.
Described a kind of conductive liquid is characterized in that described viscosity index improver is a polymethacrylate, and its massfraction is between the 0.5-1.5%.
Described a kind of conductive liquid is characterized in that described sanitas is the sulphur phosphide, and its massfraction is between the 0.1-1.0%.
Described a kind of conductive liquid is characterized in that described oxidation inhibitor is poly-α-An Jinai, and its massfraction is between the 0.1-1.0%.
Described a kind of conductive liquid is characterized in that described sealing agent is a diethyl phthalate, and its massfraction is between the 1.0-3.0%.
Described a kind of conductive liquid is characterized in that described dispersion agent is the polyisobutene acid amides, and its massfraction is between the 0.8-2.0%.
Described a kind of conductive liquid, it is characterized in that described anti-wear agent be Methyl disulfide for zinc phosphate, its massfraction is between the 0.1-1.0%.
Described a kind of conductive liquid is characterized in that described kilfoam is a polydimethyl siloxane fluid, and its massfraction is between the 0.001-0.01%.
A kind of percent by volume of more satisfactory conductive liquid is: 94.918% base oil, as mineral oil; 1.0% viscosity index improver is as polymethacrylate; 0.3% sanitas is as the sulphur phosphide; 0.3% oxidation inhibitor is as poly-α-An Jinai; 0.4% friction improver; 2.0% sealing agent is as diethyl phthalate; 1.5% dispersion agent is as the polyisobutene acid amides; 0.3% wear preventive additive, as Methyl disulfide for zinc phosphate; 0.002% foam reducing composition is as polydimethyl siloxane fluid etc.More than be industrial goods, market is on sale.
The effect of viscosity index improver is exactly to improve in order to allow the thinning situation of oil product high temperature.The effect of oxidation inhibitor is to prevent that oil product from chemical reaction taking place in the environment of oxygen is arranged go bad.Wear preventive additive mainly be in and electric contact may touch have corrosive sour gas.Dispersion agent is in order to stop particulate to produce, such as the carbon granules of lubricant limit face.Add sanitas clearly be exactly in order to prevent the corrosion of electric contact.Friction improver is very important also, because it can help lubricant to stick on the electric contact, the blocking-up surrounding gas directly contacts with electric contact.The effect of kilfoam is to stop oil product to suck air between the usage period of oil product to produce foam.
