Abstract
The invention discloses industrial gear oil, which contains the following components by weight percent: 98-99.5 percent of base oil with saturated hydrocarbon content being more than 90 percent and sulfur content being less than 0.03 percent, 0.1-0.5 percent of amine antioxidant, 0.1-0.9 percent of sulfur-containing extreme pressure antiwear agent, 0.02-0.1 percent of antirust and anticorrosion additive, 0.01-0.05 percent of metal deactivator and 0.001-0.5 percent of anti-foaming agent. The industrial gear oil provided by the invention has good extreme pressure lubricating performance and good antirust and anticorrosion performance, and has the advantages of high quality, long service life, no pollution and the like; by formulating the high-quality base oil and novel environmental-friendly gear oil additives and by using the unique extreme pressure antiwear agent, not only can the bearing capacity of the gear oil be greatly improved, but also the impact caused by the traditional lead-containing formula to the health of operating workers is precluded and the surfaces of steel and copper parts can be effectively prevented from being worn; and due to proper adhesiveness and extremely low friction coefficient, the noise produced by gears during operation and the temperature of a machine body can be effectively reduced, the energy consumption is reduced and the service life of the gears is prolonged.
Description
Technical field
The invention belongs to technical field of lubricating oil, relate to a kind of industrial gear oil.
Background technology
Current, it is not enough that commercially available gear oil product ubiquity the extreme boundary lubrication performance, antirust resistance to corrosion is inadequate, and the problem that occurs the aspects such as irritating smell in the course of processing, may cause greatly shorten cutter life, the deterioration of course of processing workpiece corrosion, workpiece surface quality reduction and processing environment, greatly reduced process for processing efficiency and cost.
Summary of the invention
The technical problem to be solved in the present invention is: provide the industrial gear oil that a kind of extreme boundary lubrication performance is good, anti-rust and anti-corrosion is good, to overcome the deficiencies in the prior art.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of industrial gear oil, is characterized in that, following components by weight percent, consists of:
In above-mentioned formula:
Amine antioxidants is one or several the mixture in the ethyl of the butyl of the butyl that mixes/ethyl alkylated diphenylamine, mixing/alkylated styrene pentanoic, mixing/vinyl toluene base alkylated diphenylamine and octyl group alkylation phenyl-alpha-naphthylamine.
The sulfur-bearing extreme-pressure anti-friction additive is one or several the mixture in olefine sulfide, sulfide aliphatic acid, ash-free dithiocarbamates and sulfurized olefin cotton oil.
The rust resistance and corrosion resistance additive is a kind of in phosphate amine salt, alkenyl succinic acid, alkenyl succinic acid ester, neutral naphthalene sulfonate barium, alkaline dinonyl naphthalene sulfonate barium and barium mahogany sulfonate.
Metal passivator is methyl benzotriazole derivative or thiadiazoles derivative.
Kilfoam is methyl-monosilane mixture or liquid ester multipolymer.
Preparation method and the step of above-mentioned industrial gear oil are as follows:
Base oil is heated to 50-80 ℃, adds successively amine antioxidants, sulfur-bearing extreme pressure anti-wear additives, antirust rut preventives, metal passivator, defoamer, be uniformly mixed 1-5 hour,, through overcooling, essence filter, obtain product.
The invention has the beneficial effects as follows:
That industrial gear oil of the present invention has is of fine quality, the life-span long, the advantage such as pollution-free, be applicable to the bearing of large, medium and small type steamer (water wheels) unit and lubricating of circulation regulation system, be mainly used in 300MW above steam turbine or gas turbine, also can be used as precision optical machinery, hydraulic efficiency system, heat-transfer system and turbine bearing and drag reduction bearing, closed type tooth roller box etc. and do not need the preferred emollient of tool antiwear and extreme pressure properties system.
Industrial gear oil of the present invention employing high-quality base oil and novel environment friendly gear oil additive are composite.Unique extreme pressure anti-wear additives, not only significantly improve the supporting capacity of gear oil, more stopped the impact of the health that traditional leaded formula causes the operator, and can effectively prevent the wearing and tearing of steel and copper piece surface; Appropriate adhesivity and extremely low frictional coefficient, can effectively reduce noise and organism temperature that gear produces in the running, reduces energy consumption, extends gear life.In the situation that properties all excellent, guarantee the normal operation of steam turbine, can greatly extend the work-ing life of oil product, reduce the frequency of changing oil, save enterprise cost, promote profit margin.
