Description
[technical field]
The invention belongs to technical field of lubricating oil, relate to a kind of spirit thinned type open gear lubricatng and preparation method thereof, in particular for the lubricating oil of colliery, the large-scale exposed gear of cement industry equipment.
[background technology]
Spirit thinned type exposed gear oil is the semifluid lubricant on a kind of main equipment (such as ball mill, tuber grinder, rod mill, rotary kiln, drying machine, tablets press, drum type pulp kneader) that is widely used in the industries such as electric power, mine, cement, iron and steel, chemical industry, papermaking.Early production adopts the volatile solvents such as trieline, zellon as diluting solvent more, and these chlorinated solvents have very large toxicity, can have a strong impact on operator's physical and mental health in research and development, production and use procedure.Especially the exposed gear oil that contains trieline is the characteristics of utilizing its volatilization fast, evaporate into the destruction that also can cause in the ambient atmosphere ozonosphere.
These unfavorable factors have all affected the widespread use of spirit thinned type exposed gear oil, especially for environmental requirement comparatively harsh North America, European countries.Arrive the mid-80 as far back as late 1970s, the user of North America, Europe, Australia and Asia Countries is when selecting lubricant, consider that at first lubricant does not exist environment, safety, health risk, and then consider that lubricant satisfies the requirement of the commercial fuel oil meter lattice of device fabrication.Most of oil companies are also because the consideration of environment protection and health factor has been carried out corresponding variation to oil product.These causes of changes are the awakening of the continuous environment of strengthening, safety, health perception.Overwhelming majority's lubricant manufacturers has developed the exposed gear lubricating agent that makes new advances, and substitutes the solvent pitch type lubricant that has used for many years.China still belongs to blank in the research of the development field of environment-friendly type spirit thinned type exposed gear oil.
[summary of the invention]
The purpose of this invention is to provide a kind of avirulent spirit thinned type open gear lubricatng, be applied to the lubricated of colliery, the large-scale exposed gear of cement industry equipment.
Another object of the present invention provides the preparation method of this spirit thinned type open gear lubricatng.
To achieve these goals, the technical solution used in the present invention: this spirit thinned type open gear lubricatng is characterized in that by following materials in percentage by mass preparation: 20-70% pitch, 10-30% mineral oil, 10-50% normal alkane solvent, 1-10% adhesive agent, 0.5-8% extreme-pressure additive, 0.1-5% anti-wear agent, 0.01-1% dispersion agent, 0.001-0.01% metal passivator.
Described pitch adopts molten-gel type bitumens.
Described mineral oil is MVI or HVI mineral oil, or their composition.
Described normal alkane solvent is that carbon number distribution is at the mixture of the normal paraffin of C9～C14.
The macromole polymerization esterification product that described adhesive agent is formed through cross-linked esterification by poly-basic organic acid, polyvalent alcohol.
Described extreme-pressure additive is olefine sulfide or extreme-pressure additive T321.
Described anti-wear agent is phosphorous acid ester, phosphoric acid ester or phosphate derivative, or their mixture or di-n-butyl phosphite or tritolyl phosphate or thiosulfates.
Described dispersion agent is succimide or derivatives thereof or two succimide or many succimides.
Described metal passivator is 124 Triazole derivative or thiadiazoles derivative.
The preparation method of this spirit thinned type open gear lubricatng, in the steps below preparation: 1, extreme-pressure additive, anti-wear agent, dispersion agent and metal passivator component ratio are mixed into recombiner; 2, with molten-gel type bitumens heating and melting to liquid, and fully mix with mineral oil; 3, the mixture that the recombiner that under 50-60 ℃ normal alkane solvent, adhesive agent, the 1st step is closed and the 2nd step obtain fully stirs fusion, finally obtains the spirit thinned type open gear lubricatng.
Take pitch as main body, add extreme-pressure additive and diluting solvent among the present invention, have extraordinary oil film and form ability and resistance to elevated temperatures, and have price advantage.Pitch adopts molten-gel type bitumens to take into account flowability, adhering product, compares with plain asphalt, has certain fluidity, and better solvability is arranged in organic solvent; The mineral oil that the base oil selected depth is refining, or the mixture of multi mineral oil; Solvent is selected high volatile volatile, avirulent refining of petroleum product, or their mixture; To binder component, consider that exposed gear equipment is exposed under the physical environment, the operating mode of low-speed heave-load, select the adhesive agent that has the good adhesion ability and do not affect the product low-temperature performance; Simultaneously because the foreign matter content of pitch is more, therefore with the extreme pressure and antiwear behavior of binder component and dispersing property, the antiseptic property foundation as preferential selection.Because this two aspects performance often is conflicting in additive combination, not only screen for these two kinds of binder components, consider simultaneously the balance of binder component ratio.The present invention is chlorinated solvents not, and nontoxicity can not affect operator's physical and mental health in research and development, production and use procedure, on not impact of environment.
Estimate the performance of lubricating oil of the present invention below in conjunction with specific embodiment, adopt four ball extreme pressure test (GB/T3142 method) to evaluate its extreme pressure property, adopt copper corrosion (GB/T5096) to evaluate its antiseptic property, adopt pour point (GB/T3535) to evaluate its low-temperature performance.
