Abstract
The invention discloses a solvent-diluted open-typed gear lubricant, which is characterized by the following: the basic oil is high-viscosity synthesized oil; the thickener is composite calcium sulfonate; the additive is auxiliary extreme-pressure agent, anti-oxidant and diluent; the lucribant possesses superior high-low temperature adaptability (low-temperature fluidity and high-temperature adhesive), which is not easy to volatilize under normal temperature.
Description
Technical field
The present invention relates to a kind of lubricating grease, exactly is a kind of open-type gear grease of spirit thinned type.
Background technology
The open gearing of cement, mining and smelter is more, as the exposed gear at the lifting of the import power shovel of the rotary kiln exposed gear in cement mill extreme condition, sleet such as (wash away) high low temperature, mining station-service, pushing, revolution position (day and night temperature is big, sleet, dust, impact load), the exposed gear of the large-size ball mill in dressing-works (linear velocity height, easily get rid of oil), the exposed gear of mixer and carrying roller etc.Its work characteristics is that dust impurity is many, impact load, circumstance of temperature difference is big, sleet washes away etc.Its lubricating system is many to spray or pumping realizes.To the requirement of lubricating oil be viscosity good, do not get rid of oil, high-low temperature resistant, extreme pressure anti-wear height, rust-preventing characteristic is good, water resisting property is strong.
The tradition exposed gear is that the viscosity that adds extreme pressure agent oxidation inhibitor is the lubricating oil of No. 680 or No. 1000, but that its shortcoming is a viscosity is not enough, often gets rid of oil, pollutes; Oil film is thin, and regular meeting causes rippling.Also have exposed gear oil, add mineral oil and extreme pressure agent, but its low-temperature fluidity is poor, is difficult for pumping based on asphaltic base, and low-temperature embrittleness, it is its main drawback that high temperature easily runs off.Follow-on asphaltic base lubricating oil is added to dilute into solvent, has improved low-temperature performance, can stop up with the volatilization of solvent but shortcoming is the nozzle that refuels, and causes the trouble in the maintenance; Low-temperature performance is affected again when avoiding stifled nozzle to reduce solvent load.Adding in recent years also makes the application of pitch type product be restricted to environmental protection requirement.External and domestic also useful in recent years No. 0 or No. 00 lubricating grease lubricate, but viscosity is not enough, easily gets rid of oil, often spray, and cause waste and pollute.Innovative product can add tackifier usually, but poor performance at low temperatures, pumping or jeting effect are not good.
Summary of the invention
The purpose of this invention is to provide a kind of fine spirit thinned type open-type gear grease, this lubricating grease has good viscosity, good high low temperature adaptability (low-temperature fluidity, high temperature adhesion) and excellent antirust water repelling property.
The thinner that adds will have following performance: good product mobility during low temperature (being easy to pumping or injection), not volatile during normal temperature (not stifled nozzle), high-temperature volatile good (remaining lubricating grease has high-temperature behavior).So choice of Solvent is important, has chosen the high temperature low-temperature performance is taken into account.Base oil of the present invention is the high viscosity synthetic oil, and viscosifying agent is a complex calcium sulfonate, and additive is auxiliary extreme pressure agent, oxidation inhibitor, and thinner is a high-flash solvent oil.The present invention has satisfied the service requirements of equipment fully, because the existence of solvent oil makes the temperature pumping excellence, the normal temperature volatilization is few, and nozzle does not stop up; Because basic oil viscosity height, the viscosity of finished product is good, does not get rid of oil; Since the existence of viscosifying agent, solvent oil volatilization under the high temperature, and remainder is the lubricating grease of high viscosity.The present invention is wideer than asphaltic base product and semi-fluid (No. 0, No. 00) grease product to the adaptability of temperature, can adapt to the needs of cryogenic spray and pumping, also adapts to high temperature service, and is lubricated as the exposed gear of rotary cement kiln.
Open-type gear grease is characterized in that it is made of by weight ratio following compositions:
Synthetic base oil: 30-74
High base number calcium mahogany sulfonate: 10-34
Auxiliary extreme pressure agent: 5-8
Oxidation inhibitor: 1-3
Solvent oil: 10-30
Described synthetic base oil is meant one or more the mixture in high viscosity ester class oil, high viscosity polybutene, high viscosity synthetic hydrocarbon oil, the polymethacrylate, makes product have excellent viscosity.Ester class oil comprises trimellitate, multiple ester etc.; Polybutene comprises that viscosity grade is the product (relative molecular mass is 620-5900) of 3-2000; The high viscosity synthetic hydrocarbon oil comprises PAO40, PAO100 or the arbitrary viscosity grade product between the two.
Described synthetic base oil is meant one or more the mixture in high viscosity ester class oil, high viscosity polybutene, high viscosity synthetic hydrocarbon oil, the polymethacrylate; Ester class oil comprises trimellitate, multiple ester etc.; Polybutene comprises that viscosity grade (100 Saybolt viscositys are divided by the big round number after 100) is the product of 3-2000, and relative molecular mass is 620-5900; The high viscosity synthetic hydrocarbon oil comprises PAO40, PAO100 or the arbitrary viscosity grade product between the two.
Described high base number calcium mahogany sulfonate, base number is 300-400mgKOH/g, adds suitable quantity of water, transforms 30-90 minute at 90-100 ℃, is warmed up to 130 ℃ and sloughs moisture, promptly gets the complex calcium sulfonate viscosifying agent.It has very high extreme pressure property, the dropping point height.
Described auxiliary extreme pressure agent is meant one or more the mixture in the materials such as graphite, molybdenumdisulphide, organic sulfide, Organophosphorous compounds, organic chloride, borate, Mobil additive G361, ethyl additive HiTEC-343.
Described oxidation inhibitor is meant one or more mixtures in amine antioxidants or the phenolic antioxidant.
Described solvent oil is meant that 98% distillates the petroleum fractions into 220-350 ℃, as D60, D110 etc.
The production technique of open-type gear grease is: weight part in accordance with regulations adds whole synthetic oils basis oil, high base number calcium mahogany sulfonate, add suitable quantity of water, transform 30-90 minute at 50-100 ℃, be warmed up to 130 ℃ and slough moisture, promptly get the complex calcium sulfonate viscosifying agent, cool to below 60 ℃, add auxiliary extreme pressure agent, oxidation inhibitor and solvent oil, mix, filter, packing.
Open-type gear grease of the present invention has following advantage;
1) low-temperature fluidity is good, can satisfy pumping or splash lubrication mode under the low temperature;
2) because the high normal temperature of solvent boiling range is not volatile, not stifled nozzle;
3) viscosity good, do not get rid of oil, because the high viscosity synthetic base oil that adopts just is equivalent to tackifier;
