Description
The present invention relates to a kind of oilness of promoting lubricant and the additive of anti-attrition, be specially adapted to diesel engine, the solid-liquid composite lubricating oil wear reducing additive on the lubricating system of IC engine such as petrol motor.
In daily use, usually the way for the friction and wear of the part of reducing friction is lubricated.Generally be two friction surfaces to be separated to reduce friction and to wear and tear with lubricating oil or solid lubricant.But their limitation is arranged, as use lubricating oil, generally when the surface of friction contact pressure is low or when reaching the ideal Liquid Lubrication Condition, use fair.But start, when stopping and sliding velocity reduce to zero or low cruise when forming boundary lubrication condition, the corresponding increase of frictional force also produces wearing and tearing; Simultaneously a large amount of heat of friction produce, and make it frictional surface temperature and raise.Thus, general lubricating oil also is not a kind of ideal lubricant.Using solid lubricant, handle at coating for metal surfaces, all is the excellent lubrication agent as tetrafluoroethylene, graphite, molybdenumdisulphide etc., when low cruise, is better than lubricating oil.But tend to be accompanied by the wearing and tearing of contact component, and price is expensive.
The up-to-date patented product of a series of wear reducing additives appears on the world market in recent years: U.S. TMT(Total Moter Treatment), Japanese NASA101(NASA SOPER OIL TREATMET), U.S. TP(TRI-PAK company) etc. a series of wear reducing additives, become the eighties product innovation.United States Patent (USP) U.S.Patent № 4349444(82), 3933656(79) " openly specially permit the clear 53-34808 of communique " etc. relevant technology has been made report with Japanese Patent.But United States Patent (USP) has only been introduced main raw material (tetrafluoroethylene) and main stablizer (silane, fluorochemical surfactant and silane derivative), prescription as for it is formed, component title and adding proportion, processing condition, implementation result etc., there is no disclosure.And Japanese Patent does not appear in the newspapers to technical recipe.Early eighties, domestic some unit begins import and wear preventive additives such as TMT on probation, TP.After showing these wear preventive additives of interpolation after on probation, can reduce the wearing and tearing of oil engine machinery, reduce oil consumption, prolong the oil exchange time limit and reduce machine overhaul number of times.But there are two big defectives in this class additive.The first costs an arm and a leg.Every jar of 8 ounces of (OZS)=236.6ml dress, price TMT～TP=19～42 yuan (amounting to Renminbi); It two is that the TMT of the U.S. adopts silane and derivative and fluorochemical surfactant thereof as stablizer, they belong to inflammable articles, and contain the benzene analog derivative among the TP is dangerous product, they these not only use, all unfavorable ， And is poisonous and hazardous to aspects such as HUMAN HEALTH, environmental healths in transportation.
The objective of the invention is to improve the defective that domestic and international liquid lubricant, solid lubricant and metal antiwear agent exist, learn from other's strong points to offset one's weaknesses, provide a kind of energy-saving friction-reducing, solid-liquid lubricating oil wear reducing additive cheap and easy to get, nontoxic.
The present invention realizes with following method: with lubricating oil or the suitable neutral base oil of viscosity is carrier, and it is formulated to add polytetrafluoroethyldispersion dispersion and compositions such as polyoxyethylene glycol, polyol-based non-ionic surfactant and polymethacrylate viscosity index improver.Concrete compound method is as follows:
1. get 4～8 parts of (weight ratio, together following) polytetrafluoroethyldispersion dispersions (concentration 15%), add 1～2 portion of polyoxyethylene glycol nonionogenic tenside, after shaking up, this liquid is joined mixing and stirring in the suitable neutral base oil of lubricating oil that 20～25 parts of viscosity are 10～16 centistokes/100 ℃ or viscosity, be milk sap.
2. get 40～45 parts, viscosity lubricating oil same as described above adds 2～3 portions of oil soluble polyvalent alcohol nonionogenic tensides and 0.5～1 portion of water-soluble polyol nonionogenic tenside and 0.5～1 part of polymethacrylate type viscosity index improver, heating makes it to dissolve fully, be cooled to room temperature again, be synthetic neutral base oil.
3. the above-mentioned neutral base oil that modulates is admixed lentamente to mix in the milk sap and mixed thoroughly, be solid-liquid composite lubricating oil wear reducing additive of the present invention.
Said tetrafluoroethylene solid lubricant, it is a kind of milky Colloidal fluid, contain 60% particle diameter and be 0.1～0.8 micron tetrafluoroethylene particulate, this colloidal dispersion, generally electronegative, extremely unstable, electric charge is not to be evenly distributed between particle surface and particle, will condense when two utmost point particles attract each other, so must add stablizer, tensio-active agent, viscosity index improver etc.Make of the circulation of the particulate of tetrafluoroethylene with lubricating oil; it can soak in the uneven space of many depressions on the metal friction surface of cylinder wall, piston, piston ring and bearing; fill up and be coated with and act on; form one deck level and smooth, firm, stablize protective membrane; make can not be in contact with one another between metal and the metal and seam or the mutual embedding of micro-bulge take place, the solid lubricant overcoat is in operation to get back and brings in constant renewal in and replenish.
Said polyethylene glycol type nonionogenic tenside is a kind of Colloidal fluid that easily flows, and it can reduce the surface tension of tetrafluoroethylene colloidal dispersion, and the particulate of tetrafluoroethylene is not condensed, and makes it stable, obtains a kind of milk sap.
Said oil soluble and water miscible polyol-based non-ionic surfactant are a kind of thickness Colloidal fluids, and the color of water-soluble polyol type is more shallow, and more more viscous; they can reduce the interfacial tension of water-oil interface; increase the protection film strength, reach the hydrophilic-hydrophobic balance, promote emulsification.
Said polymethacrylate type viscosity index improver is a kind of near the water white transparency Colloidal fluid, and it can not only increase the displacement that interfacial film viscosity hinders emulsification molecule on the interface, is difficult for cohesion; And can improve its viscosity index, enlarge the use temperature scope of lubricating oil; And tend towards stability certain effect is also arranged promoting colloidal solution.
The neutral base oil that said lubricating oil or viscosity are suitable is that a kind of viscosity is 10～16 centistokes/100 ℃ plain oils.It is a preparation additive carrier of the present invention (being mother liquor).
Advantage of the present invention:
(1) owing to form the stable solid protective membrane of one deck at the friction surface of metal, machinery, to promote lubricatedly, the power loss of reducing friction prolongs oil engine work-ing life, reduces oil exchange time limit and machine overhaul number of times, and And reduces barrel wear 82%;
(2) because burning fully, reduces oil consumption, rate of economizing gasoline reaches 2～5%;
(3) because the cylinder seal performance improves, and cylinder pressure increases, and it is perfect to burn, and carbon monoxide, hydrocarbon content descend in the exhaust gas emission thereupon, reduce topsoil;
(4) to select additive raw material for use be cheap and easy to get in the present invention, nontoxic.
In a word, additive of the present invention has remedied the weak point of common lubricant, the solid lubricant that is better than again handling at coating for metal surfaces is the comprehensive lubricant of a kind of solid-liquid, and it especially is useful in internal combustion engine start, stop or during low cruise, even in the machine oil supply failure in emergency circumstances.
