Technical field

The sequence number that the application requires to submit on April 26th, 2005 is 60675126, and exercise question is the right of priority of the provisional application of " with the high-temperature biological lubricant compositions of boron nitride preparation ".The present invention relates to by natural and/or synthetic vegetables oil, animal oil, vegetables oil or the tree oil biological lubricants composition with the boron nitride preparation.This composition is up to 1000 ℃ with oilness, resistance to abrasion and the extreme pressure property of improvement can be provided under the higher temperature.This composition is specially adapted to lubricated oil engine, baking box, chain, hawser, gear, joint pin, bearing and sliding surface under the hot environment.This lubricant compositions can also be blended into hydraulic efficiency oil, turbine oil, compressor oil, penetrating oil, lubricating grease, release agent, thread compound, metal deep drawing lubricating oil, rolling oil, metal working fluid, releasing agent, and any lubricant that needs resistance to abrasion and extreme pressure property.In addition, this lubricant compositions provides high insulation resistance, and this can be used for dielectric and insulating paste.

Background of invention

A large amount of bio-oils be can obtain from the recyclable resource of plant-derived oil, animal oil, vegetables oil or tree oil, readily biodegradable or " environment-protecting asepsis " it is characterized in that.Therefore, this oil has potential magnetism in various widespread uses, and is defined as biomaterial in 2002 in the farm bill.This type of bio-oil can be natural, also can be synthetic.

For being used for lubricating oil, bio-oil is also enough not desirable.Many bio-oils do not have desirable performance, comprise pour point, oxidative stability, with the consistency of additive etc.Yet bio-oil also has many ideal performances as lubricating oil.Particularly, bio-oil provides high flash point, good lubricity and very high viscosity index usually, and this can reduce oil consumption, and its volatility in the NOACK test is not more than 1%, and this shows that it can reduce the volatilization of machine oil.In addition, bio-oil is normally nontoxic, and readily biodegradable.For example, under standard test condition (such as OCED301D and ASTM D-5864 testing method), typical vegetables oil can biological degradation 80% in 28 days, is biodegradable to be carbonic acid gas and water, and under the contrast, oil-based lubricant is biodegradable to only have 25% or lower.When lubricant directly was discharged in the environment, this composition had special benefits.The sensitizing range comprises hanger rope and chain, dragline in forest zone, mining area, sea, farmland, heavy industry, transportation, railway and shipping, paper mill, sawmill, plywood factory, the sea-freight zone, strides and carry wood cargo vessel upper driving device, motorcycle and ATV chain etc.

Biomaterial in the composition and boron nitride are classified as the food grade license by USDA and NSF, are environment-protecting asepsis.The equipment that uses in the food-processing industry is different and different according to department, and three main departments comprise: meat and poultry, beverage, fast food, vegetables plant and milk-product.Although device is had any different between department, moving parts is identical such as bearing, gear, slipping plane, usually all needs to lubricate.The maximum lubricant that uses in these situations comprises baking box lubricant, chain lubricant, cable lubricant, permeability lubricating agent, release agent, thread compound, metal deep drawing lubricating oil, rolling oil, releasing agent, bearing oil, and the lubricating grease of various uses.These foodstuffs industry oil must satisfy stricter standard than other technical oils.

Owing to guarantee and to keep safety and the standard of food quite important, rule and the regulations of USDA (USDA) announcement must be observed by food factory.The food safety inspector-general's department (FSIS) of USDA is responsible for all programs of supervision, grading and the standard of meat, poultry, egg, milk-product, fruit and vegetables plant.These programs are enforceable, and the non-edible compound that is used for the device of federal government's check will detect.

FSIS is the depositary for the mandate compound official inventory of the device of federal government's check.Official's inventory (is seen the 11-1 page or leaf, " dedicated substances and the non-food product compound inventory " that USDA food safety supervision heat is promulgated, collected edition 1419 (1989)) indicating lubricant and other material of being designated as food is considered to indirect foodstuff additive in the USDA rules.Therefore, no matter these lubricants divide H-1 or H-2 into, all will obtain the approval of USDA before being used to food processing plant.The strictest criteria for classification H-1 is for the lubricant of contact food once in a while.The H-2 class is for the place that is used for impossible contact food, and guarantees not use in the lubricant known toxic substance or carcinogenic substance.The invention belongs to the lubricating oil of H-1 and H-2 approval.Lubricating oil and term " food grade " that H-1 and H-2 authorize will be at the application's Alternates.

Although USDA no longer ratifies new component and composition, global grocery trade is still approved H-1 and H-2 classification.Now NSF layout and approval food grade classification.

Except meeting the safety requirements of federal regulations office regulation, product must be effective lubricant.The lubricating oil of food processing apparatus should the lubricating machinery parts, and anti-stick degree changes, and is anti-oxidant, avoids getting rusty and corrode, and abrasion protection is provided, and in use will resist formation settling and greasy filth.Product also should can be brought into play useful effect under the various lubricating status in from the hydrodynamic thick film to border film scope.

The thermal characteristics of oxidation and lubricating oil can keep the time of lubricity and resist greasy filth and the effect of settling formation by aid forecasting lubricating oil.Can be partially oxidized when hydrocarbon ils and oxygen high temperature Long Term Contact, form hard settling, this can cause adhesion near tolerance metal and metallic contact zone.

Although this lubricant is nontoxic as food source impurity design, its lubricity and traditional lubrication oily (as, do not contain the lubricating oil that mandate can directly contact with food component) to compare effect poor.To a certain extent, lube plant solves these problems by introducing special additive to lubricant compositions.As, introduce that performance additive is wear-resistant to strengthen, oxidation suppresses, rust/erosion inhibition, metal passivation, extreme pressure, friction improve, anti-bubble and the performance such as lubricated.These reagent have description in following patent: U.S. Patent No. 5,538,6545 (Lawate etc.), U.S. Patent No. 4,062,785 (Nibert), U.S. Patent No. 4,828,727 (McAninch), U.S. Patent No. 5,338,471 and 5,413,7254 (Lai).

Document does not openly make lubricant formula contain vegetables oil and full hydrogenated oil (III class), does not have explanation and suggestion about the advantage of this prescription yet.Because full hydrogenation III class oil is made, there is not the solvent treatment step, when mentioning purification, it is better than II class and the III class base oil of production in keeping solvent-refined " mixing " device.In fact, in present available mineral oil, it contains minimum impurity, and this also makes it have obvious performance advantage.

Full hydrogenation technique comprises following three steps: hydrocracking, hydroisomerizing, hydrofinishing.In the first step hydrocracking, most of sulphur, nitrogen and basically whole non-hydrocarbon impurities be removed, most of aromatic hydrocarbons by hydrogenation by saturated.The Molecular remodeling of all the other saturate occurs, and opens such as ring, and paraffinic hydrocarbons isomery isomers redistribution etc. are to drive by thermodynamics, and speed of response promotes by catalyzer.The byproduct of next step of this step and this technique is clean fuel.In the second step hydroisomerization, normal paraffin and other have the molecule of ceraceous side chain to be isomerizated into branched chain molecule, simultaneously the pour point decrease.The aromatic hydrocarbons of most of surplus is by saturated, and sulphur and the nitrogen of most of surplus have been removed.In the end in the step hydrofinishing, any remaining non-isomerization alkanes impurity (sulfur-bearing thing, nitrogenous thing, aromatic hydrocarbons and alkene) all is removed to the trace level.

Know that full hydrogenation synthetics belongs to former III class base oil, but because synthesis technique, it can be modified and make up (chemically and physically) to III class scope.
