Description
Technical field
The invention discloses the preparation method of a kind of high temperature resistant organobentonite Machinery grease, belong to grease synthesis neck
Territory.
Background technology
Bentonite grease is the non-soap base Hmp grease that a class is important, is with modified alta-mud thickening mineral oil or conjunction
Become high temperature lubricating fat prod prepared by lubricating oil.With polyureas base grease, complex lithium grease, complex calcium sulfonate grease
Equally, bentonite grease is also a kind of common Hmp grease kind, and it produces and the exploitation of new product receives many states
The attention of family.Adding up according to National Lubricating Grease association, within 2010, world's bentonite grease yield accounts for whole world grease total output
1.77%, and China's bentonite grease accounts for the 0.77% of grease total output, compares the accounting 0.34% of 2009, and China is swollen
The yield of profit soil grease increases, but compared with world average level, the bentonite grease of China produces the biggest
Growth space.
Bentonite grease thermostability is high, has good mechanical stability and colloid stability, be generally used for high temperature,
Heavy load, slow-revving mechanical lubrication.When base oil condensation point is relatively low, the special lubricant housings under common-use words aviation and low temperature,
It it is a kind of rising high temperature inorganic grease.Bentonite is the mineral with montmorillonite as main component or montmorillonite reaches
The clay pit of available content.Bentonitic industrial value is from montmorillonite, and why bentonite can be as grease thickening
Agent, the montmorillonite being because modification passes through mechanical shearing and dispersion aids effect, and montmorillonite wafer can be effectively dispersed in basis
Oil is formed network structure colloid, i.e. obtains bentonite grease.Existing bentonite grease product there is also some shortcomings,
As: organic modifiers heat decomposition temperature is the highest, meets the easy emulsifying of water etc..And in production process, higher to raw-material requirement, price
Costliness, causes production cost higher, and these factors all constrain application and the development of bentonite grease.
Summary of the invention
The technical problem that present invention mainly solves, occurs during preparation and use for tradition bentonite grease
, under the high-temperature work environment more than 150 DEG C, its internal organic modifiers easily decomposes, and meets the easy emulsifying of water, thus affects
The problem in the service life of grease, it is provided that the preparation method of a kind of high temperature resistant organobentonite Machinery grease, the present invention
Initially with oil raw material based on Oleum Ricini, the product modification under glacial acetic acid and hydrogen peroxide are at sulphuric acid catalysis, lubricated
Fat base oil, then bentonite is mixed with carbamide and coal mine sewage, after inoculation Lumbricus, progressively add low concentration formaldehyde, through earthworm
The digestive system of earthworm and internal microbial action thereof, the abundant microorganism in mixed coal Mine waste water, modified alta-mud, through micro-
After Wave heating processes, it is mixed to get high temperature resistant organobentonite mechanical lubrication with base oil and polarity dispersant ethanol heated and stirred
Fat.In use, mechanical gear position operating temperature reaches more than 280 DEG C to gained grease, still can steady operation, do not occur
Degrade, and chance water does not occur emulsion, can promote the use of.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
(1) measuring 80～120mL glacial acetic acid successively, 60～80mL mass concentrations are 20～25% hydrogen peroxide, and 20～30mL mass are dense
Degree is 98% concentrated sulphuric acid, adds in Dropping funnel after mixing, then is installed on by Dropping funnel and fills three mouthfuls of 20～30mL Oleum Ricini
On flask, subsequently there-necked flask is placed in digital display and tests the speed in constant temperature blender with magnetic force, be heated to 55～65 DEG C, start stirring
Device, setting speed to 520～560r/min, under constant temperature stirring condition, in controlling Dropping funnel, mixed solution is 45～60min
Interior dropping is complete, continues reaction 3～5h；
(2) question response terminates, and in there-necked flask, material proceeds to separatory funnel, dropping mass concentration is 0.6～0.8% hydrogen-oxygen
Changing sodium solution, regulate pH to 5.0～5.2, stand, layering removes aqueous phase, obtains base oil, standby；
(3), after weighing bentonite 2～3kg, 160～180g carbamide and 2～3L coal mine sewage mix homogeneously successively, it is stacked at and keeps away
Light ventilation, by 25～30% inoculum concentration inoculation Lumbricus, covers one layer 3～5cm thickness Caulis et Folium Oryzae subsequently on bentonite surface, every 4～
6h is 2～4% formalin to Caulis et Folium Oryzae surface sprinkling 30～50mL mass concentration, carries out vermiculture 6～8 days；
(4) treat that cultivation terminates, be separated off Lumbricus and surface mulching straw, bentonite proceeded in microwave reactor, with 460～
520W power, reacting by heating 20～30min, discharging, stand so that it is naturally cool to room temperature, obtain organic modified bentonite；
(5) count by weight, weigh 20～30 parts of standby base oils of step (2), add in fat still processed, turn on agitator, if
Determine rotating speed to 360～420r/min, be heated to 55～60 DEG C, under constant temperature stirring condition, add 40～45 parts above-mentioned
Gained organic modified bentonite, 10～15 parts of dehydrated alcohol, continue constant temperature stirring mixing 40～60min, discharging, obtain high temperature resistant
Organobentonite Machinery grease.
The concrete application process of the present invention: take 120～180g gained of the present invention high temperature resistant organobentonite Machinery grease,
Being evenly applied to hyperthermia tunnel Kiln skiving wheel surface, coating thickness is 3～5mm, under 200～220 DEG C of hot conditionss use 3～
After 5 months, after testing, evaporation loss is less, is 6～8%, its adhesion (water resistant is sprayed, 38 DEG C, 5min) reach 1.06～
1.08%, after 100,000 mechanical shearing effects, cone penetration does not changes, and illustrates that its thixotropy is good, and good mechanical stability makes
With lasting a long time.
The invention has the beneficial effects as follows:
(1) gained grease of the present invention disclosure satisfy that the industrial application environment of high temperature, low temperature, high shear, high load capacity, uses temperature
