Description
Technical field
The invention belongs to technical field of lubricating grease, in particular to it is a kind of have high biological degradability and good anti-attrition,
The engineering machinery lubricating grease and preparation method of antioxidant, resistant of high or low temperature and adhesion.
Background technique
Engineering machinery includes all kinds of excavators, loading machine, bull-dozer, rotary drill machine etc., and the lubrication of working arm pin shaft is adopted
Use lubricating grease.In engineering machinery work progress, the lubricating grease on working arm in each pin shaft to some extent will be by silt, ash
The influence of the various impurity intrusions such as dirt, moisture, while causing lubricating grease generally to leak because poorly sealed or temperature rise is excessively high
Phenomenon.In order to guarantee that pin shaft and shaft room keep good lubricating oil film, each pin shaft on working arm is needed continually to inject newly
Lubricating grease, and leak lubricating grease can not collect.If the biological degradability of lubricating grease is poor, the lubricating grease of leakage if, can be right
Construction environment causes different degrees of pollution.For drinking for the special constructions environment such as Hydraulic Projects, golf course, due to
Mankind's daily life or activity etc. are closely related, it is desirable that use Biodegradable Lubricating Greases, to avoid or utmostly reduce profit
Consistent lubricant pollution on the environment.
Engineering machinery operation under outdoor open-air atmosphere, temperature can from -20 DEG C of winter low temperature with down toward 80 DEG C of summer high temperature with
On, while the harsh conditions of heavy load, impact or shock load are subjected to, this requires lubricating grease must also have excellent subtract
The performances such as mill property, antioxidant, adhesion and resistant of high or low temperature.
The Biodegradable Lubricating Greases of the prior art, although the biodegradable rate of portioned product can reach 65% or more,
But its anti-attrition, antioxidant, high and low temperature are poor, product is easy to run off, and service life is short.Existing defect is mainly shown as
Four ball milling spot diameters >=0.58mm, Oxidation Resistance Test pressure drop >=49kPa, evaporation capacity >=0.46%, wastage >=0.7g, water leaching
Number of dropouts >=2%, winter construction cause to add lubricating grease difficulty because of the similar large viscosity of low temperature.Especially with containing organic
Phosphorus, heavy metal lead, benzene ring type compounds additive when, then bigger damaging effect is often brought to environment.It can be seen that existing
Technical products are not able to satisfy engineering machinery and change setting under the execution conditions such as rouge period in claimed environment, reduction leakage, extension
Standby lubrication.
Adding III class oil of hydrogen is natural crude oil by being hydrocracked and the techniques such as hydrofinishing, and a kind of obtained chemical composition
More pure base oil.This base oil and the I class base oil ratio obtained by the traditional handicrafts such as solvent refining, solvent dewaxing
Compared with cryogenic property being improved, and the poisonous and harmful constituent content such as aromatic hydrocarbons, colloid, asphalitine is lower, to the bad shadow of environment bring
Sound is smaller.Vegetable oil has the characteristics that biological degradation rate, low temperature resistant, lubricity is good.Using suitable proportion plus III class oil of hydrogen with
Vegetable oil is used in combination, and can obtain the more preferably grease base oil such as biological degradability, lubricity and lower temperature resistance.
In order to improve the oxidation stability of lubricating grease, traditional technology is using amine or phenolic antioxidant.But these add
Add agent while improving the oxidation stability of lubricating grease, and can increase because of the residual of the compounds such as amine or phenols to ring
The pollution in border.Thiodipropionate antioxidant itself not only has good antioxidant, but also non-toxic, and own biological degradation rate
Height is suitable as the antioxidant of biodegradable engineering machinery lubricating grease.
Graphite is common lubricating grease anti-friction composition, and environmental sound.But the antifriction effect of general graphite is poor, no
The lubricating requirement being able to satisfy under engineering machinery harsh conditions.Lubrication is added in the fluorographite that graphite obtains after fluorination treatment
Its Wear vesistance can be significantly promoted in rouge, to meet lubrication of engineering machinery under the conditions of sharp pounding and impact load
It is required that.
Environment-friendly type tackifier such as polymethacrylates, natural rubber etc., the existing good feature of environmental protection, and lubrication can be improved
The adhesion of rouge can achieve the sealing effect for improving engineering machinery lubricating grease, reduce the purpose of lubricating grease leakage.
Using vegetable oil with plus III class of hydrogen oil mixture oil based on oil, 12-OH base stearic acid lithium soap be thickening agent, simultaneously
Fluorographite anti-friction composition, thiodipropionate antioxidant and environment-friendly type tackifier are compounded, there is high biodegrade to be made
Property and good anti-attrition, antioxidant, resistant of high or low temperature, adhesion engineering machinery lubricating grease, there is no open report at present.

It puts into kettle, cooling material;When temperature reaches 85~120 DEG C, fluorographite is added, thiodipropionate antioxidant, gathers
Methacrylic acid ester additive;It stirs evenly, kettle can be gone out, obtain finished product after three-roll grinder is ground.
7. the engineering machinery lubricating grease with high biological degradability such as claims 1 or 2 avoids environment dirt for requiring
Lubrication of bull-dozer, excavator or the loading machine to work under the conditions of dye in -20~120 DEG C of temperature ranges.
