Description
Technical field
The present invention relates to a kind of friction improver for lubricating oil, and in particular to a kind of cycloalkanes-yttrium tungsten silicon titanium calcium friction
Modifier and its production method.
Background technology
During machine operation, fretting wear is the natural phenomena of generally existing, the friction loss world about 1/3rd
=energy, abrasion is to cause material and one of damage of facilities and three kinds of most important forms of failure.Modern times friction research table
Bright, the 1/3-1/2 of energy is to be wasted in a variety of manners in frictional dissipation in the world, and economic loss is very big, by taking automobile as an example, hair
The power that motivation is sent only has 1/3 to reach ground, and remaining power is consumed in self friction.Mitigate self friction consumption, hair
Motivation is just greatly improved using power, so as to reach the effect of energy-conservation.Have in addition to frictional dissipation, during various mechanical abrasions
Occur.Show according to relevant information, energy loss caused by mechanical wear is 5-25 times of friction loss.Add at machine operation position
Plus-minus rub, antiwear additive come mitigate mechanical wear loss, the prolonged mechanical life-span, increase effective operation time all be energy-conservation important ring
One of section.
The abrasion that mechanical part is too fast is prevented, then needs to establish oil film between two slidingsurfaces, there is adequate thickness
Oil film separates the relative mechanical part surface slided, and the purpose of abrasion is reduced with regard to that can reach.Lubrication is then to reduce friction, reduce
Or the most effective technology of abrasion is avoided, lubricating oil is used in all kinds mechanically to reduce friction, protection machinery and workpiece
Fluid lubricant, mainly play lubrication, cooling, antirust, cleaning, sealing and buffering etc..Lubricating oil contains base oil and added
Add agent, friction improver is a kind of additive of lubricating oil, is used for moving component when adding friction improver in conventional foundation oil
Between when, from the point of view of physical property friction improver can significantly reduce contact surface coefficient of friction.Friction improver generally contains
Polarized group, mainly adsorbed by polar group in metal surface, form the diaphragm of similar cushion pad by friction surface
Separate the effect for reaching and reducing abrasion；Adsorbed film can be divided into physical absorption and chemisorbed again, and physical absorption is main
It is to lean on intermolecular active force, and chemisorbed then adsorbs friction improver in metal surface also by the way that chemical reaction occurs,
So that adsorption effect is more preferable.Common friction improver mainly has carboxylic acid and its derivative, acid amides, acid imide, amine and its derivative
Thing, phosphorus and phosphoric acid derivatives and organic polymer and organo-metallic compound.Friction improver master in current practice
There are two types, when organic friction modifiers, second, metal class especially organic metal molybdenum class friction improver.It is organic to rub
Wiping modifier is generally divided into the chemical reaction film with saturated fatty acid, phosphoric acid and D2EHDTPA and sulfur-bearing aliphatic acid etc. for representative
Class, and the physical absorption film class with long-chain carboxylic acid, amino-compound, acid imide etc. for representative, and with unsaturated complex ester, different
Butenoate etc. polymerize species for the formation of representative.Organic metal molybdenum class friction improver can be largely classified into not phosphorous, sulphur class
Organic metal molybdenum and phosphorous, sulphur class organic metal molybdenum；Conventional not phosphorous, sulphur organic-molybdenum is mainly complicated aluminium amines,
Phosphorous, sulphur class organic metal molybdenum is mainly molybdenum dialkyl-dithiophosphate and molybdenum dialkyldithiocarbamacompositions etc..
The fuel economy of engine lubricating oil is lifted by adding friction improver, helping, which reduces abrasion, saves energy
Source, it is an important directions of future development；However, containing S, although the friction improver of the element such as P has excellent friction
Performance is learned, can but be brought than more serious etching problem；The friction of organic metal molybdenum class improves
Although agent improves the antifriction performance of oil product, but organic molybdenum additive of the prior art is in extremely harsh work
Under the conditions of work, as performance under the conditions of high temperature and top load is bad, maximum nonseizure load（PB）Do not make us with antiseizing full yet
Meaning.
