Description
Technical field
The present invention relates to a kind of graphite ene-type liquid hardening cooling medium and preparation method and application.
Background technology
The various parts overwhelming majority of composition mechanized equipment are required for processing through quenching and tempering just can be possessed required by people
Physics, chemistry and mechanical property.
Quenching process is that steel-iron components is heated to high temperature (> 850 DEG C) carry out austenitizing, then it is immediately placed in cooling medium
In (water, oil), it is desirable in very short time (0～several seconds), high temperature (850 DEG C～1050 DEG C) metal parts is cooled to
About 300 DEG C, to avoid the austenite transformation to non-martensite；Below 300 DEG C, it is desirable to be cooled to room temperature with cooling rate more slowly,
With avoid austenite to martensite transfor mation time structural stress and the deformation that causes of thermal stress and cracking.Only meet such bar
Part, the mechanical performance being just satisfied with most and the parts of minimal deformation.
Traditional liquid hardening cooling medium typically has two classes: a class is simple tap water or contains the water base of various additives
Quenching liquid；Another kind of is simple mineral oil or the mineral oil containing various additives.
The cooling characteristics of water is: not enough in hot stage (steam blanket) cooling capacity, the highest in cold stage cooling capacity,
Therefore, handled part the most easily produces soft spots, has again the biggest deformation, even ftractures.Various interpolation is added in water
After agent, this situation makes moderate progress, but effect is unsatisfactory.And in use, additive therein is easy
Occur chemical reaction to change character thus change the characteristic of water-based hardening liquid, thus it is old in use to need close tracking and monitoring
Change deterioration, use and manage relatively costly.
The cooling characteristics of oil is: compare cooling characteristics slowly although having at cold stage, but at the cooling energy of hot stage
Power is also significantly less than the expected value of people.Little at the parts quenching deformation ratio water of oil quenching, but there is lower hardness, harden
The defect that layer is shallower.After adding various additive in oil, this situation makes moderate progress, but effect is unsatisfactory.And
And in use, additive therein is susceptible to chemical reaction change character thus changes the characteristic of oil base quenching liquid,
Thus in use need its aged deterioration situation of close tracking and monitoring, use and manage relatively costly.
In a word, above-mentioned quenching medium has the disadvantage in that
The shortcoming of water:
High temperature section cooling rate is slow, and low-temperature zone cooling rate is fast, causes part soft spots and strain cracking, and percent defective is the highest.Various water base quench
Fire liquid easily produce rotten, aging, poisonous, irritant, have pollution etc..It addition, the cooling of water and water-based hardening liquid is special
Property is the most sensitive to the change of water temperature, and this is the key factor causing being deformed with the part of step, groove and hole class.
The shortcoming of oil:
High temperature section cooling is slow, quenches a lot of steel grades and does not gets angry；Easily there is cracking and polymerization and oxidation deterioration, the most aging, workpiece
Drag-out lossy is serious, quenching time oil smoke is the most seriously polluted, production environment severe, costly.
Traditional liquid cooling medium also has a kind of fatal defect, it is simply that the height that its cooling capacity varies with temperature and changes is quick
Perception.The consequence that this characteristic causes is: when processing the part with step, groove and hole class, due to these position liquid
The flowing of body is hindered and makes its temperature raise (heat conduction herein is not gone out), causes liquid cooling characteristics herein to occur
Changing makes cooling capacity be greatly reduced, thus produces soft spots and deformation.This is the obstacle that traditional liquid hardening media cannot overcome.
Above-mentioned medium common defects also has: rotten and aging in order to tackle, need to often measure viscosity, acid number, ash, composition,
Cooling towers group and it is frequently necessary to whole updating quenching liquid etc., causes that to use and manage cost high.
Problem on deformation produced by traditional liquid cooling medium can also be tolerated for the part that some precision are relatively low, and to the modern times
For substantial amounts of precision manufactureing, owing to the material property of traditional liquid cooling medium is determined, no matter add which kind of additive also
It is difficult to the particular attribute changing its liquid substance when cooling, thus its quenching cooling characteristics and stress deformation effect are difficult to reach
Gratifying effect, although its deficiency is made moderate progress by various additive, but simultaneously with side effect.
Chinese patent application CN 104059618 A discloses a kind of electromotor graphene oxide water-free cooling and preparation method thereof,
Electromotor graphene oxide water-free cooling is 30 by percentage by weight～the ethylene glycol of 65%, percentage by weight be 30～

Infusion and percentage by weight be 0.7～8% composite corrosion inhibitor be mixed and stirred for uniformly i.e. obtaining water-free cooling to dissolving.This is cold
But the most aqueous in liquid, and have multiple components mixed configuration to form, cost is high, and stability is poor, only can be suitably used for electromotor,
The scope of application is narrow.

Rule constraint, and use saltatory and non-confinement heat transfer；2) fluctuation between fluid is strengthened with whirlpool；3) lamellar is divided greatly
Son can relax Transverse Temperature Gradient between fluid.Therefore, Graphene is best suited for as cooling medium.
In water, group water solution or mineral oil, add Graphene micro powder granule, utilize the impayable heat conductivity of Graphene, can
To produce Fast Cooling effect.Owing to Graphene granule is evenly distributed in the solution of water or oil, its maximum conductive force is permissible
Whole solution is made to obtain the temperature of high uniformity, so that each microcosmos area of solution has identical cooling capacity, Jin Erke
So that each position of complicated shape part can obtain uniformly cooling and homogeneous performance.
Graphite ene-type liquid quenching medium is in addition to above-mentioned major advantage, compared with traditional liquid hardening media, owing to quenching is cold
But, during, the maximum conductive force of the most equally distributed Graphene granule can make the temperature high uniformity of whole liquid,
Therefore can aging with delays liquid, increase the service life, cost-effective.
