The diamond grinding fluid has the advantages of high grinding efficiency, environment-friendliness, and low cost.
Description
Technical field
The present invention relates to Sapphire Polishing Technology field, especially, relate to a kind of sapphire and polish special diamond grinding liquid and system thereof
Preparation Method.
Background technology
Diadust is a kind of ultra-fine abrasive material with high rigidity and good mechanical physical property, and its profile is spherical or elliposoidal,
Will not scratch for grinding and polishing and be ground body, be widely used to different processing polished fields, particularly superfinishing the most at present
Close surface finish manufacture field.Diadust can as the polishing material of the hard material such as gem, generally can be made into aerosol,
The polished product such as oiliness or waterborne liquid, aerosol, due to shortcomings such as precipitation of easily stammering, difficult dispersion and waste are bigger, limits it
Range of application.What research was more at present is oiliness lapping liquid and aqueous polishing liquid, and oiliness lapping liquid lubricates relative to aqueous polishing liquid
Performance is good, and grinding speed is fast, and rate stabilization also has cooling down effect, and aqueous polishing liquid is easily caused in process of lapping
There is big cut in workpiece, and suspension stability is poor, and therefore, the application of oiliness lapping liquid is the most extensive.
But oiliness lapping liquid of the prior art exist diamond dust easily precipitate, polishing efficiency low, it is impossible to reach preferable removal
Amount and surface roughness requirements, and have corrosivity, and stink is serious, and a series of shortcomings such as environmental pollution is the biggest.
Summary of the invention
Present invention aim at providing a kind of sapphire to polish special diamond grinding liquid and preparation method thereof, grind solving existing oiliness
The technical problem that in mill liquid, diamond dust easily precipitates.
For achieving the above object, the invention provides a kind of sapphire and polish special diamond grinding liquid, including diamond micropowder, Bai Kuang
Oil and vegetable oil, the proportion of composing of three is: white mineral oil: vegetable oil: diamond micropowder=10-40ml:15-45ml:0.3-1.2g.
Preferably, described white mineral oil: vegetable oil: diamond micropowder=10-30ml:20-35ml:0.3-0.9g.
Preferably, the particle diameter of described diamond micropowder is 2～8 μm.
Preferably, described vegetable oil is Oleum Arachidis hypogaeae semen.
The preparation method of above-mentioned diamond grinding liquid, including step:
After diamond micropowder, white mineral oil and vegetable oil are stirred in proportion, divide under the ultrasound condition that frequency is 25～30kHz
Dissipate 15～60min, obtain diamond grinding liquid.
Preferably, the temperature of ultrasonic disperse is 30-40 DEG C.
Preferably, first the part white mineral oil after diamond micropowder and filtration treatment is stirred；Again by vegetable oil and remaining white ore deposit
Oil is poured in the diamond micropowder stirred, and continues stirring.
Preferably, above-mentioned steps adds for the first time diamond micropowder and the ratio of white mineral oil are 1g:5-10ml.
The method have the advantages that
The sapphire of the present invention polishes special diamond grinding liquid and have employed white mineral oil and the vegetable oil carrying liquid as diamond micropowder,
Diamond micropowder compounds good dispersion in dispersion at white mineral oil and vegetable oil, and suspension stability is good, and grinding efficiency is high, environmental protection
And low cost.
White mineral oil, calls paraffin oil, white oil, mineral oil, is by the mixture of oil gained refine liquid hydrocarbon, the most saturated
Cycloalkane and alkane mixture, molecular weight is the most all within the scope of 250-450.By crude oil through normal pressure and vacuum fractionation, molten
Agent extracting and dewaxing, hydrofinishing and obtain.White mineral oil clear appearance liquid, colorless and odorless, flash-point are high, to light, heat, acid etc.
Stable；Autoignition temperature arrives 260-371 DEG C, and its burning-point is far above kerosene, safe to use under room temperature；And viscosity (motion
Viscosity: 50 DEG C is 5.7～26mm2/ s) than kerosene (dynamic viscosity: 40 DEG C is 1.0～2.0mm2/ s) high, the lapping liquid of allotment
Concentration is higher than the lapping liquid concentration of kerosene allotment, so grinding efficiency is higher；The condition of sapphire straight body position processing request can be met
Under realize sapphire fast polishing.
Dynamic viscosity refers to the ratio of dynamic viscosity and the density of equality of temperature same pressure fluid, and its numerical value is the highest, then explanation viscosity is the highest.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.Below
The present invention is further detailed explanation.
Detailed description of the invention
Hereinafter embodiments of the invention are described in detail, but the present invention can according to claim limit and cover multiple
Different modes is implemented.
A kind of sapphire polishes special diamond grinding liquid, and proportion of composing is white mineral oil: vegetable oil: diamond micropowder=10-40ml:
15-45ml:0.3-1.2g.
Preparation method is:
1, first being precipitated by white mineral oil, the filtration gauze re-using 200 mesh filters, and takes filtrate stand-by；
2, diamond micropowder is poured beaker into, add the part white mineral oil after filtration treatment, stir with agitator；Add white
Dormant oils is to be in harmonious proportion uniformly by diamond micropowder, can refer to 1g diamond micropowder and adds the ratio mediation of 5-10ml white mineral oil；
3, vegetable oil and remaining white mineral oil are poured in the diamond micropowder stirred, continue to stir；
4, the beaker that will be equipped with stirred mixed liquor is placed in ultrasonic wave concussion device, uses the supersonic frequency of 25kHz～30kHz,
Shaking 15-60 minute, the temperature in ultrasonic wave concussion device maintains 30-40 DEG C, i.e. obtains diamond grinding liquid.
Vegetable oil is the oils and fats obtained from the fruit of plant, seed, plumule, is liquid under room temperature, as Oleum Arachidis hypogaeae semen, Oleum Glycines,
Oleum lini, Oleum Ricini, Oleum Brassicae campestris etc., all can use.The diamond grinding liquid that said method prepares, yield can reach 98.5%
