Description
Technical field
The present invention relates to Sapphire Polishing Technology fields, particularly, are related to a kind of special diamond grinding liquid of sapphire polishing
And preparation method thereof.
Background technology
Diadust is a kind of ultra-fine abrasive material with high rigidity and good mechanical physical property, shape be it is spherical or
Elliposoidal will not scratch for grinding and polishing and be ground body, therefore be widely used to different processing polished fields at present, special
It is not ultra-precision surface polishing field.Diadust can usually may be used as the polishing material of the hard materials such as jewel
The polished products such as aerosol, oiliness or waterborne liquid are made, aerosol is due to precipitation of easily stammering, difficult dispersion and wastes larger etc. lack
Point, limits its scope of application.It is oiliness lapping liquid and aqueous polishing liquid to study at present more, and oiliness lapping liquid is with respect to water
Property lapping liquid greasy property it is good, grinding speed is fast, and rate stabilization simultaneously has cooling down effect, and aqueous polishing liquid is ground
It is easy to cause workpiece in journey and big cut occurs, suspension stability is poor, and therefore, the application of oiliness lapping liquid is relatively extensive.
But there are diamond dusts easily to precipitate, polishing efficiency is low for oiliness lapping liquid in the prior art, is unable to reach reason
Think removal amount and surface roughness requirements, and there is corrosivity, stink is serious, and environmental pollution is especially big etc. a series of scarce
Point.
Invention content
Present invention aims at a kind of sapphires of offer to polish special diamond grinding liquid and preparation method thereof, existing to solve
The technical issues of diamond dust easily precipitates in oiliness lapping liquid.
To achieve the above object, special diamond grinding liquid is polished the present invention provides a kind of sapphire, including diamond micro mist,
The composition ratio of White Mineral Oil and vegetable oil, three is：White Mineral Oil：Vegetable oil：Diamond micro mist=10-40ml：15-45ml：0.3-
1.2g。
Preferably, the White Mineral Oil：Vegetable oil：Diamond micro mist=10-30ml：20-35ml：0.3-0.9g.
Preferably, the grain size of the diamond micro mist is 2~8 μm.
Preferably, the vegetable oil is peanut oil.
The preparation method of above-mentioned diamond grinding liquid, including step：
After diamond micro mist, White Mineral Oil and vegetable oil are stirred evenly in proportion, in the ultrasound condition that frequency is 25~30kHz
15~60min is to get diamond grinding liquid for lower dispersion.
Preferably, the temperature of ultrasonic disperse is 30-40 DEG C.
Preferably, first diamond micro mist and the part White Mineral Oil after filtration treatment are stirred evenly；Again by vegetable oil and residue
White Mineral Oil pour into the diamond micro mist stirred evenly, continue to stir.
Preferably, the ratio for the diamond micro mist and White Mineral Oil that above-mentioned steps are added for the first time is 1g：5-10ml.
The invention has the advantages that：
The sapphire of the present invention polishes special diamond grinding liquid and uses White Mineral Oil and vegetable oil holding as diamond micro mist
Carrier fluid body, diamond micro mist good dispersion in White Mineral Oil and vegetable oil compounding dispersion, and suspension stability is good, grinding efficiency
Height, it is environmentally friendly and at low cost.
White Mineral Oil, alias paraffin oil, white oil, mineral oil are the mixtures of the refining liquid hydrocarbon obtained by oil, predominantly full
The cycloalkane and alkane mixture of sum, molecular weight is usually all within the scope of 250-450.By crude oil through normal pressure and decompression point
Evaporate, solvent extraction and dewaxing, hydrofinishing and obtain.White Mineral Oil clear appearance liquid, colorless and odorless, flash-point be high, to light, heat, acid
Deng stabilization；Autoignition temperature reaches 260-371 DEG C, and burning point is far above kerosene, safe to use at room temperature；And viscosity (fortune
Kinematic viscosity：50 DEG C are 5.7~26mm2/ s) than kerosene (dynamic viscosity：40 DEG C are 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 higher；The item of the straight body position processing request of sapphire can be met
Sapphire fast polishing is realized under part.
Dynamic viscosity refers to ratio of the dynamic viscosity with equality of temperature with the density of pressure fluid, and numerical value is higher, then explanation is glutinous
Degree is higher.
Other than objects, features and advantages described above, the present invention also has other objects, features and advantages.
The present invention is further detailed explanation below.
Specific implementation mode
The embodiment of the present invention is described in detail below, but the present invention can be limited and be covered according to claim
Multitude of different ways implement.
A kind of special diamond grinding liquid of sapphire polishing, composition ratio is White Mineral Oil：Vegetable oil：Diamond micro mist=10-
40ml：15-45ml：0.3-1.2g.
Preparation method is：
1, first White Mineral Oil is precipitated, the filtration gauze for reusing 200 mesh is filtered, and takes filtrate for use；
2, diamond micro mist is poured into beaker, the part White Mineral Oil after filtration treatment is added, is stirred evenly with blender；It is added
White Mineral Oil is to reconcile diamond micro mist uniformly, can refer to 1g diamond micro mists and the ratio of 5-10ml White Mineral Oils is added to reconcile；
3, vegetable oil and remaining White Mineral Oil are poured into the diamond micro mist stirred evenly, continues to stir evenly；
4, the beaker equipped with stirred mixed liquor is placed in ultrasonic oscillation device, using the ultrasound of 25kHz~30kHz
Frequency is shaken 15-60 minute, and 30-40 DEG C of temperature in ultrasonic oscillation device maintenance is to get to diamond grinding liquid.
Vegetable oil is the grease obtained from the fruit, seed, plumule of plant, is liquid under room temperature, such as peanut oil, beans
