Description
Technical field
The present invention relates to a kind of lubricating composition, and in particular to a kind of to be used for the lubricant oil composite that core takes processing technology.
Background technology
With the development of optical technology, modern camera lens has high requirement for the optical property and outward appearance of eyeglass, and
Core takes for processing special substance and has the eyeglass of flat surface, often in flat surface is difficult to accomplish effective management and control in appearance,
Main cause is that general core takes cutting oil to be extremely difficult to reason for the lubrication and cooling-down effect during whetslate processing platform face
Want to claim, cause eyeglass flat surface to there is small broken phenomenon to occur, white point graininess is presented after inking, influence product appearance, very
The spuious optical phenomenon of camera lens can be extremely caused to occur.
The content of the invention
It is used for the lubricant oil composite that core takes processing technology it is an object of the invention to provide a kind of, it can promote processing
During whetslate and eyeglass platform lubrication, while taking away the heat produced in processing.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of to be used for the lubricant oil composite that core takes processing technology, its is composed of the following components：65 ~ 75wt% of base oil, emulsification is multiple
15 ~ 25wt% of mixture, 5 ~ 15wt% of antirust agent, 5 ~ 10wt% of capturing agent of chlorine, total mass fraction is 100%；
Further, it is composed of the following components：Base oil 70wt%, emulsifies complexing agent 17wt%, antirust agent 8wt%, the capturing agent of chlorine
5wt%, total mass fraction is 100%.
Wherein base oil is No. 32 nonstandard oil；
Further, the feature described in base oil is that the kinematic viscosity at 40 DEG C is 30~50mm2/ s light lubricating oils.
Wherein emulsification complexing agent is made up of chlorination stearic acid, long chain fatty acids and triethanolamine；
Further, emulsification complexing agent is according to mass ratio 5 by chlorination stearic acid, oleic acid and triethanolamine:5:7 compositions.
Wherein antirust agent is from sulfonate and chlorinated paraffin composition；
Further, antirust agent is according to mass ratio 4 by petroleum sodium sulfonate, calcium mahogany sulfonate and chlorinated paraffin:2:2 mixing systems
.
The capturing agent of wherein chlorine is epoxidized vegetable oil,
Further, epoxidized vegetable oil is epoxidized soybean oil；
Described is used for the preparation method that core takes the lubricant oil composite of processing technology：
First base oil is added in Mixer pot, agitator stirring is started, adds antirust agent, be sufficiently stirred for 10 ~ 20 minutes；Successively
The capturing agent of emulsification complexing agent and chlorine is added, stirs 10 ~ 20 minutes, that is, obtains brownish red uniform liquid；
Application method：The lubricant oil composite that the above has reconciled is taken, and adds 10 ~ 20 times of the water equivalent to composition gross mass
Mixed, obtained uniform liquid can be used for core and take processing to use, wherein allotment ratio is then ground according to eyeglass material
Consumption degree is different and does correspondence increase and decrease；The replacement cycle of lubricant oil composite：3 days or 5000 ~ 8000 processing capacities.
The remarkable advantage of the present invention is：
（1）A kind of light for taking the lubricant oil composite of processing technology for core, can to process rear lens of the present invention
Cleanliness and dimensional accuracy comply fully with requirement；Cooling preferably, the heat produced in honing process can be taken away in time, extend whetslate
With lathe service life, and the generation of eyeglass white point particle is reduced；Good resistance to rust and corrosion, workpiece, whetslate and lathe
Metal surface is bright, does not change colour and corrosion phenomenon；
（2）The lubricating composition of the present invention has a splendid lubricant effect and cooling-down effect, and with washing, anti-corrosion, surely
The performance such as fixed.Feature is specially：Lubrication, it is ensured that surface processing accuracy and finish；Precipitability is cleaned, in time cleaning
The glass powder of whetslate is attached to, whetslate performance and life-span is effectively improved；Splendid rust-preventing characteristic, protects board not by corrosion；It is low
Foam, facilitates look at glass lens machining status；
（3）Kinematic viscosity of the base oil described in such scheme at 40 DEG C is 30~50mm2/ s, when the Basic oil Viscosity too
Gao Shi, the glass dust after processing is easy to stick on whetslate surface, influences whetslate cutting force, easily causes eyeglass platform colourless
The generation of point, and when viscosity is too low, lubricant effect is not obvious, the lens surface processed is coarse, and whetslate loss is very fast；
（4）Lubricant oil composite of the present invention can significantly improve processing technology, it is ensured that disposable yield；And it is steady to increase raising processing
It is qualitative, lift processing efficiency；Reduce bad probability, reduction production cost and later stage corresponding cost.
Brief description of the drawings
Eyeglass VL2307 G1 after the processing of the sample of 1 application method of Fig. 1 embodiments 1；
Eyeglass VL2307G1 after Fig. 2 original cutting oil processing.
Embodiment
For the further open rather than limitation present invention, below in conjunction with example, the present invention is described in further detail.
Embodiment 1
A kind of to be used for the lubricant oil composite that core takes processing technology, its is composed of the following components：Base oil 70%, emulsifies complexing agent
