Description

Trace spray supply type cutting oil and preparation method thereof
Technical Field
The invention relates to the technical field of lubricating oil, in particular to trace spray supply type cutting oil and a preparation method thereof.
Background
In metal cutting, a metal cutting oil is generally used, and the purpose of the oil is to extend the life of tools used for machining, such as a drill, a milling machine, a cutter, and a grinder, to improve the surface accuracy of a workpiece, and to improve machining efficiency, thereby improving productivity of machining.
However, in the metal working and cutting process, due to the reasons of transportation, use, leakage, sputtering, natural replacement and the like, cutting oil is inevitably and directly discharged into the environment, and people are more and more aware of the harm of metal working lubricants to human bodies and the environment along with the continuous enhancement of the awareness of environmental protection and energy conservation of human beings. Therefore, the manufacturing technology of the cutting oil which is pollution-free and environment-friendly becomes the research focus of the lubricating oil industry in the 21 st century.
In order to protect the environment and reduce the cost, since the middle of the nineties, the dry cutting technology has been rapidly developed, and the dry cutting is a cutting method for cutting without using a cutting fluid and without using a cooling fluid. The dry cutting has the advantages of no pollution to the environment, no harm to the human body, clean formed cuttings, easy recovery, no cutting fluid and related cost, and the like. However, dry cutting requires a tool having a high performance and a refrigeration facility, which increases the total cost, and therefore, dry cutting has drawbacks of lack of lubricity, high cutting temperature, and the like in terms of practical use. The quasi-dry cutting technique can meet the processing requirement and can also reduce the cost related to the cutting fluid to the minimum. A spray cutting method in which cutting oil and compressed air are sprayed in the form of mist to a cutting region is representative of a quasi-dry cutting method.
Therefore, it is of particular importance to develop and develop a trace amount of spray-fed cutting oil having a small amount of use, good lubricity, and a low residual rate.
Disclosure of Invention
In view of the above, the invention provides a volatile atomizing cutting oil, which is composed of isoparaffin as base oil, and isooctyl sulfide, trihydroxyl ester and a sulfide extreme pressure agent. The cutting oil has better lubricating property, does not remain on the surface of a workpiece, and the workpiece is easy to clean; the flash point is higher, the evaporation loss is less, the product color is light yellow, no peculiar smell is generated, and the smoke around the processing machine tool is less.
In order to achieve the purpose, the invention adopts the following technical scheme:
a trace spray supply type cutting oil comprises the following raw materials in percentage by weight: 65-83.7% of isoparaffin, 3-8% of isooctyl sulfide, 8-20% of trihydroxy ester, 5-15% of extreme pressure vulcanizing agent and 0.3-2% of anti-smoke agent.
Preferably, the sulfurized extreme pressure agent is one or two of sulfurized lard and sulfurized rapeseed oil.
Preferably, the isoparaffin is selected from fractions with flash points between 100 and 110 ℃.
Preferably, the anti-aerosol agent is selected from ethylene propylene copolymer, hydrogenated styrene copolymer or polyisobutylene.
The invention also provides a preparation method of the trace spray supply type cutting oil, which comprises the following steps: adding isoparaffin into a preparation tank according to the weight percentage, starting a stirrer for stirring, then adding isooctyl sulfide, trihydroxyl ester, a sulfide extreme pressure agent and an anti-aerosol agent, stirring at room temperature until the oil liquid is light yellow, and packaging after the oil liquid is qualified through inspection.
Preferably, the stirring speed is 50-150 rpm.
Preferably, all the raw materials are added and stirred for 20-50 minutes.
Compared with the prior art, the invention has the following beneficial effects:
(1) the product of the invention is disposable trace cutting oil, and the cutting oil is atomized by a machine tool atomization device and then sprayed on the surface of a workpiece to play a role in lubricating and cooling. The workshop has no waste liquid and waste oil discharge, meets the requirement of environmental protection, reduces the discharge of waste liquid and is beneficial to environmental protection.
(2) The invention ensures that the product has excellent lubricating property through the synergistic action among all the additives, can be suitable for metal cutting processing of most materials and is mainly used for oil mist lubrication. The gas-liquid two-phase oil mist can play a role in lubrication, can take away a large amount of heat and can reduce the use amount of cutting fluid. In the cutting process of the spray supply mode, the using amount of the cutting oil is very small, which is equivalent to 1/10000 of the using amount of the traditional pouring mode, so that the process requirement can be met by using a very small amount of the cutting oil when the cutting spray oil is used for cutting and supplying the difficult-to-machine materials, and the use cost of the machining lubricating oil can be reduced due to the very small using amount.
(3) The sulfurized fat is a biodegradable extreme pressure antiwear additive, and both the sulfurized lard and the sulfurized rapeseed oil are easily biodegradable, have no pollution to the environment, have low toxicity and low harm to human bodies and ecological environments, and meet the requirements of related environmental indexes.
(4) The cutting oil prepared by the invention has low residual rate of below 0.01 percent, does not remain on the surface of a workpiece, and is easy to clean the workpiece.
(5) The cutting oil prepared by the invention has higher flash point and less evaporation loss, and the product is light yellow in color due to the selection of the isoparaffin, has no peculiar smell, has less smoke around a processing machine tool, reduces the risk of sucking harmful substances by operating personnel, and creates a good operating environment for the operating personnel.
(6) The cutting oil provided by the invention is simple in preparation method, does not need high temperature, and can be mixed at normal temperature.
