Description
Technical field
The invention belongs to lapping oil technical field, refer more particularly to a kind of compound method of emulsion resistance lapping oil.
Background technology
The effect that lapping oil plays in mechanical processing process is cooling, lubricated, antirust, clean, especially plays a key effect to the surface figure accuracy, dimensional precision and the surfaceness that improve workpiece.Workpiece will, through corase grind, precision grinding process, generally directly grind without cleaning and drying afterwards before grinding, and at this moment workpiece surface can more residual grinding fluids, and wherein water and surfactant can cause the emulsification of lapping oil.
In the time that the resistance to emulsion of lapping oil is lower, it is large that lapping oil viscosity after emulsification becomes, fluid from water sample when emulsification is serious all can produce a large amount of foams to the cream frost of thickness, the contamination precipitations such as the fine grinding bits, emery wheel or oilstone end and the dust that at this moment produce in process of lapping swim in less than bottom lapping oil above, have a strong impact on precision and the surfaceness of workpiece, shorten work-ing life because lapping oil causes to go bad simultaneously, accelerated the replacement cycle.
So far, about the related data that improves lapping oil resistance to emulsion has no relevant report.
Summary of the invention
For improving the resistance to emulsion of lapping oil, the invention provides a kind of compound method of emulsion resistance lapping oil, the emulsion resistance lapping oil making according to compound method has higher resistance to emulsion, the workpiece that is particularly suitable for containing surfactant and water is roughly ground or is refined, avoid emulsion resistance lapping oil to produce emulsification or foaming phenomenon, improve grinding precision and the surfaceness of workpiece, extended the work-ing life of emulsion resistance lapping oil.
In order to realize foregoing invention object, the present invention adopts following technical scheme:
A compound method for emulsion resistance lapping oil, contains base oil, non-emulsifying agent, rust-preventive agent and lubricant in emulsion resistance lapping oil, compound method of the present invention is as follows:
Base oil is made up of 5# white oil and kerosene, and non-emulsifying agent is T1001, and rust-preventive agent is made up of petroleum sodium sulfonate and dodecenylsuccinic acid, and lubricant is boric acid ester;
By weight the 5# white oil of 10～20 parts is joined in reactor and be heated to 110～120 DEG C and make its dehydration, when 5# white oil temperature in question response still drops to 80 DEG C by the petroleum sodium sulfonate of 3～5 parts, the dodecenylsuccinic acid of 0.5～1.5 part, the non-emulsifying agent T1001 of the boric acid ester of 5～10 parts and 0.2～1 part together joins in reactor and stirs it is dissolved completely, when solute temperature in question response still drops to 40 DEG C, again the kerosene of 70～80 parts is joined in reactor and stir and obtain elementary lapping oil, when being down to room temperature, filters again described elementary lapping oil, after filtration, can obtain emulsion resistance lapping oil.
Owing to adopting technical scheme described above, the present invention produces following beneficial effect:
