Abstract
The present invention relates to cutting liquid for precision-threading, which is characterized in that refined mineral oil is used as base oil, and a set of compound additives are added in the base oil. The compound additives are prepared from maize oil, phenyltriazolyl fatty amine, chlorowax and petroleum sulfonate. The cutting liquid has the advantages of good abrasion-resisting performance, high electrode-pressing resistance, no smelly odor and no toxicity, and the present invention can be suitable for the cutting liquid for precision-threading ring gauges and can also be used as the lubricating cooling liquid for precision-finishing such as drilling, gear-slotting, gear-hobbing, etc.
Description
The present invention relates to a kind of cutting fluid that is used for the finish turning screw thread.
Present domestic finish turning thread ring gauge operation adopts vegetables oil to do metalworking coolant, and its lubricity is better, and is nontoxic, have no irritating odor, but because of it is an edible oil, the source of goods is few, and purposes is wide, the price height, easy in addition again deterioration by oxidation, easily gum deposit easily produces grease, all brings difficulty for the cleaning of maintenance, maintenance and the workpiece of lathe, the cleaning of environment, the washing of operator's working suit are also increased trouble, and vegetables oil life-time service acid number increases influences rust-preventing characteristic.
Once developed various prescription abroad, as US3,909,429, US4,416,788, JP58-74796 etc., these cutting fluids mostly contain sulphur, phosphorus compound, and are poisonous, and irritating smell is arranged.
The purpose of this invention is to provide a kind of novel cutting lubricant for precision-threading, make it to have higher last non seizure load and lower frictional coefficient, no stink, nontoxic, and improve the rust-preventing characteristic of cutting fluid, the property cooled off, oxidative stability, cleaning.
Main points of the present invention are to have found a kind of prescription that can improve the cutting lubricant for precision-threading of cutting fluid lubrication performance and nontoxic, no stink.This cutting fluid is a base oil with mineral oil, is added with composite additive in the base oil, and composite additive is made up of reactant, clorafin and the barium mahogany sulfonate of Semen Maydis oil, 124 Triazole aliphatic amide.
Base oil of the present invention is selected refined mineral oil for use, and does not adopt the finished product machinery oil, because some additive (as alkylnaphthalene) is still not unnecessary in the finished product machinery oil, and in use also can produce irritating smell.
The composite additive that adds above-mentioned component in the base oil, with regard to the good cutting fluid of energy obtained performance, particularly wherein the reactant of oiliness improver 124 Triazole aliphatic amide and the compound use of anti-wear agent clorafin have significant synergism, and last non seizure load can improve 10 kilograms.
Cutting lubricant for precision-threading each component content weight percent of the present invention is:
Form content (weight) %
Semen Maydis oil (industrial goods) 1～15
The reactant of 124 Triazole aliphatic amide (industrial goods) 0.03～0.3
Clorafin (industrial goods) 2～10
Barium mahogany sulfonate (industrial goods) 0.1～3
The refined mineral oil surplus
The preparation of cutting lubricant for precision-threading is finished by following technology.
1, the ratio in prescription takes by weighing each component.
2, the refined mineral oil of adding 3/5 in reactor, and add barium mahogany sulfonate, under constantly stirring, slowly be heated to 110 ℃～120 ℃, the barium mahogany sulfonate dissolving is mixed, stop to heat.
3, in reactor, continue to add 1/5 refined mineral oil, constantly stir its temperature is descended, when treating that mixing oil in the still is cooled to 80 ℃～90 ℃, add the reactant of 124 Triazole aliphatic amide, stir.
4, in reactor, add remaining refined mineral oil, constantly stir, make its constant temperature, add clorafin, add the back and stir insulation 30 minutes at 70 ℃～80 ℃ at 70 ℃～80 ℃.
5, in reactor, add Semen Maydis oil, stir, promptly get cutting lubricant for precision-threading after filtration.
Cutting fluid of the present invention can replace vegetables oil, is applicable to the metalworking coolant of finish turning thread ring gauge, also can be as precision machined metalworking coolants such as brill, gear shaping, gear hobbing, broaching, tapping.The main quality index of this cutting fluid is listed in the table 1.
The present invention has following advantage compared with the prior art:
1, lubricity is good, can replace vegetables oil, and its correlation data is listed in table 2, the table 3.
2, the rust-preventing characteristic of cutting lubricant for precision-threading, cooling property, cleaning, oxidative stability all are better than vegetables oil, and its correlation data is listed in table 4.
3, can save vegetables oil, thereby further satisfy the people's lives needs.
4, cutting fluid of the present invention does not have stink, nontoxic, and cleaning is good, can improve operator's working conditions.
From following embodiment, can further understand characteristic feature of an invention.
