Abstract
Copper and copper alloy pipe, rod, line drawing are a kind of soluble oils with lubricator.It is good that it has lubricity, and drawing force is little, and pass deformation is big, the goods surfaces externally and internally is highly polished, do not pollute characteristics such as product surface during annealing, can replace widely used full oil type lubricant---rape oil at present, and can eliminate rape oil to the pollution of environment with to the corrosion of equipment.
Description
The present invention relates to the lubricant that drawing copper and Cu alloy material are used.
For reduce copper and copper alloy tube, rod, the wire rod cold drawing adds the friction resistance in man-hour and makes copper material keep bright and clean surface quality, develop and use cheap, high-quality lubricant to be absolutely necessary.Present domestic most copper processing enterprise still uses rapeseed oil to stretch with lubricator as copper material, has minority enterprise to adopt the emulsion lubrication that contains paraffin.The rapeseed oil costliness, resource-constrained, lubricity is not good enough, and the severe contamination production environment, equipment such as corrosion cable; Contain the surface quality that paraffin wax emulsions has worsened copper material.Now have only a few enterprise from external import lubricant, but search the composition less than the import lubricant, technical information such as compound method are not found its patent yet.The disclosed lubricant of Japanese Patent J60032895, J60032896 is to be used for copper and copper alloy rolling processing, and the lubricant of definitely saying so and using when being used to batch rolling good copper material is different with the water-soluble emulsion lubricant that uses in the drawing copper material process.
The objective of the invention is to seek a kind of when drawing copper and copper alloy tube, rod, wire rod high lubricating effect, working modulus is big, does not pollute the copper material surface, the lubricant of etching apparatus not, and require raw material inexpensive, abundant is to replace present widely used rape oil fully.
Content of the present invention: with Oleum Gossypii semen 50～70%(weight percentage, as follows) and animal oil 0～5% as base oil (total oil mass be not more than 70%), add ethanol 15～25%, water 10～30% under the condition that has sodium hydroxide 2～5% to exist, is allowed to condition under 70～100 ℃ of temperature and reacts, add glycerol 2～7% then, continue reacting by heating, add small amount of antioxidant at last, stirring promptly gets the present invention.
The antioxidant of above-mentioned adding can be a benzotriazole, add-on 0.05～0.3% also can be a bisphenol, as pyrocatechol, Resorcinol, add-on 0.1～0.5% perhaps adds benzotriazole 0.05～0.3% and a kind of bisphenol 0.1～0.5% simultaneously.
Several embodiments of the present invention are listed as into table 1, and its temperature of reaction is controlled at 70～100 ℃, fully stir in the reaction.
Lubricant effect of the present invention is investigated, and compared with rape oil and a kind of import lubricant simultaneously.The main performance index of investigating the lubricant lubricant effect is drawing force and reduces deflection.Drawing force is carried out on universal testing machine.When coefficient of extension is identical, high lubricating effect, drawing force is little, on the contrary drawing force is big.The pull-out test situation sees Table 2.
Reduce deflection and represent, see Table 3 with the average decrement of test.The lubricant lubricity is good, and decrement is big, otherwise decrement is little.
From table 2, table 3 as seen, lubricant effect of the present invention is better than the sort of import lubricant, more is better than rape oil.
The lubricated tensile copper material any surface finish situation of the present invention is also investigated.Rape oil tensile copper material sees that through the annealing rear surface vestiges oil spot phenomenon is arranged, and tensile copper material of the present invention has been eliminated this phenomenon, and any surface finish, color even, and in the test of stretching Hsn70-1A prolong, surperficial qualification rate brings up to 91.3% by 30.6% of rape oil.
Aspect cooling performance and since the present invention when using water be mixed with emulsion, cooling performance is also much better than rape oil during stretching, uses the present invention's copper material that stretches to eliminate rape oil fully to the pollution of environment with to the corrosion of equipment.
It is all abundant to prepare raw material of the present invention, uses the present invention than using the rape oil saving and lubricates expense more than 30%.
