Problems solved by technology
Soluble soap is formed by the reaction of animal and vegetable oils or fatty acids equal to inorganic or organic bases. With the prolongation of use time, strong bases will be produced after hydrolysis. The water-soluble pH value is as high as about 10. Free bases in the manufacturing industry will absorb Carbon dioxide reacts chemically with the copper powder in the drawing solution; saponified oil is a mixture of neutral fat and soluble soap in proportion, because its aqueous solution contains soluble soap, and the soluble soap will be hydrolyzed as the use time prolongs, The basic copper carbonate and copper soap are produced in the wire drawing liquid, which destroys the balance of lipophilicity and hydrophilicity of the surface active substances in the saponified oil, resulting in a decrease in emulsification ability, a decrease in lubricity, pollution of the wire mold, and blockage of the die hole; synthetic lubrication The lubricant uses synthetic emulsifiers instead of soluble soap for emulsification, cleaning, and dispersion. The emulsification effect is good, the foam is less, and the cooling and cleaning performance is good. However, the disadvantage of synthetic lubricants is that they will absorb carbon dioxide in the air and generate basic carbonates. , so that the lubricity is not ideal enough

Abstract
The invention relates to a micro emulsion semisynthetic copper wire drawing liquid composition, which comprises the following components in percentage: 10% to 30% of base oil, 25% to 50% of compound emulsifying agent, 5% to 20% of pH conditioning agent, 0.3% to 1% of copper corrosion inhibitor, 10% to 20% of water-soluble lubricant, 0.05% to 0.15% of foam killer and the balance of purified water. The copper wire drawing liquid provided by the invention is characterized in that the compound emulsifying agent and the base oil are adopted to produce microemulsion; then, the microemulsion is compounded in the water-soluble lubricant to form micro emulsion semisynthetic copper wire drawing liquid composition with excellent lubricating property for copper wire drawing processing. The copper processed by adopting the composition has the advantages that the copper product has a shining surface, the die has a long service life, the composition has better cooling property to prevent a tool and a workpiece from sintering as compared with that lubricated by wire drawing oil, the work environment is better, no oil mist is generated, the health of working personnel can be ensured and the like. Therefore, the environmental pollution caused by oil processing is reduced, and the processing cost is effectively decreased.
Description
technical field [0001] The invention relates to a metalworking fluid composition for copper wire drawing, which has excellent lubricity and defoaming performance, and can meet the requirements of smoothness of copper wire and protection of factory environment. Background technique [0002] In the copper wire drawing process of my country's cable industry, copper material and enameled wire industry, there are generally phenomena such as oxidative discoloration and blackening, which are more serious in spring and summer. With the popularity of existing high-speed machines, the drawing speed has been greatly improved, and the contradictions have become more and more prominent. There are many kinds of lubricants used for copper wire drawing, and their performance varies greatly. Some wire drawing lubricants will turn black and smelly during use. There are also some copper wire drawing lubricants that have adverse conditions such as increased tensile force, increased friction, i...
