Water-based metal wire drawing liquid with good lubricating effect and preparation method thereof

Abstract

The invention discloses a water-based metal wire drawing liquid with a good lubricating effect. The water-based metal wire drawing liquid is characterized in that the water-based metal wire drawing liquid is prepared from the following raw materials in parts by weight: 3-4 parts of sodium ricinoleate soap, 1-2 parts of coconut diethanolamide, 1.5-2 parts of polyepoxysuccinic acid, 5-7 parts of sulfurized lard oil, 3-4 parts of polyethylene glycol, 3-4.5 parts of sodium hydrogen carbonate, 3-5 parts of chlorinated paraffin, 3-4 parts of spindle oil, 2-4 parts of sodium carboxymethyl cellulose, 0.8-1.5 parts of sodium benzoate, 5-7 parts of additives and 900-950 parts of deionized water. The water-based metal wire drawing liquid disclosed by the invention has excellent lubricating performance and can meet the requirements of customers on brightness and dimensional precision at relatively low concentration; by adding the additives, the water-based metal wire drawing liquid has good wear resistance, dispersion, lubrication and film-forming property, is mutually matched with a surfactant, and can form a protective film on the surface of a metal to realize a corrosion inhibition effect. The water-based metal wire drawing liquid adopts a water-based formula, is good in cooling property and cleaning property, is easy to be moved after processing, and further ensures the cleanliness of a wire drawing operation environment.

Description

technical field [0001] The invention relates to the technical field of wire drawing, in particular to an aqueous metal wire drawing liquid with good lubricating effect and a preparation method thereof. Background technique [0002] There are currently three types of wire drawing lubricants commonly used in the market, namely soluble soap, saponified oil, and synthetic lubricants. Soluble soap is formed by the reaction of animal and vegetable oils or fatty acids equal to inorganic bases or organic bases. With the prolongation of use time, strong bases will be produced after hydrolysis, and 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 copp...

Soluble soap is formed by the reaction of animal and vegetable oils or fatty acids equal to inorganic bases or organic bases. With the prolongation of use time, strong bases will be produced after hydrolysis, and 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
