A kind of metal drawing powder and preparation method thereof

Abstract

The invention discloses metal spinning powder and a preparation method thereof. The metal spinning powder is characterized by being prepared from the following raw materials in parts by weight: 100-300 parts of sodium carbonate or potassium carbonate, 1-5 parts of sodium benzoate, 300-600 parts of water, 10-60 parts of sulfonated castor oil, 5-30 parts of chlorcosane, 5-30 parts of tall oil, 2-15 parts of powdery sodium hydroxide or potassium hydroxide, and 5-30 parts of white carbon black. The invention also discloses the preparation method of the metal spinning powder. The metal spinning powder disclosed by the invention has the advantages of favourable lubricating property, corrosion resistance, high temperature resistance, high pressure resistance, lower cost and easy storage.

Description

technical field [0001] The invention relates to a wire drawing production process used in the metal wire drawing process, in particular to a metal wire drawing powder in the metal drawing process and a preparation method thereof. Background technique [0002] The wire drawing process is a metal processing process, even if the metal is compressed by an external force to obtain a technical processing method that meets the size and shape requirements. In the process of metal drawing, wire drawing powder is a necessary process lubricant material. Its main function is to reduce the friction damage to the drawn metal and the mold, ensure the quality of the wire drawing of the product, and prolong the service life of the mold. [0003] The brushed treatment can make the metal surface obtain a strong metallic texture, which has a very strong decorative effect. The drawn metal material has the advantages of good rust resistance, wear resistance and bright appearance. It is durable a...

Problems solved by technology

[0004] The main components of the wire drawing powder that have occurred on the market are lime, water, animal oil, paraffin, soap, stearic acid, talcum powder and alkali, as the patent that the authorized announcement number is CN 1164380 C discloses a kind of metal wire drawing powder, the Although the patent has changed the previous acid-drawing composition, due to technical limitations, the acid-drawing composition used in actual production will still damage the surface structure of the material and reduce the strength and toughness of the material surface. In addition, the lime used in its selection contains a large amount of Impurities need to be screened during subsequent processing, which is time-consuming and labor-intensive. The selected paraffin contains polycyclic aromatic hydrocarbons and polycyclic aromatic hydrocarbons. Such carcinogens are extremely difficult to degrade and eliminate, and will cause chronic damage to the human body.
