Problems solved by technology

At present, powder metallurgy materials with iron powder as the main component are the most widely used and the most widely used. However, the existing powder metallurgy formulations and processes still have limitations, and the many process steps lead to waste of energy and low production efficiency. , the product also has the problem of low tensile strength and hardness. At the same time, with the continuous development of industry, the performance requirements for this type of material are getting higher and higher. Not only powder metallurgy materials with excellent physical properties are required, but also To further improve the chemical properties of the material, one important aspect is the corrosion resistance and anti-rust performance of the material, so further research and development of products that meet the requirements are required

Abstract

The invention discloses a preparation method of an antirust powder metallurgy material. The preparation method comprises the following steps that firstly, copper powder, iron powder, zinc powder, glass fibers and carbon powder are stirred and mixed in a mixing device so as to obtain a mixture I; then aluminum oxide, epoxy resin, calcium oxide, lecithin and 3-acrylamide-based propyl dimethyl ammonium chloride are added into the mixture I, heating is carried out under a vacuum condition, and heat preservation is carried out for certain time to obtain a mixture II; then the mixture I and the mixture II are mixed, and grinding and mixing are carried out by using a ball mill to obtain a mixture III; the mixture III is pressed in a mold to obtain a blank material; and finally, the blank materialis fed into a sintering furnace for sintering to obtain the antirust powder metallurgy material. The material obtained by using the preparation method has good mechanical property and corrosion resistance.
