Abstract

The invention provides a preparation method of nano-copper modified alloy tableware, and relates to the technical field of nano-copper. The effects of enhancing the strength and toughness of the tableware, reducing the heat conductivity of the tableware and enhancing the oleophobicity and hydrophobicity of the tableware are achieved. The preparation method of the nano-copper modified alloy tableware comprises the following steps that S1, nano-copper is modified and reduced through a chemical reduction method to be reduced and grown into nano-copper metal powder; S2, the nano-copper metal powder and zinc oxide are put into a crucible to be subjected to high-temperature melting, and therefore an alloy solution is obtained; and S3, the alloy solution obtained after high-temperature melting ispoured into a tableware mold. According to the preparation method of the nano-copper modified alloy tableware, the nano-copper is reduced and then mixed with zinc to obtain the nano-copper-zinc alloyto manufacture tableware, semi-finished tableware is heated, kept warm and cooled again, the nano-copper has good ductility and plasticity, and the nano-copper-zinc alloy mixed with the zinc has excellent mechanical performance and corrosion resistance. And the toughness of the tableware can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of nano copper, in particular to a method for preparing nano copper modified alloy tableware. Background technique [0002] Nano-copper is an article made of nano-materials. It has superplastic ductility and is a pure substance. Articles made of nano-materials have many peculiar properties. For example, nano-copper has superplastic ductility and can be Elongated more than 50 times without cracks. Researchers from the French National Research Center found that the average volume of copper nanocrystals with an average volume of only 80 nanometers has amazing mechanical properties. The strength is not only three times higher than that of ordinary copper, but also the deformation is very uniform without obvious areas. Narrowing phenomenon, tableware refers to non-edible tools that directly contact food during meals, utensils and utensils used to assist food distribution or food intake, with the development of so...
