Embodiment Construction

[0018] An anti-oxidation manganese-containing copper alloy powder prepared by a water mist method is characterized in that it is prepared from the following components: 500 parts of raw copper powder, 25 parts of zinc powder, 8 parts of manganese powder, and 5 parts of salvianolic acid , 4 parts of thymol, 8 parts of diallyl sulfide.

[0019] A kind of anti-oxidation manganese-containing copper alloy powder prepared by water mist method is characterized in that, it is prepared through the following steps:

[0020] (1) Use intermediate frequency melting equipment for melting

[0021] Adjust the intermediate frequency power to 40kw oven for 20 minutes, adjust to 60kw oven for 20 minutes, then adjust to 100kw oven until the bottom of the furnace turns red; adjust the intermediate frequency power to 200kw, add copper powder until it is completely melted, then add tin and phosphorus in turn ; After all the raw materials are melted, adjust the intermediate frequency power to 100kw,...

Abstract

Antioxidative manganiferous copper alloy powder prepared by a water mist method is characterized in that the powder is prepared from the following ingredients: 500 parts of raw copper powder, 25-30 parts of zinc powder, 8-10 parts of manganese powder, 3-7 parts of danshinolic acid, 3-7 parts of thymol and 6-8 parts of diallyl sulfide. Raw materials are smelted by intermediate frequency smelting equipment first; the contents of copper, zinc and manganese to achieve lead freeness of the product; the copper alloy powder is subjected to oxidation resistance treatment, so that the oxidation resistance of the copper alloy powder is improved; and the prepared antioxidative manganiferous copper alloy powder has the characteristics of good sphericity, uniform ingredients, good moldability, excellent sinterability and low surface oxidation, and is low in production cost, high in production efficiency and stable in product quality.

Description

technical field [0001] The invention relates to the field of powder metallurgy, and relates to a method for preparing anti-oxidation manganese-containing copper powder and copper alloy powder by using a water mist method. Background technique [0002] Traditional copper alloy powder is composed of copper, lead, tin, zinc (or phosphorus). Because it contains lead, it is poisonous to the human body and pollutes the environment. Lead and its compounds are toxic to various tissues of the human body. The poisoning route can be Its vapor or dust is inhaled by the respiratory tract, and then the phagocytes in the respiratory tract quickly bring it to the blood; or it is absorbed through the digestive tract and enters the blood circulation to cause poisoning. With the increasing awareness of environmental protection and their own health requirements and the popularization of mechanized transportation, production and daily life tools, people realize that the waste generated during th...
