Description
Technical field
The present invention relates to field of powder metallurgy, relate to using water fog method to prepare the phosphorous copper powder of antioxidative and copper alloy powder
Method.
Background technology
Traditional copper alloy powder is made up of copper, lead, stannum, zinc (or phosphorus), due to containing lead, toxic to human body,
Have pollution, lead and its compound tissue each to human body the most toxic to environment, route of intoxication can have respiratory tract to suck its steam
Or dust, then in respiratory tract phagocyte by its rapid band to blood；Or absorb through digestive tract, enter blood circulation and occur
Poisoning.The raising day by day environmental protection consciousness and own health required along with people and mechanization traffic, production and daily
Popularizing of life instrument, it was recognized that various instrument in use produced refuse is to human body and the pollution of environment,
The all parts that it is desirable to used instrument is all environmentally friendly machine.Therefore copper alloy powder unleaded becomes development
Inevitable.
Preparing copper powder with atomization, its medium has two kinds, and one is gas, especially noble gas, prepares the micro-of powder delivery
It is nearly regular spherical for seeing pattern, and oxygen content ratio is relatively low, if atomization process control fine, the copper powder powder prepared can
To be directly over being sieved into product, but production cost is higher, and requires higher to safety precautions.Another kind is water, though
So production cost is low, safety is high, but the copper powder of output not only oxygen content is high, and microscopic appearance is irregular, has pattern
The industry of high requirement cannot meet needs.
The patent No. 200810072435.1 discloses a kind of novel copper-base alloy powder, and its formula forms by weight percentage
For: bismuth 1-15%, stannum 0.5-10%, zinc 0.3-15%, surplus is copper.Its manufacture method is: first put in high-frequency melting furnace by copper,
After fusing, it is being sequentially added into stannum, bismuth, zinc, all after fusing also mix homogeneously, is being poured in filter bag, sprays through chevron nozzle, and
It is ground into powder, drying by High-Pressure Water.This patent replaces lead due to this copper-base alloy powder bismuth, the most leaded, right
Human non-toxic's evil, environmentally safe, is a kind of environment-friendly type copper-base alloy powder.But bismuth is rare metal, adds undoubtedly
Substantial amounts of cost.
Summary of the invention
The purpose of the present invention is aiming at the deficiency that above-mentioned prior art exists, it is provided that a kind of low cost, safety is high, contain
The method that oxygen amount is low, the phosphorous copper alloy powder of antioxidative is prepared in the water atomization of powder body microscopic appearance rule.
It is an object of the invention to be achieved through the following technical solutions.
A kind of water fog method prepares the copper alloy powder that antioxidative is phosphorous, it is characterised in that its prepared by following component and
Become: raw material copper powder 500 parts, glass putty 25-30 part, phosphorus powder 8-10 part, benzotriazole 3-7 part, benzene sulfonic acid sodium salt 3-7 part, glycerol 6-8
