Description
Technical field
The present invention relates to field of powder metallurgy, relate to using water fog method to prepare the antioxidative copper powder containing manganese 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 antioxidative copper alloy powder containing manganese 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 antioxidative containing the copper alloy powder of manganese, it is characterised in that its prepared by following component and
Become: raw material copper powder 500 parts, zinc powder 25-30 part, manganese powder 8-10 part, salvianolic acid 3-7 part, thymol 3-7 part, diallyl sulfur
Ether 6-8 part.

(2) hydraulic atomized process
In atomization process, jet apex angle is 40-45 degree, and nozzle material is No. 45 steel, and bottom pour ladle aperture is 5-8mm, and atomizing pressure is
18-25Mpa, the height of atomization bucket is 3m, and chilled water is 0.3-0.5m；
(3) secondary-atomizing
One secondary cold water atomizer is set at 0.5cm～2cm below water atomizing nozzle again, carries out secondary-atomizing；
(4) vacuum suction filter
Vacuum suction filter is carried out after atomization, atomized water and copper alloy powder, during vacuum suction filter, red phenol in vacuum suction filter bucket
Acid, thymol, allyl sulfide；Atomized water recycles after treatment, the copper alloy powder obtained, and is dried,
Sieve.
The present invention is by first carrying out melting to raw material copper powder, zinc powder, manganese powder, and by allotment copper, zinc, the content of manganese, real
Show the unleaded of product, reduce cost；By adding salvianolic acid, thymol, diallyl sulfur in vacuum suction filter bucket
Ether, improves the antioxygenic property of copper alloy powder；Antioxidative prepared by the present invention copper alloy powder granule even containing manganese,
And oxygen content is low, there is good intensity, heat conductivity, wearability and color and luster.
