Description
Technical field
The present invention relates to the production technical field of copper powder, particularly relate to a kind of water fog method and produce the compound anti-of copper powder
Oxidant.
Background technology
Copper powder is one of raw material basic in powder metallurgy, be widely used in automobile, motorcycle, oiliness bearing,
The numerous areas such as electrical alloy, electronic information, electrical carbon product, oil drilling, chemical industry synthesis, diamond composition
In.The development of powder metallurgy industry at any time, powder metallurgy range of application expanding day, kind and the matter to powder
The requirement of amount is more and more higher.Produce copper powder many employings electrolysis at present, but electrolysis environmental pollution be serious,
Energy consumption is big, cost is high, and product is single, and electrolytic copper powder poor fluidity, it is impossible to meet high-performance powder metallurgy
The demand of product.Atomization produces copper powder low cost, efficiency is high, environmental pollution is little.But traditional water smoke
During the copper powder that metallization processes produces, oxidizable during winding-up, the copper powder oxygen content produced can be caused high,
Powder particle is thicker, it is impossible to adaption demand.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of water fog method produces the compound anti-of copper powder
Oxidant, reasonable mixture ratio, during water fog method prepares copper powder, at Copper Powder Surface while supplementary set free radical
Film forming plays the effect of duplicate protection, reaches good antioxidant effect, is effectively improved the oxidation resistance of copper powder,
Solve the problem that the oxygen content of water atomization production copper powder is higher.
The present invention adopts the following technical scheme that to achieve these goals
A kind of water fog method produces the composite antioxidant of copper powder, is made up of the component of following weight portion: benzene a pair of horses going side by side three
Nitrogen azoles 1-10 part, benzene sulfonic acid sodium salt 1-10 part, lauryl sodium sulfate 1-10 part, OP surfactant 2-20
Part, glycerine 3-25 part, water 20-50 part.
Preferably, described water fog method produces the composite antioxidant of copper powder, by the component group of following weight portion
Become: benzotriazole 3-7 part, benzene sulfonic acid sodium salt 3-7 part, lauryl sodium sulfate 3-7 part, OP surface-active
Agent 8-15 part, glycerine 10-20 part, water 30-40 part.
Preferably, described water fog method produces the composite antioxidant of copper powder, by the component group of following weight portion
Become: benzotriazole 5 parts, benzene sulfonic acid sodium salt 5 parts, lauryl sodium sulfate 5 parts, OP surfactant 10
Part, glycerine 15 parts, 35 parts of water.
Compared with the prior art, beneficial effects of the present invention is as follows:
The composite antioxidant of the water fog method production copper powder of the present invention, employing said components formula, reasonable mixture ratio,
During water fog method prepares copper powder, while supplementary set free radical, play duplicate protection in Copper Powder Surface film forming
Effect, reaches good antioxidant effect, is effectively improved the oxidation resistance of copper powder, solves water atomization and produces
The problem that the oxygen content of copper powder is higher；Wherein benzotriazole is combined formation deposition guarantor with the copper ion of copper superficial layer
Cuticula, benzene sulfonic acid sodium salt plays synergy with benzotriazole, is adsorbed in copper surface with polar group, catches up with copper removal
Surface moisture, suppresses relevant material transport, plays capture-effect；Lauryl sodium sulfate plays emulsification,
The emulsification of other corrosion inhibiter and solvent strengthened by OP surfactant, improves the wettability of copper powder；Glycerine permutation table
Face moisture content, and other one layer of low molecule very thin films layer is formed on surface.The present invention produces copper powder as in water atomization
Antioxidant, use the antioxidant of the present invention, the copper powder oxygen content that water smoke produces less than 0.08%, contains
Oxygen amount is up to state standards, and solves the problem that water atomization copper powder content is higher, extends the copper powder shelf-life.
