Description
Technical field：The invention belongs to powdered metallurgical material production technical field, and in particular to a kind of novel powder
Powder metallurgy material and preparation method thereof.
Background technology：At present, powder metallurgy is mostly that zinc stearate and graphite are added in iron powder, is passed through
Special-purpose machinery batch mixer, is mixed to prepare the powder of powder compacting at normal temperatures for a long time.Wherein Hard Fat
Sour zinc is lubricant in the material, and effect is to reduce
When frictional force, and zinc stearate needs all to remove in product sintering circuit, its existing problem one
It is：Zinc stearate powder and graphite powder are differed greatly with the proportion of iron powder, are mixed with the mode of machinery,
Deposit uneven components upon mixing and product compacting after composition segregation phenomenon, cause compacted products quality
It is unstable, affect the mechanical performance of product；Two is the working environment in batch mixing and product pressing process
There is more dust, easily cause environmental pollution；Three is the zinc stearate fusing point in the sintering circuit of product
At 120 DEG C or so, remove that it is very inconvenient, and sinter that programming rate is fast, product is easy to foaming to be easily caused report
It is useless, cause certain waste；During four are sintering process, zinc stearate volatile matter severe contamination burner hearth,
On inboard wall of burner hearth, the short time forms the hard fouling of thickness, it is necessary to which blowing out is removed, and removing is totally stranded very much
Difficulty, has a strong impact on the life-span of normal production and sintering furnace Muffle.
The content of the invention：It is an object of the invention to provide a kind of composition is uniform, product quality is stable, low cost,
Novel powder metallurgy material of environmentally safe and preparation method thereof.
The technical scheme is that：A kind of novel powder metallurgy material, it is characterized in that by following component by
Weight portion is constituted：80-100 mesh iron powder 99-101, graininess paraffin 0.8-1.2, graphite 0.6-1.0.
A kind of preparation method of novel powder metallurgy material, is characterized in that comprising the following steps that：Will be upper
State composition to be put in the mixing equipment of automatic temperature control heating, temperature mixes 45-60 minutes at 79-81 DEG C,
Room temperature will be cooled to after the taking-up of well-mixed powder again.
Due to adopting above-mentioned technical proposal, zinc stearate is instead of with graininess paraffin, mixture temperature is
79-81 DEG C, and paraffin melting point is 60 DEG C or so, it is uniform after long-time is blended, is paraffin melting to wrap up
Iron powder surface, graphite also can be bonded on paraffin, make mixing process be changed into small quantity of fluid solid with a large amount of
Body powder glues mutually mixed process, is wrapped in metal powder surface together, solve in mixing process by
In the batch mixing problem of non-uniform that powder proportion differs greatly and produces, after also solving product compacting, composition is inclined
The problem of analysis, improves the mechanical performance and quality of product, and be bonded in iron powder surface graphite and
Paraffin is difficult for drop-off, effectively prevent the problem that powdered graphite flies upward, and improves batch mixing and compacting operation
Environment；And paraffin melting point is low, easily remove during sintering, due to being uniformly distributed, sintering do not occur
The phenomenon of product foaming, it is ensured that the qualification rate of product,
Technical scheme is described in further details below in conjunction with specific embodiment.
Specific embodiment：
Embodiment 1：A kind of novel powder metallurgy material and preparation method thereof, by what is constituted by weight
80 mesh iron powders 99, graininess paraffin 1.2, graphite 0.6 are put in the mixing equipment of automatic temperature control heating,
Temperature mixes 60 minutes at 79 DEG C, then is cooled to room temperature after well-mixed powder is taken out.
Embodiment 2：A kind of novel powder metallurgy material and preparation method thereof, by what is constituted by weight
100 mesh iron powders 101, graininess paraffin 0.8, graphite 1.0 are put in the mixing equipment of automatic temperature control heating,
Temperature mixes 45 minutes at 81 DEG C, then is cooled to room temperature after well-mixed powder is taken out.
Embodiment 3：A kind of novel powder metallurgy material and preparation method thereof, by what is constituted by weight
90 mesh iron powders 100, graininess paraffin 1.0, graphite 0.8 are put in the mixing equipment of automatic temperature control heating,
Temperature mixes 52.5 minutes at 80 DEG C, then is cooled to room temperature after well-mixed powder is taken out.
Claims (2)
