Abstract

The invention discloses a powder metallurgy lubricating agent. Polyvinyl isobutyl ether, metallic oxide particles, zinc stearate and fatty acid bisamide are proportionally mixed to be prepared into lubricating agent particles, wherein the lubricating agent particles comprise components in percentages as follows: 33%-37% of polyvinyl isobutyl ether, 13%-15% of metallic oxide particles, 8%-10% of zinc stearate and 45%-48% of fatty acid bisamide; and the lubricating agent particles contain micro wax powder and are covered with paraffin layers. With the adoption of the scheme, the lubricating agent particles of the powder metallurgy lubricating agent contain various lubricating ingredients and are more easily and uniformly distributed in a powder material, the lubricating agent particles are covered with the paraffin layers, and the paraffin layers are broken in the compaction process, so that demoulding can be smoothly performed.

Description

A kind of powder metallurgy lubricant
Technical field
The lubricant formulations design field that the present invention relates to adopt in powder metallurgy, particularly relates to a kind of powder metallurgy lubricant.
Background technology
Powder metallurgy is a kind of taking metal-powder as raw material, and repressed and sintering is made the working method of various goods.The essence advantage of powdered metal parts production technique is to have Quick-forming ability and the material high utilization rate of complicated shape.
Powder metallurgical technique comprises three key steps, and first, chief component material is broken down into the powder of various fine particle compositions; Then, pack powder into mold cavity, impose certain pressure, form the pressed compact with required part shape and size; Finally, pressed compact is carried out to sintering.For the demoulding of the better fusion of fine particle and pressed compact, conventionally in starting material, add lubricant.For the demoulding of changing, in part material, added multiple lubricant, multiple lubricant with the process of material mixing in easily cause the situation of skewness and part demoulding difficulty, the incomplete rate of pressed compact is high.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of powder metallurgy lubricant, integrated multiple Lubrication Composition in particle, easily and powdered material fully mix, the pressed compact stripping result of making is good.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of powder metallurgy lubricant is provided, proportionally be mixed and made into lubricant particle by polyvinyl ethyl isobutyl ether, metal oxide microparticle, Zinic stearas and lipid acid bisamide, in described lubricant particle, the shared proportion of each composition is respectively: polyvinyl ethyl isobutyl ether 33 ~ 37, metal oxide microparticle 13 ~ 15, Zinic stearas 8 ~ 10 and lipid acid bisamide 45 ~ 48, in described lubricant particle, be provided with micro-wax powder, described lubricant particle appearance is covered by paraffin layer.
In a preferred embodiment of the present invention, described metal oxide microparticle is a kind of or its mixture in silicon oxide, aluminum oxide or calcium oxide.
In a preferred embodiment of the present invention, described paraffin layer is that paraffin powder is wrapped in described lubricant particle surface heating and merges and form.
The invention has the beneficial effects as follows: a kind of powder metallurgy lubricant that the present invention points out, in lubricant particle, contain multiple Lubrication Composition, more easily be uniformly distributed in powdered material with lubricant particle, lubricant particle appearance is covered by paraffin layer, in the process of pressed compact, paraffin layer is destroyed, is conducive to the smooth demoulding.
Embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of powder metallurgy lubricant, proportionally be mixed and made into lubricant particle by polyvinyl ethyl isobutyl ether, metal oxide microparticle, Zinic stearas and lipid acid bisamide, in described lubricant particle, the shared proportion of each composition is respectively: polyvinyl ethyl isobutyl ether 33 ~ 37, metal oxide microparticle 13 ~ 15, Zinic stearas 8 ~ 10 and lipid acid bisamide 45 ~ 48, in described lubricant particle, be provided with micro-wax powder, described lubricant particle appearance is covered by paraffin layer.
In lubricant particle, contain multiple Lubrication Composition, proportioning is clear, adds more convenient.Lubricant particle is uniformly distributed with cylinder in powdered material, and at high temperature decomposes rear and powdered material fusion, and the paraffin layer of lubricant particle appearance is destroyed in the process of pressed compact, and paraffin layer is transferred on mould, is conducive to the smooth demoulding of pressed compact.
In a kind of powder metallurgy lubricant of the present invention, add especially metal oxide microparticle, described metal oxide microparticle is a kind of or its mixture in silicon oxide, aluminum oxide or calcium oxide, in the process of pressed compact, lubricant particle is destroyed, metal oxide microparticle wherein can reduce the friction between powdered material, improves the closely knit situation of pressed compact.
Further, described paraffin layer is that paraffin powder is wrapped in described lubricant particle surface heating and merges and form, and paraffin layer decomposes in the process of pressed compact, improves on the one hand the intensity of pressed compact, and the paraffin layer on pressed compact surface is conducive to the demoulding on the other hand.
In sum, a kind of powder metallurgy lubricant that the present invention points out, compares with common lubricant, and composition is various, be conducive to improve compaction rate and the intensity of pressed compact, and stripping result is good, applied widely.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
