Description
Technical field
Formula of composite powder and preparation method thereof is polished with carrying magnetic the present invention relates to a kind of MRF.
Background technology
MRF polishes the curved surface polishing to be overcome to conventional planar, there is provided overall technique is reformed, with
Constantly bringing forth new ideas for workpiece, has played great effect.Magnetorheological devices are main to be polished cell body by work piece holder, band magnetic force and is thrown
Light powder and slurry are constituted, then when being polished, using magnetic-adsorption band magnetic force polishing powder, workpiece are pressed on what polishing powder, are done and are revolved
Turn workpiece is carried out it is smooth, while workpiece is played polishing (adding lustre to) act on.Owner will be using magnetic force by again in polishing process
Close powder and fix what bottom, formation can throw the burnishing surface of curved surface, then with the engineering plastics and polishing powder in composite powder composition, to workpiece
Get leveling and highlighting process.
MRF has played very big key effect to curved surface polishing technique, and carrying magnetic polishing composite powder and slurry are even more
The core of the technique, carrying magnetic polishing composite powder and slurry are good to improving polishing speed, precision in technique to traditional magnetic powder
Rate, even more a quantum jump.
The existing Magnaglo of tradition is not protected, and slurry has necessarily influence, polishing condition on it, and particle size does not have can
Scalability is low to workpiece requirement conformability.Also having some has a way coated to particle, but still with the life-span is shorter, bag
Cover the defects, such as Northeastern University's Master's thesis such as rear removal force difference particle diameter is non-adjustable and workpiece requirement degree of conformity is low, not recyclable
《The synthesis of reduced iron powder Magnetorheologicai polishing liquid and performance study》Described in the cladding to reduced iron powder be using silane coupled
Agent is that surfactant prepares well mixed with isopropanol as solvent again, and effect is to improve its dispersion effect in carrier fluid,
Do not change Magnaglo polishing efficiency, yield, and particle size itself does not have adjustable, it is poor for applicability；Grinding in addition
The active ingredient in composite powder is polished in polishing process and can increase over time to act on and gradually decayed, and magnetic property can produced
Raw influence.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of carrying magnetic polishing composite powder, except possessing magnetic conductive material or magnetic
Property material outside, have certain protection and lifting magnetic powder life-span to magnetic conductive material or magnetic material, possess removal force outer to work
Part further reduces scuffing, and adjustable granularity is high to workpiece requirement degree of conformity, and carrying magnetic polishes composite powder more for that can return
The property received, overcomes many defects of conventional magnetic powder.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：Carrying magnetic polishes composite powder and its preparation side
Method, carrying magnetic polishing composite powder, it is characterised in that：Obtained by following mass ratio formula and method：
Formula
Magnaglo content 60%-80%；
Engineering plastics content is 5%-10%；
Polishing powder content 5%-10%；
Plasticizer about total amount 1.5%-2%；
Preparation method：
First, it is formulated according to it, with engineering plastics as carrier, adds Magnaglo, polishing powder to be well mixed；
2nd, 200-220 DEG C is heated, 30-40 minutes is kneaded to mediating uniformly with mixing kneader, Magnaglo is wrapped
Treatment is covered, the composite powder of greater particle size is tentatively manufactured into；
3rd, plasticizer is added, continues to knead 30-40 minutes afterwards；
4th, the composite powder crushing pulverizer that will be kneaded be ground to wherein 95% above section granularity reach 250 μm-
The composite powder of 2500 μm of relatively small particle；
5th, sub-sieve is carried out with vibratory sieve to go out less than the 2500 μm composite powder finished products of granularity and then pack.
Preferably, its Magnaglo can be the magnetic material of iron, cobalt, nickel or iron, cobalt, nickel, the compound of rubidium or oxide
Or permeability magnetic material.
Preferably, its polishing powder is the media with grinding effect such as silica, aluminum oxide, zirconium oxide.
The beneficial effects of the present invention are possessing outside magnetic conductive material or magnetic material, utilizing works plastics are to magnetic conductivity material
Material or magnetic material carry out mixing cladding, it is obtained certain protection and lifting magnetic powder life-span, outer right possessing removal force
Workpiece further reduces scuffing, and manufacture itself needs to be crushed again by kneading, the particle diameter of finished breaking is reached adjustable particle
Spend and then can reach and degree of conformity is high to be required to workpiece polishing, and carrying magnetic polishing composite powder overcomes more for recuperability
Many defects of conventional magnetic powder.
