Embodiment 1

[0031] A magnetic polishing liquid suitable for die-casting aluminum alloy materials is composed of the following components: 40g of NdFeB magnetic powder, 40g of diamond micropowder, 300g of corn oil, 8g of graphite powder, and 12g of diatomaceous earth.

Embodiment 2

[0033] Such as figure 1 As shown, the preparation method of the magnetic polishing liquid suitable for die-casting aluminum alloy materials in embodiment one is as follows:

[0034] Step 1. The NdFeB magnet with a weight of 100g is fragmented, and the fragments screened through the 5mm sieve are put into the mixer for atomization and wetting treatment; after atomization and wetting The broken pieces are put into the ball pressing machine for pressing, and the wetted NdFeB magnetic block balls formed are put into the heating furnace for drying, then cooled, and then put into the roller press for crushing, and then ball milled (ball milled by a ball mill), drying and Ball milling again to obtain NdFeB magnetic powder with a particle size of 5 μm;

[0035] Step 2. Take 40g of NdFeB magnetic powder, add 40g of diamond powder into the NdFeB magnetic powder gradually in 3 times, and mix manually for 20 minutes after each addition of diamond powder; after adding all 40g of diamond p...

Abstract

The invention discloses a magnetic polishing liquid suitable for die-casting aluminum alloy materials and a preparation method thereof. Magnetic fluid polishing liquid is the key technology of magnetic fluid polishing. The magnetic polishing liquid of the present invention is composed of the following components in mass percentage: 10% of NdFeB magnetic powder, 10% of superhard abrasive micropowder, 75% of base liquid, 2% of thixotropic agent, and 3% of anti-precipitation agent. The NdFeB magnetic particles in the present invention have high magnetic properties, can better wrap and drive superhard abrasives, and improve polishing efficiency, and due to the addition of base liquid and anti-sedimentation agent, the combination can be finished under the action of magnetic fine powder The group becomes a flexible body, and the combined body can change the rigidity of the flexible body under the control of an external magnet to realize controllable polishing force.

Description

technical field [0001] The invention belongs to the technical field of polishing, in particular to a magnetic polishing liquid suitable for die-casting aluminum alloy materials and a preparation method. Background technique [0002] Among automotive lightweight materials, the comprehensive cost performance of aluminum alloy materials is higher than that of steel, magnesium, plastics and composite materials. It has advantages in terms of application technology, operational safety and recycling. However, the various mechanical processes of aluminum alloy high-precision surface workpieces, from cold working to hot working, will almost inevitably leave defects on the surface of the parts, such as surface bumps, flashes, obvious convex edges, microscopic cracks and burrs, etc. . In order to eliminate the surface defects left by processing on the surface of parts, it is necessary to carry out polishing of parts. [0003] Choosing a suitable polishing method and polishing process...
