Embodiment

[0036] Production Method:

[0037] 1. First stamp the aluminum material with a thickness of 1.5~1.8mm into the pot body through the mold, then sandblast the outer surface of the pot body to make the surface roughness Ra 2.0~6.0μm, and then carry out oxidation treatment on the surface .

[0038] 2. Spray the magnetic material with strong magnetic permeability on the outside of the pot body, and the spraying atomization pressure is 0.2-0.3MPa. Secondly, it is baked for 15 minutes at a temperature of 80-90 degrees Celsius to form a magnetically permeable layer with a film thickness of 40-200 μm.

[0039] The components of the magnetically permeable material are: 20-30 parts by weight of resin, 30-65 parts by weight of magnetically conductive metal pigment, and 1-5 parts by weight of additive organic matter. Among them, the magnetic metal pigments are mainly iron-aluminum alloys, nickel-iron alloys, silver alloys or amorphous soft magnetic alloys and other magnetic metal pigment...

Description

technical field [0001] The present invention relates to the field of materials. Specifically, the present invention relates to a magnetic pot and a preparation method thereof. Background technique [0002] With the gradual popularization of electromagnetic heating technology, the use of electromagnetic heating technology in electric pressure cookers and rice cookers will also become a trend. However, at present, the inner pots of electric pressure cookers and electric rice cookers are mostly made of aluminum or stainless steel composite materials. Aluminum pots are low in cost and simple in production process, but aluminum is not magnetically conductive, so electromagnetic heating cannot be used. Although the stainless steel composite pot can use electromagnetic heating, the production process is complicated, the yield rate is low, and the cost is high. Contents of the invention [0003] The present invention aims at solving one of the above technical problems at least ...
