Problems solved by technology

[0002] The surface treatment process of permanent magnet ferrite devices currently includes: electroplating, baking varnish, plastic spraying, etc. These processes have good effects on good conductor materials, but the process treatment effect on permanent magnet ferrite, which is a poor conductor material, is very poor. So that its scope of use and effect of use have not been brought into full play
And there is no process for firing pottery, blue and white, pastel and firing glaze on the surface of permanent magnet ferrite devices at present

Embodiment 1

[0015] 1. In the production process of ferrite devices, 94 kg of ferric oxide, the raw material of permanent magnet ferrite, is used as the main raw material, mixed with 6 kg of polyvinyl alcohol as the binder, and the weight percentage of ferric oxide and polyvinyl alcohol is mixed It is 94% of ferric oxide and 6% of polyvinyl alcohol. The magnetic material blank is pressed on the hydraulic press through the mold, and then sintered at 1100°C for 12 hours, and then cooled with the furnace for 12 hours to make a semi-finished product; Fine grinding is made into permanent magnet ferrite devices.

[0016] 2. The surface of the finished permanent magnet ferrite is coated with ceramic material, and sintered at a high temperature of 1000°C to permanently bond the ceramic material on the surface of the device.

[0017] 3. Coat the surface of the ceramic layer of the permanent magnet ferrite device with blue and white materials and pastel materials, burn them at a temperature of 700°C...

Abstract

The present invention relates to composite material product of permanent magnetic ferrite material and ceramic material and its production process. The composite material product features its ceramic material layer, blue-and-white porcelain layer, familla-rose porcelain layer and glaze material layer sintered on the surface of the permanent magnetic ferrite. The production process includes the following steps: 1. mixing the material for permanent magnetic ferrite including Fe2O3 and adhesive PVA, pressing to form and high temperature sintering to obtain semi-finished permanent magnetic ferrite device; 2. coating ceramic material to the surface and high temperature sintering to combine the ceramic material onto the device; 3. coating blue-and-white porcelain material and familla-rose porcelain material and high temperature sintering; and 4. coating glaze material and high temperature sintering on the surface of the device.

Description

technical field [0001] The composite material product of permanent magnet ferrite material and ceramic material and the manufacturing process thereof of the present invention relate to a method of firing ceramic material, glaze material, blue and white material, pastel material on the surface of permanent magnet ferrite device and its manufacturing process The composite material product, the process and the composite material product belong to the technical field of magnetic materials and ceramics. Background technique [0002] The surface treatment process of permanent magnet ferrite devices currently includes: electroplating, baking varnish, plastic spraying, etc. These processes have good effects on good conductor materials, but the process treatment effect on permanent magnet ferrite, which is a poor conductor material, is very poor. Make its scope of use and use effect not obtain bigger play. And also do not have the technological method of firing pottery, blue and whi...
