Abstract
The invention discloses a fiber ceramic with electric field intensity. The technology scheme is that: rubbing the ceramic base material to 100-300 item, adding 3-10% carbon fiber or metal fiber, adding 30-300% iron dust, whisking equal, extruding, drying, and roller kiln sintering. It could be used in the electromagnetic screen and static electricity proofing field.
Description
One, technical field: electromagnetic shielding (antistatic) fiber porcelain plate and preparation method belong to building electromagnetic shielding field.Specifically be fiber porcelain plate and the preparation method who utilizes metallic fiber and carbon fiber to make with electric-field intensity.
Two, technical background: itself does not possess electric-field intensity common ceramic materials, is the good insulation performance material.The present invention makes ceramic board have electric-field intensity, makes ceramic board promptly have decoration functions and has possessed electromagnetic shielding and anti-static electrification again.Needing can be used for electromagnetic shielding and antistatic field.
Three, summary of the invention: purpose of the present invention is exactly to existing ceramic wafer, provides a kind of in ceramic preparation process, fills metallic fiber or carbon fibre material and iron powder, increases the technology of preparing of porcelain plate electric-field intensity.The technical scheme that adopts is: it is even that ceramic base-material clay 30-55%, feldspar 30-50% and quartzy 0-20% are added the water agitation grinding, fineness reaches the 30-500 order, add ceramic base-material again and do not add water agitation grinding carbon fiber or the metallic fiber of weight ratio 3-10% before, add ceramic base-material and do not add the water stirring iron powder of weight ratio 30-300% before, once more agitation grinding evenly after, extrusion modling, dry, form by a firing.Adopt the fiber ceramics plate of this technology preparation to possess electric-field intensity, electromagnetic wave is had function of shielding also can play anti-static electrification.Experiment shows, utilizes electromagnetic shielding (antistatic) the fiber porcelain plate of this technology preparation that frequency 30 (MHz)-1200 (MHz) shield effectiveness is reached 30 (dB)-10 (dB) attenuations 95%)-70%.
Four, description of drawings: do not have
Five, specific implementation method: it is even that ceramic wafer base-material clay 50%, feldspar 40%, quartzy 10% are added the water agitation grinding, fineness reaches 300 orders, adding above ceramic wafer base-material weight ratio (not adding water weight before) 5% carbon fiber and 200% iron powder stirs, extrusion modling, oven dry, roller kilns are disposable burns till, 900 ℃-1300 ℃ of firing temperatures, firing period 30-200 minute.
Claims (5)
1, electromagnetic shielding (antistatic) fiber porcelain plate is characterized in that in the porcelain plate manufacturing process, adds carbon fiber or metallic fiber in the porcelain plate base-material, adds iron powder, makes porcelain plate possess electric-field intensity.
2, according to claims 1 described electromagnetic shielding (antistatic) fiber porcelain plate manufacturing technology, fiber porcelain plate base-material adds the carbon fiber of 3-10%.
