Abstract
Conducting phase material and glass phase material in certain proportion are mixed and added with organic solvent to result in thick film pulp, which is painted onto alumina substrate to form thick film resistor through high-temperature sintering. The conducting phase consists of Si, Mo, Mg, C, Ti, Ca, Fe, Ba, etc.; the glass phase is lead-less glass; the ratio of conducting phase to glass phase is 30-80 to 20-70; the sintering temperature is 800-1350 deg.c; and the substrate material is alumina ceramic or quartz glass. The present invention has the advantages of high heating temperature, wide working voltage range, no toxicity, no pollution, high electricity-to-heat conversion efficiency, firm film layer and long service life.
Description
Thick-film electronic material and electric-heating technology field under the present invention.
Thick-film electronic material and technology are widely used in the prior art, are mainly used in Thick ﹠ Thin Film Integrated Circuit technology and the electronics chip components and parts technology.These thick-film materials mainly are used as conductor and resistance, appearance element, carry out information processing, do not have electric heating function.The Heating element that electric-heating technology uses on the field such as household electrical appliance and worker, farming, doctor, scientific research for a long time is nichrome wire or electrothermal tube mostly, traditional resistance wire has heating efficiency low, life-span short (as electric iron), can not be in shortcomings such as work under the low voltage (as 12V).The Heating element of the replacement electrothermal tube that grows up the seventies has PTC ceramic plate or film-type Electric radiant Heating Film and non-metallic heating element, and they use power-frequency voltage, and heating temp is no more than 300 degrees centigrade.Can partly replace electrothermal tube, be applied to electric chafing dish, electric cooker is on about 200～300 degrees centigrade product of heating temps such as warm-air drier.But the above-mentioned materials heating temp is lower, and (as the PTC ceramic plate) that have has Lead contamination, and shortcoming such as can not work under no-load condition has limited their application.
The objective of the invention is to invent a kind of its heating temp maximum and can reach 700 degrees centigrade, operating voltage can be at safety voltage or 110V such as 12V, 24V, 36V, the thick film high temperature exothermic material that the 220V power-frequency voltage uses down.
The said thick film high temperature exothermic material of the present invention adopts thick-film electronic material and technology, manufactures the exothermic material with electric heating function.Conductive paste material is mixed by suitable proportion with the glassy phase material, add organic solvent and form thick film ink, be coated on the matrix such as aluminum oxide, behind high temperature sintering, form thick-film resistor.
The conductive phase of thick film ink is made up of silicon (Si), molybdenum (Mo), manganese (Mn), carbon (C), titanium (Ti), calcium (Ca), iron (Fe), barium simple substance elements such as (Ba) or their oxide compound; Glassy phase is made of lead-less glasses material.
The weight ratio proportioning of conductive phase and glassy phase is: conductive phase: glassy phase=30～80: 70～20;
Sintering temperature is: 800～1350 degrees centigrade;
Body material is: 45%～99% alumina ceramics or silica glass, base shape can be flat board or tubulose;
Its side's resistive scope be 5 Europe/sides (megaohm/side of Ω/ )～5 (and M Ω/), as required, apply rated operational voltage after, heating temp is from room temperature to 700 degree centigrade.
The present invention has following effect:
(1) heating temp is from room temperature to 700 degree centigrade.
(2) the side resistance of thick-film material from 5 Europe/sides～5 megaohm/sides.
(3) low-resistance material can use low-work voltage (12V, 24V, 36V), highly resistant material use power-frequency voltage (110V, 220V) etc.
(4) not leaded and other toxic substance of starting material, non-environmental-pollution.And leaded in the ptc material, pollution is arranged.
(5) this material has high infrared energy and high electricity-thermal radiation efficiency of conversion.
(6) satisfy the demand for heat (as noninductive electric iron) of noninductive occasion.
(7) life-span is long.
(8) film and matrix bond are very firm, cold-resistant thermal shock resistance properties good (from room temperature to 700 degree centigrade cold cycling repeatedly, rete do not have burst and obscission)
The said organic solvent of the present invention can be following ingredients: Viscotrol C, ricinolic acid calcium, ricinolic acid barium, staybelite, ethanol, Terpineol 350, propyl carbinol, polypropylene glycol, ethyl cellulose, Nitrocellulose, Yelkin TTS, Semen Lini oil, butyl carbitol amyl acetate, butylcarbitol etc.
