Description

The manufacture method of environment protection multifunctional conducting film
Technical field
The ohmic resistance conductive film that material or material property be feature is take in the present invention, especially relates to a kind of manufacture method of environment protection type multifunctional conducting film.
Background technology
Metal conductive oxide material is the important member in semi-conductor family, and because it has good electrical property and energy-saving effect, recent decades, widely people paid close attention to.Numerous scientific and technical personnel's unremitting effort, technical progress is remarkable, and Application Areas is constantly widened, the planar electro-conductive material of film-type particularly, because its thermal response is fast, electric conversion efficiency is high, and energy-saving effect is remarkable, and in heating, be used widely in the aspects such as water-heater.
At present, conventional metal conductive oxide film mainly contains tindioxide, indium trioxide, zinc oxide and indium acid cadmium and doping system thereof.Mostly they are to adopt the muriate of respective metal to be dissolved in dehydrated alcohol, are formulated as film forming liquid, at high temperature through spray pyrolysis or other method, form metal conductive oxide film, then through the utmost point processed elementization production that gone between.Problem is the ethanolic soln of these metal chlorides, and a large amount of chlorine and the hydrogen chloride gas that in pyrolytic coating pyrolytic process, produce, cause severe contamination to atmosphere.Chlorination has rank smell, poisonous! In the air of general operation place, content must not surpass 0.001mg/ liter, and the moisture in respiratory tract is that the former is extremely unstable, and then is decomposed into oxygen and hydrogenchloride so that chlorination intense reaction generates hypochlorous acid and hydrochloric acid.Hydrogenchloride is very easily water-soluble and generate hydrochloric acid.Hydrochloric acid is one of strong acid, has extremely strong corrodibility, to skin, can cause burn, and respiratory system is had to pungency damage.
China has put into effect the rules of " environmental protection right of veto by one vote " in recent years, and importance, urgency and national great attention in China environmental protection have been described.The old road that Yu Qizou developed country " pollutes century-old improvement for 1 year ", not as beginning from myself,, does everything possible to reduce or stop and pollutes to power from source.
Summary of the invention
The object of the invention is to propose a kind of manufacture method of environment protection multifunctional conducting film, in accordance with the old maxim of " enhance agricultural production and economize expenses ", from protection of the environment, the starting material prescription that the rich inexpensive pollution of candidate is little, reaching can be cost-saving, can treat again the object of environment kindly.
Technical scheme of the present invention is following realization, a kind of manufacture method of environment protection multifunctional conducting film, and its film forming liquid formula weight ratio is:
A manufacture method for environment protection multifunctional conducting film, its processing step comprises: preparation film forming liquid, cleaned base material, pyrolysis film forming, the utmost point processed lead-in wire, impact aging, specifically:
1, preparation film forming liquid: first with acetic acid by distilled water acidifying, in case zinc salt hydrolysis; By formula, take each component again, under stirring, slowly add successively zinc acetate two water, aluminium acetate, manganese acetate four water, neutralized verdigris one water, stir to dissolving completely, build, standby.
2, cleaned base material: the hard temperature resistant substrates such as glass, pottery, silicon carbide, enamel are cleaned with tap water, wiped steam, dry, prevent dust, standby; Slim temperature resistant substrate is as mica, and mineral wool cloth etc., wipe clean with alcohol swab if desired.
3, pyrolysis masking: clean dry and comfortable base material is loaded onto to clamping apparatus, along track, push film forming stove, at 250~300 ℃, adopt ultra low volume spray (utilize special equipment and shower nozzle, make the droplet of ejection be less than 100 microns) that the atomization of film forming liquid is sprayed in stove, pass through series of chemical, generate corresponding metal conductive oxide particulate, sedimentation embeds in substrate surface lattice, and long-pending generate be take the conductive doped film that zinc oxide is principal crystalline phase.
(CH 3COO) 2Zn·2H 2O+4O 2=ZnO+4CO 2+5H 2O
2(CH 3COO) 3Al+12O 2=Al 2O 3+12CO 2+9H 2O
2(CH 3COO) 2Mn·4H 2O+9O 2=2MnO 2+8CO 2+14H 2O
(CH 3COO) 2Cu·H 2O+4O 2=CuO+4CO 2+4H 2O
CuO+MnO 2=CuMnO 3
Copper Mn oxide is good semiconductor material, is entrained in zinc oxide crystalline phase, has improved capacitive character and the stability of rete.
4, the utmost point processed lead-in wire: according to product needed, coat conductive silver paste in the appropriate location of rete, after about 100 ℃ oven dry, send in 250~300 ℃ of reduction furnaces reductase 12 0~30 minute, cause electrode to be even compact, smooth silvery white is qualified.
5, impact aging: from electrode extraction electrode line, use higher than the voltage of 1~25 times of operating voltage and take each second after interval break-make 10~20 times, logical 3~10 minutes continuously, make rete Ordering lattice, allow the product of defectiveness fully expose problem simultaneously, screen out in time, to guarantee quality product.
Advantage of the present invention: 1; reduce and pollute; kind treatment environment; the present invention adopt zinc, aluminium, manganese, copper, acetate substitute conventional metal chloride prescription; in reactor off-gas, stopped obnoxious flavour chlorine and hydrogenchloride, the substitute is oxygen, the necessary useful gases of animals and plants existence such as carbonic acid gas and aqueous vapor; to reducing, pollute, protection of the environment plays a role.2, raw material is easy to get, and low price has data introduction: " metal average content indium in the earth's crust: tin: zinc is 0.1: 40: 132ppm ", and conducting film of the present invention is to using zinc oxide to replace tindioxide and Indium sesquioxide as principal crystalline phase, with distilled water, replaces dehydrated alcohol and make solvent.With how, for few, with low-priced Dai Gui, not only raw material is easy to get, and price advantage is obvious.3, enhance agricultural production and economize expenses, reduces energy consumption, and the present invention adopts ultra low volume spray film forming, because thing is rich, does not economize, and or not because of inexpensive not thrifty, medication is not few, and effect is fast, and number of dropouts is little, meets the old maxim of " enhance agricultural production and economize expenses ".Film-forming temperature, not as good as half of prior art, greatly reduces film forming energy consumption.4, performance is various, is widely used, and that zinc oxide electro-conductive material has is optical, electrical, piezoelectricity and the characteristic such as ferroelectric.As a kind of piezoelectric, zinc oxide percentage coupling is larger, and synergistic effect, can strengthen its task performance mutually, at modern electronic technology, acousto-optic and Radio Physics molecular engineering technical elements, is widely used.Aspect photoconductive property, because its induction force is strong, response is used to optical sensor soon; The doping of aluminium has improved the light transmission of rete, electroconductibility and stability and be used to solar cell, and flat-panel monitor and heating glass etc., the doping of copper Mn oxide, has strengthened electric conductivity and the stability of rete; 90% infrared reflectance, has widened the application aspect military application and health care.As a kind of inexpensive multi-functional semiconductor material, zinc chloride conducting film and doping system thereof have wide Prospect of R & D.
