Description
Technical field
The present invention relates to household electrical appliances and manufacture field, the preparation method being specifically related to a kind of infrared electrothermal film.
Background technology
It is little that the method that traditional employing resistance wire is heated warming oneself also exists electric heating area, and electrothermal efficiency is low, and resistance wire uses easy oxidation for a long time, the shortcoming that the life-span is short.Therefore, increasing Electric radiant Heating Film initially enters the visual field of people.
Electrothermal semiconductor membrane technology is a kind of electric-heating technology, and this technology can widely use under all use temperature working condition below 500 DEG C in the fields such as industry, agricultural, military affairs, household electrical appliances, and it can adopt various the heat forms such as tabular, tubulose.Electrothermal semiconductor membrane technology, it is just carried out theoretical research from the forties by the state such as American-European, Japanese, but not yet occurs the more ripe Electric radiant Heating Film original paper that can really be applied to some product so far.Domestic start to occur in that a collection of patent about electrothermal film technology and element one by one from late nineteen eighties, but due to problems such as the imperfection of formula and the not science of processing technology all exist power instability, attenuation big (more than 30%), operating temperature range little (within 240 DEG C).
Inorganic SnO2The hardness of Electric radiant Heating Film own is high, is combined jail with carrier, has stable high-temperature performance, can work under the higher temperature of 500 DEG C, there are good non-oxidizability, a chemical attack ability, and a resistance stability preferably, and there is the key properties such as energy-conservation, light and handy, long-lived, the flames of anger, starting current are little.Its very thin thickness, generally in micron (one thousandth of a millimeter), unique distinction is the transparency, it is seen that light transmission rate is up to more than 90%.
Graphene (Graphene) was caused the extensive concern of scientist by professor's report such as Geim of Univ Manchester UK with its peculiar performance from 2004 and great interest is predicted probably causes revolutionary variation in a lot of fields.Single-layer graphene with two dimensional crystal structure exist thickness 01334nm it be construct other dimension carbonaceous material elementary cell it can wrap up the fullerene forming zero dimension and roll and form one-dimensional carbon nanotube layer layer stack and amass and form three-dimensional graphite.Graphene is that a kind of quasiconductor not having energy gap has the carrier mobility (2 × 10cm/v) of high 100 times than silicon and at room temperature has a micron order free path and big coherence length therefore Graphene is the ideal material of nanometric circuit.Graphene has the specific surface area (2630m/g) of good heat conductivity [3000W/ (m K)], high intensity (110GPa) and super large.The performance of these excellences makes Graphene have the application prospect of light in fields such as nano electron device, gas sensor, energy storage and composites.
Summary of the invention
The preparation method that the present invention provides a kind of infrared electrothermal film, infrared electrothermal film prepared by the method, there is the electric conversion of excellence and longer service life.
To achieve these goals, it is achieved above-mentioned purpose, the preparation method that the invention provides a kind of infrared electrothermal film, this infrared electrothermal film includes substrate, the first Electric radiant Heating Film and the second Electric radiant Heating Film；
The method comprises the steps:
(1) the first electric membranous layer slurry is prepared
Weigh the graphene powder of 6-7 weight portion, the far infrared transmission agent of 0.5-2 weight portion, the bonding diluent of 3-5 weight portion, stir after first graphene powder being mixed with far infrared transmission agent, after being subsequently adding bonding mixing diluents, form slurry；Described bonding diluent is resistant to elevated temperatures phenolic resin, and the particle diameter of graphene powder is: 30-60nm；
(2) the first Electric radiant Heating Film is formed
Slurry being coated uniformly on substrate surface and forms film, dry or form the first Electric radiant Heating Film after drying, wherein the THICKNESS CONTROL of the first Electric radiant Heating Film is at 5-15 μm；
(3) the second Electric radiant Heating Film slurry is prepared
By SnCl4.5H2O, ethanol, HF, H3PO4With deionized water according to mass ratio 50-65:12-20:4-6:5-8:25-35 mix and blend, obtaining stirring mixed liquor, wherein mixing time is 3-5h；
Reflux 1-2h by stirring mixed liquor in the return duct of 70-90 DEG C；
By the mixed liquor ageing 6-8h after backflow, obtain the second Electric radiant Heating Film slurry；
(4) the second Electric radiant Heating Film is formed
Being coated in the second Electric radiant Heating Film by the second Electric radiant Heating Film, sinter 0.5-1h at 550-650 DEG C, form the second Electric radiant Heating Film, wherein the THICKNESS CONTROL of the second Electric radiant Heating Film is at 5-10 μm.
The advantage that infrared electrothermal film prepared by the present invention combines Graphene Electric radiant Heating Film and semiconductor thermoelectric film, small electric current just can activate Graphene far-infrared electric part, than traditional electrothermal method saving energy 60%, improve the utilization rate of electric energy, the semiconductor thermoelectric film heat transfer resistance adopting above-mentioned material and proportioning is little, during electrified regulation, heat can quickly pass to heated object, and owing to this mode of heating heat conductivity is good, so far-infrared electrothermal film self-temperature is very not high, not having rubescent, heating phenomenon produces, and radiation heat loss is only small.
