Description
It is relevant with coating technology to the invention belongs to electrothermal film technology ， And.
The electric heating body of the employed electric heating appliance of people so far, generally there are following two kinds: (1) metal electric heating silk, the metal electric heating silk is that the heat efficiency is low as the technical problem underlying that electric heating body exists, and generally 40%～60%, heats inhomogeneous, metal electric heating silk self working temperature height, 800 ℃～1000 ℃, be easy to oxidation, the life-span is short, electric furnace pan, mica sheet, asbestos or the complementary material of other high-temperature insulation must be arranged, the high a series of problems of heating system cost; (2) semiconductor film membranous type Electric radiant Heating Film, this Electric radiant Heating Film generally adopt the prepared technology of spray pyrolysis, need to use special equipment, complex manufacturing technology need be operated under 550 ℃ of high temperature, and energy consumption is big, the cost height, the material to ground also has certain limitation simultaneously, therefore is not easy to apply.For addressing the above problem, the paint-type electric heating film that the present invention proposes a kind of novelty is as electric heating body.Electric radiant Heating Film can directly be sprayed, brush, dip-coating form electric heating film on ground, thereby makes the heat efficiency improve 30～50%, and manufacture craft is simplified greatly, and cost reduces greatly, is convenient to promote the use of.
Main points of the present invention are that electric heating body is made up of ground, paint-type electric heating film, electrode, insulating waterproof layer more than one deck.The electric conducting material of Electric radiant Heating Film coating is superfine graphite powder (percentage by weight is 10～50%), also can mix an amount of lemel (as copper powder, nickel powder etc.), compound fine powder, or semiconductor fine powder.
Electric radiant Heating Film can directly be brushed, spraying or dip-coating be at glass, enamel, pottery, through metal material, rubber, plastics, insulation macromolecular material, glass-reinforced plastic material, glass fiber material, asbestos fibre material surface that insulation is handled.Reach required electrical heating power by controlling diaphragm thickness and membrane area, general electrical heating power density should be controlled at 0.1W/cm
2～10W/cm
2Between.On a product, can design an Electric radiant Heating Film, also can design several independently Electric radiant Heating Film, adjust electrical heating power with a change over switch.Extraction electrode can be used metal forming, as Copper Foil, nickel foil, or use wire netting, as copper mesh, nickel screen, and metal wire, as copper cash, nickel wire etc., also can use Alloy Foil, alloy wire, alloy network is direct and Electric radiant Heating Film is bonding, also can use metal, the solid block electrode that alloy or graphite are made, adopt the press contacts mode directly to contact with Electric radiant Heating Film, also can use conducting resinl, as cupric powder conductive adhesive, the nickel powder conducting resinl, sliver-powder conducting glue, the graphite powder conducting resinl, conductive compound fine powder conducting resinl, semiconductor fine powder conducting resinl, or the conductive emulsion of corresponding electric conducting material and electrically-conducting paint are as the bonding electrode of binding agent or directly as conductive electrode.The bonding of electrode and ground can also be used organic adhesion agent, as phenolic aldehyde, Lauxite class adhesive, epoxy resin tackifier, polyamine lipid adhesive, epoxy resin tackifier, polyamine lipid adhesive, the esters of acrylic acid adhesive, the polyamide-based adhesive of polyester, organosilicon, Organic fluoride class adhesive, polyimides adhesive, Ju Ben And imidazoles adhesive; Can use inorganic adhesive, as the aluminium oxide adhesive, cupric oxide adhesive, alumino-silicate adhesive, silicate adhesive, silicon oxide compound adhesive etc.
Can brush at the Electric radiant Heating Film outer surface, spraying or dip-coating insulation watertight composition, the step of spouting is improved the security reliability of Electric radiant Heating Film.General employed coating has amido insulating varnish, epoxy insulation varnish, phenolic aldehyde insulation varnish, diphenyl ether insulating varnish, polyimide insulative lacquer, polyester alkyd neulating varnish, organic silicon insulating varnish, Organic fluoride insulating varnish and the above-mentioned insulating varnish insulating varnish of mixed preparing in all proportions.Insulating waterproof layer can play decoration, insulation, insulation, waterproof action to Electric radiant Heating Film.Can add the proper insulating oxidate powder in the coating, as alumina powder, titanium oxide powder etc.As ground is the spout insulation processing of capable ground of the also available said method of metal material.
Preparation technology is simple for the Electric radiant Heating Film goods, can glue electrode earlier and coat Electric radiant Heating Film and insulating waterproof layer again, or coat the sticking again electrode of Electric radiant Heating Film earlier and be coated with insulating waterproof layer again.
The technology for preparing electrode that the present invention introduced is equally applicable to the tin oxide Electric radiant Heating Film, indium oxide Electric radiant Heating Film, indium tin oxide Electric radiant Heating Film and other various types of Electric radiant Heating Film.
Electric radiant Heating Film goods application is extensive, can ground be processed into arbitrary shape according to different needs, as curved surface, plane or the like; Can be processed into electric heating utensil, as electric cup, electric-heating thermos, electric heating scuttlebutt, electric chafing dish, electric cooker, electric heating basin, electric heating mess tin, electric coffee pot or the like; Also can be processed into electric heating appliance, as electric heating shower, electric heater, electric calorifier, Electric hand stove, Electric foot warmer, electric heating bed, electrothermostat, electric iron, electric heating medical apparatus etc.; Also can be processed into electric heating element, as electric-heating thin film band, electric heating piece, electric hot plate, electrothermal tube or the like.
The present invention compared with prior art, it is clear to have principle, simple in structure, with low cost, heat is imitated high, of many usesly advantage such as is easy to apply.The low temperature drying that can be used for industries such as medical treatment, food, timber processing, papermaking, weaving, printing and dyeing can be used for the insulation, antifreeze of various pipelines, storage tank, can be used for the insulation heating of building trade, can be used for the frost prevention of transportation and communication glass pane.Above-mentioned good effect is that prior art is incomparable.
