A kind of component concentration of electric-heating coatings, as follows by weight: carbon dust 30-95 part (acetylene black or Graphite Powder 99), shellac 2-25 part, thinner 50-300 part.To compare cost low with existing electric-heating coatings, and component is simple, and Heat stability is good, life-span are long, and electrothermal efficiency improves 10%-15%, is particularly suitable for the brushing wall, replaces radiator or electric heater to use as a kind of new-type electric heating element.
Description
The invention provides a kind of electric-heating coatings, is electrical conductor with the carbon dust in this coating.Belong to the electroheat technology in the electricity.
The electric-heating coatings technology has been widely used in Electric heating household utensil, electrical heated appliance and an electric heating element.Because thermo-efficiency can improve 30-50%, is well received.CN86100500A discloses a kind of coating type electric heating element and technology.Its invention main points are that electric heating body is made up of ground, paint-type electric heating film, electrode, insulating waterproof layer more than one deck.The electro-conductive material of Electric radiant Heating Film coating is superfine graphite powder (weight percent is 10-50%), also can mix an amount of lemel (as copper powder, nickel powder etc.), compound fine powder, or semi-conductor fine powder.Electric radiant Heating Film can directly be brushed, spraying or dip-coating be at glass, enamel, pottery, through metallic substance, rubber, plastics, insulation macromolecular material, glass-reinforced plastic material, glass fiber material, the asbestos fibre material surface that insulation is handled.Reach required electrical heating power by controlling diaphragm thickness and membrane area.Weak point then is that cost is higher, and electro-conductive material disperses to be difficult to evenly, in order to obtain better quality, still need add a certain amount of metal powder.And require to use the superfine graphite powder, component is complicated, and difficulty of construction is big.
Above-mentioned deficiency at existing electric-heating coatings technology, more advantages of simple, cost can reduce significantly to the purpose of this invention is to provide a kind of component, but application surface is more extensive, particularly can be below 36 volts in low pressure, it is works better under the safety voltage, to ground attached no particular requirement, electrothermal efficiency further improves and is particularly suitable for the electric-heating coatings that big area heating needs.
The objective of the invention is to realize by following technical measures.
Make electro-conductive material (acetylene black, carbon black, Graphite Powder 99, it is meticulous that the granularity of Graphite Powder 99 does not need) maximum particle diameter with carbon dust and get final product below 25 microns, make dispersion, the jointing compound of carbon dust with flake lac.
The dilution earlier of dispersion, jointing compound, and then drop into the carbon dust mixing.
The component concentration of electric-heating coatings, as follows by weight:
Carbon dust 30-95 part (acetylene black or Graphite Powder 99)
Flake lac 2-25 part
Thinner 50-300 part
With the coating that has all mixed by the said ratio component, brushing also can directly be coated on the wall at the utensil of the need heating that performs insulation processing.Coat-thickness and area can be selected according to required thermal value, and voltage of supply is selected through simple experiment.
Extraction electrode can be used tinsel, 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, direct and the coated adhesive of alloy network, also can use metal, the solid block electrode that alloy or graphite are made, adopt the press contacts mode directly to contact with coating, also can use conductive resin, as cupric powder conductive adhesive, the nickel powder conductive resin, sliver-powder conducting glue, the Graphite Powder 99 conductive resin, conductive compound fine powder conductive resin, semi-conductor fine powder conductive resin, or the conductive emulsion of corresponding electro-conductive material and electrically conducting coating are as the bonding electrode of binding agent or directly as conductive electrode.
Electric-heating coatings provided by the present invention, because being carbon dust, dispersion, binding agent, electro-conductive material is flake lac at a low price again, therefore, to compare cost low with existing electric-heating coatings, component is simple, and Heat stability is good, life-span are long, and electrothermal efficiency improves 10%-15%, be particularly suitable for the brushing wall, replace radiator or electric heater to use as a kind of new-type electric heating element.
The technical characterictic that the invention is further illustrated by the following examples:
1,30 parts of carbon dusts (acetylene black, Graphite Powder 99 etc.)
2 parts of flake lacs
60 parts of ethanol (industrial)
The gained electric-heating coatings can be used as the electric heating device of cooker.
2, carbon dust is 40 parts
5 parts of flake lacs
100 parts of industrial alcohols
The gained electric-heating coatings, suitable especially brushing replaces heating supply on the wall.
3, carbon dust is 95 parts
20 parts of flake lacs
200 parts of industrial alcohols
The gained electric-heating coatings can be made the electric heating device of electric heating bed.
