Description

A kind of high-efficiency electric-heating film of anti-electric wall

Technical field

The utility model relates to a kind of electro-heat equipment, the Electric radiant Heating Film during especially electric floor heating or electric wall are warm.

Background technology

The Electric radiant Heating Film of being processed by exothermic materials such as electrically conductive inks (can be made into rigid electric hotting mask and flexible electrothermal membrane) is mainly adopted in conventional electric floor heating.But when being laid on mattess, can be excessive because of leakage current, and (earth leakage protective device tripping operation) phenomenon that trips can not be installed on the mattess (or floor tile, marble ground) and uses so Electric radiant Heating Film is done floor heating.It is insurmountable chronic disease in the industry all the time.If on the Electric radiant Heating Film floor heating circuit earth leakage protective device is not installed,, be a great hidden danger for personal safety though solved the problem of tripping operation; In case the generation electric shock accidents will cause serious consequence.The little electromagnetic radiation of the certain dimension of promising generation in heating process.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that above-mentioned background technology exists, and a kind of high-efficiency electric-heating film of anti-electric wall is provided, and that this Electric radiant Heating Film should have is safe and reliable, make characteristics simply and easily.

The technical scheme that the utility model provides is: a kind of high-efficiency electric-heating film of anti-electric wall comprises the basement membrane that can curl; Said Electric radiant Heating Film comprises and being produced on the basement membrane and the conductive heating layer through wire connecting power, and first inner insulating layer and second inner insulating layer that is compounded in the conductive heating layer lower surface that are compounded in the conductive heating layer upper surface; The upper surface that it is characterized in that said first inner insulating layer also from bottom to top coats the first anticreep layer and first external insulation layer successively, and the lower surface of said second inner insulating layer also from top to bottom coats the second anticreep layer and second external insulation layer successively; The said first anticreep layer and the second anticreep layer are the conductive layers that adopts typography or coating processes to process; Adopt a kind of non-metallic conducting material in graphite, carbon black, carbon crystalline substance, electrically conductive ink, conductive carbon paste, silver-colored slurry, carbon fiber paper, the carbon fiber wire, said basement membrane, first inner insulating layer, second inner insulating layer, first external insulation layer and second external insulation layer are the flexible plastic film layer.

The said first anticreep layer and the second anticreep layer are also respectively through the zero line in the wire connected power.

Said flexible plastic film layer is that PET or PPT or POF or ABS or PP plastics are processed.

The operation principle of the utility model is: the conductive heating layer energising back evolution of heat and far infrared carry out radiant heating; The charge inducing that produces in addition imports zero line by anticreep layer and can't gather; So induced voltage also is eliminated; Leaky also promptly disappears, and does not also have external electromagnetic radiation.

The beneficial effect of the utility model is: because the utility model has been eliminated leakage current, induced voltage, electromagnetic radiation phenomenon (function with anti-electric wall) fully, thereby guaranteed safe and reliable; And; Each inner insulating layer and each external insulation layer all adopt various plastic films such as PET, PPT, POF, ABS, PP; Made flexible electrothermal membrane can curl bending (therewith the contrast; The rigid electric hotting mask that adopts various plastic plates or epoxy resin PP the to process bending of to curl), not only helps serialization large-scale production, also have the characteristics of convenient transportation.In addition, the change of being done is also comparatively simple, so cost of manufacture can further reduce.Add the high thermal efficiency and control characteristic of simple of Electric radiant Heating Film, application prospect is more wide.

Embodiment

The anti-creeping high-efficiency electric-heating film that curls that the utility model comprises, electrically conductive ink that conductive heating layer adopts wherein (be called conductive carbon paste again, or silver slurry, carbon fiber paper etc.), be a kind of crystal structure of graphitic carbon element.Electrically conductive ink and far infrared cast charge are mixed into electrocondution slurry, through printing or being coated on the basement membrane (basement membrane is a flexible plastic film usually), through just becoming conductive heating layer behind the hot setting; After the conductive heating layer two ends connect Copper Foil lead 9 respectively, can heating power.The electric conversion rate of conductive heating layer is up to more than 99.8%.

In the electric floor heating Electric radiant Heating Film that the utility model provides, in the middle of the conductive heating layer of connection power supply was positioned at, the tow sides of heating layer are compound inner insulating layer (i.e. first inner insulating layer 4 and second inner insulating layer 6) respectively; The upper surface of first inner insulating layer is a superficial layer 1.

Above structure is all identical with existing electric floor heating Electric radiant Heating Film.

The utility model is on the outer surface of inner insulating layer (first inner insulating layer 4 and second inner insulating layer 6), also to coat anticreep layer (induced electricity layer) and an external insulation layer from inside to outside successively to the improvement of described Electric radiant Heating Film; Wherein, between the inner insulating layer 4 and superficial layer 1 of heating film positive (one side up), from bottom to top coat first anticreep layer 3 and first external insulation layer 2 successively; Below the inner insulating layer 6 of heating film reverse side (one side down), from top to bottom coat second anticreep layer 7 (the induced electricity layer) and second external insulation layer 8 successively.

The carbon crystalline substance conductive layer (dried carbonaceous conductive slurry) that the said first anticreep layer, the second anticreep layer be preferred to adopt typography such as graphite, electrically conductive ink, conductive carbon paste, silver slurry or coating processes to form; And these two anticreep layers are also respectively through the zero line in the wire connected power; Go up the induced voltage that produces to eliminate anticreep layer; Make the also non-inductive electric current of concrete layer (ground floor) (leakage current) on the Electric radiant Heating Film external insulation layer produce, the earth leakage protective device that is beneficial to dispose in the floor heating circuit normally moves.

The described electric floor heating of the utility model is below second external insulation layer of above-mentioned Electric radiant Heating Film, from top to bottom to set gradually reflector (adopting aluminium foil usually) and heat-insulation layer (adopting polyurethane foam material usually).Said Electric radiant Heating Film is layed in mattess ground order (from bottom to top); Ground floor is heat-insulation layer, second layer reflector, the 3rd layer of Electric radiant Heating Film (conductive exothermal film), concrete layer, ground surface layer; It is neat on the ground superimposed to press the level tiling; (Electric radiant Heating Film is that web-like length has hundreds of rice, and the length size arbitrarily cuts on demand).

Obviously, owing to set up first anticreep the layer 3 and second anticreep layer 7, and all connect zero line.So the electric charge that produces during heating film energising work is constantly drawn and can't be gathered by zero line, so induced voltage can't be set up, leaky does not promptly exist, and electromagnetic wave also is that (shielding) disappears.
