Description
Technical field
The present invention relates to a kind of building heating product, relate in particular to a kind of self temperature limiting electrical conducting polymer electric heating membrane with ground plane.
Background technology
Low-temp radiating electrothermal membrane is as building heating product, and application case is in recent years more and more.Especially be accompanied by the appearance of " low-temp radiating electrothermal membrane " (JG/T 286-2010) product standard and " ceiling panei heating with electro-thermal film system applies technical regulation " (JGJ 319-2013), and the issuing and implementation of country's " clean air action plan ", the technology application of electric heat membrane heating will be more and more extensive.Electric heat membrane heating is applied mainly taking electric floor heating as main, heater Electric radiant Heating Film is laid on to the construction technology under solid wooden compound floor or ceramic tile that is:.Be laid on ceiling with Electric radiant Heating Film and compare with body of wall, electric floor heating requires stricter for " local overheating, the electrical safety " of system.
In prior art, solve Electric radiant Heating Film local overheating and have two kinds of methods:
Method one is the one group of temperature switch of connecting on a strip electrode of Electric radiant Heating Film, and is placed on Electric radiant Heating Film, and in the time that local temperature reaches the qualifications of temperature switch, temperature switch disconnects, and Electric radiant Heating Film opens circuit.In the time that Electric radiant Heating Film surface temperature returns to temperature switch open temp, temperature switch closure, Electric radiant Heating Film energising heating.
The shortcoming of method one is: 1) each temperature switch can only be controlled certain Electric radiant Heating Film area.Large area is mated formation, and temperature switch quantity is huge; 2) temperature detect switch (TDS) be connected wire and have certain thickness, Electric radiant Heating Film is had to certain injury, even can cough up brokenly Electric radiant Heating Film, cause electric leakage; 3) temperature detect switch (TDS) has the number of times restriction of switching and natural aging phenomenon, can affect Heating System of Electric radiant Heating Film useful life; 4) heat spot produces, and whole piece Electric radiant Heating Film is that power-off is not worked, and can affect heating effect.
Method two is that inorganic non-metallic based printing ink Electric radiant Heating Film is in the time being in harmonious proportion conductive carbon paste, add a certain amount of polyvinyl compound, directly utilize the swollen shrinkage principle of heat of this compounds, regulate the inorganic conductive such as graphite or carbon black particle gap, the dizzy distribution of electronics to control its electric conductivity by temperature, the size of electric heating transfer capability reaches the object that prevents local overheating.
The shortcoming of method two is: 1) starting current is large.Certainly the starting current of limitting warm heating cable of national Specification is 6～10 times of rated current; 2) useful life is short.Dilation reaches after certain number of times (common 2000 times), loses efficacy.3) will reach the sudden change (greatly) of resistance value, need rare hydrocarbon compound ratio of doping large, Electric radiant Heating Film enlarged in thickness, affects resistivity and heat-transfer effect.Doping ratio is little, is difficult to reach resistance value sudden change (greatly) to prevent the object of local overheating.
Safety ground technology of the prior art is:
" ceiling panei heating with electro-thermal film system applies technical regulation " (JGJ 319-2013) specified that electrothermal film electric ground heating system is in the time of Electric radiant Heating Film overlying water cement mortar backfill layer, should connect PE line with wire netting and do safety ground, and not do the concrete regulation of safety ground when above covering solid wood compoiste wood floor.In reality most of house ornamentation electrothermal film electric floor heating timber floor surface-veneer engineered in, all do not do safety ground.
The shortcoming of this method is:
1) wire netting easily punctures Electric radiant Heating Film in work progress, causes electric leakage; 2) this external wire netting does the way of ground plane, almost cannot realize for the ground end structure of straight paving Electric radiant Heating Film under compoiste wood floor or carpet.And do not do safety ground, will there is electrical safety hidden danger; 3) wire netting, for a long time in cement structures, especially at the damp ground such as bathroom, toilet, can greatly reduce even and open circuit because corrosion makes electric conductivity, thereby loses the function of safety ground;
Summary of the invention
The object of this invention is to provide strong, the safe self temperature limiting electrical conducting polymer electric heating membrane with ground plane of a kind of local overheating protectiveness.
The object of the invention is to be achieved through the following technical solutions:
Self temperature limiting electrical conducting polymer electric heating membrane with ground plane of the present invention, comprise self temperature limiting electrical conducting polymer composite zone of heating, the upper surface of described self temperature limiting electrical conducting polymer composite zone of heating and lower surface seal with dielectric film thermoplastic, the conductive grid cloth of double-deck appearance tape insulation film is covered in the upper surface of the zone of heating after plastic packaging and/or lower surface hot pressing outward, described self temperature limiting electrical conducting polymer composite zone of heating is provided with metal electrode, internal layer conductive grid cloth is connected with the negative pole of described metal electrode, and outer conductive grid cloth is connected with ground wire.
As seen from the above technical solution provided by the invention, the self temperature limiting electrical conducting polymer electric heating membrane with ground plane that the embodiment of the present invention provides, taking conducting polymer as exothermic material, can be by whole electric energy energy transform into heat energies and taking far infrared radiation heat as main, have the local overheating of preventing function, Electric radiant Heating Film self is with safety ground layer.Can solve and when Electric radiant Heating Film is particularly useful for electric floor heating for building heating, avoid the local overheating phenomenon that may occur, and solve in the time of overlying water mud layer due to the problem that produces capacity effect and cause 30mA earth leakage protective device Frequent trip.
