Description
Technical field
The present invention is relevant for a kind of soft electric heating device, particularly relevant for a kind of high-effect soft electric heating device of being made up of soft heater and high heat conductive insulating layer that includes, so that the demand of heating to be provided.It is a kind of in order to make the manufacture method of this high-effect soft electric heating device that the present invention also provides.
Background technology
The mankind are required in response to industry or life, often need on object, heat, general calandria (sheet) can be divided into rigid or soft two big classes, the former as masses' electrothermal furnace known, electric blanket that the latter is then commonly used just like automobile de-fog, winter or the like.
On the practice, therefore soft electric heating device hereinafter also is called " soft electric heating piece " often in the form of sheets, on using its special convenience is arranged, and removes the application aware that changes in the past, has more crossed over standard and the bottleneck of script to heating.Making with regard to the employed insulating material with regard to soft electric heating device, mainly can be divided into silica gel (Silicone), polyimides (Polyimide Film, PI), polyester (PET) three major types.With silica gel is example, its characteristics include: (1) silica gel heating plate can replace the common metal heater, normally be made into the plane calandria of soft thin (standard thickness 1.5mm), flexibility is good, but driving fit is attached at various curved surfaces, even be irregularly shaped or the heating object surface of round cylinder slot shape, normally make with the model normalization according to process technique with nickel alloy resistance line, stable and durable in the application; (2) silica gel has unexistent thermal endurance of other organic rubbers (its temperature range that is suitable for is for-60 ℃ to+250 ℃) and electric insulating quality, so but semipermanent is used in application of temperature below 200 ℃ continuously, be applicable to that each industry is widely used in the spare part or the equipment of machine, comprise applicable to each given voltage, as 12V, 100V, 200/220V or 440V etc.
Though the silica-gel electrothermic sheet has above-mentioned multiple advantages, but it also has some shortcomings, comprise: (1) is easy to local overheating: the silica-gel electrothermic sheet is made up of two silica gel up and down, general organic materials such as silica gel all belong to the non-conductor of heat, so surface temperature that the temperature of its inner calandria will be required far above the outside, cause near the silica gel local overheating of calandria easily, even burn out carbonization, produce risk of short-circuits; (2) tackness of silica gel is relatively poor: often need electric heating piece is followed on to be heated with adhesive agent on using, but the chemical property of silica gel can cause the situation of sticking together poor effect, forms the puzzlement on using.
Except the silica-gel electrothermic sheet, PET and the soft electric heating piece of PI two classes in addition commonly used.It shown in Fig. 1 the schematic configuration diagram of the known soft electric heating piece of PET material (label 100), its production method is with heater 104, as carbon paste etc., be printed on printing type on the top side face 103 of the counterdie of manufacturing by PET 102, bottom side 107 with another teleblem of also being manufactured by PET 106 is attached on the top side face 103 of counterdie 102 again, and heater 104 is folded between the bottom side 107 of the top side face 103 of counterdie 102 and teleblem 106.Be provided with adhesive layer or glue-line 105 on the bottom side 107 of teleblem 106, can teleblem 106 being anchored on the counterdie 102 by the mode of pressing of mat is to form the protection dielectric film of heater two sides about in the of 104.The another kind of known soft electric heating piece of PET material (label 100 ') is as shown in Figure 2, wherein between the bottom side 107 of heater 104 and teleblem 106, be coated with the glue-line 105, this glue-line 105 also extends between the top side face 103 of heater 104 and counterdie 102, that is also is coated with glue-line 105 between the top side face 103 of heater 104 and counterdie 102.
Because the temperature tolerance of PET film (being teleblem 106 and counterdie 102) itself is not good, its softening point is about about 70 ℃, so this class only be can be applicable on the operational requirements of lower temperature by the made soft electric heating piece of PET material.
As for the soft electric heating piece of PI, though but PI film heatproof itself reaches 400 ℃, and employed adhesive agent was that temperature tolerance is not good when its protection insulating barrier was made, and therefore also can only operate in the temperature about 160 ℃.
Therefore, all because of the problem of its structure and material, therefore the puzzlement that can produce local overheating also reduces the fail safe that it uses to the known soft heating plate of this three class.
