Description
Technical field
The utility model relates to a kind of polymer electric heating membrane.
Background technology
Electric radiant Heating Film in the electric heating material that uses on the present electric heat-producing device is divided into following several kinds: a kind ofly be the metal semiconductor type, the metal semiconductor type need be used the vacuum coater, complex process, and equipment investment is big; A kind of is glass, ceramic mould, and it is the film body with certain intensity and rigidity, can only be coated on glass, pottery etc. and go up use, and insulation property are poor, and quality is crisp, and is fragile, can not push, folds, crooked, makes its range of application receive certain restriction; Also have a kind of carbon fiber type that is, make to popularize owing to cost is high to be restricted.
In addition; Vpg connection, dull and stereotyped Electric radiant Heating Film are that Electric radiant Heating Film is being covered uniformly on the insulating body material, on surfaces such as pottery, quartz glass; Adopt high temperature sintering or other method; Electric radiant Heating Film is firmly being covered on the insulating body material surface, and Electric radiant Heating Film is that same integral planar is planar, and the thickness of Electric radiant Heating Film has certain influence to resistance.When heating power, whole planar Electric radiant Heating Film is easy to the power electrode contact position and produces big overcurrent and cause that heating is too high burns electrode and reduce useful life.
Summary of the invention
The utility model provides a kind of polymer electric heating membrane to the weak point of above-mentioned existing product technology, and simple in structure, easy to process, cost is low, and is safe, applied widely, good heat dissipation effect, and the life-span is long.
To achieve these goals, the technical scheme of the utility model employing is such: a kind of polymer electric heating membrane comprises Electric radiant Heating Film matrix and insulating body; Insulating body is provided with the Electric radiant Heating Film matrix; The Electric radiant Heating Film matrix is lenticular structure, and convex portion is provided with the conductive silver paste circuit layer, and the conductive silver paste circuit layer is provided with the macromolecule heating layer; The two ends external lead wire of Electric radiant Heating Film matrix, concave portion is provided with protective layer.
As preferably: described macromolecule heating layer is a carbon slurry heating layer, and protective layer is pressure sensitive adhesive double coated.
As preferably: the two-end thickness of Electric radiant Heating Film matrix is greater than the thickness of centre, and mid portion is recessed, and two end portions is protruding.
With the existing product compared with techniques; The advantage of the utility model is: have the function that prevents because of electric current increases and heating causes fire hazard rapidly; Product is fire-retardant; Safe, product is counter-bending, anti-aging, anti tear, resistance to corrosion are strong, and the utility model all can normally use under the situation of folding 180 degree not.Its heat resistance is good, and product is indeformable in 100 ℃ of high temperature.Its cost is low, is not afraid of humidity, can be used for automobile industry rearview mirror mist elimination, and industry such as in the clothing, mattress is applied widely.Its good heat dissipation effect, its local damage can not cause short circuit, does not influence the normal heat transmission function of other part.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
With reference to Fig. 1, a kind of polymer electric heating membrane comprises Electric radiant Heating Film matrix 2 and insulating body 1; Insulating body 1 is provided with Electric radiant Heating Film matrix 2; Electric radiant Heating Film matrix 2 is lenticular structures, and convex portion is provided with conductive silver paste circuit layer 4, and conductive silver paste circuit layer 4 is provided with macromolecule heating layer 3; The two ends external lead wire of Electric radiant Heating Film matrix 2, concave portion is provided with protective layer 5.
Described macromolecule heating layer 3 is carbon slurry heating layer, and protective layer 5 is pressure sensitive adhesive double coated.
