Abstract
The utility model discloses a high-molecular electric heating film, which comprises an electric heating film matrix and an insulation matrix. The electric heating film matrix is arranged on the insulation matrix and is of a concave and convex type structure. The convex part of the electric heating film matrix is provided with a conductive silver paste circuit layer and the concave part of the electric heating film matrix is provided with a protective layer. A high-molecular heating layer is arranged on the conductive silver paste circuit layer and the two ends of the electric heating film matrix are provided with external leads. The high-molecular electric heating film has the advantages of simple structure, convenient machining, low cost, high safety, wide application range, good heat dissipation effect and long service life.
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: a kind ofly be the metal semiconductor type, the metal semiconductor type need be used vacuum coating equipment, complex process, and equipment investment is large; A kind of is glass, ceramic mould, and it is the film body with some strength and rigidity, can only be coated on that glass, pottery etc. are upper to be used, and insulation property are poor, and quality is crisp, and is fragile, can not push, folds, crooked, and its range of application is subject to certain restrictions; 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 is that Electric radiant Heating Film is being covered uniformly on the insulating body material, on the 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 same integral planar shape, and the thickness of Electric radiant Heating Film has certain impact to resistance.When heating power, whole planar Electric radiant Heating Film is easy to the power electrode contact position and produces large 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 for 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 solution adopted in the utility model is such: a kind of polymer electric heating membrane; comprise 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 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, the two end portions projection.
Compare with the existing product technology, the utility model has the advantage of: have the function that prevents because electric current increases and heating causes fire hazard rapidly, product is fire-retardant, safe, product is counter-bending, anti-aging, tear-proof, resistance to corrosion are strong, and the utility model all can normally not use in the situations of folding 180 degree.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 the 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 affect the normal heat transmission function of other parts.
Description of drawings
Fig. 1 is structural representation of the present utility model.
