A heat conducting insulated protective layer of the existing electric heating film is easy to fall and has poor heat conducting capacity, and electric heating core materials have poor reliability. The utility model comprises an alloy heating body and a heat conducting insulated silicone rubber protective layer in order to solve the technical problems, wherein the heat conducting insulated silicone rubber protective layer is positioned out of the alloy heating body and the heat conducting insulated silicone rubber protective layer which is incompletely vulcanized before molded can be completely vulcanized after molded at a high temperature between 150 DEG C and 220 DEG C and can be integrally compounded with the alloy heating body. The heat conducting insulated silicone rubber protective layer after surface is processed by silicone rubber surface treating agent can be pasted on the surface of the heating body via high temperature resisting double-side adhesive when paste is needed. Due to the adoption of the technical scheme, the novel soft type heat conducting insulated silicon rubber electric heating element having the advantages of simple structure, convenient operation and firmness can be widely used for occasions needing electric heating.
Description
Technical field
The utility model relates to a kind of electric heating element, particularly a kind of soft heat-conducting insulating silicon rubber electric heating element.
Background technology
Electric radiant Heating Film is a kind of film of general electricity heating, has good exchange to contact with heating object.Heat efficiency height, the flames of anger, heating film takes up space hardly, because self-temperature is also not really high,, make utensil light and handy unusually for insulation, heat insulation greatly simplification, the thermal capacity of Electric radiant Heating Film is little, and thermal source is opened and turn-offed rapidly, also has advantage water-fast, acidproof, alkaline-resisting and that mechanical strength is high.For preventing short circuit, electric shock or electric-heating thin film wearing and tearing, usually this electric-heating thin film surface is with the heat conductive insulating protective layer, but existing insulating protective layer is to paste by adhesive to fix, under the condition of high temperature or be subjected to external force and do the time spent, insulating protective layer come off easily and the capacity of heat transmission very poor; Existing electrothermal chip adopts resistance slurry, graphite mixture printing to form mostly, and easy to crack, its reliability is under suspicion.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome existing Electric radiant Heating Film, provides a kind of heat conductive insulating protective layer of high thermal conductivity not allow the good soft heat-conducting insulating silicon rubber electric heating element of caducous reliability.
For solving the problems of the technologies described above, the soft heat-conducting insulating silicon rubber electric heating element of the utility model comprises the alloy heat generating body, it is characterized in that: described alloy heat generating external surface is covered with the heat-conducting insulating silicon rubber protective layer; This heat-conducting insulating silicon rubber protective layer was incomplete vulcanization before mold pressing, complete cure just behind 150 ℃ of-220 ℃ of hot press mouldings, and with alloy heat generating bluk recombination becomes an integral body.
So design, with the silicon rubber of incomplete vulcanization be attached to alloy heat generating external after, complete cure behind 150 ℃ of-220 ℃ of hot press mouldings, and become an integral body with the alloy heat generating bluk recombination.The Electric radiant Heating Film of the existing layer structure that this structure is fixing with relying on the adhesive adhered layer has essential distinction.The heat-conducting insulating silicon rubber protective layer is under the condition of high temperature or be subjected to external force and do the time spent, heat conductive insulating protective layer difficult drop-off.Heater adopts alloy material, can guarantee that heater does not damage in the hot press moulding process.
As optimization, described alloy heat generating body is chromium foil, nickel filament or similar alloy material.So design is convenient to make.
As optimization, described heat-conducting insulating silicon rubber protective layer thickness is 0.1-1.5mm.The heat-conducting insulating silicon rubber protective layer thickness is excessive, and then heat conductivility can be weaker; Described heat-conducting insulating silicon rubber protective layer thickness is too small, and then insulation property, anti-wear performance are weaker.So design can guarantee that this soft heat-conducting insulating silicon rubber electric heating element has good heat-conducting, insulation property and anti-wear performance.
As optimization, handle through the silastic surface inorganic agent on the heat-conducting insulating silicon rubber protective layer surface of described soft heat-conducting insulating silicon rubber electric heating element one side, and covered high temperature resistant double faced adhesive tape.So design is convenient to install and fix.
In technique scheme, the design people has proposed with metal alloy as heater, and heat-conducting insulating silicon rubber is the desirable substitute products of existing Electric radiant Heating Film as the new technology and the new technology of the Electric radiant Heating Film (sheet) of substrate.
Through etching or be photo-etched into certain shape, two bread are with the heat conductive insulating silica gel material with thickness 0.02mm-0.15mm chromium foil, are shaped and vulcanizing treatment forms through hot press moulding.Can be processed into the film of multiple color, multiple shape, the soft insulate heat rubber electric heating element of leading of different capacity, different heating curves.Electrical equipment capacity tolerance: ± 5%
