Description
Technical field
The present invention relates to the electric heating element technical field, particularly relate to a kind of electric heating semiconductor film heating element and preparation method thereof.
Background technology
The polytetrafluoroethylplastic plastic electric heating semiconductor film has softness, folding, corrosion-resistant, advantage such as heating is fast, heating is even, energy-conservation, so the planar heat producing body that the polytetrafluoroethylplastic plastic electric heating semiconductor film is made has purposes very widely.But also just owing to the characteristic of polytetrafluoroethylplastic plastic electric heating semiconductor film, feasible bigger with its difficulty of processing of making heater element, especially the insulation on the installation connection of electrode and heater element surface is more difficult.
The polytetrafluoroethylplastic plastic electric heating semiconductor film heating element generally is made of electric heating semiconductor film, electrode, electrode outlet line and surface insulation layer.The manufacture method of existing polytetrafluoroethylplastic plastic electric heating semiconductor film heating element is: the square matrix material that electric heating semiconductor film is cut into preseting length and width; At the two ends of electric heating semiconductor film square matrix material brush silver slurry, be covered with Copper Foil again as electrode; After treating that the silver slurry solidifies, lead-out wire is welded on the electrode with scolding tin; Paste adhesive plaster or micarex or epoxy resins insulation plate or materials such as rubber slab or plastic plate on electric heating semiconductor film square matrix material two sides as insulation processing with glue or adhesive sticker.But the electric heating piece of making like this, between its electrode and the electric heating semiconductor film and the fastness that is connected between outer layer insulation material and electric heating semiconductor film, the electrode not high, phenomenon such as therefore cause easily that the electric heating semiconductor film heating element insulating reliability is poor, electrode and lead-out wire easily come off has seriously influenced the application of electric heating semiconductor film heating element thus.
Summary of the invention
The purpose of this invention is to provide a kind of electric heating semiconductor film heating element and preparation method thereof, the fastness that is connected of the insulating reliability of the electric heating semiconductor film heating element of Zhi Zuoing, electrode and lead-out wire all obviously improves than existing electric heating semiconductor film heating element in this way.
Technical scheme of the present invention is as follows:
A kind of electric heating semiconductor film heating element is by electric heating semiconductor film, electrode, electrode outlet line and insulating barrier constitute, it is characterized in that described electric heating semiconductor film is the polytetrafluoroethylplastic plastic electric heating semiconductor film, described electrode is made of silver slurry coating and Copper Foil, banded silver slurry coating is positioned at the two ends of polytetrafluoroethylplastic plastic electric heating semiconductor film, Copper Foil posts on silver slurry coating, Copper Foil, silver slurry coating and electric heating semiconductor film three sew up with fine rule, the described insulating barrier tight covering electric heating semiconductor film that to be one deck form with melt process and the hot melt insulating material of electrode, described insulating barrier also has one deck reinforced insulation layer outward.
The manufacture method and the processing step of above-mentioned electric heating semiconductor film heating element are as follows:
A. the polytetrafluoroethylplastic plastic electric heating semiconductor film is cut into the blank of setting shape and size by designing requirement;
B. at the two ends of polytetrafluoroethylplastic plastic electric heating semiconductor blank brush silver slurry, Copper Foil is pasted on the silver slurry;
C. after treating that the silver slurry solidifies, Copper Foil, silver slurry coating and electric heating semiconductor film three are sewed up, reinforced with fine rule;
D. with scolding tin lead-out wire is welded on the Copper Foil;
E. at the above-mentioned electrode that preset, hot melt film is spread on the two sides that has connected the blank of lead-out wire, and hot melt film covers whole polytetrafluoroethylplastic plastic electric heating semiconductor film blanks, electrode and part lead-out wire;
F. press design code, outside hot melt film or spread cotton or micarex or epoxy resins insulation plate or plastic plate or linings such as rubber slab or polyester plate;
G. hot forming under the particular thermal melting temperatur.
If electric heating semiconductor film heating element is used for the occasion of working temperature below 80 ℃, then insulating barrier uses ethylene-vinyl acetate copolymer (EVA) hot melt film, and reinforced insulation layer uses the cotton yarn cloth.If electric heating semiconductor film heating element is used for the occasion of 50 ℃～200 ℃ of working temperatures, then insulating barrier uses polyurethane-hot melt film or polyester hot melting film, and reinforced insulation layer uses epoxy resins insulation plate or plastic plate or polyester plate or rubber slab or micarex.
The electrode of electric heating semiconductor film heating element provided by the invention is made of silver slurry coating and Copper Foil, and again with fine rule sewn reinforcement in addition, so electrode combines firmly the lead-out wire convenient welding with electric heating semiconductor film; Because of melt process insulating barrier that is shaped and the combination of elements compact and firm that is capped, therefore significantly improved the insulation property of heater element on the one hand again, further improved electric heating semiconductor film and electrode and the be connected fastness of electrode on the other hand with lead-out wire.
