According to the transparent heat-emission film of the utility model, the heat-emission film layer is coated on the surface of the substrate, and the heat-emission film layer is matched with conductive electrodes, such that uniform heating performed on the surface of the substrate can be realized, and heating efficiency is improved; thickness of the heat-emission film layer is small, and light transmittance of the heating film layer is excellent, and therefore, it is beneficial to the improvement of the quality of products.
Description
Technical field
The utility model relates to a kind of transparent heating film that uses in electric heater unit.
Background technology
At present, what the heating element that people use adopted usually is lectrothermal alloy wire, electrothermal tube etc., but the heating area of this class component itself is smaller, and heating object can't not accomplished tight contact, the heat that produces just can not be very fast conduct to heating object, make heat on the electrical heating elements too concentrate and local overheating causes a part of heat to lose fast.So the traditional heating element heat efficiency is low, when particularly heating glass, pottery etc. conducted heat object slow, the skewness of lectrothermal alloy wire, electrothermal tube, its heat efficiency were also just lower, and in addition, local overheating also is easy to heating object is burst.
Summary of the invention
The utility model purpose is to provide a kind of transparent heating film, improves the efficiency of heating surface, be difficult for breaking, but and production cost is low, life-span length, corrosion-resistant dry combustion method, can heat thin thickness, good transmittance by non-naked light.
In order to solve these problems of the prior art, the technical scheme that the utility model provides is:
A kind of transparent heating film, described transparent heating film comprises base material, cover layer, heating rete and electrode layer, the described cover layer that covers substrate surface is used for blocking the part that need not to spray heating film on the base material, described heating rete is located on cover layer and the base material, the active position of described heating rete is uncoated tectal position on the base material, is provided with conductive electrode layer at the useful effect face of described heating rete.
Detailed technical scheme is: a kind of transparent heating film, described transparent heating film comprises base material, cover layer, heating rete and electrode layer, the described cover layer that covers substrate surface is used for blocking the part that need not to spray heating film on the base material, described heating rete is located on cover layer and the base material, the active position of described heating rete is uncoated tectal position on the base material, useful effect face at described heating rete is provided with conductive electrode layer, and described heating rete is metal oxide InO
2Film, described cover layer are the physical mixture of big stone flour, M1 water-soluble glue and water.
Than solution of the prior art, the utility model advantage is:
The described transparent heating film of the utility model, it realizes the even heating to substrate surface by applying the heating rete at substrate surface and matching with conductive electrode, improves the efficiency of heating surface, and thin, the good transmittance of heating film layer thickness, be of value to the raising product quality.In addition, scribble cover layer in advance at substrate surface, the thermal effect that adds of product can be effectively improved in the zone of rete spraying but the covering substrates surface need not to generate heat by simple operations, and is workable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of the described transparent heating film of the utility model;
Fig. 2 is making flow chart of the present utility model;
Wherein: 1, base material; 2, heating rete; 3, electrode layer.
Embodiment
Below in conjunction with specific embodiment such scheme is described further.Should be understood that these embodiment are not limited to limit the scope of the invention for explanation the present invention.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
Embodiment:
A kind of transparent heating film, described transparent heating film comprises base material 1, cover layer (not marking on the figure), heating rete 2 and electrode layer 3, the described cover layer that covers base material 1 surface is used for blocking the part that need not to spray heating film on the base material 1, described heating rete 2 is located on cover layer and the base material 1, the active position of described heating rete 2 is uncoated tectal position on the base material 1, useful effect face at described heating rete 2 is provided with conductive electrode layer 3, and described heating rete 2 is metal oxide InO
2Film, described cover layer are the physical mixture of big stone flour, M1 water-soluble glue and water.
The making flow process of concrete this transparent heating film of making is as follows:
(1) the heating rete is with the making of liquid: get InCl
35.2g, SnCl
45H
2O5.2g, BiCl
35.2g, methyl alcohol 450ml, above-mentioned four kinds of materials are poured in the container A, mix, stir, remove HCl100ml, water 460ml is poured in the container B, mix, stir, then the solution in the container B is slowly poured in the container A, slowly stirred simultaneously, as the spray film use of base material heating rete;
(2) cover layer is with the making of liquid: tectal effect is to block the part that does not need to spray the heating rete, get big stone flour 200g, M1 water-soluble glue 20ml and water 200ml, these three kinds of materials are placed in the container, mix, stir, cover as base material and use;
(3) selection of base material: select that conductance, thermal expansion are washed one's face and rinsed one's mouth, insulation resistance, chemical stability, cold-and-heat resistent impact, surface smoothness reasonable material all, can adopt glass, enamel, boccaro, quartz, mica and enamelware;
(4) brush cover layer: with hairbrush the cover layer solution that has configured in the step (2) being coated in does not need to spray the heating film layer segment on the base material, put into drying box then, is warming up to 50
oC, constant temperature took out after 20 minutes;
(5) cleaning of base material: with needing the part wiped clean of spraying heating film on the base material, dry naturally with alcohol;
(6) spraying heating rete: base material is put into baking oven, be warming up to 500
oC(480
oC ~ 650
oBetween the C all can), constant temperature began to spray the heating rete liquid that configures in the step (1) after 10 minutes, base material keeps the rotation of given pace in the whole process, fluid flow and air pressure keep constant value.Utilize chloride (as InCl
