Description

Flake heater
The present invention relates to a kind of flake heater, in more detail, relate to a kind of like this flake heater: banded space pattern according to the rules prints (print) elargol on insulated substrate, print carbon paste then on the elargol layer.When on described elargol layer, printing carbon paste, all apply carbon paste on space residual fraction and the elargol layer, thereby form a kind of flake heater that electrode connects side by side.
Electric heater in the past, major part are the heaters that power supply is connected nichrome wire.Have the heater that power supply is connected to the heated filament front end back on glass now at automobile.Because these conventional heaters all can not be used on the fixed mirror such as the side mirror of automobile or bathroom, so the planar heater that people have proposed to use on mirror particularly has planar heater of double-layer structure etc. patents such as () seeing Japanese kokai publication hei 8-64352 number.But the shortcoming of these planar heaters is complex manufacturing technology, the cost height.
The structure of the planar heat producing body that conventional mirror is used is very complicated, makes difficulty, owing to used the terminal extraction electrode, so it is slow to conduct heat, is necessary to be improved aspect the heat efficiency.Therefore, the present inventor is for improving the problems referred to above, the solution below providing, i.e. according to the rules banded space pattern printing elargol on insulated substrate, the carbon paste of printing coating thereon then.When wherein on elargol, printing, all apply the carbon paste layer on space residual fraction and the elargol layer.The problems referred to above have been improved by realization of the present invention like this.
Brief description of drawings
Fig. 1 shows and use elargol of the present invention on substrate, and prints carbon paste thereon, thereby forms the plane graph of the flake heater of banded carbon paste layer.
Fig. 2 is vertical sectional drawing of the flake heater of Fig. 1.
Describe the present invention with reference to the accompanying drawings in detail.
Fig. 1 shows the plane graph of flake heater 1 of the present invention.As shown in Figure 1, flake heater of the present invention is by insulated substrate 2, banded carbon paste layer 4, elargol layer 3 and power supply terminal 5,5 ' formation.
Wherein, employed silver powder is fine silver powder (purity is more than 99%) in the elargol, and its granularity can reach 250 sieve meshes, and the silver powder conductive capability is extremely strong, also can adopt the silver powder of the satisfied aforementioned condition of selling on the market.The content of used silver is the 50-80% of its weight with respect to resin in the elargol.
In addition,, do not have restriction especially, still,, preferably use the good carbon of selling on the market of thermal conductivity because armorphous carbon thermal conductivity is not so good as long as the carbon that uses in the carbon paste has heat conductivility.The pyroconductivity of these carbon can reach 37.7 * 10 -3More than the degcmsec, as Powdered CSP, the CP that can adopt Japanese carbon company, β 5 (more than be trade name), and the TOKABACK (trade name) of Japanese East Sea carbon company etc.
The heat transfer property of these carbon has nothing in common with each other, and can suitably select its use amount to regulate heat conductivility.Best, the content of carbon dust be by weight be used for carbon paste resin 10～50%.
The resin that uses in described elargol and the carbon paste easily with silver or carbon blending, and has adherence as long as the thermal change performance is little, is insoluble in water and get final product, and nothing limits especially, can use resins such as polyester, polyacrylate, polyamide, and wherein polyester is best.
Utilize method that described elargol and carbon paste make flake heater as shown in the figure.All apply elargol in the printing except that the place that has applied banded carbon paste on the plate shape substrates, all applying carbon paste in the printing in the localities at all then.Promptly all do not apply carbon paste described being coated with on the place that applies elargol and the elargol.Once more,, form adhesive phase 6, form again thereon and separate ply of paper according to known method applying adhesive successively.
In addition, on reverse side (surface) elargol layer 3, be provided with electrode 5,5 '.As shown in Figure 1, elargol layer 3 is divided into two parts by carbon paste 4, and electrode 5,5 ' to form the parallel connection of electric current is set respectively on the elargol 3 that is divided into two parts.
When input supply terminal 5,5 ' voltage when being 10V-30V, the resistance of carbon paste layer is 7-15 Ω, can remove materials such as frost this moment efficiently.If when input voltage is 100V or 220V, easily causes the sintering of carbon component in the carbon paste layer, thereby burn flake heater of the present invention.Therefore, when using the high voltage source of 100V or 220V, the resistance value that must make the carbon paste layer is up to 100-650 Ω, and side-view mirror or supply power voltage that flake heater of the present invention not only can be applied to automobile are on the article of 10-30V, can also be applied on the high voltage supply article of 100V or 220V.
Specify the present invention below in conjunction with embodiment and test example, still, the present invention is not limited to this embodiment and test example.
Embodiment 1
At first, the ratio of alkyd resin with 1.4: 1 is dissolved in the molten cellosolve of acetate butyl (butylcellosolve acetate), in being the fine silver powder (99.5%) of 250 sieve meshes, granularity mixes described polyester solution then with the ratio of 7: 3 (weight ratio), then it is coated on the polyester sheet pattern of removing carbon paste layer (black band shape) shown in Figure 1, forming thickness is the elargol layer of 10 μ m.Then, in described polyester solution, admix the carbon of the TOKANLACK (trade name) of Japanese East Sea carbon company, it is coated on the described elargol layer, form the thick carbon paste layer of 10 μ m with the ratio of 6: 5 (weight ratio).Like this, just formed banded carbon paste layer 4 and elargol layer 3 as shown in Figure 1.
After this, behind coating carbon paste layer, apply double-sided insulation adhesive tape or adhesive thereon.Consider that from the industrial production and the aspect that reduces cost preferably applying heat melts ethylene vinyl acetate (ethylene Vinylacetate), stick separation paper thereafter, as shown in Figure 1, on the elargol layer, power supply terminal is installed, make flake heater of the present invention.
The flake heater of making like this, when high pressure 100V, its resistance reaches 125 ± 20 Ω; During 220V, resistance is up to 550 ± 100 Ω, thereby makes the electric heater operate as normal.When low pressure (10-30V), resistance is 7 ± 2-12 ± 2 Ω, also can operate as normal, thus can remove materials such as fog, frost, ice at short notice efficiently, be suitable in automobile side-view mirror and bathroom mirror, using.The test example
