Embodiment 1

[0027] Prepare the coating solution according to the following raw material formula and weight ratio: the coating solution is 35% of tin tetrachloride, 12% of antimony trichloride, 8% of glycerin, and the rest is solvent.

Embodiment 2

[0029] Adopt the coating liquid of embodiment 1 preparation to produce nano electric heating film heating element:

[0030] The first step of spray film:

[0031] Put the prepared component base material into the coating furnace whose temperature has reached about 400 degrees, close the furnace door, and when the temperature rises to the set temperature of 700 degrees, spray the coating solution into the furnace, and take it out after the power reaches the required range Cool the components to room temperature;

[0032] Step 2: Apply sintered electrodes:

[0033] The electrode should be applied to the appropriate position with the electric heating film. Use a screen printing machine or manual operation, and put it into the baking plate furnace when it is slightly dry. When the temperature reaches the set temperature of 500-600 ° C, keep the temperature for 15 minutes, take it out and cool it. , which is the nanometer electrothermal film heating element. The resulting produc...

Embodiment 3

[0035] The first step and the second step are the same process as in Example 2 to manufacture the nano-electrothermal film heating element, and the third step is to make the electrode card or the lead wire: when the pipe is used as the electrode card, it is cut from thin plates such as stainless steel, copper plated with silver, and phosphor copper. A strip of appropriate length and width, with holes punched at both ends of the metal strip, is fastened on the electrode 3 with screws.

[0036] can also be as Image 6 Copper-tinned conductive braid is used, and cold-rolled terminals are riveted on both ends as the lead wire 4, and then fastened to the electrode by screws or welded to the electrode 3.

[0037] Such as Figure 5 As shown, plate-shaped or special-shaped components are used, and the lead-out wire 4 is compressed by welding, riveting or drilling, and fastened with screws.

[0038] Such as Figure 4 The inner coating tube shown uses a spring retaining ring, a press...

Abstract

The present invention relates to electric heating elements. The nanometer electrothermal film heating element adopts following coating liquid to form electrothermal film on the high temperature resistance insulated base material; thecoating liquid is 30-40% stannic chloride, 10-15% trichloride antimony, 5-10% propanetriol; the rest is solvent; the electrothermal film is coated with electrode. The nanometer electrothermal film heating element in the present invention conquers the shortcoming problems in the existing technology, improves the quality, reduces the cost and enlarges the application range of the product; the formulation of new electrothermal film coating liquid is simple, rational and suitable for wide base material; the produced heating elements have infrared irradiation function and are innoxious, flavorless, save energy and protect the environment. The producing process is simple and easily operated; the obtained product has high quality. The heating device using the nanometer electrothermal film heating element can be both instantaneous type and burning type; and the invention has good performance and wide use.
