Problems solved by technology

However, the electric heating elements of this kind of heating equipment are often exposed or are only simple isolation measures, which have certain safety hazards. At the same time, because electric energy is a high-priced energy source, if the heat conversion efficiency of the equipment is not high, it does not meet the low-carbon environmental protection requirements. Life requirements, so it is not suitable for long-term use

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 As shown, Embodiment 1 provides a mica electrothermal film, which is a composite three-layer structure, with an alloy foil 2 etched with a heating circuit in the middle, and a mica substrate 1 on both sides of the heating element. The mica substrate 1 is 0.3mm thick mica laminated paper. The alloy foil 2 and the mica substrate 1 are uniformly coated with a high-temperature adhesive and pressed through a high-temperature pressing process to obtain a mica electric heating film. The mica electric heating film of this structure uses the heat transfer method of hot air convection.

[0026] Such as figure 2 As shown, Embodiment 2 provides a mica electrothermal film, the electrothermal film is a composite five-layer structure, followed by mica substrate 1, alloy foil 2, mica substrate 1, aluminum foil 2, mica substrate 1, the mica s...

Abstract

The invention relates to the field of mica material processing, in particular to mica electro-thermal film. The mica electro-thermal film is in a composite multilayer structure, the middle layer is a heating element, and two sides attached to the heating element are mica substrates. The heating element is an alloy foil sheet with a heating circuit etched, the mica substrates are mica laminated paper, and the electro-thermal film is formed by pressing the alloy foil sheet and the mica substrates through high-temperature adhesives and a high temperature pressing process. The mica electro-thermal film is simple in structure and high in thermal conversion efficiency; and heating equipment produced through the mica electro-thermal film meets utilization requirements of being safe and comfortable and environment friendly and energy saving.

Description

technical field [0001] The invention relates to the field of mica material processing, in particular to a mica electric heating film. Background technique [0002] Mica paper is a kind of high-quality insulating material, which has the advantages of non-toxic, odorless, high temperature resistance, high pressure resistance, aging resistance, corrosion resistance, stable electrical performance, etc., especially its high temperature resistance and reworkability are irreplaceable by other materials Therefore, mica paper is more and more used in all aspects of life. [0003] Traditional heating sources include burning fuel and generating heat with electric heating elements. Although the former has a high heat conversion rate, it pollutes the environment more seriously. The latter is a variety of heating equipment made of electric heating elements. It uses air convection to transfer heat to a certain space. It is easy to install and easy to use at home. However, the electric h...
