Problems solved by technology

[0002] Conventional electric heating products usually use stiff, fragile, and not soft heating elements such as electric heating sheets, electric heating wires, or electric heating tubes. Such electric heating products are prone to uneven and improper curling due to the shape of the heating element. Folding will cause damage to the heating element, and it may cause dangerous situations such as wire fire, so there are still many inconveniences and dangers in use. Although another emerging carbon fiber heating element can overcome the above inconveniences, it is complicated due to its complicated manufacturing process. Due to factors such as pollution and high cost, the prices of related products remain high, which reduces consumers' willingness to buy

Embodiment Construction

[0018] Please refer to Fig. 1, the flexible electric heating element 1 of the present invention, it comprises a substrate 10, a heating metal coating 101 and a far-infrared carbon film 102, and this heating metal coating 101 and far-infrared ray carbon film 102 with a vacuum coating technology A carbon film 102 is stacked and deposited on the outer layer of the substrate 10 . The base material 10 is an insulating material. The insulating material can be a flexible insulating material such as soft board, fiber bundle, fiber woven cloth or non-woven cloth, and is preferably an insulating material such as polymer fiber cloth or glass fiber cloth. The heat-generating metal coating 101 is used to heat up and generate heat after being electrically connected to the circuit. The metal can be niobium, molybdenum, tantalum, tungsten, rhenium, titanium, vanadium, chromium, zirconium, hafnium, ruthenium, osmium or iridium, etc., suitable for use in vacuum The refractory metals and their a...

Abstract

This invention proposes a flexible electrical heating element comprising a substrate, a metal interlayer coating and a far-infrared emissive carbon film. The flexible electrical heating element utilizes a low-cost and environmental friendly vacuum coating technique to deposit the metal interlayer coating and the far-infrared emissive carbon film on the flexible and insulating substrate which can provide uniform heating, and the far-infrared emissive carbon film can emit far-infrared.

Description

technical field [0001] The invention relates to an electric heating material, in particular to a flexible electric heating body and a manufacturing method thereof. Background technique [0002] Conventional electric heating products usually use stiff, fragile, and not soft heating elements such as electric heating sheets, electric heating wires, or electric heating tubes. Such electric heating products are prone to uneven and improper curling due to the shape of the heating element. Folding will cause damage to the heating element, and it may cause dangerous situations such as wire fire, so there are still many inconveniences and dangers in use. Although another emerging carbon fiber heating element can overcome the above inconveniences, it is complicated due to its complicated manufacturing process. Due to factors such as pollution and high cost, the price of related products remains high, which reduces consumers' willingness to buy. Contents of the invention [0003] In...
