Abstract

The invention discloses a far infrared heating plate and a manufacturing method thereof. The far infrared heating plate comprises an aluminium substrate, a first polyimide thin film layer, infrared slurry, a copper foil conduction band, a second polyimide thin film layer and the like. The method provided by the method comprises the following steps of: firstly, coating the first high-temperature resistant polyimide thin film layer on the aluminium substrate, printing the infrared slurry on the coated aluminium substrate, and pasting the copper foil conduction band pasted with conductive dual-sided adhesive on the infrared slurry of the aluminium substrate; secondly, coating the second polyimide thin film layer with good insulation performance; finally drilling a welding hole for welding a lead, and pasting an insulation cap to obtain the far infrared heating plate. After the far infrared heating plate is electrified, the copper coil conduction band and the infrared slurry have uniform contact and good conductive effect and are safe and reliable. The heating plate has the advantages of rapidness for raising temperature, uniform heat conduction, long service life and simple structure. The manufacturing method for the far infrared heating plate has simple process, is easy to carry out and can be applied indoors in quantity as heating layers of wallboards and floors to achieve goodgreenhouse effect; furthermore, the far infrared heating plate can be widely applied to the apparatuses in a dry steam room.

Description

technical field [0001] The invention relates to the field of far-infrared heating plates, in particular to a far-infrared heating plate and a manufacturing method thereof. Background technique [0002] The traditional far-infrared heating plate is made of ceramic materials, which has the disadvantages of low power, poor temperature uniformity, and easy dust accumulation, so it cannot be used in the production process of advanced precision products. The other is a large-scale heating plate, which is made of aluminum alloy and cast into one body with a tubular electric heating tube, which has the disadvantages of poor temperature uniformity, high cost, and difficult maintenance. In terms of heat preservation and heating, manufacturers of electric heating plates and heaters have begun to use carbon fiber materials to make electric heating plates. The imaginary structure is simple: the carbon fiber material is sandwiched between the upper and lower layers of insulating plates an...
