Embodiment 1

[0031] A mica plate-coated electric heating device comprises a mica-coated electric heating plate 1, a mica insulating guard plate 2, an edge protector 3, an electrode silver paste belt 4 and a power lead 5. The mica-coated electric heating board 1 is composed of a mica plate 11 and a conductive film coating 12 cured on the surface of the mica plate 11. The electrode silver paste belt 4 is cured at the outer edges of the left and right sides of the conductive film coating 11. The mica insulation The guard plate 2 is covered on the side of the mica-coated electric heating plate 1 sprayed with the conductive film coating 12, and the edge guard 3 is fixedly installed around the mica insulating guard plate 2 and the mica-coated electric heating plate 1; The electrode silver paste strips 4 on both sides are connected.

[0032] Preferably, the power wire 5 is riveted on the mica-coated electric heating plate 1 through the electrode copper pressing sheet and the terminal with copper ...

Abstract

The invention relates to a mica plate coating electric heating device and a manufacturing method thereof. The device comprises a mica coating electric heating plate, a mica insulation guard board, a safe edge sheath, electrode silver paste tapes and power supply leads. The mica coating electric heating plate is formed by a mica plate and a conducting film coating solidified on a mica plate surface. The electrode silver paste tapes are solidified on outer edges of left and right sides of the conducting film coating. The mica insulation guard board covers one side of the mica coating electric heating plate, wherein the side is sprayed with the conducting film coating. The safe edge sheath is fixedly installed on peripheries of the mica insulation guard board and the mica coating electric heating plate. The power supply leads are connected with two sides of the electrode silver paste tapes respectively. According to the invention, a heating speed is fast. A service life is long. A yield ratio is high. High / low voltages and alternating current / direct current are suitable. The device and the method can be widely used in electric appliances, such as a household appliance, technology drying equipment, a health care product and the like.

Description

technical field [0001] The present invention relates to a non-metallic film electric heating product and its manufacturing method, in particular to a non-metallic film electric heating product made of composite materials and its manufacturing method, in particular to a mica plate coated electric heating Heat generating device and manufacturing method thereof. Background technique [0002] The current electrothermal film is mainly composed of two categories, one is hard mold, which is in sheet or plate shape, usually made of carbon fiber distributed in thermosetting resin, or metal is pressed into thin strips and sealed in mica and other insulating materials. This type of film has a high service temperature, but the electrothermal conversion rate is low, generally lower than 80%, and the attenuation is large, and it cannot work stably during use, is prone to pollution, and is not safe to use. The other type is soft film, which is made of electric heating material into paste,...
