Carbon-fiber heating sheet, production method and heating physiotherapy device

Abstract

The invention relates to a carbon fiber heating sheet, a production method and a heating physiotherapy device. A carbon fiber heating sheet comprises a carbon fiber heating bundle, Electrode strips bonded by conductive adhesive and in electrical contact with the carbon fiber heating beam are respectively coated on both sides of the carbon fiber heating beam, and conductive cloth which is laid along the length direction of the electrode strips and in electrical contact with the carbon fiber heating beam and the electrode strips respectively is composed of the electrode strips and the carbon fiber heating beam in the length range in contact with the carbon fiber heating beam. A manufacture method comprises that follow steps of: 1) arranging carbon fiber heat bundle on a base cloth to form acarbon fiber layer; 2) spraying a non-conductive adhesive on that carbon fiber lay and leaving an electrode strip laying position, and the electrode strip laying position is not sprayed with the non-conductive adhesive; 3) spraying conductive adhesive on that electrode strips to make the electrode strip adhere to the carbon fiber layer to form an electrode strips lay; 4) laying a conductive clothalong that length direction of the electrode strip, wherein the conductive cloth is respectively in electrical contact with the carbon fiber lay and the electrode strip; 5) laying upper cover cloth toform an upper cover cloth layer, and bonding the upper cover cloth layer with a base cloth, a carbon fiber layer and a conductive cloth by glue.

Description

technical field [0001] The invention relates to the technical field of carbon fiber heating, in particular to a carbon fiber heating sheet, a production method and a heating physiotherapy device. Background technique [0002] Carbon fiber heating can release far-infrared rays that are conducive to human body absorption. It is a better way of heating physiotherapy, and the electrothermal conversion rate is as high as 95% during heating, which saves energy compared with traditional technology. However, there is a problem in the existing carbon fiber heating --- loose contact leads to sparking. The reason is: the main component of carbon fiber is carbon, and the melting point of carbon is 3500 degrees. Even the melting point of synthetic carbon fiber is above 1000 degrees, so that the carbon fiber and the metal electrode cannot be welded and are prone to loosening. At this time, the carbon fiber and the metal electrode cannot be electrically connected. There is a potential dif...

However, there is a problem with the existing carbon fiber heating --- loose contact leads to sparks

The reason is: the main component of carbon fiber is carbon, and the melting point of carbon is 3500 degrees. Even the melting point of synthetic carbon fiber is above 1000 degrees, so that the carbon fiber and the metal electrode cannot be welded and are prone to loosening. At this time, the carbon fiber and the metal electrode cannot be electrically connected. potential difference

In addition, carbon fiber is easy to break, which further increases the risk of ignition
