Micro attenuation power can be cut carbon fiber electric heating plate and its preparation method

Abstract

The invention discloses a micro-attenuated power cuttable carbon fiber electric heating plate and a preparation method thereof. Micro-attenuated power cuttable carbon fiber electric heating plate includes upper decorative paper layer, upper insulating layer, heating chip layer, lower insulating layer, lower decorative layer; upper decorative paper layer, upper insulating layer, heating chip layer, lower insulating layer, lower decorative layer Overlap from top to bottom in sequence; the heating chip layer is composed of a plurality of flat carbon fiber heating non-woven papers connected in parallel with each other through copper tapes. Among them, the dimensions and specifications of the plurality of carbon fiber heating non-woven papers are the same; the upper and lower sides of the copper tape are connected to the upper and lower sides of the carbon fiber heating non-woven paper in sequence. The invention adopts carbon fiber electric heating non-woven paper as the heating chip, the paper is thin, water-resistant, anti-strain elastic, good in penetrating glue, high in composite strength, lower in attenuation power than wood pulp conductive paper, long in service life, can be cut, convenient in installation, and prolongs the The service life of the carbon fiber heating plate reduces the unnecessary production of multiple specifications.

Description

technical field [0001] The invention relates to a micro-attenuation power cuttable carbon fiber electric heating plate and a preparation method thereof. Background technique [0002] The carbon fiber electric heating plates currently produced have the disadvantages of large attenuation power, inability to cut, and short service life. details as follows: [0003] 1. Conductive paper; the conductive paper material is the biggest factor affecting the power drop. The heating material used in the electric heating plate in the prior art is wood pulp fiber conductive paper. This kind of wood pulp conductive paper is not resistant to water, has no elasticity, and the paper is thick. When pressing with the insulating material, due to poor glue penetration, the bonding between the insulating material and the conductive paper is not firm. The electric heating plate is dry in winter and damp in summer. The strength and strain capacity of the electric heating plate gradually decrease ov...

Problems solved by technology

[0003] 1. Conductive paper; the conductive paper material is the biggest factor affecting the power drop. In the prior art, the heating material used in the electric heating plate is wood pulp fiber conductive paper. This kind of wood pulp conductive paper is not resistant to water, has no elasticity, and the paper is thick. When pressing with the insulating material, due to poor glue penetration, the bonding between the insulating material and the conductive paper is not firm. The electric heating plate is dry in winter, and the electric heating plate is damp in summer. The strength and strain capacity of the electric heating plate gradually decrease over time. The bonding force between the internal wood pulp fibers is gradually weakened, and the contact force between the carbon fibers is also gradually weakened, and the resistance of the electric heating plate becomes larger, resulting in a gradual decrease in the power of the electric heating plate. Board service life

[0004] 2. The entire heating chip electric heating plate with different sizes and specifications can only be produced in the factory, and cannot be cut according to the needs when using it, which is very inconvenient for installation and construction.
