Problems solved by technology

[0003] With the increasing awareness of environmental protection, higher requirements are put forward for the performance and use of heating cables, especially in terms of energy saving, safety and environmental protection. In the past heating cables, the conductor core material is made of metal alloys, especially copper alloys. Mainly, although the metal alloy core material has good electrical and thermal conductivity, there are deficiencies in use, improper technical handling, easy to generate electromagnetic radiation after power-on, which will have adverse effects on the elderly, children, and pregnant women, and the texture is relatively hard. Bending will be easily damaged, and the mechanical properties are not good

Abstract

The invention discloses a carbon fiber heat generation cable for underfloor heating. The carbon fiber heat generation cable comprises a carbon fiber composite core material, a resin layer, an insulation layer and an outer skin protection layer, wherein the resin layer, the insulation layer and the outer skin protection layer sequentially wrap the carbon fiber composite core material, the carbon fiber composite core material is formed by twisting a modified carbon fiber beam and an alloy wire, and the modified carbon fiber beam is made of zinc oxide whisker modified PAN-based carbon fiber. The modified carbon fiber beam and the alloy wire are twisted to fabricate the carbon fiber composite core material, the zinc oxide whisker is added into the modified carbon fiber beam, thus, the heat conduction performance and the heat conversion rate of the core material are improved, and the dynamic property is improved; and by matching the resin layer wrapping the carbon fiber composite core material, the total released heat is reduced, the smoke release quantity is increased, the flame retardance can be improved to a certain extent, and the safety coefficient is improved.

Description

technical field [0001] The invention relates to the technical field of heating cables, in particular to a carbon fiber heating cable for floor heating. Background technique [0002] Nowadays, heating cables are widely used to achieve the purpose of keeping warm and increasing temperature. Heating cables are made of heating wires into cable structures, use electricity as energy, and use alloy resistance wires to conduct electricity and generate heat to achieve heating or heat preservation effects. Floor heating is mainly divided into water floor heating and electric floor heating. Among them, electric floor heating uses a low-temperature heating cable as a heat source to heat the floor or floor tiles, and supplies heat to the room through the ground through radiation and convection heat transfer. Geothermal cables have the characteristics of high thermal conductivity, fast heat dissipation, and high electrothermal conversion efficiency. [0003] With the increasing awareness...
