Abstract

The invention provides a carbon fiber heating wire for melting snow and ice on roads and bridges, which comprises an inner layer heating wire bundle, a carbon nano tube bucky paper glass fiber epoxy resin layer, a polytetrafluoroethylene layer, a crosslinked polyethylene layer and a stainless steel woven mesh sleeve which are sequentially wrapped from inside to outside. The inner layer heating wire bundle is used as an inner layer heating layer and consists of a plurality of carbon fiber heating wires; the carbon nano tube bucky paper glass fiber epoxy resin layer is used as a heat diffusion layer, the polytetrafluoroethylene layer is used as a middle layer, the crosslinked polyethylene layer is used as a secondary outer layer, and the stainless steel woven mesh sleeve is used as an outermost layer. Through the arrangement of the carbon fiber heating wire bundle, rapid heating, high electrothermal conversion efficiency, high tensile strength, light weight, stable chemical performance and long service life are realized, through the arrangement of the middle carbon nano tube bucky paper glass fiber epoxy resin layer, the overall heat transfer radius of the heating wire is enhanced, the heat loss in the outward heat transfer process of the heating wire is reduced, and rapid temperature rise, effective heat transfer, stability and durability can be ensured.

Description

technical field [0001] The invention relates to the technical field of road and bridge snow melting and ice melting, in particular to a carbon fiber heating wire for road and bridge snow melting and ice melting. Background technique [0002] Currently widely used methods for melting snow and ice on roads and bridges include manual removal, mechanical removal, and chemical snow melting. The application of electrothermal method to melt snow and ice on roads and bridges can solve the shortcomings of the above methods. [0003] Carbon fiber is a new type of high-performance fiber-reinforced material with many excellent properties such as high strength, high modulus, high temperature resistance, wear resistance, fatigue resistance, corrosion resistance, creep resistance, electrical conductivity, thermal conductivity and high electrothermal conversion efficiency. But when the heating wire adopts carbon fiber heating wire, there are the following problems: [0004] 1. The heat tr...
