Because the cable is electrified, the installation needs to be particularly cautious, the special production equipment with the technical characteristics in the industry is used for manufacturing the electric wire and the cable so as to adapt to the structure and performance requirements of cable products and meet the requirements of continuous production with large length and high production speed as much as possible, thereby forming a special equipment series for manufacturing the cable, the carbon fiber heating wire is used as one kind of cable, because the carbon fiber has high conversion efficiency to electric energy, the electric heating efficiency is close to 100 percent, the temperature rise is rapid, nearly 30 percent of electric energy in the conversion process is converted into far infrared rays which have a great benefit to human bodies, the far infrared rays are widely applied to the field of heating cables, but in the prior art, because the carbon fiber is not lightfast, most carbon fiber heating wires are made of lightproof materials, but have absorption and reflection effects on the infrared rays emitted by the carbon fiber, and the far infrared rays are absorbed by the cable, and then make cable itself produce the heat, the heat is outdiffusion again, compares in directly using the far infrared to heat the external world, has certain energy loss, and causes pressure to the high temperature resistance of cable itself, and the carbon fiber itself is the heat when circular telegram most electric energy direct conversion, and the heat-sinking capability of cable itself has decided the high temperature resistance of cable to a certain extent simultaneously.
A high temperature cable fluorine silicone rubber high temperature resistant layer and high temperature cable that chinese patent issued, patent number: 2019107611418, which is prepared by mixing the following raw materials in parts by weight: 100 parts of silicon rubber; 38-43 parts of white carbon black reinforcing agent; 9-11.6 parts of a silane assistant; 2-3.5 parts of cerium oxide filler; 0.10-0.18 part of lubricant and 0.5-1.5 parts of vulcanizing agent; wherein the white carbon black reinforcing agent is formed by mixing white carbon black and siloxane containing active hydrogen according to the weight part of 100: 10-18; the vulcanizing agents are one or more of dicumyl peroxide, 2, 5-dimethyl-2, 5-di (tert-butylperoxy) hexane and tert-butyl peroxybenzoate, the invention utilizes the excellent ageing resistance of the fluorosilicone rubber, and adopts the white carbon black reinforcing agent and the cerium oxide filling agent to improve the high temperature resistance of the high temperature resistant layer of the fluorosilicone rubber, so that the ageing resistance of the high temperature cable is improved, but the high temperature resistant layer prepared in the scheme can not play a positive effect on heat conduction and dissipation, and is not beneficial to the heat dissipation in the cable.
Disclosure of Invention
In order to make up for the defects of the prior art and solve the problems that the existing carbon fiber heating wire is low in light transmittance and heat dissipation performance, so that most of heat cannot be conducted to the outside, and high pressure is caused on the high-temperature resistance inside the cable, and the heating wire is not beneficial to quickly raising the temperature of the environment.
The technical scheme adopted by the invention for solving the technical problems is as follows: the invention relates to a high-temperature-resistant carbon fiber cable which comprises a wire core, a high-temperature-resistant insulating layer and an outer protective sleeve; the high-temperature-resistant insulating layer is prepared from the following raw materials:
15-20 parts of silicon rubber, 1.5-3 parts of white carbon black, 0.8-1.4 parts of silicon nitride, 2-3 parts of glass fiber, 5-7 parts of fluororubber, 0.5-0.8 part of stearic acid and 2-3 parts of gum arabic;
the grain diameter of the silicon nitride is controlled to be 5-20 mu m;
when the carbon fiber is used as a heating wire core in the prior art, the introduced electric energy is converted into heat energy by 69 percent of the carbon fiber and is converted into far infrared rays by 30 percent of the carbon fiber for scattering, but the penetration rate of the existing cable insulation layer to the far infrared rays is not ideal, the far infrared rays are reflected and absorbed by the cable insulation layer, the far infrared rays heat the cable, but the far infrared rays are radiated to the outside to directly heat an external object, the fluorine rubber selected from the raw materials has high-quality heat shrinkability, and the silicon rubber can have certain high-temperature shrinkage performance by modifying the silicon rubber, so that the prepared high-temperature-resistant insulation layer generates a self-shrinkage phenomenon in a high-temperature environment and is tightly combined with the wire core, the heat emitted by the wire core is better conducted to the outside of the cable, and meanwhile, the transparency and the light transmittance of the silicon rubber are effectively improved by adding the silicon nitride and the white carbon black, the prepared high-temperature-resistant insulating layer has low reflection and absorption degrees on light radiation, the far infrared rays emitted by the wire core under the electrified condition are effectively promoted to be emitted to the outside, various heating devices prepared by utilizing the carbon fiber heating wire are directly used for heating an object to be heated, the loss between heat conversion is avoided, and meanwhile, the Arabic gum powder is selected by utilizing the high-quality adhesive force of the Arabic gum powder, so that the selected components are combined more tightly, and the prepared high-temperature-resistant insulating layer has stronger resistance to the high-temperature aging effect;
the preparation method of the high-temperature-resistant carbon fiber cable comprises the following steps:
s1: introducing silicon rubber, fluororubber, silicon nitride and Arabic gum into a high-speed shearing machine at normal temperature, controlling the rotating speed of the high-speed shearing machine to be 600-; the silicone rubber, the fluororubber, the silicon nitride and the Arabic gum are subjected to high-speed shearing and blending at normal temperature, the components are uniformly mixed while being crushed, and heating and melting are performed after the mixing is finished, so that the components in the prepared colloid are more uniformly mixed;
s2: controlling the temperature of the reaction kettle to rise to 220-240 ℃, then preserving the heat for 10-15min to prepare a pre-immersion liquid, spinning carbon fibers into threads, then passing through the pre-immersion liquid at a low speed, and rapidly cooling at a low temperature to prepare carbon fiber threads coated with modified silica gel, folding the carbon fiber threads, and collecting bundles to prepare a wire core; the fused mixture is subjected to heat preservation continuous treatment, the temperature in the mixture can be more uniform effectively, meanwhile, a layer of pre-immersion liquid is coated on the carbon fiber yarns, compared with the prior art, the carbon fiber yarns are directly used as wire cores, the pre-immersion liquid can fix the dispersed carbon fiber yarns in the carbon fiber yarns, and when the high-temperature-resistant insulating layer is used for coating, the pre-immersion liquid is dissolved so as to fill gaps in the carbon fiber yarns, so that the wire cores and the high-temperature-resistant insulating layer are combined more tightly, and the heat conduction rate is higher;
s3: sequentially adding glass fiber and stearic acid into the residual pre-immersion liquid in the S2, uniformly mixing and stirring the glass fiber and the stearic acid, introducing the mixture and the wire core into a single-screw extruder, controlling the extrusion temperature of the single-screw extruder to be 180 ℃ and 200 ℃, and coating and extruding the mixture to obtain a crude carbon fiber cable; adding glass fiber and stearic acid into the pre-immersion liquid, directly coating the pre-immersion liquid on the wire core in a coating extrusion mode to form a high-temperature-resistant insulating layer, melting the pre-immersion liquid coated on the wire core in the extrusion process, and further combining the pre-immersion liquid with the high-temperature-resistant insulating layer to enable the high-temperature-resistant insulating layer in the finally extruded crude carbon fiber cable to be more tightly combined with the wire core;
