Embodiment 1
[0046] Please refer to figure 2 This embodiment is a flow chart of using waste carbon fibers as raw materials to manufacture composite thermal insulation materials. It can be seen that it mainly includes the following steps:
[0047] A manufacturing method of using waste carbon fiber to make composite thermal insulation material, including:
[0048] S201: Surface treatment, crushing treatment and dispersion treatment of waste carbon fiber raw materials;
[0049] The carbon fiber is made by spinning, and the short carbon fiber is cut or crushed according to a preset length by a special cutter (such as a gantry guillotine) or a gas crusher. Of course, in order to better combine with the auxiliary materials, before preparing the chopped carbon fiber, the surface treatment of the carbon fiber should be done according to different auxiliary materials to improve the performance of the composite material.
[0050] If necessary, it is also necessary to put the treated chopped carbon fiber i...

The invention provides a compound thermal insulation material manufactured by using waste fibers and a manufacturing method of the compound thermal insulation material and is applied to the field of insulation materials on a high-temperature furnace body. The compound thermal insulation material comprises basic materials and auxiliary materials, wherein the basic materials are waste fiber raw materials and are fiber raw materials which can be carbonized after being subjected to high-temperature calcination, the auxiliary materials comprise graphite, an adhesive and resin, and the waste fiber raw materials comprise one or multiple of polypropylene fibers, asphalt fibers, viscose, pre-oxidized fibers, phenolic fibers, carbon fibers, graphite fibers, wood fibers and cotton fibers. The compound thermal insulation material manufactured by adopting the materials according to the method have relatively thin fiber diameters, relatively small heat conductivity coefficient, relatively good ablation resistance and relatively good purity; and as the compound thermal insulation material is manufactured by using the waste fibers, the cost is reduced, and the benefits and the product competitive power of enterprises are increased.
Description
Technical field [0001] The invention relates to the application of a composite thermal insulation material, in particular to a composite thermal insulation material made of waste fibers and a processing and manufacturing method of the composite thermal insulation material. Background technique [0002] Insulation materials are widely used in the fields of glass, heat treatment, aerospace, steel, electric power, solar energy, semiconductor and other industries that require insulation, and are mainly used in furnace shells. However, with the expansion and popularization of product applications, the performance and structure requirements of furnace equipment are becoming more and more stringent and more complex, including requirements for higher processing temperature, higher processing purity, larger volume, Lighter weight, higher power and other technical advantages. For example, in the manufacturing process of electronic, electrical components or high-power optical devices, larg...
