Embodiment 1

[0047] Please refer to image 3 , this embodiment is a flow chart of using waste carbon fiber as a raw material to manufacture a composite thermal insulation material. It can be seen that it mainly includes the following steps:

[0048] A manufacturing method of using waste carbon fiber to make a composite thermal insulation material, comprising:

[0049] S201: Surface treatment, crushing and dispersion of waste carbon fiber raw materials;

[0050] Carbon fiber is made by spinning, and the short carbon fiber is cut or crushed according to a preset length through a special tool (such as a gantry knife) or a gas crusher. Of course, in order to better combine with auxiliary materials, before preparing chopped carbon fibers, it is necessary to perform surface treatment on carbon fibers according to different auxiliary materials to improve the performance of composite materials.

[0051] If necessary, it is also necessary to put the treated chopped carbon fiber into the grinder f...

Abstract

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 glass, heat treatment, aerospace, steel, electric power, solar energy, semiconductor and other industries where equipment needs insulation, and are mainly used in the shell of the furnace. However, with the expansion and popularization of the product application range, the performance and structure requirements of the furnace equipment are becoming more and more stringent and complex, including higher processing temperature, higher processing purity, larger volume, Less weight, higher power and other technical advantages. For example, in the manufacturing process of electronic, electrical components or high-power optical devices, larger...
