Problems solved by technology

[0004] By searching the existing literature, it can be seen that the existing thermal insulation materials are mainly plastics, and their mechanical strength is poor.
Although fiber-reinforced thermal insulation materials have good mechanical properties and excellent fire resistance, the existing production process requires long curing time, low production efficiency, and high energy consumption

Description

technical field [0001] The invention belongs to the technical field of insulating material manufacturing, and in particular relates to an environment-friendly, flame-retardant, heat-conducting and insulating fiber-reinforced composite material and a manufacturing method thereof. Background technique [0002] Existing fiber-reinforced insulating materials are usually produced by the following processes: lamination, molding, pultrusion, winding and other composite molding. However, when producing products with large thickness or large size, due to the low thermal conductivity, it takes a long time for molding and curing, so that the production process consumes a lot of energy, has low efficiency, and is prone to the problem of incomplete center curing. [0003] After retrieval, Chinese patent documents disclose the following patent documents related to thermally conductive insulating materials: Publication No. CN101333434A A thermally conductive insulating material and its man...
