Abstract

The invention belongs to the technical field of composite thermal insulation materials, and particularly relates to a carbon fiber thermal insulation material and a preparation method thereof. The carbon fiber thermal insulation material is formed by uniformly distributing carbon fibers and phenolic resin fibers, wherein the carbon fibers and the phenolic resin fibers are connected through a graphitization process after being subjected to spinning, pressurizing, curing and forming. The technical problems that an existing carbon fiber thermal insulation material is complex in component, poor inthermal insulation effect, tedious in production process and serious in process pollution are solved. The carbon fiber thermal insulation material provided by the invention is simple in component, lower in cost, better in heat preservation effect, higher in compression strength, controllable in shrinkage, simplified in technological process and stable in structure, and a felt body formed by blending and spinning the fiber carbon fibers and the phenolic fibers is formed at a time.

Description

technical field [0001] The invention belongs to the technical field of composite heat insulation materials, and in particular relates to a novel carbon fiber heat insulation material and a preparation method thereof. Background technique [0002] In response to the country's call to reduce process environmental pollution and save material resources. In the process of carbon fiber composite material preparation, the environmental pollution in the preparation process is reduced and the quality of the working environment of employees is improved. Concentrated multi-stations are carried out at the same time, which reduces production costs, shortens production time, and improves product controllability. It is the development direction of many composite materials enterprises. [0003] However, the existing carbon fiber heat insulating material has complex components, high production cost, poor heat insulation effect, and its preparation process has many procedures, serious proce...
