Preparation method of high-temperature-resistant heat-insulating carbon felt, prepared heat-insulating carbon felt and application of heat-insulating carbon felt
The invention discloses a preparation method of a high-temperature-resistant heat insulation carbon felt, and relates to the technical field of heat insulation materials. The preparation method comprises the following steps: 1) in a vacuum or inert gas atmosphere, performing carbonization treatment on polymer foam to obtain a prefabricated soft carbon felt, wherein the polymer foam is melamine foam or polyurethane foam; and 2) putting the prefabricated soft carbon felt into a chemical vapor deposition furnace to deposit pyrolytic carbon so as to obtain the high-temperature-resistant heat-insulation heat-preservation carbon felt. The invention also provides the heat-insulation carbon felt prepared by heat-insulation carbon felt. The preparation method has the beneficial effects that the process of preparing the prefabricated soft carbon felt is simple, then the prefabricated soft carbon felt is put into the chemical vapor deposition furnace to deposit pyrolytic carbon, and carbon grids of the soft carbon felt are wrapped by the pyrolytic carbon, so deflection and expansion of cracks are effectively hindered, the service life of the prefabricated soft carbon felt is prolonged, and the mechanical properties of the heat-insulation carbon felt are improved; and the heat-insulation carbon felt provided by the invention can be applied as a heat-insulation material to various heat-insulation furnaces.
本发明公开一种耐高温隔热保温碳毡的制备方法，涉及保温隔热材料技术领域，本发明包括以下步骤：1)在真空或惰性气体氛围下，将聚合物泡沫进行碳化处理，得到预制软碳毡，所述聚合物泡沫为三聚氰胺泡沫或聚氨酯泡沫；2)将所述预制软碳毡放入化学气相沉积炉中沉积热解炭，得到所述耐高温隔热保温碳毡。本发明还提供采用上述方法制得的保温碳毡及其应用。本发明的有益效果在于：本发明将制备预制软碳毡的工艺简单，之后预制软碳毡放入化学气相沉积炉中沉积热解炭，使热解炭将软碳毡的炭网格包覆起来，有效阻碍裂纹的偏转和扩展，延长了预制软碳毡的使用寿命，并提升了保温碳毡的力学性能，本发明保温碳毡可作为保温材料用于多种保温炉中。
