| titleOfInvention | Graphite/silicon carbide heat-insulating backing and preparation method thereof |
| abstract | The invention provides a graphite/silicon carbide heat-insulating backing and a preparation method thereof. The graphite/silicon carbide heat insulation backing is composed of solid bodies and relatively loose pore parts, the size of all pores is controlled to be less than phi 1mm, and the pores are isolated and dispersed, and the volume ratio of the pores does not exceed 20% (as shown in figure 1). The preparation method comprises the following steps: firstly preparing graphite/phenolic resin mixed powder, then preparing a graphite/silicon carbide heat-insulating backing blank by using a selective laser sintering molding technology, and finally obtaining the graphite/silicon carbide heat-insulating backing by carrying out secondary curing, vacuum pressure impregnation of phenolic resin solution, carbonization, vacuum pressure impregnation of silica sol, high-temperature hot-pressing sintering and other processes. The method has the characteristics of high material utilization rate, no dust pollution, low production cost, controllable comprehensive performance and the like. The prepared graphite/silicon carbide heat insulation backing has low density, high compressive strength, high temperature resistance, low heat conductivity coefficient and good heat insulation effect. |
