Ultrahigh-temperature heat-insulating composite material and preparation method thereof
The invention provides an ultrahigh-temperature heat-insulating composite material and a preparation method thereof. According to the invention, a multilayer structure with a form of Z-G-Q-Z is adopted, wherein the Zs are high-temperature-resistant fibrous textile fabrics; the G is a flexible high-temperature heat-insulating layer; the Q is a low-medium-temperature heat-insulating layer; the multilayer structure is sutured into a whole through a high-temperature-resistant suture line; the flexible high-temperature heat-insulating layer is a fiber mat which is molded from high-temperature-resistant fibers and an infrared barrier agent with an inorganic sol as a high-temperature binder according to a wet method; and the low-medium-temperature heat-insulating layer is a fiber-reinforced aerogel material. According to the invention, the flexible high-temperature heat-insulating layer is compounded with the low-medium-temperature heat-insulating layer and the high-temperature-resistant fibrous textile fabrics are sutured on the upper and lower surfaces of the compounded layers, so the material has the advantages of high-temperature resistance, highly-efficient heat-insulation performance and excellent anti-vibration and anti-shock properties.
