Beschreibung
Zusammenfassung:	The invention discloses a high-temperature fire-resistant flange gasket which is prepared from the following components: 20-30 parts by weight of inorganic fiber; 40-60 parts by weight of a fire-resistant filler; 1-10 parts by weight of an inorganic binder; 0.1 to 1 part by weight of a flame retardant; 3-10 parts by weight of an organic binding agent; 0.01 to 0.1 part by weight of an auxiliary agent A; 1-10 parts by weight of an auxiliary agent B; and 1-5 parts by weight of an auxiliary agent C. In addition, the invention further discloses the high-temperature fire-resistant flange gasket and a preparation method of the high-temperature fire-resistant flange gasket. The high-temperature fire-resistant flange gasket is free of asbestos, environmentally friendly, high in classification temperature and capable of being used as a flange sealing gasket at high temperature. In addition, according to the preparation method of the high-temperature fire-resistant flange gasket, a wet process is adopted for preparation
