description The invention relates to the technical field of fluorosilicone rubber, in particular to an extruded fluorosilicone rubber compound and a preparation method thereof. The extruded fluorosilicone rubber compound comprises the following components in parts by weight: 100 parts of fluorosilicone raw rubber treated by perfluorooctyltrichlorosilane, 20-80 parts of hydroxyl fluorosilicone oil premixed white carbon black, 0.2-35 parts of a dispersing agent, 1-20 parts of calcium magnesium powder, 1-20 parts of lithium-based sepiolite, 0.5-10 parts of 3, 5-bis (trifluoromethyl) phenyl dimethyl silane, 1-20 parts of a heat-resistant additive and 0.2-5 parts of a cross-linking agent. Through application of different raw materials in the formula and a treatment process, excellent physical and mechanical properties of the fluorosilicone product are ensured, the bubble rate and the expansion rate in the fluorosilicone rubber compound extrusion processing process can be effectively reduced, and the production efficiency and
