Summary:The invention belongs to the technical field of building materials, and discloses a low-shrinkage inorganic thermal insulation material based on modified dura fibers as well as a preparation method and application of the low-shrinkage inorganic thermal insulation material. According to the low-shrinkage inorganic thermal insulation material based on the modified dura fibers, the modified dura fibers are doped into foam concrete (FC), and the modified dura fibers and ultra-high performance concrete (HTIC) form a combined component, so that under the dual reinforcement effect and on the premise that the volume weight of the material is not excessively increased, on one hand, the defect that the foam concrete is low in strength is greatly overcome; the 28d compressive strength can reach 16 to 18MPa, the breaking strength can reach 6 to 8MPa, the bending-compression ratio reaches 0.4 to 0.5, and the toughness is obviously improved; on the other hand, the shrinkage rate is effectively reduced, and the early-stage
