Abstract

The present invention provides a thermal insulation sheet, and a method for preparing the thermal insulation sheet. Specifically, the thermal insulation sheet comprises a laminate of a plurality of sequentially stacked fiber layers, wherein: each of the plurality of fiber layers comprises an inorganic fiber, an adhesive fiber, and an inorganic filler particle, the adhesive fiber being melted so as to bond the inorganic fiber and the inorganic filler particle; and the thermal insulation sheet comprises a plurality of punching fixing portions penetrating through the thermal insulation sheet in a direction substantially perpendicular to a plane of the thermal insulation sheet. According to the technical solutions of the present invention, a thermal insulation sheet having good compression resilience properties, thermal insulation properties, and mechanical properties (e.g., tensile strength) can be provided.
