The invention provides a multifunctional thermal insulation material and a preparation method thereof. The multifunctional thermal insulation material comprises a rigid thermal insulation material, a flexible thermal insulation material and fiber cloth, the flexible heat insulation material is located on the surface of the rigid heat insulation material, and the fiber cloth is used for wrapping the flexible heat insulation material and the rigid heat insulation material; a perforation structure is arranged on the rigid heat-insulating material, and fiber yarns are used for fixedly sewing the flexible heat-insulating material and the rigid heat-insulating material together through the perforation structure. The multifunctional thermal insulation material prepared in the invention not only has a lower heat conductivity coefficient, but also has better compression performance, so that the thermal insulation material can not only have better assembly performance, but also can dynamically adjust gaps between components during thermal insulation in a complex space, and the service life of the thermal insulation material is prolonged. And the heat insulation performance of the heat insulation material is fully exerted.

    本发明提供了一种多功能隔热材料及其制备方法,该多功能隔热材料包括刚性隔热材料、柔性隔热材料和纤维布;所述柔性隔热材料位于所述刚性隔热材料的表面,所述纤维布用于包裹所述柔性隔热材料和所述刚性隔热材料;所述刚性隔热材料上设有穿孔结构,纤维纱线通过所述穿孔结构将所述柔性隔热材料和所述刚性隔热材料缝合固定在一起。本发明中制备得到的多功能隔热材料不仅具有较低的导热系数,而且具有较好的压缩性能,使得隔热材料能够在复杂空间隔热时,不仅能够具有较好的装配性能,而且能够对构件之间的空隙进行动态调整,进而保证隔热材料充分的发挥隔热性能。
