The invention relates to a preparation method of a high-strength TPU composite thermal insulation fabric, and belongs to the technical field of textile fabrics. In the technical solution of the present invention, the structural properties of the material are improved by adding hollow microspheres inside the sol material between the TPU film and the matrix fiber layer. On the one hand, the prepared composite hollow microspheres exhibit a hexagonal close-packed spatial distribution. , such a dispersed structure is conducive to the formation of a stable structure inside the material and improves the bonding strength between materials, thereby effectively improving the bonding strength and mechanical properties of the material. Further improvement, effectively improving the thermal insulation performance of the material. |
