Abstract

The invention relates to the technical field of three-dimensional spacer fabrics, and discloses an aerogel-filled three-dimensional spacer fabric. The aerogel-filled three-dimensional spacer fabric comprises 20-30 parts of flame-retardant fibers, 10-20 parts of aerogel fibers, 10-20 parts of phase-change fibers, 10-15 parts of shape memory fibers and 3-5 parts of anti-static liquid. By adding theaerogel fibers, the fiber aerogel is directly added into other fibers to be blended together to prepare the three-dimensional spacer fabric, so that the step that the aerogel is directly added into the three-dimensional spacer fabric is omitted, and the binding property of the aerogel and the three-dimensional spacer fabric is better; the flame-retardant fibers, the phase-change fibers and the shape memory fibers are added, so that the flame-retardant capacity of the three-dimensional spacer fabric can be improved through the flame-retardant fibers, and through the phase-change fibers, when the environment temperature is higher than a certain threshold value, the material absorbs heat through phase change and has the refrigerating effect; and when the environment temperature is lower thana certain threshold value, the material is subjected to phase change heat release and has a heat preservation effect, so that the temperature around the fibers is controlled, and the temperature of the three-dimensional spacer fabric is adjusted.

Description

technical field [0001] The invention relates to the technical field of three-dimensional spacer fabrics, in particular to an airgel-filled three-dimensional spacer fabric and a preparation method thereof. Background technique [0002] With the development of society, people have higher and higher requirements for high temperature resistant materials and heat insulation materials in the field of thermal protection. At present, various high temperature resistant filling materials are widely used, such as alumina, zirconia and silica, etc. Nano-powder and airgel materials, people try to use silica airgel and various heat-resistant fibers to prepare airgel composite materials, but the mechanical properties of loose fibers are poor, and the interface between airgel and fibers The binding effect is weak, so the mechanical properties of the obtained airgel composites are limited. [0003] Patent No. CN201810033459.X discloses a method for preparing an airgel-filled fabric, which i...
