▎ 摘　　要

NOVELTY - Thermal insulation floc containing aerogel includes a bottom skeleton fiber mesh layer, an aerogel thermal fiber mesh layer and a surface skeleton fiber mesh layer. The gram eight of the bottom skeleton fiber mesh layer is 30-300 g/m2, the thickness is 1-30 mm, the gram weight of the aerogel thermal fiber mesh layer is 40-120 g/m2. The weight of aerogel layer framework fibre net layer is 30-300g/m2, and the thickness is 1-30 mm. USE - Thermal insulation floc containing aerogel. ADVANTAGE - The thermal insulation floc containing aerogel achieves a substantial improvement in thermal performance through the addition of aerogel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the thermal insulation floc containing aerogel, which involves mixing the raw material fiber (A) and the low melting point fiber (B) in proportion and then opening, forming fibers after opening and mixing into uniform and dense mat cotton and carding into a web, processing into a quantitative fiber web composed of single fibers, and transporting to the subsequent process, folding and laying fiber web to the required width and thickness of the underlying skeleton fiber web layer, laying the aerogel thermal fiber net layer, turning on the negative air pressure adsorption device, so that the aerogel particles are uniformly adsorbed in the fiber net, until the required width and thickness are laid, laying the surface skeleton fiber mesh layer, and transporting the laid fiber mesh to the subsequent process, drying the fiber web, cooling and shaping the fiber net to obtain flakes, burning the surface of the flakes to make the surface of the product smooth, and trimming, counting, cutting and curling the flakes, and packing them into warm flakes.
