The invention discloses a functional heat preservation bag and a preparation method thereof. The heat preservation bag comprises an interlayer bag body and a filler filled in the interlayer of the interlayer bag body. The interlayer bag body includes the following raw materials in parts by weight: Base rubber, polyisobutylene, nano-calcium carbonate powder, phenolic resin, ultrafine aluminum hydroxide, silicon carbide whiskers, plasticizer and antioxidant; the filler includes the following raw materials by weight: polyurethane resin, chitosan Sugar, sodium bisulfite, far-infrared nano powder, nano silver powder, calcium powder, porous carbon microspheres. The functional thermal insulation bag of the present invention is composed of selected raw materials, optimized the content of each raw material, and selected an appropriate ratio, which not only gives full play to their respective advantages, but also complements and promotes each other. The prepared functional thermal insulation bag has excellent Toughness and high temperature resistance, and has excellent thermal insulation properties. |
