Abstract
(EN)
A thermal insulating material and a refrigerator. The thermal insulating material comprises transparent monolithic aerogels packaged by a protective film. The protective film comprises: a single layer of high-density polyethylene, medium-density polyethylene, low-density polyethylene, linear low-density polyethylene, or unstretched polypropylene having a thickness greater than 30 µm and less than 50 µm; or a laminate comprising high-density polyethylene, medium-density polyethylene, low-density polyethylene, linear low-density polyethylene, or unstretched polypropylene having a thickness greater than 30 µm and less than 50 µm, and biaxially stretched polypropylene, biaxially stretched nylon, or polyethylene terephthalate having a thickness greater than 12 µm and less than 28 µm. Therefore, characteristics of transparent aerogels are exerted to provide a transparent thermal insulating layer.

La présente invention concerne un matériau isolant thermique et un réfrigérateur. Le matériau isolant thermique comprend des aérogels monolithiques transparents conditionnés par un film protecteur. Le film protecteur comprend : une seule couche de polyéthylène à haute densité, de polyéthylène à moyenne, de polyéthylène à basse densité, de polyéthylène linéaire à basse densité, ou de polypropylène non étiré qui a une épaisseur supérieure à 30 µm et inférieure à 50 µm; ou un stratifié qui comprend du polyéthylène à haute densité, du polyéthylène à basse densité, du polyéthylène linéaire à basse densité ou du polypropylène non étiré qui a une épaisseur supérieure à 30 µm et inférieure à 50 µm, et du polypropylène étiré biaxialement, du nylon étiré biaxialement, ou du polyéthylène téréphtalate qui a une épaisseur supérieure à 12 µm et inférieure à 28 µm. Donc, des caractéristiques d'aérogels transparents sont exercées pour fournir une couche isolante thermique transparente.
