The present invention includes a first heat insulating layer, a second heat insulating layer, and a third heat insulating layer, one side of the first heat insulating layer is in contact with one side of the second heat insulating layer, and one side of the second heat insulating layer is the third heat insulating layer. It is in contact with one side of, and the first heat insulating layer and the third heat insulating layer are made of polyester, viscose rayon, nylon, polypropylene and poly lactic acid. It includes one or more non-woven fabrics, the second insulation layer includes airgel made of biomass, and the biomass is an eco-friendly insulation material of alginate or alginic acid. it's about The present invention provides an eco-friendly insulator, which can minimize the amount of carbon generated in the disposal process using biomass, which is a natural waste, and can provide an eco-friendly insulator with improved insulation rate and improved flame retardancy. |
