The present invention relates to an insulating plate having flexibility, comprising 85 to 90 parts by weight of an acrylate emulsion, 20 parts by weight of ethylene glycol, 4 parts by weight of a dispersant, and melamine pyrophosphate. A first insulating layer having a thin film structure is formed through a first airgel composite paint comprising 30 parts by weight of a flame retardant, 10 parts by weight of an inorganic filler, 5 parts by weight of polyester fiber, and 1 part by weight of hydroxyethyl cellulose. wealth; 120 to 130 parts by weight of an acrylate emulsion, 20 parts by weight of ethylene glycol, 4 parts by weight of a dispersant, 30 parts by weight of a flame retardant prepared from melamine pyrophosphate, 10 parts by weight of an inorganic filler, polyester a second insulating part in which a second insulating layer having a thin film structure is formed through a second airgel composite paint comprising 5 parts by weight of fiber and 1 part by weight of hydroxyethyl cellulose; and a connection foam part made of phenolic foam having a thin film structure having a plurality of open holes opened up and down, the first insulating part being adhesively fixed on the lower surface and the second insulating part being adhesively fixed on the upper surface. . |
