Abstract

The thermal insulation material of the embodiment of the present invention comprises: a first layer comprising nanoporous foam; a second layer comprising microporous foam having pores larger than the aforementioned nanoporous foam on the first layer; and a third layer comprising The above-mentioned second layer contains expanded graphite.

Description

technical field [0001] The present invention relates to heat insulating materials, and more particularly, to heat insulating materials with improved laminated structures. Background technique [0002] Various heat insulating materials are used to improve the heat insulating performance of buildings and the like. The most widely used heat insulating material of this type is a heat insulating material composed of a foam formed by foaming a resin. [0003] However, in this way, a heat insulating material composed of foamed resin is limited in that it can realize heat insulating performance only by itself, so it is difficult to ensure sufficient heat insulating performance. Therefore, a heat insulating material capable of realizing sufficient heat insulating performance is required. Contents of the invention [0004] technical problem [0005] The present invention provides a heat insulating material having excellent heat insulating properties. [0006] solution to the pro...
