Composite insulation for buildings with excellent flame retardant and moisture-proof performance and improved energy efficiency
An objective of the present invention is to provide an interior and exterior composite insulation material for a building having quasi-noncombustible performance with excellent moisture-proof performance and flame retardant performance, which is equal to or more than the quasi-noncombustible performance, while maintaining thermal insulation performance by maintaining the initial thermal conductivity. The interior and exterior composite insulation material for the building with quasi-incombustible performance according to an embodiment of the present invention comprises: a first heat insulation layer formed of foam-styrene (EPS) and having quasi-noncombustible performance; a second heat insulation layer formed on the first heat insulation layer, including a nitrile butylene rubber (NBR) rubber foam insulation material and having quasi-noncombustible performance; and a flame retardant adhesive layer formed between the first heat insulation layer and the second heat insulation layer, wherein the NBR rubber foam insulation material includes, with respect to 100 parts by weight of NBR, 40 to 50 parts by weight of magnesium hydroxide, 1.5 to 4.0 parts by weight of sulfur, 1.5 to 3.5 parts by weight of adipic acid ester, 1.5 to 3.5 parts by weight of diamino diphenyl methane, 15 to 25 parts by weight of zinc oxide, 4 to 7 parts by weight of talc, 2.5 to 3.0 parts by weight of a foaming agent, and 8 to 15 parts by weight of a foaming aid. The NBR rubber foam insulation material has a thermal conductivity of 0. 034 W/mK or less and a moisture permeability coefficient of μ-value (mu-value) >= 10,000, and the flame retardant adhesive layer includes a chloroprene rubber adhesive.
