The present invention relates to a refractory composition, and more particularly, by mixing an epoxy resin and an acrylic resin to form a binder resin, a refractory material capable of improving the fire resistance of a high-pressure container repeatedly exposed to contraction and expansion, and to low and high temperatures. It relates to the composition. The refractory composition according to the present invention is based on 100 parts by weight of a binder resin in which an epoxy resin and an acrylic resin are mixed, 100 to 300 parts by weight of a flame retardant, 30 to 100 parts by weight of a foaming agent, 200 to 150 parts by weight of expanded perlite, and an anti-scattering agent. 3 to 50 parts by weight, and 20 to 40 parts by weight of an epoxy curing agent based on 100 parts by weight of the epoxy resin, and 1 to 10 parts by weight of an acrylic curing agent based on 100 parts by weight of the acrylic resin. |
