Abstract:

A flame-retardant polymer composite material characterized in that the composite material comprises a substrate (50) comprising a polymer material such as a resin and, dispersed therein or attached to the surface thereof by coating or the like, composite particles (10) for imparting flame retardancy which forms, upon heating, a glass-like ceramic containing oxides of silicon and/or a metal as main components; a composition for producing the flame-retardant polymer composite material; and a formed product of the flame-retardant polymer composite material. When the flame-retarded material is heated to a high temperature, compounds in composite particles (10) for imparting flame retardancy form, due to heat, a protective film hindering the material from burning, and as a result, the flame-retarded material can acquire, at a low cost, a high flame retardancy, for example, a flame retardancy satisfying the level of V-0 to V-2 according to UL94 flammability test. The formation of a protective film also allows the provision of satisfactory flame retardancy to the flame-retarded material by incorporation of a small amount of the compounds in the composite particles.
