摘要

A flame-retardant polymer composite material characterized in that the composite material comprises a substrate comprising a polymer material such as a resin (i.e., a material to be flame-retarded) and, dispersed therein or attached to the surface thereof by coating or the like, composite particles (10) for imparting flame retardancy having a structure wherein a carrier particle (1) is combined with a layer (2) of compounds containing a silicon component and/or a metal component and oxygen; a composition for producing the flame-retardant polymer composite material; and a formed product of the flame-retardant polymer composite material. The flame-retardant polymer composite material can impart high flame retardancy to a material to be flame-retarded at a low cost, since, when the flame-retarded material is heated to a high temperature, the layer (2) forms a protective film hindering the material from burning, and the formation of a protective film allows the provision of satisfactory flame retardancy to the flame-retarded material by incorporation of a small amount of the compounds of the layer (2), which results in reducing the amount of a retardant including the above composite particles.
