  • the chemical formula of vermiculite is M (Mg, Fe) (Si Al )0 x 6 1-x x 2
  • vermiculite contains 3 kinds of water: absorbed water, interlayer water and crystal water. It is known that : vermiculite can be fully hydrated at room temperature; between its layers, there exist two water layers and a trace of exchangeable ions; its interlayer distance is 14.2A. When heated, vermiculite expands like a leech by exfoliation-and-expansion phenomena due to pressure of water vapor generated in its crystal structure.
  • Vermiculite can expand about 6-fold to about 20-fold according to heating conditions and its quality. Expanded vermiculite, which exhibits low specific gravity and excellent thermal and acoustical insulation properties, is used as a thermal insulation material, an aggregate for light weight concrete and a sound-absorbing material. Besides, it is used as a filler for paper, plastic and paint, a mineral diluent, and a packing material.
  • expanded vermiculite has ever been used as neither a flame retardant nor an inorganic filler in making expandable polystyrene beads. Nevertheless, in the present invention, it has been found that moulded parts made from expandable polystyrene beads which contain expanded vermiculite powder exhibit excellent flame retardancy. Besides, it has been found that expanded vermiculite powder does not deteriorate expansion properties of expandable polystyrene beads nor other physical properties of expanded polystyrene beads. Further, since expanded vermiculite is much cheaper than conventional flame retardants such as expanded graphite, the present invention can realize a very economical preparation of expandable polystyrene beads with high flame retardancy.
