Cluster systems obtained by fractional dissolution of ultradispersed powders of metal salts (sodium, barium, calcium metavanadates) in active media such as dialkylphosphites are used as fire retardants of polymeric materials which contain functional groups. The control of the coordination reaction proceeding is carried out according to the color change (till painting stability). When cluster phosphorus-vanadium containing systems are introduced into olygomeric or polymeric compositions, the interaction of functional groups of polymeric component with the active centers of fire retardants of duster type occurs. As a result of such interaction the considerable increase of fire-resistant properties of the obtained polymeric materials is observed. The materials fire resistance is increased due to the stimulated carbonization proceeding in the surface layers. The scheme of stimulated carbonization process is suggested. This process consists in the dehydropolycondesation of aromatic hydrocarbons and is carried out in active media, containing metal ions or ultra dispersed metal powders. The result is the formation of carbon-metal containing nano-structures, having the defects due to the conditions of their extraction from the medium. |
