SILICON-BASED POLYURETHANE COMPOSITIONS Russian patent published in 2015 - IPC C04B26/16 C04B28/26 C04B111/20 C04B111/28 C04B111/40 

FIELD: chemistry.

SUBSTANCE: claimed group of compositions provides polyurethane silicon-based compositions. Polyurethane silicon-based composition is obtained by means of reaction of ingredients, containing polyisocyanate, aqueous silicate and alumosilicate to be hydrated, selected from metakaolin, fly ash and their mixtures, polyol and optionally inert filling agent. Method of obtaining said compositions contains stages of mixing alumosilicate to be hydrated with aqueous silicate and reaction of said mixture with polyisocyanate and/or polyisocyanate prepolymer optionally in presence of polyol and/or with introduction of inert filler. Application of said compositions as fireproof light materials with high mechanical loading for seats, wings, interior upholstery, steering wheel, door panel, encasing of luggage compartments and components of engine room, lamellar constructions, heat-insulating panels, bearing loading of roofing coverings and systems of covering, systems of repairing bridges and roads, stationary and mobile cooling units, insulating inflammation of materials, mattresses and upholstery fabric, building panels and systems of outer insulating covering, bearing high load in-situ of packing building elements with double walls.

EFFECT: obtaining fire-resistant light materials with high mechanical loadings.
