MOULDING COMPOSITION FOR SLAB MATERIALS FOR PROTECTIVE AND STRUCTURAL PURPOSE AND METHOD OF PREPARING SAID COMPOSITION Russian patent published in 2011 - IPC C08L97/02 B27N3/00 

FIELD: chemistry.

SUBSTANCE: moulding composition contains an aggregate made from carbon-containing crushed plant and/or synthetic fibre material, binder made from inorganic polymers and a target additive. The inorganic polymers used in the composition are metal phosphates with aluminium, chromium, boron and magnesium cations and anions РО₄ ^--- or metal silicates with sodium, potassium and lithium cations and with anions SiO₃ ^--, pre-modified with solutions of organic bases with an amide bond and/or oxides or trihydrates of aluminium oxide or mixtures thereof. The target additive is a water repellent or hardener or surfactant. The aggregate, working solution of the binder and target additive are prepared first. The aggregate is treated with the working solution, dried and moulded into briquettes.

EFFECT: ecologically clean, non-toxic, non-combustible slab materials which are resistant to aggressive media are obtained.
