COMPOSITE MATERIAL THAT PROVIDES FOR MOTION OF TRANSPORT VEHICLE ON SLIPPERY SNOW OR ICE SURFACE, AND METHOD FOR ITS PRODUCTION Russian patent published in 2009 - IPC C09K3/14 

FIELD: transportation.

SUBSTANCE: invention is related to composite materials used for increase of friction coefficient between wheels of transport means and working surface, and may find application in motor, aviation, construction and other industries. Composite material is described, which provides for motion of transport vehicle on slippery snow or ice surface made of composition that contains wood chips in amount of 40-97 wt %, water solution of sodium chloride or calcium chloride or potassium chloride in amount of 1-30 wt %, 1-30 wt % of soot and 1-25 wt % of wollastonite, besides, average size of soot and wollastonite particles makes from 1 mcm to 250 mcm. Method is also described for production of composite material, which provides for motion of transport vehicle on slippery snow or ice surface. Method includes preparation of aqueous solution of sodium or potassium or calcium chloride, mixing of wood chips, soot and wollastonite in solution of sodium or calcium or potassium chloride, separation of suspension by filtration, drying of produced mixture at temperature of 80-150°C and packing of dried product.

EFFECT: improved friction properties between wheel of transport vehicle and slippery surface, elimination of slipping and wheel skidding on ice.
