COMPOSITE MATERIAL WITH INCREASED ADHESION FORCE, METHOD OF ITS PRODUCTION AND APPLICATION, IN PARTICULAR, IN CIGARETTE FILTERS Russian patent published in 2011 - IPC B01J20/10 B01J20/16 B01J20/20 B01J20/26 A24D3/06 

FIELD: technological processes.

SUBSTANCE: invention relates to a composite material with higher force of adhesion made of at least one polymer and at least one compound selected from silicon dioxide and activated coal, at the same time the specified composite material has the following: average particle size of at least 100 mcm, porous volume (Vd1), formed by pores with diameter from 3.6 to 1000 nm, of at least 0.2 cm³/g, force of adhesion such that content of particles in it with size of less than 100 mcm, produced under air pressure of 2 bar, makes less than 1.5 vol. %, is preferably equal to 0.0%. Also a method to produce a composite material is described, as well as its usage as a liquid medium carrier, a catalyst carrier, an additive or for filtration of liquid or gas, in particular, in cigarette filters.

EFFECT: invention provides for high properties of hazardous components reduction in filtered medium.
