FIELD: composite materials.

SUBSTANCE: invention relates to a method for producing a block composite material for gas accumulation. Method includes the stages of mixing the components with a binder, shaping the resulting mixture into blocks, and subsequently drying said blocks. The method is characterised by using an organometallic coordination polymer and a nanoporous carbon adsorbent or an adsorbent based on carbon nanotubes as components, wherein said components are mixed in a proportion from 30/70 to 95/5 wt.%; the effective inner diameters of the micropores of the mixed components differ by at least 0.4 and no more than 0.8 nm; a 2 to 15% aqueous solution of compounds selected from polyvinyl alcohol, a solution of chitosan in acetic acid, and oxy-ethyl cellulose, is used as a binder. The resulting mixture is shaped under a press into blocks for 1 to 2 minutes with a loading force of 25 to 75 kN, the blocks are placed in a drying chamber under normal conditions, followed by raising the temperature at a rate of no more than 60 deg/h to 110–120 °C and drying the blocks for at least 12 and no more than 36 h, then activating in a thermal vacuum chamber at 120 °C for at least 6 h at a residual pressure of up to 0.26 kPa. Invention also relates to a block composite material.

EFFECT: possibility of increasing the bulk density of the block composite material by moulding while preserving the developed inner surface, increasing the hardness of the resulting block composite material, and reducing gas losses caused by temperature and pressure fluctuations in the gas storage system.
