CONSTRUCTION MATERIALS BASED ON GYPSUM WITH HIGH HEAT CONDUCTIVITY AND ATTENUATION DURING SHIELDING Russian patent published in 2010 - IPC C04B28/14 C04B111/92 

FIELD: chemistry.

SUBSTANCE: invention relates to construction materials based on gypsum, containing ground compact expanded graphite from intercalated graphite compounds in amount of 5-50%, preferably maximum of 25%, in terms of dry mass of the construction material, as well as to a method of producing said construction material involving the following steps: obtaining an intercalated graphite compound, thermal expansion of the intercalated graphite compound to form expanded graphite, compressing the expanded graphite to form a two-dimensional structure with thickness of 0.1-3 mm, preferably a maximum of 1 mm, and density of 0.8-1.8 g/cm³, grinding the obtained compacted expanded graphite and addition of the obtained ground mass to the gypsum-based construction material. The invention also pertains to an article moulded from the said construction material and a method of making said moulded article, as well as to use of the said moulded article. The invention is developed in subclaims of the formula of invention.

EFFECT: high heat conductivity and strong shielding from electromagnetic radiation.
