FIELD: technology for preparing heat building-up materials. ^ SUBSTANCE: invention relates to manufacturing heat building-up materials. Method for preparing heat building-up materials based on talc-magnesite involves preparing 30-60% an aqueous suspension of talc-magnesite by grinding talc-magnesite, its mixing with water, additional addition to the suspension 5-15 wt.-% of iron oxides, 0.5-4 wt.-% of water glass, 0.05-7 wt.-% of cement followed by treatment in cavitational device at the rotor rate 3000-12000 rev/min, at temperature 15-70°C and number of treatment cycles 5-50, and molding the prepared mass under pressure and its thermal treatment. Invention provides enhancing the specific heat value of talc-magnesite-base material. ^ EFFECT: improved preparing method, improved properties of materials. ^ 2 ex |
