METHOD OF PRODUCING HEAT INSULATING FIREPROOF MATERIAL Russian patent published in 2014 - IPC C04B40/00 C04B28/30 

FIELD: chemistry.

SUBSTANCE: invention relates to production of building materials and can be used in making fireproof panels, partition walls, ceilings, doors and other structural components, used in construction of civil and industrial buildings in which fire and human safety is required. The method of producing heat insulating fireproof material involves mixing magnesia binder, filler and aqueous magnesium chloride solution, wherein the filler added to the magnesia binder is expanded vermiculite and optionally organic and/or mineral filler and mixing is carried out to obtain a homogeneous mixture of dry components, followed by mixing with aqueous magnesium chloride solution and optionally a plasticiser, moulding articles, drying and finish cutting, with the following ratio of components, wt %: magnesia binder 20-40, expanded vermiculite 1.5-15, aqueous magnesium chloride solution with density of 1.1-1.3 g/cm³ 45-70, organic filler 0-18, mineral filler 0-6, plasticiser 0-0.5.

EFFECT: high strength of the heat insulating fireproof material, simple implementation of the process and low power consumption thereof.
