FIELD: chemistry.
SUBSTANCE: invention relates to fire-retardant silicone coatings meant for fireproofing cable factories having metal structures, ventilation ducts, including at atomic power plants and thermal power plants, as well as fire-resistant and moisture-protective finishing of industrial and building structures, including at atomic power plants and thermal power plants. The coating is obtained from a surface-bulk cold-setting composition which contains low-molecular weight siloxane rubber, low-molecular weight silanes, dibutyltin diacetate, ammonium polyphosphate and technical pentaerythritol, glased at defined ratios. The composition is prepared by bulk mixing of ingredients and is characterised by that the mixing process is supplemented with forced rubbing of granular ingredients in liquid siloxane rubber in a closed container with working volume ranging from 0.1 to 0.5 m3. Rubbing is carried out between movable blades and fixed legs, wherein the movable blades forcefully inject the composition into a grinding zone, thereby causing heating of the working mixture of the composition.
EFFECT: invention provides efficient fireproofing and corrosion protection of materials.
