FIELD: chemistry.
SUBSTANCE: invention relates to field of aviation and space technology, mainly, to production of heat-proofing coatings, which can be applied for application on external or internal surface of envelopes from silicon nitride of antenna nose cones of rockets. Heat-proofing coating, includes, wt %: silica filler 36-58; alumoborophosphate binding agent 30-34; Al2O3·3SiO2 1-10; Al2O3·2SiO2 1-10; sodium oxide 1-2, magnesium oxide 1-2; aluminium oxide 1-3; silicon nitride 1-2; boron oxide 2-3; boron nitride 1-3.
EFFECT: increase of heat resistance, heat-proofing properties of products under conditions of exposure to intensive thermal and mechanic loads without changing dielectric characteristics.
