FIELD: disguise.
SUBSTANCE: invention relates to a camouflage heat-insulating coating, having infrared invisibility and incombustibility, used for surfaces of various nature and shape, used in various industries and construction, including for the production of clothes, fabrics, raincoats, which protect against electromagnetic waves, which block the visual thermal background in the infrared range from the surfaces of various heated articles, objects, machines, equipment, vehicles, as well as those used as camouflage of moving objects, masses and bodies. Masking incombustible heat-insulating coating contains a base and a heat-insulating layer in the form of an incombustible ultrathin heat insulation with flammability group “Non-combustible”, which is applied on one or both sides to the base, with a thermal conductivity coefficient of 0.001 W/(m⋅°C), based on hollow microspheres with thickness of 1 to 4 mm, made from a water-suspension composition with viscosity of 1 to 100 Pa⋅s, including a mixture of polymer binder 5-95 vol.% with hollow microspheres 5-95 vol.%, as a polymer binder, the composition contains a water-based polymer latex composition, as hollow microspheres, the composition contains microspheres with different sizes from 10 to 500 mcm and different bulk density from 50 to 650 kg/m3, which absorb the magnetic component of radar radiation, wherein the aqueous suspension composition additionally contains a mixture of a polyatomic alcohol with a polybasic carboxylic or amino acid in an equimolecular ratio, as well as a fire retardant.
EFFECT: obtaining an elastic non-combustible light heat-insulating coating, which enables to reduce the thermal background in the infrared range of electromagnetic waves from heated surfaces without complicating the design and increasing the thickness of the material, as well as with the possibility of painting in different colours without deterioration of thermophysical properties.
