Deicing heat-insulating coating on the basis of hollow microspheres

摘要

Deicing heat-insulating coating made from an aqueous suspension composition with a viscosity of 1 to 100 Pa.s, comprising a mixture of polymeric binder 5-95 vol.% With a base of 5-95 vol.%, As a polymeric binder composition comprises water-based polymer latex composition, containing from 10 to 90 vol.% (co) polymer selected from the group consisting of a homopolymer of an acrylate, styrene-acrylate copolymer, styrene-butadiene copolymer, polystyrene, butadiene polymer, polyvinyl chloride polymer, polyurethane polymer, the polymer or a copolymer of vinyl acetate or mixtures thereof and from 10 to 90 vol.% mixture of water and a surfactant, wherein as filler a mixture of hollow glass microspheres with a diameter of 10-500 microns with a bulk density of 50-750 kg / mi hollow polymeric vakuomizirovannyh microspheres and hollow polymeric microspheres have a diameter of 10-90 microns and a bulk density of 25-40 kg / m, taking 5-95 vol.% aqueous slurry composition further comprises a mixture of a polyhydric alcohol with a polybasic carboxylic acid or an amino acid in an equimolar relation ns, while as the base composition comprises a bulk density varying from 650 to 50 kg / m, porous airgel particles which have an arbitrary shape, porosity in excess of 60%, a density less than 0.6 g / cc, a diameter of from 10 to 500 micrometers formed on the basis of metal oxides, e.g., alumina, or silica-based or consisting of trialkyl hydrophobic surface groups and / or triarylsilyl, and / or phenyl, and / or trimethylsilyl, with the following ratio of components, in parts by weight:
