MULTILAYER PRODUCT AND THE METHOD OF ITS MANUFACTURE (VERSIONS) Russian patent published in 2007 - IPC B32B15/95 B64C1/38 B32B7/02 B64D37/00 B64G1/00 

FIELD: rocketry; aircraft industry; method of manufacture of the multilayer product used at the cryogenic temperatures and/or in the condition of the aerodynamic heating.

SUBSTANCE: the invention is pertaining to the production technique of the multilayer products, which may be used in the fields of engineering, in which the products are working at the cryogenic temperatures and-or in the conditions of the aerodynamic heating. The product working at the cryogenic temperatures contains the metallic shell with the layer of the thermal insulation made in the form of the foam plastics. Between the metallic shell and the layer of the foam plastics there are the anticorrosive layer and the shock-absorbing layer. The foam plastics is additionally consolidated by the net installed with usage of the glue, and atop of it there is the antistatic coating. The product working at the cryogenic temperatures and additionally in the conditions of the aerodynamic heating contains the metallic shell with the layer of the thermal insulation made in the form of the foam plastics and the layer of the heat protection made out of the heat-protective coating consisting of the glue - Elastsil 137-180 and phenolformaldehyde microbeads (ТПШ-ЭС) deposited on the glue-hermetic, and atop of it there is the antistatic coating. The method of manufacture of the multilayer product consists that on the metallic surface they in series deposit the anticorrosive layer and the shock-absorbing layer, as the foam plastics they sputter Izolan-123 at the pressure of 0.4-0.6 mPa layerwise and then apply the glue-hermetic, overlay and then fix the molded cut sheets of the thermal-protective coating ТПШ-ЭС, age at the temperature of 15-35°С within 24 hours and atop of them deposit the antistatic coating - the enamel ХП-5237.

EFFECT: the invention ensures that the manufactured multilayer product is successfully working at the cryogenic temperatures and-or in the conditions of the aerodynamic heating.
