A long-term temperature-resistant and low-radiation heat-proof jacket and its manufacturing method

Abstract

The invention discloses an insulated sleeve with long-term temperature resistance and low radiation. The insulated sleeve is provided with an insulated sleeve bottom layer made of a high-temperature insulated fabric; the high-temperature insulated fabric is provided with an overlapping edge at the corner of an instrument; the external surface of the high-temperature insulated fabric is coated with a continuous insulated coating layer; a ceramic fiber fabric is glued at the exterior of the insulated coating layer; the external surface of the ceramic fiber fabric is also coated with a continuous insulated coating layer, and the exterior of the insulated coating layer and the end surface of the insulated sleeve are sprayed with lacquer coatings; aluminum foil composite insulated films are glued at the exteriors of the lacquer coatings. A manufacturing method of the insulated sleeve comprises the following steps: manufacturing the insulated sleeve bottom layer by use of the high-temperature insulated fabric, painting an insulated coating, and baking for solidification; gluing the ceramic fiber fabric, painting an insulated coating on the outer surface of the ceramic fiber fabric, and baking for solidification; spraying varnish on the exterior of the insulated coating layer and the end surface of the insulated sleeve, and baking for solidification; and gluing the aluminum foil composite insulated films on the lacquer coatings. The insulated sleeve is convenient to install, good in molding cooperation and stable in protection effect.

Description

technical field [0001] The invention relates to a heat-proof cover for instruments, meters and other equipment on an aerospace vehicle under the technical state of long-term temperature resistance or low radiation heat flow and a manufacturing method thereof. Background technique [0002] At present, most of the heat-resistant materials used for long-term temperature-resistant and low-radiation aerospace instruments and instrumentation equipment are protected by multi-layer wrapping. This technology has the disadvantages of inconvenient tooling, poor molding fit, The protection effect is unstable and other shortcomings. The wrapping method mostly uses high-temperature heat-insulating cloth for 1 / 2 wrapping method, which is relatively time-consuming, and will generate excess material and increase weight during winding. During the flight, heat-resistant materials in special parts exist at a certain frequency. loose risk. Contents of the invention [0003] The technical pro...
