Abstract

The invention discloses a high-temperature-resistant heat-insulation vibration-reduction composite material, which comprises a protective layer, an upper heat-insulation layer, a middle-low damping layer, a lower heat-insulation layer and a damping alloy layer sequentially arranged from top to bottom. The protective layer is glass fiber cloth, polyimide foam or silica gel fireproof cloth, the upper heat-insulation layer and the lower heat-insulation layer are both made of a silicon dioxide aerogel heat-insulation material, the middle-low damping layer is made of a viscoelastic damping material, and the damping alloy layer is made of a vibration-reduction alloy. The vibration-reduction composite material is light in weight, efficient, resistant to high temperature and irradiation, excellentin heat-insulation performance and high in vibration-reduction function; due to the structure, the problems of dust separation, material deformation caused by heating and vibration and the like are solved; during mounting, skin discomfort of workers cannot be caused, construction is convenient, and the composite material is more suitable for heat insulation of thermal equipment and pipelines of anuclear reactor system.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a high temperature resistant thermal insulation and vibration reduction composite material. Background technique [0002] When the nuclear reactor system is in normal operation, it is necessary to install thermal insulation materials on the outer surface of its high-temperature equipment and pipelines to reduce heat loss. Insulation materials for nuclear reactors not only need to have excellent heat insulation performance, radiation resistance performance, fire protection performance, etc., but also have a certain damping and vibration reduction function, so as to reduce instrument failure and noise transmission caused by thermal equipment pipeline vibration. [0003] The thermal insulation of existing nuclear reactor thermal piping systems generally adopts ultra-fine glass wool products or metal reflective insulation layers. Although ultra-fine glass wool has good he...
