The utility model discloses a flexible sound insulation
blanket which comprises an
aluminum foil glass fiber cloth layer, a damping sound insulation felt layer and a
porous layer which are fixedly connected in sequence, and the
porous layer can be a
soluble fiber blanket or a SiO2
aerogel felt. The edge of the flexible sound insulation
blanket is provided with a groove, the flexible sound insulation blanket is connected with a hook-and-loop
fastener in a sewing mode, and a PVC thin plastic plate is arranged in the hook-and-loop
fastener. The
aluminum foil glass fiber cloth layer is composed of a soft
aluminum foil layer, an
adhesive layer and a
glass fiber cloth layer, and a heat-resistant
adhesive can be selected as an
adhesive. According to the flexible sound insulation blanket, through the synergistic effect of multiple
layers of materials, sound is effectively blocked and absorbed, and the sound insulation effect is remarkably improved. The flexible structure is convenient to install and can be attached to a complex surface, and the hook-and-loop
fastener and the PVC thin plastic plate are convenient to install, disassemble and maintain. The
composite material has wide application prospects in the fields of building,
industrial equipment noise reduction and the like, can meet the sound insulation requirements of different scenes, provides various
material selection and structure optimization schemes, and enhances the applicability and practicability of products.
