Embodiment 1
[0015] A heat-preservation, fire-proof and sound-absorbing panel for indoor suspended ceilings, comprising a fire-proof decoration layer 1, a flame-retardant and sound-absorbing layer 2, a heat-insulating layer 3 and a reinforcing glue layer 4 in sequence from outside to inside.
[0016] Wherein, the fireproof decorative layer 1 is a fireproof melamine decorative paper with a thickness of 1-3 mm, wherein the surface of the fireproof melamine decorative paper has uniform outward convex points.
[0017] The flame-retardant and sound-absorbing layer 2 is an expanded vermiculite layer with a thickness of 2-5 cm.
[0018] The insulation layer 3 is a polyurethane foam layer with a foam density of 0.6-0.8kg / m 3 , and its thickness is 1 to 2 times the thickness of the flame-retardant sound-absorbing layer 2 .
[0019] The reinforcing adhesive layer 4 is a glass fiber cloth layer impregnated with environmentally friendly glue, with a thickness of 1-3 cm.

Abstract
The invention discloses an indoor furred ceiling insulation fireproof acoustic panel comprising a fireproof decorative layer, a flame retardation sound-absorbing layer, an insulation layer and a reinforcing glue layer which are successively composited; the flame retardation sound-absorbing layer is made of an expanded vermiculite layer; the reinforcing glue layer is a glass fabric layer. The provided indoor furred ceiling insulation fireproof acoustic panel has simple structure and reasonable design; by means of the expanded vermiculite, the sound absorption performance and the fire protecting performance of the whole board are increased; the insulation fireproof acoustic panel has high integral structure intensity, excellent insulation, fireproof and sound absorbing performance, and broad market prospect.
Description
technical field [0001] The invention relates to the field of sound-absorbing panels, in particular to a heat-preserving, fire-proof and sound-absorbing panel for indoor suspended ceilings. Background technique [0002] Sound-absorbing panels refer to plate-shaped materials with sound-absorbing and noise-reducing effects, which are mainly used in theaters, concert halls, museums, exhibition halls, libraries, interrogation rooms, galleries, auction halls, gymnasiums, lecture halls, multi-functional halls, and hotel lobbies Hospitals, shopping malls, schools, piano rooms, conference rooms, studios, recording studios, KTV rooms, bars, industrial plants, computer rooms, home noise reduction and other places that require high acoustic environment and high-end decoration. [0003] Most of the existing fire-proof and sound-absorbing panels have the disadvantages of easy deformation due to moisture absorption, unsustainable sound-absorbing performance, and poor fire-proof and heat-in...
