Abstract

The invention discloses a sound-insulating and environmentally-friendly material for decoration and a preparation method thereof. The sound-insulating and environment-friendly material includes a hard sound-insulating layer, a sound-absorbing layer and a protective layer, wherein the sound-absorbing layer is arranged between the hard sound-insulating layer and the protective layer, and the hard The sound insulation layer is set on the side opposite to the internal space, and the protective layer is set on the side close to the internal space. The hard sound insulation layer has pressing protrusions to reduce further impact on the external space. At the same time, the pressing protrusions can reduce the wall Resonance with the hard sound-insulating layer; the sound-absorbing layer consists of two thin layers of foamed polypropylene and a laminated fiber layer arranged between the two layers of foamed polypropylene, and the protective layer is a foamed polypropylene sheet , the laminated fiber layer has small connected and tortuous holes, which can achieve a good attenuation effect on high-frequency noise, while the closed-pore structure of the foamed polypropylene sheet can isolate medium-low to medium-high frequency noise, thereby achieving broadband Noise isolation and absorption.

Description

technical field

[0001] The invention belongs to the technical field of environmental protection materials, and in particular relates to a sound insulation material for decoration and a preparation method thereof. Background technique

[0002] With the construction of urbanization, the density of residents continues to increase, and urban residents are increasingly affected by noise in their lives. In order to reduce the impact of noise on residents' lives, in addition to the use of noise-reducing cement in the construction of residential buildings In addition to concrete, building materials such as sound insulation glass can also have a good noise reduction effect when decorating. However, due to the limited construction scope of building materials such as multi-layer glass, in some areas with high noise, it plays Noise reduction is also limited.

[0003] The sound insulation effect of the improved space is to prevent internal noise from interfering with the external enviro...

Examples

Embodiment 1

[0041] A sound insulation and environmental protection material for decoration, comprising a hard sound insulation layer, a sound absorbing layer and a protective layer, wherein the sound absorbing layer is arranged between the hard sound insulation layer and the protective layer, and the hard sound insulation layer, the sound absorbing layer and the protective layer all pass through the sound insulation layer. The thickness of the hard sound insulation layer, sound absorption layer and protective layer is 3mm, 12mm and 4mm respectively. The hard sound insulation layer is set on the side opposite to the interior space, and the protective layer is set on the side close to the interior space. The hard sound insulation layer and the sound-absorbing layer are connected with pressing protrusions on the side opposite to the sound-absorbing layer. The pressing protrusions and the rigid sound insulation board are integrated into one structure. The height of the pressing protrusions is 2...
