Problems solved by technology

However, due to the large number of pits on the surface of aluminum foam, this method of direct gluing needs to consume a large amount of adhesive, and at the same time, many adhesives will release formaldehyde, which is not conducive to environmental protection
In addition, both sides of this composite material are rigid materials. In some scenes that need to be protected (such as kindergartens, nurseries, etc.), it is easy to bump into the rigid surface and cause injury.
At present, there is no composite material that is composited with flexible materials on the surface of aluminum foam.

Abstract

The invention relates to the technical field of building materials, in particular to a sound-insulation environment-friendly building material and a preparation method thereof. The sound-insulation environment-friendly building material comprises a flexible material layer and a foamed aluminum layer, wherein the flexible material layer is fixedly connected with the foamed aluminum layer by adopting a non-adhesive; the foamed aluminum layer is made of open-cell foamed aluminum with the average pore diameter of 6-12 mm; the flexible material layer is non-woven fabric, geotextile, woven fabric and the like of which one side is attached with a Velcro rough surface; and a double-sided hook surface buckle belt is attached to the surface of the foamed aluminum layer. According to the invention, the sound-insulation environment-friendly building material has the advantages of light weight, sound insulation, electromagnetic shielding and the like, meanwhile, the surface is made of a flexible material, a certain protection effect can be achieved, the sound-insulation environment-friendly building material can be widely applied to building sound insulation, house decoration, sound insulationwallboards and the like, and the application range and scenes of the foamed aluminum material are greatly expanded.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sound-insulating and environment-friendly building material and a preparation method thereof. Background technique [0002] With the development of society, the urban population is increasing day by day, and more and more people live in high-rise buildings. As population density increases, so does the noise. Outside of tall buildings, cars shuttle around every corner of the city. The difference in work and rest time between households in the residential area, the sound of the square dancing lady, the hawking of the vendors, etc., will all make various noises. Therefore, when building a house and decorating a house, it is particularly important to isolate noise. There are many measures to prevent and control noise, the simplest is to remove the noise source. However, most of the noise is almost impossible to remove, such as the noise of cars passing by, which will...
