Description

Sound insulation wall panel for building

technical field

The utility model relates to a building material, in particular to a sound-insulating wallboard for building.

Background technique

In the field of construction, wall panels are one of the most common building materials and are often used for non-load-bearing exterior walls or partitions of interior spaces. Wall panels were first made of perforated bricks or fly ash bricks. Due to their high construction strength, the construction site is easy to cause pollution, and the wall panels themselves have no functions such as heat preservation and sound insulation, which seriously affect the comfort of living. Later, gypsum board or polystyrene foam board was used. Although it is light in weight and easy to construct, its sound insulation and thermal insulation performance is not good. Especially when it is used as an external wall board of a non-load-bearing wall, due to faster heat transfer, the room is very hot in summer. It is very cold in winter; and for buildings located in noisy places, outdoor noise will also have a great impact. When used as an indoor partition wall, the sound partition effect between different rooms is very small, which affects the privacy of life.
