Background technique

Due to the improvement of people's living standards, people pay more attention to the quality of life, and the requirements for the acoustic environment of living, working and living are constantly improving.

With the continuous advancement of China's urbanization process and the increase of population density, land resources have become more precious. Due to the continuous improvement of construction technology and the continuous development of building materials and construction technology, more and more multi-storey and high-rise buildings have been developed. A large number of buildings adopt reinforced concrete structures, and are developing towards high-rise buildings and large bays. With the development of building structures, a large number of lightweight wallboard materials are applied to building enclosure walls and partition walls. The application of lightweight wallboard materials reduces the load on the structure, saves steel and cement, reduces the cost of the project, increases the usable area inside the building, and is easy to install. In order to achieve a good effect of sound absorption and insulation, a large number of thick wallboards are currently used, occupying a large use area; and once light and thin wallboards are used, the sound insulation performance will be difficult to meet the requirements.

For example, the Chinese patent authorization announcement number: CN203905280U, the date of authorization announcement is October 29, 2014, which discloses a light-weight fireproof, thermal insulation and sound insulation wall panel, including: a first panel, a second panel, sound-absorbing thermal insulation material and a light steel keel The sound-absorbing and heat-insulating material is arranged between the first panel and the second panel of the frame, and the sound-absorbing and heat-insulating material is fixed between the first panel and the second panel through the light steel keel frame. In this patent, the manufacturing process of the wallboard is complicated and the material cost is relatively high.

Utility model content

Aiming at the technical defects of existing fire-proof and sound-insulating panels, the utility model provides a new type of fire-proof and sound-insulating panels with excellent sound insulation and noise reduction performance, which can achieve high sound insulation and fire prevention effects in a small thickness scale. The manufacturing process is simple and the material cost is low.

The purpose of this utility model is to provide a fire-proof and sound-insulating board, which includes surface layers located on both sides of the board, a middle sound-insulating layer between the surface layers, a fire-proof layer between the middle sound-proof layers, the surface layer and the middle A lightweight sandwich layer is filled between the sound insulation layers and/or between the middle sound insulation layer and the fireproof layer, the surface layer and the middle sound insulation layer are made of sound insulation materials or composite sound insulation materials, and the lightweight sandwich layer is made of absorbent The fireproof layer is made of fireproof material, the middle soundproof layer is a corrugated board, and the crest or trough of the corrugated board is connected to the surface layer, and the fireproof layer is arranged between the middle soundproof layers.

Preferably, the fireproof layer is a fireproof board arranged between the middle sound insulation layers.

Preferably, the fireproof layer is filled between the middle sound insulation layers.

Preferably, the material used for the surface layer and the middle sound insulation layer is silicate material or gypsum material or metal material or polymer material or their combination, and the material used for the lightweight sandwich layer is porous sound-absorbing material or fiber cotton Sound-absorbing material or expansion material, the material used for the fireproof layer is fireproof material.

The fire-proof and sound-insulating board provided by the utility model has excellent sound-insulating and sound-absorbing performance, and at the same time has good fire-proof effect, simple and reasonable structure, high strength, light weight, thin volume, environmental protection, convenient installation and use, simple manufacturing process and low cost. Low.
