Abstract

The invention discloses an environment-friendly composite partition board, belonging to the technical field of building materials. The environment-friendly composite partition board comprises surfacelayers on two sides and a sandwich layer in the middle, perforated plates are respectively arranged on two sides of the sandwich layer, barriers are arranged around the perforated plates, air layers is formed among the barriers, the perforated plates and the sandwich layer, corrugated plates are arranged in the air layers, multiple layers of non-woven fabrics are paved on the outer side of the perforated plates, and the surface layers on two sides of the sandwich layer vertically communicate. By improving the structure, the material and the preparation process of the partition board, the soundabsorption performance of the product is excellent.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to an environment-friendly composite partition wall board and a preparation method thereof. Background technique [0002] Partition wall panels are prefabricated panels used for interior partition walls, mainly used for office or home interior partitions. Traditional partition boards are mainly reinforced concrete boards or gypsum boards, which have high strength and high fire resistance, but are heavy in weight, inconvenient for construction, and poor in sound insulation. The lightweight partition board has the characteristics of light weight, environmental protection, sound insulation, and heat preservation, and can meet people's requirements for the building environment. Its materials are mostly fibers, concrete, and polymer materials. [0003] Chinese patent announcement number CN106927779B discloses a nano-fireproof partition board and its manufacturing method. The ...
