Title:
COMPOSITE WALL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/178073
Kind Code:
A1
Abstract:
A composite wall material. The composite wall material comprises: a plant fiber layer as the outer layer, a waterproof layer as the inner layer, and a soundproof and thermal insulation layer arranged between the plant fiber layer and the waterproof layer. The plant fiber layer and the waterproof layer are connected therebetween using a connecting panel. The plant fiber layer is formed by randomly interleaving, hot-pressing, and gluing multiple strands of plant fibers. The plant fiber layer is fireproof-treated after being hot-pressed and glued. The composite wall material is of reduced density, of reduced weight, and of increased load-bearing capability, has increased waterproof and fireproof properties, and has a reduced heat transfer coefficient; also, because the plant fiber layer retains the increased with-the-grain mechanical strength of a plant, the composite wall material is provided with great strength and great toughness, thus enhancing the shock resistance of a building; furthermore, a thermal insulation material is provided within the soundproof and thermal insulation layer, thus allowing for thermal insulation and flame retardant effects while ensuring reduced weight.
