[Abstract] This invention provides a bamboo-scented particleboard and its manufacturing process. The bamboo-scented particleboard consists of an upper surface layer, a core layer, and a lower surface layer. The upper and lower surface layers are composed of the following raw materials: 2.1-5.5% MDI adhesive, 1.0-8.0% water-based tackifier, and the remainder being bamboo shavings. The core layer comprises the following raw materials: 2.1-5.5% MDI adhesive, 1.0-4.0% water-based tackifier, and the remainder being bamboo shavings. This invention also provides a production process for the above-mentioned bamboo-scented particleboard, including the following steps: material selection, shaving, drying, sorting, mixing adhesive, laying, hot pressing, cooling and curing, and sanding. The bamboo-scented particleboard provided by this invention can fully utilize bamboo, and the resulting board has no formaldehyde release. All its indicators are superior to the technical indicators specified by national standards.
[Sovereignty item] A bamboo-scented particleboard, characterized in that it comprises an upper surface layer, a core layer, and a lower surface layer bonded together. The thickness of the bamboo-scented particleboard is 2-40 mm. The bamboo-scented particleboard is made from the following raw materials through mixing, laying, hot pressing, cooling and curing, and sanding. The upper and lower surface layers are composed of the following raw materials, each with its mass percentage: MDI adhesive # 2.1-5.5%, water-based tackifier # 1.0-8.0%, and bamboo shavings with a thickness of 0.2-0.8 mm # balance. The core layer comprises the following raw materials, each with its mass percentage: MDI adhesive # 2.1-5.5%, water-based tackifier # 1.0-4.0%, and bamboo shavings with a thickness of 0.8-1.2 mm # balance. The mass ratio of bamboo shavings used in the upper and lower surface layers to those used in the core layer is 2-5:5-8.
