specific Embodiment approach 1
[0036] Specific embodiment 1: a kind of hollow microsphere particle board with vacuum tube inside described in this embodiment, its component and weight percent are:
[0037] Wooden raw materials: 75%~90%;
[0038] Hollow microspheres: 4%~20%;
[0039] Vacuum tube: 4%~20%;
[0040] Coupling agent: 0.5%~4%.
[0041] The technical effect of this embodiment is: by improving the components of the particleboard so that the hollow microspheres and vacuum tubes play a role in the particleboard, the average density of the particleboard can be reduced while forming a closed vacuum environment inside the particleboard, so that the particleboard has a better sound insulation effect.
specific Embodiment approach 2
[0042] Specific Embodiment 2: Combining figure 1 and figure 2 Describe this embodiment mode, a kind of hollow microsphere particleboard with built-in vacuum tube described in this embodiment mode, the woody material and the hollow microspheres together form a woody material layer, and the hollow microspheres are evenly distributed in the woody material layer Scattered, the wooden raw material layer has at least two layers, and the vacuum tube 7 is arranged between the wooden raw material layer and the wooden raw material layer; the others are the same as in Embodiment 1.
[0043] The technical effect of this embodiment is that further dispersing the hollow microspheres inside the board on the basis of the vacuum tube inside the board plays an important role in further reducing the density of the board and improving the heat and sound insulation performance of the material.
specific Embodiment approach 3
[0044] Embodiment 3: Combining figure 1 , figure 2 and image 3Describe this embodiment mode, a kind of hollow microsphere particleboard with built-in vacuum tube described in this embodiment mode, there are multiple vacuum tubes 7, and each vacuum tube 7 is not connected; the coupling agent is an isocyanate coupling agent; other Same as Embodiment 1.
[0045] The technical effect of this embodiment is: the unconnected vacuum tubes function independently, and when the vacuum tubes are multi-layered, the overall performance of the board is better; the use of isocyanate coupling agents can carry out covalent chemical reactions with the hydroxyl groups in the wood raw materials, The bonding strength between wood raw materials and between wood raw materials and hollow microspheres is increased; in addition, no harmful gases such as formaldehyde are released during use, and the prepared particleboard is green and environmentally friendly.
