Embodiment 1
[0081] The raw materials for the preparation of the wood-plastic base material include: 60 parts of HDPE plastic, 20 parts of wood fiber, 4 parts of coupling agent, 10 parts of inorganic filler, 3 parts of lubricant and 3 parts of melt reinforcement in proportion by mass. Preparation methods include:
[0082] S1. Extrusion of wood-plastic parison: Put the raw materials used for the preparation of wood-plastic substrates into the mixer in turn and mix them evenly, and then use the granulator to make wood-plastic granules, and put the wood-plastic granules into the screw extruder. After conveying, melting and plasticizing, mixing and homogenizing and pressurizing and compacting, a square wood-plastic parison with a length×width of 100.0mm×100.0mm is extruded from the molding die mouth;
[0083] S2. Surface pre-cooling: The wood-plastic parison extruded from the forming die is pre-cooled through a cooling die. The temperature of the cold water in the cooling die is set at 80°C. A...

[0088] A three-dimensional reinforced and toughened wood-plastic composite material with on-line braided pipe network and its preparation method. The composite material is composed of hemp fiber pre-tensioned pipe network near the body surface and wood-plastic base material. The raw materials for the preparation of wood-plastic substrates include: proportioned in parts by mass, 60 parts of PVC plastic, 10 parts of wood fiber, 4 parts of interface compatibilizer, 10 parts of inorganic filler, 3 parts of lubricant, and 3 parts of melt enhancer , 6 parts heat stabilizer and 4 parts antioxidant. Preparation methods include:
[0089] S1. Extrusion of wood-plastic parison: Put the raw materials used for the preparation of wood-plastic base materials into the mixer in turn and mix them evenly, then put the raw materials into the one-step wood-plastic extruder, convey them through the screw, and melt and pre-plasticize , After melting and plasticizing, mixing and homogenizing and pre...
