In recent years, the plastic-wood processing industry has made great progress and has maintained a high annual growth rate, especially the application of outdoor flooring and building materials, which dominate the international plastic-wood composite material market. It is worth noting that the current molding methods of WPC are mainly extrusion, molding and injection molding. The pressure used in the processing process makes the density of this type of product usually larger, which is more than twice that of ordinary solid wood, so its own weight is larger. In addition, the interface compatibility between the hydrophilic wood fiber and the hydrophobic polymer in the plastic-wood composite material is generally low, resulting in the material’s mechanical properties such as impact strength and bending strength are often inferior to simple plastic products.

Foam Wood Plastic Composite Production Material

Foam Wood plastic composite (Foamd Wood plastic composite, FWPC) is a combination of plastic masterbatch, wood powder, filler, foaming agent and various additives in a certain proportion, and the foam is introduced into the wood plastic foam floor during the molding process. Made of holes. The gas-phase formed by the foaming agent in the plastic-wood blend phase system can be achieved through the separation of dissolved gases, the vaporization of volatile gases, or the release of gases produced by chemical reactions. The good cell structure inside FWP helps to passivate the crack tip in ordinary WPC and prevent crack propagation, so it can overcome the shortcomings of ordinary deep embossed decking such as greater brittleness, lower impact strength and lower material elongation. In addition, because FWPC contains a large number of cells and the material has large internal voids, the amount of resin used in preparation is greatly reduced, which reduces the cost of raw materials and effectively reduces the density of the material (about 50% of the unframed wood plastic foam floor material, Up to 0.6 ~ 1.0g/cm3), the sound insulation, heat insulation and cushioning effects of the material are also improved.

Foam Wood Plastic Composite Material Characteristics

In addition, because the foam material has a lighter weight and is easy to transport, construct and install, it is expected to become a substitute for wood and plastic used in the logistics and packaging industries. FWPC is also an environmentally friendly material, with a wide range of raw materials (both recycled secondary fibers and waste plastics), low manufacturing cost, and it can be recycled and reused many times, reducing the amount of plastic used, reducing environmental pollution, and It is beneficial to protect forest resources. Although some domestic packaging material manufacturers and research units are working hard to develop foamed pure plant fiber cushioning packaging materials, in comparison, FW-PC combines the advantages of wood and plastic, so it is still better in performance. It has advantages such as higher strength, better water resistance, lower price, and wider application range.

The current status of FWPC research has achieved many meaningful phased results. However, in the face of current market demand and a wider range of applications, it is necessary to further accelerate the industrialization of FWPC technology applications. For this reason, FWPC should continue to be Conduct in-depth and extensive research. The research and development of FWPC will receive closer attention and attention.
