Foamed Wood Plastic Composite Decking Development Trend
Foamed wood plastic composite decking material has the advantages of low cost, light weight, high strength, heat preservation and sound absorption, etc., the market demand and application field will be larger and larger, but the existing products can not meet the demand, so it is necessary to conduct in-depth research on product design and process realization, so as to realize the industrialization of foamed WPC composite material. In recent years, foamed wood plastic composite deck has become a hotspot in the field of wood-based materials and polymers.
Overall, the current research of wood plastic foam floor mainly from “foaming mechanism”, “surface modification”, “plastic types” and “enhanced fiber” and “molding process” direction analysis of foamed wood plastic composite flooring “material composition”, “molding process, and the relations between and among the structure performance, so as to improve performance of foamed wood plastic composite products.
Significant progress has been made in the research of foamed WPC decking composites at home and abroad, and a series of important research results have been obtained to promote the sustainable development of the WPC industry.
The research trend of foamed wood plastic composites deck will focus on the following aspects.
New Foaming WPC Decking Technology
The existence of foam can overcome the inherent defects of wood-plastic composites and improve the properties of materials. New foaming processes such as supercritical fluid injection molding will be the focus of future research. To improve the interfacial compatibility of WPC, the interfacial compatibility is an important factor that restricts the application of WPC, and the foamed WPC, the existence of foam pores weakens the connection between plastics and fibers. Although coupling agents used at present can improve the interfacial compatibility, there is still room for improvement.
Outdoor Decking Functional Material
In order to expand the application scope of foamed wood-plastic decking panel, the development of materials with sound insulation, anti-corrosion, flame retardant, aging resistance, creep resistance and other functions is the next research and development focus.
Garden WPC Decking Has High Fibre Content
Biomass fiber, as a renewable resource, is more energy-efficient and environmentally friendly than plastic, with a lower price. Adding fiber components in foamed wood-plastic composites can not only reduce the cost, but also accelerate the degradation of materials. But increasing the amount of fiber must make foaming more difficult, some properties of the material will also be reduced. Therefore, the improvement of fiber content will be the future research direction.
With the increasing shortage of resources, people’s demand for WPC decking composites will increase day by day, which also puts forward higher requirements for the preparation technology of WPC composites. In the future, foamed WPC decking composites will also develop towards the direction of product functionalized and diversified.
Foamed wood plastic composite decking materials have excellent cost performance and good specific strength, and the addition of additives can endow it with more properties, so it has been applied in many industrial fields. High-performance micro-foam WPC composites are used in the automotive and aerospace industries to process components with high strength and light weight. The biggest application is the high performance and light weight wood plastic compound material of co-extrusion floor building products, which will have a great application in the automotive interior decoration and doors and Windows market.
