Methods for Improving WPC Compatibility of Composite Interfaces

WPC is the abbreviations of Wood Plastic Composite. WPC board is a mixture of reclaimed wood, recycle plastic and a small amount of adhesive. Now it becomes an ideal building material for residential and commercial use. Combines the advantage of different materials, WPC boards are more sturdy and durable than real wood, but also possesses a similar appearance of the real wood. With our unique installation method, there are no nails or screws on the floor surface, it’s more secure and convenient for cleaning and maintenance.

Lign material is mainly composed of cellulose, hemicellulose and lignin, which is a non-uniform and anisotropic natural polymer composite, which contains a variety of extracts and other components, so the interface characteristics are very complex. because cellulose, hemicellulose and lignin etc contain a lot of polarity. Therefore, in the development of wood fiber-plastic composites, the biggest problem needs to be solved is how to make the interface between hydrophilic polar wood surface and hydrophobic non-polar plastic substrate have good compatibility. Thus, the surface layer of wood material and plastic surface layer can achieve intermolecular fusion, resulting in better performance than the original single material. In order to achieve this goal, a lot of research work has been carried out in this field at home and abroad.
