<p>As a kind of renewable resources, timber has been an important material for the national economy since ancient times. However, as a single material, timber has obvious defects such as low absolute strength, poor rigidity, corrosion, flammability and cracking. The occasion is limited. At the same time, there are a large number of wood chips that can not be used in the processing of wood. Wood-plastic composite materials are wood fiber or plant fiber as the main component, after pretreatment with thermoplastic resin or other composite materials made of a new material. This material takes into account the dual characteristics of plant fiber and plastic, durable, long life, higher than the plastic hardness, better than wood stability, and has good processing of thermoplastic, easy to shape.</p>
<p>Another prominent advantage of wood-plastic material is the material can be reused or recycled, while biodegradable. Wood-based materials used in the wood powder bamboo powder, wood flour, rice husk powder, peanut shell powder, these materials are rich in resources, cheap, easy to get. Wood-plastic materials because of both plant fiber biodegradability, renewable, it is considered a very promising green materials.</p>
<p>However, the ordinary wood-plastic material limit oxygen index (LOI) is low, about 18 or so, are flammable materials, in some high temperature or flammable occasions or have a larger security risk. With the popularization of the concept of safe plastic, wood-plastic material processing security, the use of security as a trend.</p>
