The invention discloses a kind of wood plastic composite, make: 1%～70% modified wood powder, 25%～99% polymeric matrix and 0～5% processing aid by following raw materials by weight percent.The invention also discloses the preparation method of this wood plastic composite, adopt the silicon fluoride coupling agent that the wood powder surface is handled, modified wood powder and polymeric matrix are carried out the compound preparation wood plastic composite of fusion, and wood powder carried out pre-treatment with alkali lye, Unstable Substances such as the hemicellulose in the removal wood powder, small molecular ester, strengthened composite effect and the mechanical property of lignocellulose to polymeric substrate, make the low and apparent preferably pattern of good mechanical performance, water-intake rate, and the preparation method is simple to operate, is suitable for suitability for industrialized production. |
