(2) mixing acrylonitrile and tert-butyldimethylsilyl chloride according to the mass ratio of 20:1, heating to 55 ℃, and keeping the temperature for 15min to obtain a mixture;
(3) adding the mixture into the wood powder mixed solution according to the mass ratio of 1:15, adjusting the pH value of a reaction system to 5.5, adjusting the temperature to 86 ℃, stirring for 2 hours at the rotating speed of 120r/min, then filtering, cleaning by using deionized water, and drying in vacuum to constant weight to obtain the wood powder mixed solution.
Further, the wood flour is eucalyptus wood flour.

Compared with the prior art, the invention has the following advantages: according to the invention, through modification treatment on the polyvinyl chloride resin, the apparent viscosity of the melt of the modified polyvinyl chloride resin and acrylonitrile modified wood powder composite material can show a trend of obvious reduction along with the increase of the shear rate, so that the characteristic of shear thinning is shown, and a typical pseudoplastic fluid behavior is shown. This is because when the shear rate is increased, the entanglement points between the macromolecular chains of the modified polyvinyl chloride resin are disentangled, the disentanglement rate of the entanglement points is greater than the reconstitution rate, the number of the entanglement points is reduced, and the relative movement between the macromolecules of the modified polyvinyl chloride resin is easier, so that the apparent viscosity is also reduced. On the other hand, when the shear rate is increased, the molecular segments of the modified polyvinyl chloride resin are oriented in the flow field without being as much as possible to relax and shrink, so that intermolecular interaction between flow layers is reduced, and the flow resistance is lowered. Therefore, the processing stability is greatly improved in the processing process; the interface of the composite material is bonded most strongly through the synergistic effect between the modified polyvinyl chloride resin and the acrylonitrile modified wood powder, and when the composite material is acted by external force, the external force can be uniformly transmitted to the reinforced fibers through the interface, so that the external force is effectively buffered among the reinforced fibers, and the mechanical property of the composite material is improved accordingly; according to the invention, the eucalyptus wood powder is modified by acrylonitrile, and the acrylonitrile monomer and the eucalyptus wood powder are selected because a great deal of experimental research shows that the modification effect of the acrylonitrile monomer on the eucalyptus wood powder is the best, in the modification process, the grafting rate of the acrylonitrile monomer on the surface of the eucalyptus wood powder can be fast and stable, and in the modification process, the surface of the eucalyptus wood powder is grafted with more active points, so that the initiated active centers are increased, the surface performance of the wood powder modified by acrylonitrile is obviously improved, the compatibility between the wood powder and polyvinyl chloride molecules is obviously improved, meanwhile, the acrylonitrile modified wood powder is more uniformly dispersed in a complex system, the physical and mechanical properties of the composite material can be effectively improved, particularly, the impact strength is obviously improved, and meanwhile, the water absorption of the wood-plastic foam material can be effectively reduced.
