In order to improve the regenerative WPC (RWPC) interface compatibility Based on the wood fibers with different surface treatment method, with high density polyethylene (HDPE) melt blending important of composite woodextrusion granulation prepared RWPC carried out tensile, bending, impact melt index and other performance tests, scanning electron microscopy (SEM) to observe the tensile and impact fracture morphology of the sample.

The results showed that: three methods alkali treatment, coupling treatment and alkali / coupling composite processing can effectively improve the tensile properties RWPC,price of recyclable woodflexural and impact properties. Base coupling composite treatment has a synergistic effect of the alkali treatment and coupling treatment, is the most effective surface treatment method.SEM fracture surface analysis showed that after the base coupling composite processing, wood fiber and improve the interface compatibility of HDPE to improve the interfacial adhesion, so that the performance has been improved RWPC.

In order to further improve the overall performance RWPC, the paper will RWPC respectively regeneration powder, glass fibers melt blending, extrusion granulation, and carried out the performance test. The results show that:outside decking floor with the increase of the amount of renewable powder, impact strength RWPC upward trend, breaking elongation ratio increased without adding regeneration powder, the tensile strength decreased. After comprehensive comparison of results when regeneration powder content of 15% and a particle size of 120 mesh, RWPC has the best performance; in RWPC system, the addition of glass fiber reinforced RWPC have some effect, when the glass fiber content when 4%, RWPC strong ...
