The research aimed to investigate the impact of processing parameters of wood-plastic composite on static bending strength in the mechanical property index.By applying the range analysis and variance analysis of the orthogonal experiment method,the main and subordinate influences of the processing parameters such as rotation speed,granular temperature,coupling agent mass fraction and wood powder content on the static bending strength of the mechanical properties index in the processing of wood-plastic composite were revealed,as well as the optimal level of each factor and the optimal combination of each processing parameter for the static bending strength of wood-plastic composite.In addition,the law of influence of various processing parameters on the static bending strength of the mechanical properties of wood-plastic composite was fully analyzed and illustrated.The results showed that the main processing factors,in the order of degree of effects from strongest to the weakest,which affected the static bending strength of wood-plastic composite were the mass percentage of coupling agent＞wood flour content＞rotational speed＞granulation temperature;The combination of processing parameters for wood-plastic composite to obtain the best static bending strength was that the rotational speed was 150 r/min,the granulation temperature was 145℃,the percentage of coupling agent was 5％,and the content of wood flour was 60％.The content of wood flour and the mass fraction of the coupling agent had a significant impact on the static bending strength of the material,the effect of rotation speed and granulation temperature on the static bending strength of the material was less significant.the static bending strength showed an obvious upward trend with the increase of the amount of coupling agent.The static bending strength of the material first increased and then decreased when the wood flour content increased from 30％to 70％.
