摘要

为研究偶联剂对木粉、废旧橡胶和塑料组成的木橡塑三元混合物料流动性能的影响,分别采用3%、5%、8%的马来酸酐接枝聚乙烯(MAPE)和0.5%、1%、3%、5%的橡胶专用硅烷偶联剂(Si69)对三元混合物料进行表面处理。结果表明:两种偶联剂对复合物料体系的流变特性均具有显著影响,且二者之间存在显著的交互作用; 单独使用MAPE,其质量分数在5%时混合物料的剪切应力和表观黏度值最小,加工性能最优; MAPE和Si69同时使用时,混合体系的流变性以MAPE质量分数和Si69质量分数均为3%的配合为最佳。

Abstract

To investigate the influence of coupling agents on the flow performance of wood/rubber/HDPE mixed raw materials in manufacture of composites, maleic anhydride grafted polyethylene(MAPE)and silane coupling agents(Si69)were applied to modify the interface of the wood/rubber/HDPE composites. The adding amount of MAPE were 3%, 5% and 8%, and Si69 was 0.5%, 1%, 3% and 5%. The results showed significant influences of the two coupling agents on the rheological properties of the mixed raw materials and significant interactive effects between the two kinds of coupling agents. With 5% MAPE used alone, the mixed materials showed minimum shear stress and apparent viscosity, which means an optimal processing performance. When used together, 3% MAPE and 3% Si69 were proved to be the best combination.
