摘要
Abstract
Taking MAH as grafting monomer, HEA as comonomer, polypropylene was modified with melt grafting technology; and then taking MAH/HEA/PP as compatibilizer, the effect of compatibilizer on structure and properties of PP/glass fiber composites were investigated. The results show that MHA and -OH group has been grafted onto PP by comparison with the un-grafted PP, and the melt-grafting reaction has obvious effects on melt point and thermal stability of the grafted PP. Additionally, the mechanical properties of PP/glass fiber composites improves with the increasing of grafted PP content. When the content of the grafted PP is 15%, the tensile strength and impact strengthen of the composite increase by 32% and 13% respectively. The melt-grafted PP has good compatibilization, coupling and dispersion effect.关键词
