Effect of Pretreatment on Properties of Hemp-hurd-powder-filled Natural Rubber/Tyrene-butadiene Rubber Composites
摘要
Abstract
Hemp hurd powders (HP) were used as a type of waste bio-based fillers for the preparation of natural rubber (NR)/styrene-butadiene Rubber (SBR) composites,and the surfaces of HP were pretreated by means of several different methods before being used.The effect of pretreatment on curing characteristics,morphological structure,tensile properties,dynamic mechanical properties,abrasion resistance and fatigue resistance of NR/SBR composites was investigated.The results indicated that small-sized HP had litter influence on curing characteristics.Compared with pristine NR/SBR composites,the presence of HP led to an increase in tensile strength from 3.5 MPa to 10.6 MPa and an increase in tear strength from 22.9 kN/m to 32.9 kN/m.However,HP exhibited a negative effect on the abrasion and cyclic fatigue life of the composites.The pretreatments played an important role in improving physical properties of NR/ SBR composites,and furthermore,latex coagulation treatment was a better method than the coupling agent one.关键词
