Abstract
The scrap rubber powder (SRP) could be compression moulded to form elastomer via in situ interfacial reactions. In this study, SRP/NR (85/15) blends with good performance could be prepared by incorporating a little amount (lower than 5 phr of SRP and NR) of m-phenyl bismaleimide (BMI) in the compositions. The mechanical properties and the interface of SRP/NR (85/15, w/w) blends (base blend) were investigated. The results showed that the processing temperature, time, and BMI content have significant effects on the mechanical properties of the blends. The optimum BMI content and processing condition were determined as 5 wt.% and 180 ○C/10 min. The mechanical properties, especially the elongation at break, of the elastomers could be improved further by ultraviolet (UV) exposure. With UV exposure, the tensile strength, elongation at break and tear strength of the modified base blend were determined as 10.4 MPa, 260% and 24 KN/m respectively. The FTIR results indicated that the BMI could be grafted onto the SRP surface under UV exposure. The composition with UV exposure had more uniform dispersion of the BMI and improved interfacial adhesion. The glass transition temperature (Tg) of the blends was increased by increasing the processing temperature, processing time or the introduction of UV exposure.
