研究了不同加工温度（200、220和240°C）对未涂覆和环氧树脂涂覆的铬鞣革废料-ABS复合材料的热性能和机械性能的影响。结果表明，复合材料的力学性能随加工温度的升高而降低。与未涂覆的皮革废料-ABS复合材料（LWABS）相比，环氧树脂涂覆的皮革废料纤维-ABS复合材料（CLWABS）具有更好的力学性能。这些结果是在200°C的优化处理温度下获得的。场发射扫描电子显微镜（FESEM）的研究证实了这一结果。差示扫描量热法（DSC）研究表明，环氧树脂涂覆的皮革废弃物纤维（CLW）显示出比未涂覆的皮革废弃物纤维（LW）更高的起始温度和熔融温度，分别为131.8 ° C和179.35°C，未涂覆的皮革废弃物纤维（LW）的玻璃化转变温度（Tg）和熔融温度（Tm）分别为128.2 ° C和169.4°C。当LW和CLW纤维与丙烯腈丁二烯苯乙烯（ABS）混合时，发现CLWABS复合材料的Tg和Tm分别为94.9和269.8°C，高于LWABS复合材料的Tg和Tm分别为89.1和261.6°C。因此，这项研究表明，利用环氧涂层铬鞣皮革废弃物纤维作为ABS基复合材料的设计中的填料将有助于解决我们的环境中的固体废物污染物的问题。
The effect of varying processing temperatures (200, 220 and 240°C) on the thermal and mechanical properties of uncoated and epoxy-coated chrome-tanned leather wastes-ABS composites has been studied. The results obtained showed that the mechanical properties of the composites decreased as the processing temperature increased. Epoxy-coated leather wastes fibre-ABS (CLWABS) composite yielded better mechanical properties compared to the uncoated leather wastes-ABS composite (LWABS). These results were obtained at an optimized processing temperature of 200°C. Furthermore, the results were confirmed by the field emission scanning electron microscopy (FESEM) studies. The differential scanning calorimetry (DSC) studies revealed that the epoxy-coated leather wastes fibres (CLW) showed higher onset and melting temperatures of 131.8 and 179.35°C than the uncoated leather wastes fibres (LW) with glass transition (Tg) and melting (Tm) temperatures of 128.2 and 169.4°C, respectively. When the LW and CLW fibres were mixed with Acrylonitrile butadiene styrene (ABS), the Tg and Tm of CLWABS composite were found to be 94.9 and 269.8°C, respectively, higher than the LWABS composite with Tg and Tm of 89.1 and 261.6°C, respectively. Thus, this study has demonstrated that utilization of epoxy-coated chrome-tanned leather wastes fibres as fillers in the design of ABS-based composites will help a great deal in addressing the problem of solid waste pollutants in our environment.
