Today, with the increasing sensitivity to environmental issues, bio-based materials are needed as an alternative to traditional materials. Rosin is used for bio-material production due to its abundance in nature and being cheap. This study aims to produce bio-epoxy using powdered rosin with enhanced mechanical properties. Powdered rosin was used at 1, 3, 5 wt.% to study the effect of additive ratios. Three different mixing methods were used to make the mixture homogenous. A magnetic stirrer was used in the first method, an ultrasonic stirrer was used in the second method, and both were used in the third method. The bio-epoxy was successfully synthesized, and mechanical properties were examined by tensile, compression, density, and hardness tests. As a result, it was determined that the best mixing method was the third mixing method and the best results in additive ratios were obtained at 1 wt.% for tensile strength (5.63%) and hardness (14.41%), and at 5 wt.% for compression strength (8.28%).

具有改善的机械性能的松香粉生物基环氧树脂

如今,随着对环境问题的日益敏感,需要生物基材料来替代传统材料。松香由于其性质丰富且价格便宜而被用于生物材料生产。这项研究旨在使用具有增强的机械性能的松香粉生产生物环氧树脂。以1、3、5 wt。%的量使用松香粉来研究添加剂比例的影响。使用三种不同的混合方法使混合物均匀。在第一种方法中使用磁力搅拌器,在第二种方法中使用超声波搅拌器,并且在第三种方法中均使用超声波搅拌器。成功地合成了生物环氧树脂,并通过拉伸,压缩,密度和硬度测试检查了机械性能。结果是,
