摘要
在可持续发展背景下,以可再生资源开发高性能材料至关重要。以丁香酚单体、1,1,3,3-四甲基二硅氧烷、环氧氯丙烷为主要材料,合成了一种生物基环氧树脂前驱体,并通过1H-NMR对其进行结构表征。使用γ-缩水甘油醚氧丙基三甲氧基硅烷(KH560)对六方氮化硼进行了表面改性处理,并将其加入生物基环氧树脂前驱体中制备了一种生物基环氧复合材料。与纯生物基环氧树脂相比,添加质量分数2%的BN-KH560的复合材料的摩擦系数由0.711降低至0.498,拉伸强度由25.92 MPa增加至29.82 MPa。此外,还提高了复合材料的热稳定性。
In the context of sustainable development, it is essential to develop high-performance materials from renewable resources. A bio-based epoxy resin precursor was synthesized with eugenol monomer,1,1,3,3-tetramethyldisiloxane and epichlorohydrin as the main materials, and its structure was characterized by 1H-NMR. A KH560 modified hexagonal boron nitride was prepared as a reactive nano-filler for bio-based epoxy composite materials. Compared with pure bio-based epoxy resin, the friction coefficient of composites with 2%BN-KH560 was reduced from 0.711 to 0.498, and the tensile strength increased from 25.92 MPa to 29.82 MPa. In addition, the thermal stability of the composite material was improved. The results of this work show that the introduction of BN-KH560 enhances the mechanical properties, thermal properties and friction properties of bio-based epoxy resin.
