摘要
使用废弃聚苯乙烯作为制备生物废料衍生炭的添加剂可提供显著的新特性,从而提高钢表面环氧涂层的性能。这项研究利用桉树木屑和聚苯乙烯的共热解过程制备了一种经济有效的准石墨化碳(QGC),并将其混合在环氧树脂(EP)基质中,以增强涂层性能。傅立叶变换红外光谱(FTIR)、X 射线衍射(XRD)、拉曼光谱(Raman)、扫描电子显微镜(SEM-EDX)、热重分析(TGA)等对 QGC 材料进行了表征。结果表明,与纯 EP 涂层相比,在 EP 基体中加入 0.1 wt.% 的 QGC 可提高 98.6 % 的耐腐蚀性,并增强机械性能,硬度提高了 245.45 %,弹性模量提高了 57.31 %。显微分析表明,与纯 EP 涂层相比,该涂层表面更光滑、更紧凑,结构缺陷更少。附着力测试结果为 4B、5B 级,水接触角提高到 102.8°,而纯 EP 涂料的水接触角为 61.6°。这些通过环保工艺生产的环保材料可以安全地替代用于防腐蚀的传统有毒化学品,尤其是在海洋环境中。
Co-pyrolysis of waste wood and plastic to produce quasi graphitic carbon: enhanced biochar properties for metal coatings through safe sequestration and green technology
Use of waste polystyrene as an additive in the preparation of biowaste derived char can provide significant new properties that enhance the performance of the epoxy coating on steel surface. This work establishes a cost-effective Quasi-graphitic carbon (QGC) derived from the co-pyrolysis of Eucalyptus wood chips and polystyrene as a mix in epoxy (EP) matrix for enhanced the coating properties. The QGC material was characterized by FTIR, XRD, Raman, SEM-EDX, TGA, etc. Results show the incorporation of 0.1 wt.% QGC to the EP matrix enhances corrosion resistance by 98.6 % and boosts mechanical properties with a 245.45 % increase in hardness and a 57.31 % rise in elastic modulus compared to pure EP coatings. Microscopic analysis reveals a smoother, more compact surface with fewer structural defects comapred to pure EP coating. Adhesion tests score the category of 4B, 5B, and water contact angle improve to 102.8°, compared to 61.6° for pure EP coatings. These eco-friendly materials, created through environmentally conscious processes can be a safe alternative to the conventional toxic chemicals used to protect against corrosion,particularly in marine environments.
