Abstract

Using waste materials in polymer composites has gained attention for its ecological benefits and material properties. This work investigates the production of composites using waste glass powder and Ortho-phthalic polyester resin. Before cure processing, the glass powder was added to the polymer matrix at a 50 wt% ratio. Characterization techniques included scanning electron microscopy (SEM), contact angle measurement, thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FTIR), and tensile tests. Flammability tests revealed that the compounds exhibit flame-retardant behavior. The composites exhibited improved mechanical properties compared to pure resins, with increased compressive strength (3–15 %), impact strength (9–16 %), and a higher tensile modulus (2.5 times). The results show that glass can reinforce polymers while maintaining hydrophobic properties. The composite conductivity with glass waste was reduced by almost 95 % compared to pure resin. These findings suggest that glass-reinforced polymers can be effectively used in electrical applications as insulators, protective mechanisms, or carriers in electrical circuits.

电气工业用玻璃废料邻苯二甲酸聚酯基复合材料的研制

废旧材料在高分子复合材料中的应用因其生态效益和材料性能而备受关注。本文研究了利用废玻璃粉和邻苯二甲酸聚酯树脂制备复合材料。在固化处理之前，玻璃粉以50%的wt%的比例添加到聚合物基体中。表征技术包括扫描电子显微镜（SEM）、接触角测量、热重分析（TG）、傅里叶变换红外光谱（FTIR）和拉伸测试。可燃性试验表明，该化合物具有阻燃性。与纯树脂相比，复合材料的力学性能得到了改善，抗压强度提高了3 - 15%，冲击强度提高了9 - 16%，拉伸模量提高了2.5倍。结果表明，玻璃可以在保持聚合物疏水性的同时增强聚合物。与纯树脂相比，玻璃废料复合材料的电导率降低了近95%。这些发现表明，玻璃增强聚合物可以有效地应用于电气应用中，作为绝缘体、保护机制或电路中的载体。
