摘要

通常，发动机支架由橡胶和低碳钢制成，并用Chemlok®粘合剂系统粘合。它可以被改性，以提供天然橡胶和铝之间充分的粘合。因此，本研究旨在通过超声浴和热板两步超声辅助搅拌工艺，对现有Chemlok®胶黏剂体系进行改性，以不同重量百分比的石墨烯纳米片(GNPs)加载。将天然橡胶(NR)-铝(Al)基板在热压机上，在100 kgf/cm2的压力下，在140℃的温度下粘合20分钟。基于ASTM D429标准，采用UTM机器对样品进行90度剥离试验，并对剥离断裂表面进行物理和扫描电镜评价。在改良的Chemlok®205/220体系中，黏附强度随着GNPs的增加而增加。GNPs改良的Chemlok®系统比现有粘合剂提高了30%。分析结果表明，改进是成功的。GNPs分散在一定插层水平的改性体系具有活性官能团、补强效应和热稳定性。

Graphene Nanoplatelets Modified Chemlok® Adhesive System for Natural Rubber – Aluminium Bonded Component in Engine Mount

Generally, the engine mount is made from rubber and mild steel bonded with a Chemlok® adhesive system. It could be modified to provide sufficient bonding between natural rubber and aluminum. Therefore, this work aims to study a nano-manipulated adhesive system by modifying the existing Chemlok® adhesive system at different weight percentages of graphene nanoplatelets (GNPs) loading via two steps ultrasonic-assisted stirring process by ultrasonic bath and hot plate. The natural rubber (NR)-aluminum (Al) substrates were bonded using a hot press machine under the pressure of 100 kgf/cm2 for 20 minutes at 140 °C temperature. The samples were subjected to a 90-degree peel test based on ASTM D429 by the UTM machine, and the peel-fractured surfaces were evaluated both physically and under SEM. The adhesive strength increased with the increment of GNPs in the modified Chemlok® 205/220 system. The GNPs modified Chemlok® system achieved 30% improvement than the existing adhesive. The analyses proved the modification was successful. The modified system with GNPs dispersed at certain intercalation levels showed active functional groups, reinforcing effects, and thermal stability.
