It is a well-known fact that extreme environmental conditions are the cause of a large number of adhesive failure. To be able to minimize such problem, an experimental study on graphene nanoplatelets (GNP) effects into an industrial mono component adhesive was proposed. The nano-modified adhesive was used into single lap joints of galvanized steel commonly employed in automotive industry. Due to SKP-456LB's large viscosity and the GNP large concentration (up to 3 wt%), an alternative method for nanostructure dispersion was employed. A grease worker, an equipment commonly employed for lubricant consistency and shear stability testing, was employed as a homogenization device. To be able to understand how the GNP nanostructures affected SKP-456LB's overall mechanical response to severe environmental conditions, four sets of single lap joints (SLJ) were prepared and tested after environmental exposure. The environmental conditions can be summarized as, i.e. base line (no exposure to extreme environment), 500 h at 100C, 500 h at 95% relative humidity and temperature of 40C, and 500 h under salt spray. The GNP addition to pure SKP-456LB increased the apparent shear strength by approximately 29%. GNP in small concentrations (1.0 wt%) \ did not provide an improvement on SKP-456LB adhesive mechanical properties. This phenomenon could be due to agglomeration/cluster formation. The remaining load bearing for the 3 wt % concentration (around 75% of the baseline data), after exposition to harsh environment, was still larger than the ones with GNP smaller concentration; The addition of carbon based nanostructures led to a mix failure mode where cohesive and adhesive modes were acting at the same time.

众所周知，极端环境条件是导致大量粘合剂失效的原因。为了能够最大限度地减少此类问题，提出了石墨烯纳米片（GNP）对工业单组分粘合剂的影响的实验研究。纳米改性粘合剂用于汽车行业常用的镀锌钢的单搭接接头。由于 SKP-456LB 的粘度大且 GNP 浓度大（高达 3 wt%），因此采用了另一种纳米结构分散方法。润滑脂工人，一种常用于润滑剂稠度和剪切稳定性测试的设备，被用作均质设备。为了能够了解 GNP 纳米结构如何影响 SKP-456LB 对恶劣环境条件的整体机械响应，在环境暴露后准备并测试了四组单搭接接头（SLJ）。环境条件可概括为，即基线（未暴露于极端环境），100℃下500小时，95%相对湿度和40℃温度下500小时，以及盐雾下500小时。添加到纯 SKP-456LB 中的 GNP 使表观剪切强度增加了大约 29%。小浓度 (1.0 wt%) 的 GNP 没有改善 SKP-456LB 粘合剂的机械性能。这种现象可能是由于团聚/簇的形成。3wt%浓度（基线数据的75%左右）的剩余承载力，暴露于恶劣环境后，仍大于GNP浓度较小的；
