Presently synthesis of edible oil for resin formation and using scrap paper as reinforcement for composite fabrication is still not carried out. In this work, acrylate epoxidized mustard oil (AEMO) was used after blending with a crosslinker N-Vinyl-2-Pyrrolidone (NVP) to fabricate scrap paper reinforced green composites. Mustard oil (MO), Epoxidized mustard oil (EMO) and acrylate epoxidized mustard oil (AEMO) were characterized using iodine value, oxirane content, acid value, FTIR, NMR and viscosity properties. The composites were fabricated using 50:50 ratio of AEMO: NVP and paper loading of 15%, 30% and 60% along with the neat sample. With an increase in paper loading, there was a significant improvement in mechanical properties giving 158.9, 150, 233, 566.66 and 140% improvement in tensile, young’s, flexural strength, flexural moduli and impact strength at 60% loading. The elongation at break showed a value of 20% due to the stiff nature of composite. Biodegradability testing proved an increase in weight loss of composite with time, recording the highest weight loss of 7% for 60% composite sample. Dimensional stability showed excellent result for the neat and lower loaded composite samples. Thermogravimetric and differential scanning colorimetry analysis indicated improvement in thermal stability with higher loading %. Morphological analysis confirmed excellent interfacial adhesion and bonding with higher paper loading %. Dynamic mechanical analysis demonstrated a significant rise in storage modulus (E') and loss modulus (E'') and decline in tan δ with broadening of the peak for maximum loading. Chemical resistance was poor for the highest loaded samples with respect to acids and bases.

使用 N-乙烯基-2-吡咯烷酮作为交联剂的芥子油热固性材料用于废纸复合材料

目前还没有合成食用油用于树脂成型和使用废纸作为复合材料制造的增强材料。在这项工作中,丙烯酸酯环氧化芥子油(AEMO)与交联剂 N-乙烯基-2-吡咯烷酮(NVP)混合后用于制造废纸增强绿色复合材料。芥子油 (MO)、环氧化芥子油 (EMO) 和丙烯酸酯环氧化芥子油 (AEMO) 使用碘值、环氧乙烷含量、酸值、FTIR、NMR 和粘度特性进行表征。复合材料是使用 50:50 的 AEMO: NVP 和 15%、30% 和 60% 的纸张负载以及纯样品制造的。随着纸张装载量的增加,机械性能显着提高,拉伸、杨氏、弯曲强度分别提高 158.9、150、233、566.66 和 140%,60% 载荷下的弯曲模量和冲击强度。由于复合材料的刚性特性,断裂伸长率为 20%。生物降解性测试证明复合材料的重量损失随着时间的推移而增加,60% 的复合材料样品的重量损失最高,为 7%。对于纯的和负载较低的复合样品,尺寸稳定性显示出优异的结果。热重分析和差示扫描比色分析表明,负载百分比越高,热稳定性越好。形态分析证实了出色的界面粘附力和较高的纸张负载百分比。动态力学分析表明储能模量 (E') 和损耗模量 (E'') 显着上升,tan δ 下降,最大负载峰值变宽。
