The effect of nanosilicates on the performance of natural rubber latex (NRL)-based adhesives was studied. For comparison, a reference filler (Kaolin clay) was included in the study. Natural leather was used as the adherend and the adhesive strength was recorded by measuring the peel strength. The results indicated that incorporation of nanosilicates imparted increased peel strength to NRL-based adhesives. Transmission electron microscopy (TEM) studies confirm the excellent dispersion of silicate platelets in the NR matrix. Peel strength showed maximum value for NRL-based adhesive containing 2phr nanosilicate. The results of thermogravimetric analysis (TGA) showed that addition of nanosilicates imparted better thermal stability into the adhesives. Conventional clay could not make any improvement in properties of the adhesives. Viscosity of NRL-based adhesive was increased by the addition of the nanosilicates which confirms the better dispersion of the nanofiller into the NR matrix. Fourier transform infrared (FTIR) spectroscopic analysis and contact angle measurements of the NRL/nanosilicate adhesives were also carried out.

研究了纳米硅酸盐对天然橡胶胶乳（NRL）基胶粘剂性能的影响。为了进行比较，研究中包括了参考填料（高岭土）。使用天然皮革作为被粘物，并通过测量剥离强度来记录粘合强度。结果表明，纳米硅酸盐的掺入赋予基于NRL的粘合剂增加的剥离强度。透射电子显微镜（TEM）研究证实了硅酸盐血小板在NR基质中的优异分散性。对于包含2phr纳米硅酸盐的NRL基粘合剂，剥离强度显示出最大值。热重分析（TGA）的结果表明，添加纳米硅酸盐赋予粘合剂更好的热稳定性。常规粘土不能改善粘合剂的性能。通过添加纳米硅酸盐，可以增加基于NRL的粘合剂的粘度，这证实了纳米填料更好地分散在NR基质中。还进行了NRL /纳米硅酸盐胶粘剂的傅立叶变换红外（FTIR）光谱分析和接触角测量。
