The invention provides an aircraft tire bead protective rubber and a preparation method thereof, and belongs to the technical field of high polymer materials. Through reasonable formula preparation, the seam allowance protective glue has the performance characteristics of high tensile strength and tear strength, high hardness, good thermal stability, good cutting resistance and good wear resistance, and also has the advantage of static electricity conduction; the seam allowance protective rubber is good in cutting resistance and high in tensile strength and tearing strength for ultra-high-speed and ultra-high-load aircraft tires, and cracks caused by cutting and tearing of the seam allowance protective rubber can be avoided. The seam allowance protection rubber is good in heat aging resistance and heat stability, the seam allowance protection rubber can be prevented from being disengaged from adjacent parts, and the tire is safe to use.
本发明提供了一种飞机轮胎子口护胶及其制备方法,属于高分子材料技术领域。本发明通过合理的配方配备,使子口护胶具有拉伸强度和撕裂强度高、硬度高、热稳定性好、耐切割和耐磨性能好的性能特点,同时有能导静电的优点;对于超高速、超高载飞机轮胎,子口护胶的耐切割性能好、拉伸强度和撕裂强度高,可以避免子口护胶被切割、撕裂而引起裂纹。子口护胶的耐热老化性能和热稳定性好,可以避免子口护胶与相邻部件间出现脱空,轮胎使用安全。
