一、前言航空橡胶目前使用量较大的是丁腈、丁苯、和天然橡胶等。这些橡胶分子链中具有不饱和双键,这些不饱和活性基团的存在是橡胶老化的内在因素,而大气中氧、臭氧、温度、光、微生物等是橡胶老化的主要外在因素。氧、臭氧等活性物质使橡胶链的不饱和键打开,产生断裂、交联,出现表面龟裂、泛白等现象.物理机械性能下降,以致失去使用功能。因橡胶制品在加工、装配、贮存、使用过程中易受环境 First, the foreword Aeronautical rubber is currently used in larger nitrile, butadiene, and natural rubber. These rubber molecules have unsaturated double bonds in the molecular chain. The existence of these unsaturated groups is an inherent factor in rubber aging. However, atmospheric oxygen, ozone, temperature, light and microorganisms are the main external factors of rubber aging. Oxygen, ozone and other active substances to open the unsaturated bond of the rubber chain, resulting in broken, cross-linked, there surface cracking, whitening and other phenomena.Mechanical and mechanical properties decline, resulting in loss of function. Due to rubber products in the processing, assembly, storage, use of the process vulnerable to the environment
