中文摘要:
      对飞机结构用新型胶体密封剂的高低温稳定性、分油性及耐介质性测试与表征方法进行了研究,建立了新型胶体密封剂的主要性能指标体系。采用“蒸馏水浸泡+剥蚀溶液浸渍” 组成的加速腐蚀试验方法,对新型胶体密封剂的腐蚀防护性进行了深入研究。结果表明,新型胶体密封剂具有高低温稳定性好、不挥发物含量高、分油量小、耐介质性强的性能特点,在-60~180 ℃的温度范围内始终保持胶体状态物,满足低温不凝固和高温不流淌的应用要求,并兼具密封防水和防腐双重功效,适用于解决现役飞机结构密封防水问题。
英文摘要:
      Measurement and characterization technologies of high and low temperature stability, oil separation, and medium resistance of new colloidal sealant for aircraft structures were investigated, and the main technical index system was established. The corrosion protection performance of new colloidal sealant was thoroughly assessed and validated using "distilled water + EXCO dipping" laboratory accelerated simulation environmental test method. The experimental results showed that this kind of new colloid seal waterproof technique has the characteristics of good thermal stability, high involatile content, low oil separation, strong medium resistance, always maintain colloidal substance at temperature from -60 to 180℃, which meets the application demands of un-solidification under low temperature and no fluidity under high temperature, and has dual functions of seal waterproof and anticorrosion, which are especially suitable for solving the seal waterproof problems of aircraft structures.
