根据某飞机座舱透明件边缘连接处的要求,研制了一种座舱透明件边缘连接用改性丙烯酸酯胶黏剂。通过对改性丙烯酸酯胶黏剂适用期和不同固化条件对胶黏剂性能的影响进行研究,确定了胶黏剂的适用期、固化温度、固化时间等工艺参数;同时对胶黏剂对3号有机玻璃的应力-溶剂银纹性能的影响进行了研究,并对胶黏剂的耐介质性能、耐盐雾性能、耐温度冲击性能、低温老化性能、高温老化性能、湿热老化性能和紫外老化性能进行了考核,上述试验的研究和考核表明座舱透明件边缘连接用改性丙烯酸酯胶黏剂的施工工艺和综合性能可以满足某飞机座舱边缘连接处的使用要求。
According to the requirements of the junction of the transparent parts of a cockpit cockpit, a kind of modified acrylate adhesive for the transparent connection of cockpit transparent parts was developed. Through the study on the influence of the modified acrylate adhesive’s application period and different curing conditions on the adhesive properties, the process parameters such as the pot life, the curing temperature and the curing time of the adhesive are determined. At the same time, The effect of the stress-solvent silver streak on the properties of the adhesive was studied. The influences of the medium resistance, salt spray resistance, temperature shock resistance, low temperature aging, high temperature aging, wet heat aging and UV aging Performance of the assessment, the test research and assessment showed that the cockpit edge transparent acrylic adhesive connection construction process and comprehensive performance to meet the aircraft cockpit edge of the junction of the use requirements.
