| 目的 通过测试不同胶粘剂在不同温度及不同环境介质中的粘结强度，研究胶粘剂的环境适应性，为直升机复合材料胶接维修提供工艺参考和数据支撑。方法 选取HYSOL EA9396(美国汉高)和HUITIAN HT6119(中国回天)2种胶粘剂，测试其黏度、适用期、挥发性、玻璃化转变温度、拉伸强度、弯曲强度和压缩强度等基本性能，并使用金属–金属胶接方式，在不同温度下和不同环境介质(普通大气、水、航空液压油、RP-3煤油、盐雾和湿热)中，测试其拉伸剪切性能。结果 随温度升高，2种胶粘剂的拉伸剪切性能均发生下降。在121 ℃前，HT6119胶粘剂的拉伸剪切性能优于EA9396胶粘剂；121 ℃(含)至149 ℃间EA9396胶粘剂拉伸剪切性能优于HT6119胶粘剂；当温度上升至177 ℃时，两者的性能相当。2种胶粘剂在不同环境介质均有较好的胶接性能，HT6119胶粘剂除了在航空液压油和盐雾条件下的拉伸剪切性能略低于EA9396胶粘剂外，其他环境条件下都优于EA9396胶粘剂。结论 EA9396和HT6119胶粘剂的拉伸剪切性能均随温度升高而下降，EA9396在中低温下的胶粘性能较好，HT6119在高温条件下胶粘性能较好。2种胶粘剂在典型环境介质中的胶粘性能均无大幅下降(相较普通大气环境)，但2种胶粘剂在不同介质中的拉伸剪切性能有区别。在进行胶粘剂选择时，可根据具体的使用环境进行合理选择。 |

| The work aims to study the environmental adaptability of adhesives by testing the bond strength of different adhesives at different temperature and in different media, to provide process reference and data support for the adhesive maintenance of helicopter composite materials. Two kinds of adhesives were selected:HYSOL EA9396 (Henkel, USA) and HUITIAN HT6119 (Huitian, China). The basic properties of both adhesives such as viscosity, service life, volatility, glass transition temperature, tensile strength, bending strength and compression strength were tested. Then, the tensile shear properties were tested at different temperature and in different media (ordinary atmosphere, water, aviation hydraulic oil, RP-3 kerosene, salt spray and humid heat) by metal-metal bonding. The tensile shear properties of both adhesives decreased with the temperature increasing. When the temperature was lower than 121 ℃, the tensile shear properties of HT6119 adhesives were better than those of EA9396 adhesives. When the temperature was between 121 ℃ (inclusive) and 149 ℃, the tensile shear properties of EA9396 adhesives were better than those of HT6119 adhesives. When the temperature rose to 177 ℃, the properties of both adhesives were similar. Both adhesives had good bonding properties in different media. The tensile shear properties of HT6119 adhesives were slightly lower than those of EA9396 adhesives under the conditions of aviation hydraulic oil and salt spray, but better than those of EA9396 adhesives under other environmental conditions. The tensile shear properties of EA9396 and HT6119 adhesives decrease with the increasing temperature. The adhesive properties of EA9396 are better at medium and low temperature, and the adhesive properties of HT6119 are better at high temperature. The adhesive properties of the two kinds of adhesives do not decrease significantly in typical environmental media (compared with ordinary atmospheric environment), but the tensile shear properties of the two kinds of adhesives in different media are different. Therefore, the adhesives can be selected reasonably according to the specific service environment. |
