“…With excellent mechanical properties and superior environmental stability, building structural adhesives have gained popularity in the engineering field, and realized wide application in the bonding and reinforcement of structural components of buildings and in the reconstruction of existing buildings [1][2][3]. When applied to load-bearing structural components of buildings, structural adhesives are exposed to a complex environment for a long period, and disturbed by various external factors, such as temperature, humidity, and ultraviolet light.…”

This study mainly evaluates the thermal aging properties of a new room temperature cured structural adhesive. Multiple adhesive specimens were thermal aged at 80℃, 100℃, 120℃ and 140℃, respectively, and subjected to the dynamic mechanical analysis (DMA) at different temperatures and frequencies. According to the results of DMA and thermodynamic analysis, the performance of the adhesive changes little after aging at 80℃, 100℃ and 120℃ for 30 days. However, the adhesive performance became unstable at 140℃, and deteriorated rapidly with the extension of aging time. Hence, this structural adhesive is suitable for the environment below 120℃. In addition, the generalized curve of the structural adhesive aging for 20 days at 100℃ was obtained, following the principles of time-temperature equivalence superposition and time-aging time equivalence superposition. The test time was shortened significantly. This research provides an accelerated characterization strategy for the long-term mechanical properties of other polymers, making it possible to obtain the generalized curve of polymers aging for a specific time at a specific temperature.

“…Regarding the environmental effects, ageing is another complication with adhesives. Many studies in different branches, including civil engineering, investigate the durability of adhesives (Unuk et al, 2019;Fevery et al, 2021;Nicklisch and Weller, 2016;Aßmus et al, 2018;Machalická et al, 2019). There is no standard or regulation in civil engineering specifying an exact method of artificial ageing that represents the real years of exposure of the adhesive to the external environment.…”

Glass load-bearing structures, which have been popular in recent years, require careful attention to detail, because with improper design there is a concentration of stress leading to failure and subsequent collapse of the structure. Mechanical connections are mainly used but there are disadvantages such as stress peaks, weakening of the cross-section, or aesthetic reasons. Adhesive connections eliminate these disadvantages. The lack of information and standards about adhesives (except for silicones) obstruct their wide-ranging use. Especially problematic is an ageing of adhesive and its influence on the mechanical properties. This study is focused on experimental testing of two transparent epoxy adhesives that were used for small-scale specimens with float glass. Two sets of specimens were prepared for each adhesive. The first set was an unaged reference set, the second set was exposed to an artificial ageing method based on EN ISO 9142. The specimens were subjected to shear stress in a displacement controlled test. One adhesive showed good mechanical properties in the reference set, but resistance to artificial ageing was poor. The second adhesive does not achieve good mechanical properties in the reference set in comparison to the first adhesive. The artificial ageing method was devastating for the second adhesive. Poor mechanical properties of the second adhesive could be caused by the age of the uncured adhesive. The first adhesive can only be recommended for the interior where the adhesive is not exposed to aggressive environmental effects.
