Description

Technical Field

[0001] This utility model belongs to the field of structural adhesive durability testing, and specifically relates to a structural adhesive durability testing device. Background Technology

[0002] Currently, structural adhesives refer to adhesives with high strength (compressive strength > 65 MPa, steel-to-steel tensile bond strength > 30 MPa, shear strength > 18 MPa), capable of withstanding large loads, and resistant to aging, fatigue, and corrosion. They also exhibit stable performance within their expected lifespan and are suitable for bonding structural components that bear strong forces. To ensure that structural adhesives have good performance after bonding, appropriate testing devices are needed to test them.

[0003] However, most existing testing devices use pull-out testing machines to stretch the bonded structural adhesive, but this testing method cannot detect oblique tensile force, making the testing method relatively simple and unable to fully test the performance of the structural adhesive.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a structural adhesive durability testing device to solve the problem that existing testing devices mostly use pull-out testing machines to stretch the bonded structural adhesive. However, this testing method cannot detect oblique tensile force, making the testing method relatively simple and unable to fully test the performance of the structural adhesive.
