[0003] The existing silicone structural adhesive needs to be tested for its tear resistance before use. Most of the existing tear resistance equipment uses two hydraulic cylinders to pull two test pieces bonded by silicone structural adhesive. The force applied by the cylinder and the detachment between the two specimens are used to calculate the tear resistance of the silicone structural adhesive; however, the existing two specimens have a long curing time for the silicone structural adhesive in contact, and it is necessary to wait for a long time. time, resulting in low efficiency in testing the tear resistance of silicone structural adhesives

The invention discloses silicone structural adhesive tear resistance test equipment and a test method, and relates to the technical field of structural adhesive tear resistance test, including a base, a clamping mechanism arranged on the top of the base for clamping two test pieces, located The glue gun directly above the specimen and the driving mechanism used to drive the glue gun to apply glue. The top of the driving mechanism is connected to the bracket on the top of the base through an electric telescopic rod. The inner wall on the left side of the bracket is inclined to install a spray for accelerating the solidification of the structural glue. mechanism, the right side of the bracket is provided with a trigger mechanism that is the same as that for opening the spray mechanism, and the trigger mechanism is electrically connected to the control panel on the outer surface of the bracket. In the present invention, the two test pieces are clamped by the clamping mechanism, and the structural glue is filled between the two test pieces through the glue gun and the driving mechanism, and the trigger mechanism is driven to start the spraying process during the movement of the driving mechanism. The mechanism sprays hot water mist on the structural adhesive to accelerate the solidification of the structural adhesive, thereby improving the efficiency of testing the tear resistance of the silicone structural adhesive.
Description
technical field [0001] The invention relates to the technical field of testing the tear resistance of structural adhesives, in particular to equipment and methods for testing the tear resistance of silicone structural adhesives. Background technique [0002] High-performance silicone structural adhesive is a neutral curing structural adhesive designed for structural bonding assembly in building curtain walls. It can be easily extruded and used under wide temperature conditions, and it can be cured into excellent, durable high modulus and high elastic silicone rubber by relying on the moisture in the air. [0003] The existing silicone structural adhesive needs to be tested for its tear resistance before use. Most of the existing tear resistance equipment uses two hydraulic cylinders to pull two test pieces bonded by silicone structural adhesive. The force applied by the cylinder and the detachment between the two specimens are used to calculate the tear resistance of the si...
