Background

When the adhesive bonding structure is used, the adhesive bonding structure always needs to have the best mechanical property, and the main index for evaluating the mechanical property of the adhesive bonding structure at present is bonding strength. The bonding strength refers to the stress required for breaking the interface between the adhesive in the adhesive member and the adherend or the vicinity thereof under the action of an external force, and is also called as the bonding strength. The bonding strength is the stress required for breaking the adhesive system, and the magnitude of the stress depends on the adhesive force, the mechanical property of the adhesive, the property of an adherend, the bonding process, the joint form, the stress condition (type, size, direction and frequency), the environmental factors (temperature, humidity, pressure and medium), the test conditions, the experimental technique and the like.

Adhesive structures such as common mortar, tile glue, waterproof paint, thermal insulation material and the like need to be subjected to adhesive strength test before use. In the prior art, the mortar is coated on a substrate with a certain size, and then the tensile bonding strength is measured by a tensile method by using a drawing tester.

However, when the traditional drawing tester is adopted to carry out the bonding strength test in the prior art, the drawing tester usually needs to rotate a plurality of bolts to fasten the test piece, so that the test piece is cumbersome to assemble and disassemble, and the bonding strength test cannot be carried out conveniently. Therefore, how to provide a test device so that a test piece can be conveniently operated in the adhesive strength test is a technical problem to be solved by those skilled in the art.
