Technical Field

[0001] The utility model belongs to the technical field of engineering quality inspection equipment, in particular to a tool for making specimens for detecting the bonding strength of adhesives. Background Technique

[0002] Adhesives are widely used in the construction industry, such as: tile and stone pasting, floor installation, thermal insulation material bonding, etc. In order to ensure that the bonding performance, durability and adaptability of adhesives meet the requirements of construction projects, it is necessary to make specimens for detecting the bonding strength of adhesives, and then use a tensile testing instrument to test the specimens to evaluate the bonding performance of adhesives.

[0003] At present, the manufacturing method of specimens for detecting the bonding strength of adhesives can be adjusted according to specific detection standards and adhesive types. The following are the general manufacturing steps: (1) Prepare materials: According to the detection requirements, prepare adhesives and square substrates, and inlay the square substrates in a metal frame; (2) Surface treatment: Clean the surface of the substrates to remove oil stains, dust and other contaminants. For some substrates, it may be necessary to perform grinding or surface treatment to improve the bonding strength; (3) Glue application: According to the usage instructions of the adhesive, evenly apply the adhesive on the surface of the square substrate, control the thickness and uniformity of the glue application to ensure full contact between the adhesive and the substrate; (4) Cut and apply glue: Use a tool to draw horizontal and vertical lines on the glue application layer with a knife to form several square-shaped glue layer specimens arranged in a matrix, remove the glue application layer around the square-shaped glue layer specimens, and form several non-adhesive square-shaped glue layer specimens arranged in a matrix on the square substrate; (5) Bond the traction blocks: According to the usage instructions of the adhesive, after the adhesive is cured and dried, use a strong glue to bond traction blocks of the same shape and size on each glue layer specimen; when the adhesives and the strong glue reach the bonding strength time, the production of specimens for detecting the bonding strength of adhesives is completed and can be used for bonding strength detection.
