[0002] In the research, development, verification, and testing of auxiliary building materials, adhesive strength is a crucial performance parameter and an important indicator for evaluating the performance of materials such as building putty and waterproof coatings. Adhesive strength refers to the adhesive force borne per unit bonding surface, and it consists of the cohesive strength of the adhesive layer and the bonding strength between the adhesive layer and the substrate surface.

Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or constructions will be omitted where they may cause confusion in understanding this utility model.

[0051] Figure 1 A perspective view of a coating adhesion strength testing device according to an embodiment of the present invention is shown schematically.

[0052] An embodiment of this utility model provides a coating adhesion strength testing device, such as... Figure 1 As shown, the system includes: a test platform 1, at least two adhesive components 2, and a tension component 4. Multiple adhesive components 2 are suitable for applying different coatings. Each adhesive component 2 includes a first adhesive element 21 and a second adhesive element 22 disposed opposite to each other. The first adhesive element 21 is fixed to the test platform 1, and the second adhesive element 22 is bonded to the first adhesive element 21 by the coating. The tension component 4 is installed on the test platform 1 and is used to drive multiple second adhesive elements 22 to move in a first direction, causing the multiple second adhesive elements 22 to separate from their respective bonded first adhesive elements 21. Different coating adhesion forces are obtained according to the separation order of the first adhesive elements 21 and the second adhesive elements 22. The first direction is perpendicular to the bonding surfaces of the first adhesive elements 21 and the second adhesive elements 22.

[0053] According to the above setup, by setting multiple bonding components 2, viscosity tests of different coatings can be performed simultaneously on the same test platform 1, realizing synchronous testing of the bonding strength of different coatings, ensuring the uniformity of the test environment. The relative setting of the first bonding component 21 and the second bonding component 22, as well as the uniform application of force by the tension component 4 in the first direction perpendicular to the bonding surface, reduce errors in the test process and improve the reliability of the test results.

[0054] Furthermore, under the action of the tension component 4, as the multiple second adhesive components 22 gradually separate from their respective first adhesive components 21, the weaker the adhesive force of the coating, the earlier the corresponding adhesive components 2 separate. Therefore, by recording the tension applied by the tension component 4 at each separation and combining it with the number of adhesive components 2 that remain bonded, the average adhesive force of the currently separated coating can be calculated. In this way, the specific adhesive force of the coating between the first adhesive component 21 and the second adhesive component 22 can be accurately determined each time separation occurs.

[0055] In one illustrative embodiment, such as Figure 1 As shown, the end of the first adhesive 21 is provided with a receiving cavity that matches the second adhesive 22 to receive the second adhesive 22. The coating is uniformly applied to the bottom of the receiving cavity beforehand, and the second adhesive 22 is then bonded.

[0056] Based on the above setup, the bonding surface size of each bonding component 2 is the same, ensuring the uniformity of the test environment and facilitating subsequent calculation of bonding strength.

[0057] Figure 2 An exploded view schematically illustrates the connection relationship of the mounting plates according to an embodiment of the present invention.

[0058] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the tension assembly 4 includes a support frame 41 mounted on the test platform 1 and a mounting plate 42 movably mounted on the support frame 41. The mounting plate 42 is configured to move in a first direction and connect to the second adhesive pieces 22 of the plurality of adhesive assemblies 2. It also includes a drive unit 43 adapted to drive the mounting plate 42 and the plurality of second adhesive pieces 22 to move in the first direction, the drive unit 43 being mounted on the support frame 41. When the drive unit 43 drives the plurality of second adhesive pieces 22 closer to their respective first adhesive pieces 21, different coatings are used to bond the first adhesive pieces 21 and the second adhesive pieces 22. Then, the drive unit 43 drives the second adhesive pieces 22 away from the first adhesive pieces 21, causing the second adhesive pieces 22 to separate from their respective first adhesive pieces 21, thereby obtaining different adhesive forces of the coatings.

[0059] According to the above configuration, the drive unit 43 precisely controls the approach and separation of the second adhesive component 22 and the first adhesive component 21, thereby achieving standardized testing during the coating bonding process. The precise control of the drive unit 43 ensures that the bonding strength of various coatings can be compared and evaluated under uniform testing conditions. This not only improves the repeatability and reliability of the test but also simplifies the operation process, making the acquisition of coating adhesion more convenient and accurate.

[0060] In one illustrative embodiment, such as Figure 1 and Figure 2As shown, the tension assembly 4 also includes a tension sensor 44 connected between the drive unit 43 and the mounting plate 42, which is suitable for obtaining the adhesive force when the first adhesive part 21 and the second adhesive part 22 are separated.

[0061] Based on the above setup, the integrated tensile sensor 44 can accurately measure and record the adhesion of the coating, providing direct data support for the quantitative analysis of the adhesion performance of different coatings. This not only improves the accuracy of the test results but also makes the assessment of coating adhesion more objective and scientific, thereby helping to optimize coating formulations and improve production processes.

[0062] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the drive unit 43 includes a second linear driver 431 and a connector 432. The second linear driver 431 is mounted on the support frame 41; the connector 432 is mounted on the output end of the second linear driver 431; wherein, the tension sensor 44 is mounted inside the connector 432 and connected to the mounting plate 42.

[0063] According to the above configuration, by integrating the tensile sensor 44 into the connector 432 of the drive unit 43, the force applied during the coating adhesion strength test can be directly and accurately measured and recorded.

[0064] According to an embodiment of the present invention, the connector 432 is configured as a box shape to better install the tension sensor 44, wherein the tension sensor 44 is installed between the connector 432 and the mounting plate 42 by a threaded connection, and / or a high-strength structural adhesive is applied between the tension sensor 44 and the connector 432 and the mounting plate 42 to ensure that the connection strength of the tension sensor 44 is much greater than the tensile force required for the test coating.

[0065] In one illustrative embodiment, such as Figure 1 As shown, the tension assembly 4 also includes at least two guide units 45, spaced apart between the support frame 41 and the mounting plate 42, suitable for assisting the mounting plate 42 in moving in the first direction. By setting the guide units 45, the straightness and stability of the mounting plate 42 during movement are ensured, lateral swaying and offset are reduced, thereby improving the accuracy and repeatability of the coating adhesion strength test.

[0066] In one illustrative embodiment, such as Figure 1 As shown, each guide unit 45 includes: a sleeve 451 mounted on a support frame 41 and configured to extend in a first direction; and a columnar rod 452 movably mounted within the sleeve 451 in the first direction and connected to a mounting plate 42, adapted to guide the mounting plate 42 to move in the first direction.

[0067] In one illustrative alternative embodiment, each guide unit 45 includes a guide rail extending in a first direction and a slider slidably disposed within the guide rail, the guide rail being mounted on a support frame 41 and / or a test platform 1, and the slider being fixedly connected to a mounting plate 42 to guide the mounting plate 42 to move along the guide rail in the first direction.

[0068] Figure 3 A schematic diagram of the fixing component according to an embodiment of the present invention is shown.

[0069] In one illustrative embodiment, such as Figure 3 As shown, it also includes a fixing component 3, which is installed on the test platform 1 and is suitable for fixing multiple first adhesive parts 21 to prevent the multiple first adhesive parts 21 from moving with their respective second adhesive parts 22.

[0070] In one illustrative embodiment, the fixing component 3 includes a mounting frame 31 mounted on the test platform 1 and adapted to place first adhesive pieces 21 of a plurality of adhesive components 2, and a plurality of fixing units 33 mounted on the mounting frame 31 and adapted to limit the plurality of first adhesive pieces 21 respectively.

[0071] In one illustrative embodiment, the mounting bracket 31 is configured to be fitted over the outside of a plurality of first adhesive members 21 to directly limit the plurality of first adhesive members 21 in a first direction.

[0072] In one illustrative embodiment, the fixing unit 33 includes, but is not limited to, a clamp, including a pair of relatively movable clamping members for fixing the first adhesive member 21 from both sides to prevent the first adhesive member 21 from moving.

[0073] In an alternative embodiment, a plurality of first adhesive members 21 are detachably mounted to the mounting bracket 31 by bolts and nuts.

[0074] In one illustrative embodiment, a plurality of first adhesive pieces 21 are arranged side by side on a mounting bracket in the same direction. Two fixing units 33 are provided, located at the two ends of the arrangement direction of the plurality of first adhesive pieces 21, respectively. They are suitable for clamping the plurality of first adhesive pieces 21 arranged together. The friction between the fixing unit 33 and the first adhesive piece 21 and the two adjacent first adhesive pieces 21 is used to prevent the first adhesive piece 21 from moving in the first direction.

[0075] In detail, the mounting bracket 32 ​​is constructed in the shape of a box, with a width equal to the width of the first adhesive piece 21, which can restrict the movement of the multiple first adhesive pieces 21 placed therein in the width direction of the mounting bracket 32, and two fixing units 33 are arranged at both ends of the mounting bracket 32 ​​in the length direction to clamp the multiple first adhesive pieces 21.

[0076] According to embodiments of the present invention, such as Figure 3As shown, the adhesive component 2 is configured as two; the fixing component 3 also includes a spacer block 32, which is installed on the mounting bracket 31 and is suitable for spacing the two first adhesive parts 21; the two fixing units 33 are respectively located at the opposite ends of the two first adhesive parts 21 and are suitable for cooperating with the spacer block 32 to clamp the two first adhesive parts 21.

[0077] In one illustrative embodiment, such as Figure 3 As shown, each fixing unit 33 includes: a first linear driver 331, mounted on the mounting bracket 31; and a limiting plate 332, mounted on the output end of the first linear driver 331; wherein the first linear driver 331 is adapted to drive the limiting plates 332 to move closer to each other or closer to the spacer 32 located in the middle, so as to clamp and fix a plurality of first adhesive pieces 21.

[0078] In one illustrative embodiment, a control center 5 is also included, mounted on the test platform 1, comprising: a processing unit adapted to obtain the adhesive strength of the coating based on the dimensions and adhesive force of the bonding surfaces of the first adhesive 21 and the second adhesive 22; and a display screen 51 adapted to display the adhesive force and / or adhesive strength.

[0079] In detail, when two bonding components 2 are set, since the tension sensor 44 only feeds back the applied tension value, during the initial tension increase process, the processing unit calculates the bonding strength by using the dimensions of the bonding surfaces of the two bonding components 2 to obtain the tension value. When the tension sensor 44 detects a sudden decrease in the tension value, it proves that one of the bonding components 2 has been damaged. At this time, the processing unit automatically switches to calculating the bonding strength by using the dimensions of the bonding surfaces of one bonding component 2. Finally, the processing unit will feed back two data points, which not only allows for a comparison of the bonding strength of the two coatings, but also provides accurate test data for subsequent analysis.

However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination.
