Description

Technical Field

[0001] This utility model relates to an adhesion force comparison testing device, and more particularly to an adhesion force comparison testing device for anti-icing coatings. Background Technology

[0002] Anti-icing coatings, commonly known as anti-icing and snow coatings, are suitable for various coating methods. They can self-cur at room temperature, forming a 30μm dry film on the protected surface, which can prevent ice and snow adhesion. They also have composite functions such as corrosion resistance, wear resistance, anti-aging, and surface self-cleaning. They can be used on structures that need to be protected from ice and snow, such as aircraft, ships, power lines, and telecommunication lines. The adhesion of anti-icing coatings is often tested by methods such as cross-cut adhesion test, tensile test, and pull-out adhesion test, which requires the use of comparative testing equipment.

[0003] For example, a comparative testing device for the adhesion of anti-icing coatings, disclosed in Chinese Patent Publication No. CN222652815U, includes: a worktable; an anti-icing coating is applied to a substrate; a lifting assembly is used to lower a plywood plate and attach it to the surface of the substrate; a first motor drives multiple cams to rotate; the rotation of the cams causes the top columns to move upward and impact the bottom surface of the substrate; the impact of the multiple top columns on the substrate causes the substrate to vibrate, thereby expelling air bubbles in the anti-icing coating; after the coating solidifies, the plywood plate is raised, and a tension sensor provides feedback on the tension; the adhesion force is determined by the value fed back by the tension sensor; the above steps are performed on various anti-icing coatings to conduct a comparative test of adhesion force, thus achieving the effect of comparative testing of the adhesion force of anti-icing coatings and facilitating the expulsion of air bubbles in the anti-icing coating;

[0004] Some problems were found when using the existing anti-icing coating adhesion comparison test equipment. The coating is used to bond the substrate and the plywood together and then pull them together to test the adhesion. First of all, the coating normally takes 24 hours or even longer to dry completely. Since there is no space for moisture to evaporate when the two sides are bonded, the bonding time is even longer. A single test requires at least a day for the coating to dry and cure, which leads to a lot of time consumption for the test and low equipment utilization. Utility Model Content

[0005] The purpose of this invention is to provide a comparative testing device for the adhesion of anti-icing coatings, so as to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a comparative testing device for the adhesion force of anti-icing coatings, comprising a base, a stand fixedly connected to the base, an electric telescopic rod fixedly connected to the stand, a support arm fixedly connected to the upper end of the electric telescopic rod, and connecting mechanisms fixedly connected to both the support arm and the base. A coating adhesion component is engaged between the connecting mechanisms, and the two connecting mechanisms are connected by a connecting rope. The coating adhesion component includes a fixing plate and a base plate. A through hole is formed in the fixing plate, and a threaded hole is formed on the bottom of the base plate. A fixing bolt is provided in the through hole, and the fixing bolt is threadedly engaged with the threaded hole.

[0007] Preferably, a limiting groove is provided on the front of the support frame, a limiting slider is slidably installed in the limiting groove, and a U-shaped support fork is fixedly connected to the front of the limiting slider.

[0008] Preferably, a threaded sleeve block is fixedly connected to one side of the U-shaped support fork, and a fastening bolt is installed on the internal thread of the threaded sleeve block.

[0009] Preferably, the connecting mechanism includes two connecting plates, which are symmetrically arranged. Each connecting plate has a locking block fixedly connected to its upper surface. A fixed mounting base is fixedly connected to the lower part of one of the connecting plates, and the fixed mounting base is fixedly connected to the base and the support arm.

[0010] Preferably, a connecting ring is fixedly attached to another connecting plate, and the connecting ring cooperates with the connecting rope.

[0011] Preferably, the fixing plate has limit slots on both sides, and the limit slots cooperate with the locking blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using the interlocking of the locking block and the limiting slot, the coating adhesion component is locked between the two connecting plates. The two substrates can be pre-configured and bonded, and the coating can be fully dried before testing, which does not require a long time for the equipment.

[0014] 2. By using two groups of coated components, one group serves as a control group, which can use commercially available Grade 1 or Grade 1 coatings, and the other group serves as a test group, using the coating to be tested. During the test, observe which group of substrates separates, which can provide a relatively intuitive and quick way to know whether the adhesion of the test coating meets the standard.

[0015] 3. By placing the U-shaped support fork below the upper connecting mechanism, in the event of separation of the upper substrate, the U-shaped support fork can support the falling connecting plate, preventing it from falling directly and damaging the equipment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a comparative testing device for the adhesion force of anti-icing coatings, including a base 1, a stand 101 fixedly connected to the base 1, an electric telescopic rod 2 fixedly connected to the stand 101, a support arm 201 fixedly connected to the upper end of the electric telescopic rod 2, and a connecting mechanism 4 fixedly connected to both the support arm 201 and the base 1. A coating adhesion component 5 is engaged between the connecting mechanisms 4. The two connecting mechanisms 4 are connected by a connecting rope 6. The coating adhesion component 5 includes a fixing plate 501 and a base plate 502. A through hole 504 is opened in the fixing plate 501, and a threaded hole 506 is opened on the bottom of the base plate 502. A fixing bolt 505 is provided in the through hole 504, and the fixing bolt 505 is threadedly engaged with the threaded hole 506.

[0023] In this embodiment, a fixing bolt 505 is screwed into a threaded hole 506 through a through hole 504 to fix the substrate 502 onto the fixing plate 501, forming a test component. The substrate 502 is made of a suitable material, such as a rough-surfaced metal plate. Using the fixing bolt 505 to fix the substrate 502 facilitates later testing of coating adhesion by replacing the substrate 502 with one of different materials. A certain amount of coating is sprayed onto the substrate 502, and then another test component substrate 502 is attached to it. The two test components form a coating adhesion component 5. Two sets of coating adhesion components 5 are provided, one of which serves as a control group. Commercially available Grade 0 or Grade 1 coatings can be used. The two sets of coatings... The coating adhesion components 5 are snapped onto the connecting mechanisms 4. This snap-fit ​​method allows the coating adhesion components 5 to be pre-prepared and dried, without requiring excessive equipment time. The two sets of connecting mechanisms 4 are connected by a connecting rope 6. Activating the electric telescopic rod 2 moves the support arm 201 upward, which in turn moves one set of connecting mechanisms 4 upward. As the tension between the two sets of connecting mechanisms 4 gradually increases, the substrate 502 of one set of coating adhesion components 5 will be separated. If the substrate 502 in the control group separates, it means that the adhesion of the test coating meets the standard. If the substrate 502 in the test group separates, it means that the adhesion of the test coating does not meet the standard. Compared with existing cross-cut and circle methods, the test results are clearer and simpler.

[0024] In order to avoid the connecting plate 401 falling directly due to the separation of the upper substrate 502, the device adopts the following technical solution: a limiting groove 102 is opened on the front of the support frame 101, a limiting slider 301 is slidably installed in the limiting groove 102, a U-shaped support fork 3 is fixedly connected to the front of the limiting slider 301, a threaded sleeve block 302 is fixedly connected to one side of the U-shaped support fork 3, and a fastening bolt 303 is installed in the threaded sleeve block 302.

[0025] By sliding the limiting groove 102 and the limiting slider 301 together, the U-shaped support fork 3 can be slidably installed on the front of the stand 101, so that the U-shaped support fork 3 is located below the upper connecting mechanism 4 and the coating adhesion component 5. In the event of separation of the upper substrate 502, the U-shaped support fork 3 can support the falling connecting plate 401 to prevent it from falling directly and damaging the equipment. The fastening bolt 303 is threaded inside the threaded sleeve block 302. When the fastening bolt 303 is tightened, its end will contact the front of the stand 101, and the friction will fix the U-shaped support fork 3 to the front of the stand 101.

[0026] In order to achieve the purpose of locking the coating adhesion component 5 in the connecting mechanism 4, the device adopts the following technical solution: The connecting mechanism 4 includes two connecting plates 401, which are symmetrically arranged. The connecting plates 401 are symmetrically fixed with locking blocks 402. One of the connecting plates 401 is fixed with a fixed mounting base 403, which is fixed with the base 1 and the support arm 201. The other connecting plate 401 is fixed with a connecting ring 404, which cooperates with the connecting rope 6. The fixed plate 501 has limit slots 503 on both sides, which cooperate with the locking blocks 402.

[0027] By using the limiting slot 503 and the locking block 402 to cooperate with each other, the two connecting plates 401 can be respectively locked above and below the coating adhesion component 5. Then, by using the connecting rope 6 and the connecting ring 404 to cooperate, the two sets of connecting mechanisms 4 can be connected together, and then the coating adhesion force of the control group and the test group can be tested.

[0028] The working principle and usage process of this utility model are as follows: First, two substrates 502 need to be bonded together with a coating beforehand. After the coating dries, they are bonded together to form a coating adhesion component 5. Then, using the cooperation of the locking block 402 and the limiting slot 503, the coating adhesion component 5 is snapped between two connecting plates 401. Connecting ropes 6 are then wrapped around two connecting rings 404. Two sets of coating adhesion components 5 are provided, one as a control group (using commercially available grade 0 or grade 1 coatings) and the other as a test group (using the coating to be tested). Activating the electric telescopic rod 2 moves the support arm 201 upwards. The upward movement of the support arm 201 moves a set of connecting mechanisms 4 upwards. As the tension between the two sets of connecting mechanisms 4 gradually increases, one set of substrates 502 of the coating adhesion component 5 will be separated. If the substrates 502 in the control group separate, it indicates that the adhesion of the test coating meets the standard. If the substrates 502 in the test group separate, it indicates that the adhesion of the test coating does not meet the standard.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
