Description

Technical Field

[0001] This utility model belongs to the technical field of water immersion devices, and in particular relates to a device for testing the moisture-proof performance of resin adhesives. Background Technology

[0002] Moisture resistance testing mainly assesses the stability and protective ability of adhesives in humid environments. The main testing methods include water absorption rate testing and immersion testing. Regardless of whether it is water absorption rate testing or immersion testing, the product to be tested needs to be submerged below the water surface for a period of time before being taken out for observation and testing to obtain moisture resistance performance parameters. However, in the process, multiple sets of samples cannot be processed in batches, and manual operation is cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a device for testing the moisture resistance of resin adhesives. Through the hierarchical design of support rods and baffles, it ensures that the test plate is stably submerged after horizontal insertion. The gaps between the baffles enable batch fixing of multiple test plates, thereby improving testing efficiency and solving the problems raised in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a device for testing the moisture-proof performance of resin adhesives, comprising a support frame for placing a test plate; a cured resin adhesive layer is formed on the test plate; and a water tank, wherein during testing, the support frame is placed in the water tank and the test plate is submerged below the water surface; the support frame includes brackets at both ends, a support structure composed of multiple support rods and two stop rods are connected between the two brackets; the support structure is located between the two stop rods, and the height of the stop rods is higher than the height of the support rods; several spacers are connected between the two stop rods; adjacent spacers form a gap for inserting the test plate.

[0006] Furthermore, the test plate is a smooth ceramic plate, plastic plate, or glass plate. The smooth surface ensures uniform coating of the resin adhesive and consistent thickness of the cured layer, guaranteeing the comparability of water absorption test data and facilitating complete cleaning of the cured layer after testing.

[0007] Furthermore, the top of the support is connected to a U-shaped handle, which makes it easy to lift the entire support frame out of the water tank, avoiding contamination or data deviation caused by human hand contact with the sample.

[0008] Furthermore, the bottom of the bracket is provided with protruding parts on both sides, and a pair of vertical rods are provided at both ends of the water tank. The top of the vertical rods is provided with a U-shaped support block. When the support frame is lifted from the water tank and removed from the water surface, the protruding parts are controlled to rest on the support block. After the support frame is removed from the water surface, it is suspended in the air to drain water, which accelerates the dripping of water droplets and avoids the detection plate from contacting the water surface again, thus ensuring the accuracy of the data during the draining stage.

[0009] This utility model has the following beneficial effects:

[0010] This invention uses a hierarchical design of support rods and stop rods to ensure that the test plate is stably submerged after horizontal insertion, and the gaps between the rods allow for batch fixing of multiple test plates, thereby improving testing efficiency.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figure 1 and 6 As shown, this utility model is a resin adhesive moisture-proof performance testing device, including a support frame 2 and a water tank 1. When conducting a water absorption rate test, a resin adhesive of a certain thickness is coated on a test plate 3, and after curing, a resin adhesive cured layer 30 is formed. When conducting a water immersion test, a cover plate is glued to the end of a box body by resin adhesive.

[0027] Specifically, such as Figure 2The support frame 2 includes brackets 21 at both ends, a support structure consisting of multiple support rods 22 and two stop rods 23 connected between the two brackets 21; the support structure is located between the two stop rods 23, and the height of the stop rods 23 is higher than the height of the support rods 22; several spacers 25 are connected between the two stop rods 23; adjacent spacers 25 form a gap for the insertion of the test plate 3 and the box body; after assembly, the support frame 2 is placed in the water tank 1, and the test plate 3 and the box body are submerged below the water surface of the water tank 1. After a period of time, it is taken out for observation and testing to determine the water absorption rate of the resin adhesive curing layer 30 and whether there is water leakage inside the box body; a U-shaped handle 24 is connected to the top of the bracket 21 to facilitate the control of the movement of the support frame 2 during use.

[0028] The water absorption rate of the resin adhesive cured layer 30 includes: weighing the test plate 3, the weight of which is M1; weighing the test plate 3 with the resin adhesive cured layer 30 formed, the weight of which is M2; and weighing the resin adhesive cured layer 30 and the test plate 3 together after water absorption, the weight of which is M3; and then the water absorption rate at this time is (M3-M2) / (M2-M1); the test plate 3 is a ceramic plate with a smooth surface.

[0029] Anhydrous copper sulfate granules are placed inside the box. Both the box and the cover are made of colorless and transparent material. When using the product, the presence of water leakage can be confirmed by observing whether the copper sulfate granules change color.

[0030] Specifically, such as Figure 3-4 As shown in Figures 7 and 8, in order to control the water droplets adhering to the detection plate 3 and the resin adhesive curing layer 30 to drain after the support frame 2 is removed from the water tank 1, protruding parts 26 are provided on both sides of the bottom end of the support 21, and a pair of vertical rods 10 are provided at both ends of the water tank 1, with a U-shaped support block 11 at the top of the vertical rods 10; when the support frame 2 is lifted upward from the water tank 1 and removed from the water surface, the protruding parts 26 are controlled to rest on the support blocks 11, which facilitates the drainage.

[0031] When the support frame 2 is placed inside the water tank 1, the two vertical rods 10 located on one side of the water tank 1 extend out from the gap between the U-shaped handle 24 and the bracket 21.

[0032] During immersion testing, to prevent the box from floating, such as Figure 9 It is also equipped with a counterweight plate 27, and the two ends of the counterweight plate 27 form bent parts 271 respectively. The counterweight plate 27 rests on the support 21.
