Description

Technical Field

[0001] The utility model relates to the technical field of self-repairing tires, in particular to a sealing test device for self-sealing glue. Background Art

[0002] Tires mainly rely on the closed chamber formed between the airtight layer rubber and the rim to maintain tire pressure and ensure tire safety and comfort. When a tire is driving on the road, it may sometimes be pierced by a nail. After the nail penetrates the tire's airtight layer, it is easy to cause the internal air pressure of the tire to drop sharply, causing the car to lose control and causing a traffic accident. In response to the above situation, many large manufacturers on the market have developed self-repairing tires. After being pierced by a nail, the tire can repair itself, and the air pressure will not drop significantly, and can basically be maintained above 90%.

[0003] The self-repairing function of the tire can be achieved by coating the self-sealant on the inner wall of the tire to form a self-sealant layer. The self-sealant layer formed by the self-sealant is used as a functional material for ordinary pneumatic tires to resist nail puncture. When a nail pierces the tire with the self-sealant layer, the self-sealant can wrap the nail to prevent the tire from leaking. After the nail is pulled out, the self-sealant can seal the nail hole to prevent the tire from leaking. There are many existing designs and developments on self-sealants, mainly focusing on the design of self-sealant components, preparation methods, etc. For example, CN117229730A discloses a self-sealant and its preparation method and application, and CN117866342A discloses a self-sealing composition and its use in tires.

[0004] When designing and developing tire self-sealing glue, it is necessary to test the self-sealing repair effect of the self-sealing glue after the nail is inserted. If the test is directly conducted on the tire, the time and economic cost are too high, so it is necessary to develop and design a simple device that can directly test the self-sealing property of the self-sealing glue. In view of the above problems, a device for testing the sealing properties of the self-sealing glue is needed. Utility Model Content

[0087] This embodiment further provides a working method of a sealing test device for a self-sealing adhesive, the working method comprising the following steps:

[0088] S1, the open sealed can body 1 and the cover body 2 are in a separated state, and the sealing gasket sample 4 is placed between the open sealed can body 1 and the cover body 2, and the sealing gasket sample 4 corresponds to the edge pressing groove 3;

If the air pressure drops significantly (drops to 90% or less of the pressure before inserting the nail 10), the self-sealing property of the self-sealant is poor. Otherwise, the self-sealing property of the self-sealant is good.

[0094] Example 2

[0095] like Figure 6 As shown, this embodiment, based on Embodiment 1, further includes the following settings:

[0096] A camera 15 is disposed on the outer side of the open sealed can body 1 and is opposite to the opening of the bottom cover 13 . The camera 15 is used to photograph the situation inside the open sealed can body.

[0108] In addition, in the present embodiment, only one through hole 5 is provided, and the diameter of the through hole 5 is relatively large. Here, the large diameter means that a plurality of nails 10 can be passed through at the same time.

[0111] In this embodiment, the nail rack 9 also plays a role of safety and protection, specifically:

[0112] The nail 10 is provided with an annular protrusion 18, the diameter of which is larger than the diameter of the nail 10, the nail rack 9 is provided with a through hole matching the diameter of the nail 10, the diameter of which is smaller than the diameter of the annular protrusion 18, and the annular protrusion 18 is located between the nail rack 9 and the cover 2. This can avoid the danger caused by the high pressure in the open sealed can body 1 being released after the nail 10 is inserted due to the poor self-sealing property of the self-sealing glue of the sealing gasket sample 4, and after the nail 10 is rushed out, the annular protrusion 18 can be limited by the nail rack 9 to prevent the nail 10 from flying out at will.

[0113] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work.
