[0038] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. For simplicity of the present disclosure, the components and the settings of particular examples are described in the following. Of course, they are merely examples and are not intended to limit the present application.

[0039] In many battery pack explosion accidents, most of the explosion accidents are caused by thermal runaway of battery monomers, which can be transmitted and spread, causing the temperature of battery monomers around the runaway battery monomers to rise rapidly, bringing huge safety hazards. Therefore, fireproof materials are needed to reduce the frequency of battery monomer thermal runaway, resulting in the overall burning and explosion of the battery pack, and to reduce the degree of spread after the battery monomer thermal runaway. It is necessary to test the heat insulation performance of different fireproof materials, and then select fireproof materials that can match different battery packs or electrical equipment. The applicant finds that the current test device is generally directly for testing the heat insulation performance of fireproof materials, and due to the limitations of test conditions and equipment during testing, it is not possible to accurately test the real performance of the fireproof materials under the multiple effects of temperature and internal pressure changes during the thermal spread process when thermal runaway occurs.

[0040] Therefore, the embodiments of the present application provide a test device for fireproof materials. Please refer to Figure 1 、 Figure 2 and Figure 4 , Figure 1 which illustrate the structure schematic diagram of the test device for fireproof materials provided by the embodiments of the present application;

[0041] Figure 2 which illustrate the partial structure schematic diagram of the test device for fireproof materials provided by the embodiments of the present application; Figure 4Partially exploded structural schematic diagram of a testing device for fireproof materials is shown. The testing device for fireproof materials is used for testing a target sample 70 of fireproof materials, and comprises a heating table 10, a temperature measuring element 20, and a gasket 30. The heating table 10 has a heating surface 11, the temperature measuring element 20 is arranged on the heating surface 11, the gasket 30 is arranged on a side of the temperature measuring element 20 away from the heating surface 11 and covers the temperature measuring element 20, and a side of the gasket 30 away from the temperature measuring element 20 is used to abut against the target sample 70. In this way, the combination of the heating table 10, the temperature measuring element 20, and the gasket 30 realizes accurate temperature control and uniform heat transfer for the target sample 70 of fireproof materials. It can be understood that a high-precision digital constant temperature platform 80 can be arranged to connect and control the heating table 10, so as to simulate the real use environment of fireproof materials, for example, the temperature is controlled to be above 700 DEG C, to ensure that the temperature is stable and uniformly distributed during the test, and to improve the reliability of the test results. At the same time, since the hardness of the target sample 70 is generally low, the gasket 30 can prevent the temperature measuring element 20 from being indented into the target sample 70 during the test, which not only protects the target sample 70, but also ensures the stability of heat transfer and the accuracy of temperature values, further improving the test precision.

[0042] Please refer to Figure 3 , Figure 3 Arrangement schematic diagram of the temperature measuring element and the gasket on the surface of the target sample in the testing device for fireproof materials is shown. In some embodiments, the number of temperature measuring elements 20 is multiple, and the multiple temperature measuring elements 20 are arranged on the heating surface 11 at intervals. Specifically, the temperature measuring element 20 can be a temperature sensing wire. The multiple temperature measuring elements 20 can simultaneously monitor the temperatures of different areas on a side of the target sample 70 facing the heating surface 11, comprehensively reflect the temperature distribution of the target sample 70, and avoid the influence of local temperature abnormalities on the test results. Secondly, through multi-point temperature measurement, the temperature uniformity of the target sample 70 can be more accurately mastered, the consistency of the test conditions is ensured, and the reliability of the test data is improved. Moreover, through the multiple temperature measuring elements 20, the temperature changes of each area on the side of the target sample 70 facing the heating surface 11 are detected in real time, local overheating or temperature unevenness problems are found in time, and the test conditions can be quickly adjusted. Especially for large-size or irregularly-shaped target samples 70, the multi-point temperature measurement design can better ensure the accuracy of the test results, so that the testing device is suitable for testing more types of fireproof materials, and the application range of the testing device is expanded.

[0043] Please refer to Figure 3In some embodiments, the number of gaskets 30 is multiple, and each temperature measuring element 20 is covered by at least one gasket 30. It can be understood that if each temperature measuring element 20 is covered by an independent gasket 30, the direct contact between the temperature measuring element 20 and the target sample 70 can be effectively avoided, and it is ensured that any temperature measuring element 20 is prevented from sinking into the target sample 70. In addition, the multiple gaskets 30 covering the temperature measuring elements 20 respectively ensure that heat is uniformly transmitted from the heating surface 11 to the target sample 70, avoids local uneven heat conduction, and improves the accuracy of the test results. Moreover, the multiple gaskets 30 are used in cooperation with the multiple temperature measuring elements 20, which can better support the multi-point temperature measurement design, comprehensively monitor the temperature distribution of the target sample 70 towards the side of the heating surface 11, and improve the test precision. At the same time, each temperature measuring element 20 is independently covered by a gasket 30, which reduces the mutual interference between the temperature measuring elements 20, and ensures the stability and reliability of the temperature data in the test process.

[0044] It can be understood that the gasket 30 of the present application should be a stainless steel sheet, or a gasket 30 that satisfies the conditions of resisting temperature higher than 700°C, good thermal conductivity, and high hardness, so as to truly simulate the eruption temperature of battery cell thermal runaway, and effectively prevent the temperature measuring element 20 from sinking into the target sample 70 under simulated pressure.

[0045] In some embodiments, the thickness of the gasket 30 is 1-2 mm. Specifically, the thickness of the gasket 30 can be any one of 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, or a range value between any two of them. Within this range, the thickness of the gasket 30 is moderate, which can effectively transmit heat, and will not increase the heat dissipation area due to excessive thickness, so as to ensure that the temperature of the heating surface 11 can be efficiently and uniformly transmitted to the target sample 70. At the same time, the thickness of 1-2 mm ensures that the gasket 30 can provide sufficient mechanical strength, which can support and protect the target sample 70, and avoid damage or sinking of the temperature measuring element 20 into the sample due to pressure. The thickness of 1-2 mm makes the thickness of the gasket 30 slightly larger than the diameter of the temperature measuring element 20, which avoids heat loss due to excessive thickness, reduces energy loss in the heat conduction process, reduces thermal resistance, and ensures the accuracy of the test data.

[0046] Please refer again to Figure 3 and Figure 4In some embodiments, the testing device further comprises a fixing member 40, and the temperature measuring member 20 and the gasket 30 are connected through the fixing member 40. Specifically, the fixing member 40 firmly connects the temperature measuring member 20 and the gasket 30, prevents the temperature measuring member 20 from being displaced or loosened due to the pressure of the target sample 70 or the vibration of the testing device during the testing process, and ensures the stability of the testing data. Meanwhile, the fixing member 40 makes the installation of the temperature measuring member 20 and the gasket 30 more convenient, facilitates the disassembly and maintenance, and reduces the maintenance cost and the use difficulty of the testing device. In addition, the fixing member 40 ensures the close contact between the temperature measuring member 20 and the gasket 30, reduces the thermal resistance, improves the heat transfer efficiency, and thus improves the accuracy of the temperature monitoring and the reliability of the testing result. Therefore, the fixing member 40 can be a fixing member 40 or other fixing member with good high-temperature resistance, good thermal conductivity and good fixing effect.

[0047] Please refer to Figure 1 and Figure 2 In some embodiments, the testing device further comprises a cover plate assembly 50 arranged towards the gasket 30, for enabling the target sample 70 to be accommodated between the gasket 30 and the cover plate assembly 50. Specifically, the cover plate assembly 50 cooperates with the gasket 30 to firmly fix the position of the target sample 70, prevents the target sample 70 from being displaced or loosened during the testing process, and ensures the stability of the testing condition. Meanwhile, the cover plate assembly 50 can apply uniform pressure to the target sample 70, so that the target sample 70 is in close contact with the gasket 30, the thermal resistance is reduced, the uniformity of the heat transfer is improved, and the accuracy of the testing result is improved. That is, the present application can simulate the pressure on the fireproof material in the real environment through the cover plate assembly 50, so that the testing result is more accurate.

[0048] Please refer to Figure 1 and Figure 2 Please refer to Figure 5 and Figure 6 , Figure 5 Fig. 2 schematically shows the structure of a second plate body of the testing device for fireproof materials according to an embodiment of the present application; Figure 6Partially sectional schematic view of the first plate body, the second plate body and the third plate body of the testing device for the fireproof material is shown. In some embodiments, the cover plate assembly 50 comprises a first plate body 51, a second plate body 52 and a third plate body 53; the first plate body 51 is arranged towards the gasket 30; the temperature measuring piece 20 is further arranged on the side of the first plate body 51 away from the gasket 30; the second plate body 52 is arranged on the side of the temperature measuring piece 20 away from the first plate body 51, and the second plate body 52 is provided with a receiving groove 521, and the temperature measuring piece 20 is received in the receiving groove 521; the third plate body 53 is arranged on the side of the second plate body 52 away from the first plate body 51. Specifically, the combined design of the first plate body 51, the second plate body 52 and the third plate body 53 improves the overall mechanical strength of the cover plate assembly 50, which can withstand greater pressure and ensure the stability of the sample 70 during the test. Among them, the first plate body 51 directly contacts the sample 70, which can uniformly distribute the pressure to the surface of the sample 70, avoid local pressure being too large or too small, and improve the accuracy of the test results; if the temperature measuring piece 20 is arranged on the heating surface 11, which is equivalent to arranging the temperature measuring piece 20 on the hot surface of the target sample 70, then arranging the temperature measuring piece 20 on the side of the first plate body 51 away from the gasket 30 is equivalent to arranging the temperature measuring piece 20 on the cold surface of the target sample 70, which can measure the temperature of the cold surface and the hot surface of the target sample 70 at the same time. Similarly, the number of temperature measuring pieces 20 arranged on the side of the first plate body 51 away from the gasket 30 can also be set to multiple, and the beneficial effects can be referred to the description above, which will not be repeated here. On this basis, the second plate body 52 is provided with a receiving groove 521 for receiving the temperature measuring piece 20, so as to avoid the contact between the temperature measuring piece 20 and the third plate body 53, so that the temperature measuring piece 20 only contacts the side of the first plate body 51 away from the gasket 30, which is equivalent to only contacting the cold surface of the target sample 70, avoiding the interference of the receiving groove 521 or the third plate body 53 on the cold surface temperature measurement. It can be understood that the temperature measuring piece 20 can also be tightly connected with the first plate body 51 through the fixing piece 40, and at the same time, the temperature measuring piece 20 is effectively isolated from the third plate body 53. The third plate body 53 is arranged on the side of the first plate body 51 away from the gasket 30, which can effectively isolate high temperature heat, reduce heat loss to the outside, and at the same time protect the operator from high temperature. In addition, the split design of the cover plate assembly 50 makes the installation, disassembly and maintenance more convenient, reduces the use cost and improves the test efficiency.

[0049] In some embodiments, the first plate body 51 and the second plate body 52 are aluminum plates, and the third plate body 53 is a silicate plate. Specifically, the first plate body 51 and the second plate body 52 are aluminum plates, and aluminum has excellent heat conduction performance, which can quickly and uniformly transmit heat from the target sample 70 through the first plate body 51 to the cold surface temperature measuring element 20, ensuring the uniformity of temperature distribution during the test and improving the test accuracy. The third plate body 53 is a silicate plate, and silicate material has excellent heat insulation performance, which can effectively block the diffusion of high-temperature heat to the outside, reduce heat loss, at the same time, protect the operator from high temperature, and improve the test safety. It should be noted that the thickness of the first plate body 51 can be 0.5-1.5mm, and the thickness of the third plate body 53 can be 20-60mm, and the mass value of the third plate body 53 is 470-490g. Of course, the number of the first plate body 51 and the second plate body 52 can be set to multiple, so that the total thickness of the plurality of first plate bodies 51 and the second plate bodies 52 satisfies 0.5-1.5mm, the total thickness of the plurality of third plate bodies 53 satisfies 20-60mm, and the total mass value of the plurality of third plate bodies 53 satisfies 470-490g.

[0050] Please refer again to Figure 1 In some embodiments, the test device further comprises a pressurizing assembly 60 arranged on the side of the cover plate assembly 50 away from the gasket 30. Specifically, the pressurizing assembly 60 can apply uniform pressure to the cover plate assembly 50, so that the target sample 70 is in close contact with the gasket 30, reducing thermal resistance, ensuring the uniformity of heat transfer, and improving the accuracy of test results. At the same time, through the pressure applied by the pressurizing assembly 60, the external pressure conditions suffered by the fireproof material in the real environment can be simulated, so that the test results have more reference value, for example, the pressure received by the target sample 70 is controlled to 5000-25000N. In addition, the pressurizing assembly 60 can fix the position of the cover plate assembly 50 and the target sample 70, preventing the target sample 70 from shifting or loosening during the test, and ensuring the stability of the test conditions.

[0051] Please refer again to Figure 1In some embodiments, the pressurizing assembly 60 comprises a pressing plate 61, a pressure column 62, and a pressure machine 63; wherein the pressing plate 61 is arranged on the side of the cover plate assembly 50 away from the gasket 30, the pressure column 62 is connected with the pressing plate 61, and the pressure machine 63 is connected with the pressure column 62. Specifically, the pressure machine 63 transmits pressure to the pressing plate 61 through the pressure column 62, which can accurately control the pressure applied to the cover plate assembly 50 and the sample 70, ensuring the stability and consistency of the test conditions. Secondly, the pressing plate 61 has a large contact area with the cover plate assembly 50, which can uniformly distribute the pressure to the surface of the target sample 70, avoiding excessive or insufficient local pressure, and improving the accuracy of the test results. That is, the embodiments of the present application can simulate the external pressure conditions of the fireproof material in the real environment by adjusting the pressure of the pressure machine 63, improving the accuracy of temperature monitoring and the reliability of test data.

[0052] Next, the use method of the test device of the present application is described.

[0053] Firstly, a target sample 70 of fireproof material with a thickness of 0.5-5.0 mm is taken, and the cold face and the hot face are marked. Three temperature measuring pieces 20 are arranged on the hot face of the target sample 70, and the three temperature measuring pieces 20 are fixed by the fixing piece 40 and placed on the gasket 30 with a thickness of 1.0-2.0 mm.

[0054] Secondly, a first plate body 51 with a thickness of 0.5-1.5 mm is taken and overlapped on the target sample 70 after the first step, and the three temperature measuring pieces 20 are fixed by the fixing piece 40 and placed on the side of the first plate body 51 away from the target sample 70.

[0055] Thirdly, a second plate body 52 with a thickness of 0.5-1.5 mm is taken and overlapped on the side of the temperature measuring piece 20 away from the first plate body 51 in the second step, and the temperature measuring piece 20 is placed in the accommodating groove 521. The three temperature measuring pieces 20 can be optionally fixed by the fixing piece 40.

[0056] Fourthly, two third plate bodies 53 with a thickness of 10-30 mm are taken and placed in an oven for a certain time. After drying, the two third plate bodies 53 are taken out, and each third plate body 53 has a mass value of 235-245 g. Then, the two third plate bodies 53 are overlapped on the side of the first plate body 51 away from the temperature measuring piece 20 in the third step.

[0057] Fifthly, the target sample 70 after the above steps is fixed under the pressing plate 61, and then the pressure value of the pressure machine 63 is adjusted to 5000-25000 N. The target sample 70 is slowly lowered to accurately cover the heating surface 11 of the heating table 10 at a certain speed, and the corresponding hot surface temperature is set according to the test requirements of the target sample 70, which can be 700-1000℃. The corresponding test time can be 5-20 min.

[0058] In the sixth step, after the above test steps are completed, the cold face temperature and the hot face temperature of the target sample 70 are recorded, and the cold-hot face temperature difference is calculated to determine the heat insulation performance of the target sample 70 under certain test temperature and pressure conditions.

[0059] In summary, the present application realizes precise temperature control and uniform heat transfer of the target sample 70 of the fireproof material through the combined design of the heating table 10, the temperature measuring piece 20 and the gasket 30. It can be understood that the present application can set a high-precision digital constant temperature platform to connect and control the heating table 10 to realize the simulation of the real use environment of the fireproof material, for example, the temperature is controlled to above 700℃, to ensure that the temperature is stable and uniformly distributed during the test, and to improve the reliability of the test results. At the same time, since the hardness of the target sample 70 is generally low, the gasket 30 can prevent the temperature measuring piece 20 from being indented into the target sample 70 during the test, which not only protects the target sample 70, but also ensures the stability of heat transfer and the accuracy of temperature value, further improving the test precision.

[0060] The above describes in detail the test device for the fireproof material provided by the embodiments of the present application, and the principles and implementation manners of the present application are described by applying specific examples. The above embodiment description is only used to help understand the technical solutions and core ideas of the present application; those skilled in the art should understand that the technical solutions recorded in the above embodiments can be modified or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
