[0049] The core of this application is to provide an adhesive selection method, system, device and medium, which can realize automatic matching of adhesive elements without manual selection, thereby improving the efficiency and accuracy of adhesive selection.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] Please refer to Figure 1 , Figure 1 A schematic diagram of a process for selecting an adhesive provided in this application, the method comprising:

[0052] S11: determining target demand elements corresponding to the target design structure according to the target design structure, the target demand elements including one or more combinations of substrate adhesion, mechanical strength, process performance, aging resistance and physical and chemical properties of the adhesive;

[0053] Specifically, in this application, the elements of the adhesive are determined as one or more combinations of substrate adhesion, mechanical strength, process performance, aging resistance and physical and chemical properties. Correspondingly, when selecting the corresponding adhesive according to the target design structure, the target demand element corresponding to the target design structure is first determined, so that the target demand element is subsequently matched with each element of each adhesive stored in the adhesive database to select an adhesive that meets the target demand element.

[0054] It should be noted that for different design structures, the types of target demand elements corresponding to them may be different, that is, not all design structures correspond to the five properties described above (substrate adhesion, mechanical strength, process performance, aging resistance and physical and chemical properties), and may only include one or a combination of more of them.

[0055] S12: Analyze and compare the target demand elements with the elements of each adhesive in the adhesive database to determine whether there is a target adhesive in the adhesive database that meets the target demand elements;

[0056] S13: If it exists, the element corresponding to the target adhesive is output in a preset format.

[0057] Specifically, after the target demand elements corresponding to the target design structure are determined, they are compared with the elements of each adhesive in the adhesive data, the adhesive that meets the target demand elements is determined as the target adhesive, and then the elements corresponding to the target adhesive are output in a preset format.

[0058] Among them, an adhesive report template may be pre-set, and the elements of the target adhesive are filled in the corresponding positions of the adhesive report template. After the template is filled in, the template is output so that the bonding engineer can refer to the template to bond the target design structure. Further, the adhesive report template may be in the form of a table, etc., which is not limited in this application.

[0059] In addition to outputting the elements corresponding to the target adhesive, the characterization information corresponding to the target adhesive may also be output, such as the serial number of the target adhesive.

[0060] It can be seen that the selection of adhesives can be achieved through the method in the present application, and the corresponding target adhesives can be automatically matched from the adhesive database according to the target demand factors of the adhesive, which can solve the problems of low efficiency and low accuracy caused by manual selection. That is, the efficiency and accuracy of adhesive selection can be improved through the method in the present application. In addition, the adhesive selection method provided in the present application can also realize the function of data collection.

[0061] Based on the above embodiments:

[0062] As a preferred embodiment, after determining that the target adhesive exists in the adhesive database, the method further includes:

[0063] Determine whether the number of target adhesives is one;

[0064] If it is one, directly proceed to the step of outputting the elements corresponding to the target adhesive in a preset format.

[0065] Specifically, when matching the target adhesive that meets the target requirement elements from the adhesive database mentioned above, considering that there may be multiple adhesive elements that meet the target requirement elements, that is, the number of determined target adhesives may be more than one, it is impossible to directly enter the step of outputting the elements of the target adhesive in a preset format.

[0066] Therefore, this embodiment aims to limit the process to directly enter the step of outputting the elements corresponding to the target adhesive in a preset format only when there is only one target adhesive determined as above, so as to ensure the accuracy of the output target adhesive.

[0067] As a preferred embodiment, after determining that the number of target adhesives is not one, the method further includes:

[0068] Calculate the matching degree between the elements of each target adhesive and the elements of the target demand;

[0069] sorting a plurality of target adhesives according to the calculated matching degrees;

[0070] Determine the final target adhesive according to the sorting results;

[0071] Output the elements corresponding to the target adhesive in a preset format, including:

[0072] Output the features corresponding to the final target adhesive in a preset format.

[0073] Specifically, when it is determined that there are more than one target adhesives matched from the adhesive database, it means that the multiple matched adhesives may meet the target requirement factor. At this time, one of the target adhesives should be selected as the final target adhesive.

[0074] First, the matching degree between the elements of each target adhesive and the target demand elements is calculated, and then multiple target adhesives are sorted according to the matching degree corresponding to each target adhesive, and the final target adhesive is determined according to the sorting result, and then the elements corresponding to the final target adhesive are output in a preset format.

[0075] When the target adhesive includes multiple elements, the matching degree is calculated by calculating the matching degree between each element and the corresponding target requirement element, and then performing weighted averaging of the matching results of the multiple elements to obtain the final matching degree result.

[0076] In addition, it should be noted that when selecting the final target adhesive based on the sorting results, it is not necessarily necessary to select the target adhesive with the best match as the final target adhesive. It can be based on other factors such as the adhesives currently available to the bonding engineer or the cost of each adhesive and the budget of the target design structure, with the sorting order as a reference to select the final target adhesive.

[0077] As a preferred embodiment, sorting multiple target adhesives according to the calculated matching degree includes:

[0078] Sort each target adhesive in descending order of matching degree;

[0079] Determine the final target adhesive based on the sorting results, including:

[0080] The target adhesive with the highest matching degree is taken as the final target adhesive.

[0081] In a specific embodiment, when there are more than one matching target adhesives, the target adhesive with the highest matching degree should be selected as the final target adhesive as much as possible to improve the reliability of bonding the target design structure.

[0082] Therefore, the specific method of sorting the target adhesives is to sort them in descending order according to the matching degree. At this time, the target adhesive with the highest matching degree is selected as the target adhesive.

[0083] As a preferred embodiment, after determining that the target adhesive does not exist in the adhesive database, the method further includes:

[0084] Conduct adhesive selection tests based on the target design structure, and select the adhesive that meets the target demand elements as the target adhesive based on the results of the selection test.

[0085] Furthermore, due to the limited data when the adhesive database is established, there may be adhesives in the adhesive database that cannot match the target demand elements. That is, when the target adhesive does not exist in the adhesive database, it is necessary to carry out adhesive selection tests based on the target design structure, and use the adhesive that meets the target demand elements as the target adhesive based on the results of the selection test.

[0086] When the target requirement factor includes multiple factors, the non-existence of the target adhesive in the adhesive database may be due to only one factor being unsatisfied or multiple factors being unsatisfied. When the number of unsatisfied factors is small, the adhesive selection test in this application may be to first derive the adhesive closest to the target requirement factor, then output the factor of this adhesive, and then conduct the adhesive selection test with this factor as a reference. The selection test may be conducted based on a simulation model or may be actually performed by an adhesive engineer, and this application is not limited here.

[0087] As a preferred embodiment, after conducting an adhesive selection test according to the target design structure and selecting an adhesive that meets the target demand elements as the target adhesive according to the results of the selection test, the method further includes:

[0088] The correspondence between the elements of the target adhesive and the target design structure is established, and the correspondence is written into the adhesive database.

[0089] Furthermore, after the adhesive selection test is carried out as mentioned above and the adhesive that meets the target demand elements is screened out, that is, after the target adhesive is screened out, a correspondence is generated between the elements of the target adhesive and the target design structure and written into the adhesive database to supplement the data in the adhesive database.

[0090] The selective testing carried out in this application to supplement the data in the adhesive database and the matching of the target adhesive from the adhesive database according to the target design structure as described above is a cyclic process. By continuously supplementing and improving the data, the data in the adhesive database becomes more comprehensive, so that in practical applications, it is easier to match the target adhesive corresponding to the target design structure from the adhesive database.

[0091] In addition, when the correspondence between the elements of the target adhesive and the target design structure is written into the adhesive data, an index corresponding to the correspondence or a serial number corresponding to the target adhesive can be generated to facilitate subsequent calls to the data in the adhesive database.

[0092] As a preferred embodiment, when the elements of the target adhesive include substrate adhesion, an adhesive selection test is carried out according to the target design structure, including:

[0093] Determine the substrate adhesion by using a corresponding first test according to the bonding type and adhesive type between substrates corresponding to the target design structure;

[0094] The first test includes a combination of one or more of a strip peel test, a tensile shear test, a 180° peel test and a T peel test.

[0095] Specifically, when the elements of the above-mentioned target adhesive include substrate adhesion, the adhesive selection test needs to test the substrate adhesion. The substrate refers to two substrates that need to be bonded with an adhesive. Specifically, when testing the substrate adhesion, different bonding types and different adhesive types have different corresponding test methods. For details, please refer to Table 1, which is a first test schematic table for testing substrate adhesion.

[0096] Table 1

[0097]

[0098]

[0099] As shown in Table 1, the adhesive types in this application may include but are not limited to 9 types, including single-component elastic adhesive, two-component elastic adhesive, single-component structural adhesive, two-component structural adhesive, contact adhesive, anaerobic adhesive, pressure-sensitive adhesive, instant adhesive and foam adhesive. The corresponding bonding types between substrates include rigid-rigid bonding, rigid-flexible bonding and flexible-flexible bonding. The corresponding first test methods are also different. For example, single-component elastic adhesive and two-component elastic adhesive use the strip peeling method to test the corresponding substrate adhesion regardless of the bonding type. Rigid-rigid bonding uses the tensile shear test method for all adhesives except single-component elastic adhesive and two-component elastic adhesive; rigid-flexible bonding uses the 180° peeling test method for all adhesives except single-component elastic adhesive and two-component elastic adhesive; flexible-flexible bonding uses the T peeling test method for all adhesives except single-component elastic adhesive and two-component elastic adhesive.

[0100] The substrate adhesion of the adhesive to be tested is tested according to the corresponding test method above, so as to select an adhesive that meets the target substrate adhesion.

[0101] Of course, the above are just some specific embodiments provided by this application, and the specific implementation is not limited to this, and this application will no longer limit it here.

[0102] As a preferred embodiment, when the elements of the target adhesive include mechanical strength, an adhesive selection test is carried out according to the target design structure, including:

[0103] The mechanical strength is determined based on the bonding type between the substrates corresponding to the target design structure and the corresponding peel failure test.

[0104] Specifically, when the elements of the above-mentioned target adhesive include mechanical strength, the mechanical strength of the adhesive needs to be tested when conducting the adhesive selection test. Specifically, when testing the mechanical strength, the corresponding test methods are different when the bonding types between the substrates are different. For details, please refer to Table 2, which is a schematic table of the test for testing the mechanical strength.

[0105] Table 2

[0106]

[0107]

[0108] As shown in Table 2, the present application provides a correspondence between different bonding types between substrates and corresponding mechanical strength indicators. For example, when the substrates are rigid-rigid overlapped, the mechanical strength to be tested is the tensile shear strength, and the corresponding test to be performed is the tensile shear test; when the substrates are rigid-rigid butt jointed, the mechanical strength to be tested is the butt tensile strength, and the corresponding test to be performed is the butt tensile test; when the substrates are rigid-flexible bonding, the mechanical strength to be tested is the 90° peel strength, 180° peel strength and floating roller peel strength, and the corresponding tests to be performed are the 90° peel, 180° peel and floating roller peel tests; when the substrates are flexible-flexible bonding, the mechanical strength to be tested is the T peel strength, and the corresponding test to be performed is the T peel test; when the substrates are sandwich structure bonding, the mechanical strength to be tested is the roller peel strength and the flat pull strength, and the corresponding tests to be performed are the roller peel test and the flat pull strength test.

[0109] The mechanical strength index of the adhesive to be tested in the target design structure is tested according to the corresponding test method, and the corresponding mechanical strength is obtained, so as to select an adhesive that meets the target mechanical strength.

[0110] Of course, the above are just some specific embodiments provided by this application, and the specific implementation is not limited to this, and this application will no longer limit it here.

[0111] As a preferred embodiment, when the elements of the target adhesive include aging resistance, an adhesive selection test is carried out according to the target design structure, including:

[0112] Evaluate various parameters corresponding to aging resistance based on the application location of the target design structure, and / or the characteristics of the adhesive seam, and / or the role of the adhesive in the target design structure and the characteristics of the environment where the adhesive is located;

[0113] Determine the aging resistance based on the evaluation of various parameters;

[0114] The characteristics of the glue seams include hidden glue seams or exposed glue seams, and the functions of the adhesive in the target design structure include bonding or sealing and filling.

[0115] Specifically, when the elements of the above-mentioned target adhesive include aging resistance, the aging resistance is divided into several parameters, and then the parameters are evaluated according to the application location of the target design structure, and / or the characteristics of the adhesive seam, and / or the role of the adhesive in the target design structure and the characteristics of the environment where the adhesive is located, to obtain evaluation results, and then the evaluation of aging resistance is obtained according to the sum of the evaluation results of each parameter. For details, please refer to Table 3, which is a schematic table of parameter analysis of aging resistance.

[0116] Table 3

[0117]

[0118] As shown in Table 3, when the target design structure is used in a train, its application location includes inside or outside the train, the characteristics of the adhesive seam include whether it is exposed or hidden, the role of the adhesive in the target design structure includes bonding or sealing and filling, and the characteristics of the environment where the adhesive is located include whether it is alternating between high and low temperatures and whether it is high temperature and high humidity, etc., in order to evaluate the fatigue degree or pH value in the aging resistance performance.

[0119] For example, when the application part is inside the car, the adhesive seam is exposed, and the adhesive function is bonding, the corresponding environmental characteristics are high and low temperature alternation and high temperature and high humidity. At this time, the parameters in the aging resistance performance are fatigue, the presence of solvents, and the possibility of acid and alkali damaging the adhesive, so as to judge the aging resistance of the adhesive to be tested. According to the above, select the adhesive that meets the target aging resistance performance.

[0120] Of course, the above are just some specific embodiments provided by this application, and the specific implementation is not limited to this, and this application will no longer limit it here.

[0121] Furthermore, when the elements of the above-mentioned target adhesive include process performance, reference may be made to Table 4, which is a schematic table of process performance indicators.

[0122] Table 4

[0123]

[0124] Specifically, 9 types of adhesives are also given as examples here. For example, the process performance indicators corresponding to the one-component elastic adhesive include four indicators: environmental requirements, gluing method, surface drying time and curing speed; the two-component elastic adhesive includes five indicators: environmental requirements, mixing parameters, gluing method, trial period and curing conditions.

[0125] After the process performance of the adhesive is determined according to the correspondence in this table, it is output in a preset format so that the bonding engineer can design the bonding target structure based on this data.

[0126] Of course, the above are just some specific embodiments provided by this application, and the specific implementation is not limited to this, and this application will no longer limit it here.

[0127] Furthermore, when the elements of the above-mentioned target adhesive include physical and chemical properties, reference may be made to Table 5, which is a schematic table of physical and chemical performance indicators.

[0128] Table 5

[0129]

[0130]

[0131] As shown in Table 5, when selecting adhesives, it is also necessary to consider the physical and chemical properties of the adhesives. The physical and chemical performance indicators corresponding to different adhesives are also different. For example, for a single-component elastic adhesive, the physical and chemical performance indicators to be considered include extrudability, density, glass transition temperature, sag, mass change rate before and after curing, hardness, volume resistivity, 100% tensile stress, tensile strength, elongation at break, and uncut right-angle tear strength. For the physical and chemical performance indicators included in other adhesives, please refer to the schematic diagram in Table 5, and this application will not repeat them here.

[0132] After the process performance of the adhesive is determined according to the correspondence in this table, it is output in a preset format so that the bonding engineer can design the bonding target structure based on this data.

[0133] Of course, the above are just some specific embodiments provided by this application, and the specific implementation is not limited to this, and this application will no longer limit it here.
