Description

Technical Field

[0001] The present application relates to the field of material testing, and in particular to a method and device for testing the base glue content of RTV anti-fouling flashover coatings based on TGA. Background Art

[0002] Pollution flashover refers to the breakdown discharge along the surface of the insulator of the external insulation components of the power transmission and transformation equipment under the combined effects of dirty and humid conditions under normal operating voltage. Pollution flashover not only includes discharges under the effects of heavy fog and drizzle, but also includes flashover forms such as snow flashover, ice flashover, and rain flashover caused by humid conditions such as snow, ice, heavy rain, and condensation. In the context of frequent pollution flashover of glass and porcelain insulators, room temperature curing silicone rubber anti-pollution flashover coating (RTV) for insulators is a widely used anti-pollution flashover product for power transmission and transformation equipment. By applying RTV on the surface of porcelain and glass insulators, the anti-pollution flashover performance of insulators is greatly improved. The component in RTV that directly plays an anti-pollution flashover role is silicone rubber. During operation, the degradation and consumption of silicone rubber provide hydrophobic migration and excellent anti-pollution flashover performance for the insulator.

[0003] The main function of RTV coating is to provide long-lasting hydrophobic migration for porcelain / glass insulators, so that the insulators can obtain long-lasting excellent anti-pollution flashover performance. For insulators with the same appearance and creepage distance, the pollution flashover voltage of the hydrophobic surface can be increased by more than 100% compared with that of the hydrophilic surface, which is equivalent to directly upgrading the anti-pollution flashover configuration of a and b pollution zones to e level, which is equivalent to a one-step configuration for most operating environments.

[0004] However, at present, the service life of RTV is generally 10 to 20 years, which is not comparable to the 50 to 100-year service life of porcelain and glass insulators. The mismatch in the service life of the two makes anti-pollution flashover coatings the shortcoming of coated porcelain / glass insulators, and leads to frequent re-coating of anti-pollution flashover coatings and capital investment. However, in recent years, with the continuous promotion of composite insulator and RTV anti-pollution flashover coating manufacturing technology, a large number of manufacturers have entered the market for silicone rubber products for power use. Due to differences in production processes and formulas among manufacturers, some of them may add calcium carbonate or other flame retardant raw materials, and their product quality is also different. The service life of some manufacturers' products after hanging is far from reaching the design value.

[0005] Therefore, for complex RTV anti-fouling flashover coatings doped with raw materials such as calcium carbonate, a test method is needed that can accurately detect the base glue content in complex samples. Summary of the invention

[0046] 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.

[0047] The acquisition, storage, use, and processing of data in the technical solution of this application comply with the relevant provisions of national laws and regulations.

[0048] Taking into account the problem that for complex RTV anti-pollution flashover coatings doped with raw materials such as calcium carbonate, a testing method that can accurately detect the base glue content in complex samples is needed, the present application provides a TGA-based RTV anti-pollution flashover coating base glue content testing method and device, which realizes the precise distinction and content measurement of the base glue and raw materials in the RTV anti-pollution flashover coating through TGA technology, thereby improving the accuracy and efficiency of the test.

[0049] In order to achieve accurate distinction and content measurement of base rubber and raw materials in RTV anti-pollution flashover coatings and improve the accuracy and efficiency of testing, the present application provides an embodiment of a method for testing the base rubber content of room temperature curing silicone rubber RTV anti-pollution flashover coatings based on thermogravimetric analysis TGA, see Figure 1 The test method for the base content of room temperature curing silicone rubber RTV anti-pollution flashover coating based on thermogravimetric analysis TGA specifically includes the following contents:

[0050] Step S101: injecting a liquid RTV anti-fouling flashover coating sample into a mold, and cutting a sample of a preset mass after curing.

[0051] Exemplarily, prepare the RTV anti-fouling flashover paint sample to be tested. First, inject the RTV anti-fouling flashover paint in liquid form into a pre-designed mold to form it in the mold. Next, perform a curing treatment under a constant temperature environment to ensure that the paint changes from a liquid state to a solid state. The cured sample needs to meet the preset quality standards, so precision cutting tools are required to cut small samples that meet the quality requirements. In addition, to ensure the accuracy of the test, the sample will be cleaned on the surface after cutting to ensure that there are no foreign impurities. The cut and cleaned samples should be placed in a dust cover to dry naturally to avoid the impact of environmental pollution on the samples.

[0052] Step S102: setting parameters for a TGA instrument, and placing a sample in the TGA instrument for testing to obtain a TGA curve.

[0053] After that, a series of parameter settings need to be made for the thermogravimetric analysis (TGA) instrument to ensure the standardization of test conditions and the accuracy of results. For example, test gas, gas flow rate, minimum test temperature and temperature rate. After the parameters are set, the prepared RTV anti-fouling flashover paint sample is automatically placed in the test area of ​​the TGA instrument to start the test process. As the temperature gradually rises, the TGA instrument will record the mass changes of the sample at different temperatures and generate a complete TGA curve. This curve characterizes the thermal decomposition behavior of the sample over the entire temperature range and is important basic data for subsequent analysis.

[0054] Step S103: different high-temperature decomposition stages are divided according to the TGA curve, and the base glue content of the RTV anti-fouling flashover coating sample is determined according to the decomposition temperature range of the base glue.

[0055] By analyzing the obtained TGA curve, the mass change characteristics of the sample in different temperature ranges can be identified. First, the TGA curve is segmented by temperature. Different components have different decomposition characteristics in these stages. For example, flame retardants mainly decompose in the low-temperature stage, base glue mainly decomposes in the medium-temperature stage, and calcium carbonate mainly decomposes in the high-temperature stage. By analyzing these decomposition stages, the decomposition of the corresponding substances in each stage can be clarified. By calculating the mass loss of the sample in this stage, the content of base glue in the RTV anti-pollution flashover coating can be determined. Finally, through these analyses, the base glue content in the RTV anti-pollution flashover coating sample can be accurately determined, thereby providing a scientific basis for the quality control and performance optimization of the coating.

[0056] From the above description, it can be seen that the test method for the base glue content of room temperature curing silicone rubber RTV anti-pollution flashover coating based on thermogravimetric analysis TGA provided in the embodiment of the present application can realize the accurate distinction and content measurement of the base glue and raw materials in the RTV anti-pollution flashover coating through TGA technology, thereby improving the accuracy and efficiency of the test.

[0057] In one embodiment of the test method of the base content of the room temperature curing silicone rubber RTV anti-pollution flashover coating based on thermogravimetric analysis TGA of the present application, the liquid RTV anti-pollution flashover coating sample is injected into the mold, and a sample of a preset mass is cut after curing, which may also specifically include the following contents:

[0058] The liquid RTV anti-fouling flashover coating sample was automatically injected into the mold, cured in a 30°C constant temperature box for 3 days, and the sample was cut after curing;

[0059] The samples were cleaned with anhydrous ethanol and placed in a dust hood to dry naturally.

[0060] Exemplarily, first, two ratios of RTV anti-fouling flashover coatings containing calcium carbonate raw materials are obtained from the manufacturer, respectively injected into pre-prepared molds, and cured in a constant temperature box at 30°C for 3 days to ensure that the coating is completely transformed from liquid to solid. After the curing is completed, the cured RTV anti-fouling flashover coating is taken out from the mold, and samples weighing 8±3 mg are cut and marked as 1# and 2#, respectively. Samples 1# and 2# represent two coatings with different ratios, but both use the same base glue and raw materials, and the shapes and structures of samples 1# and 2# are similar. The cut samples are wiped with anhydrous ethanol to remove surface dirt, and placed in a dust cover to dry naturally to ensure that the sample surface is completely dry and does not contain any residual detergent or moisture, thereby providing reliable experimental materials for subsequent TGA tests.

[0061] Preferably, in this step, the raw materials calcium carbonate, flame retardant, white carbon black and base rubber are dried respectively and recorded as raw materials A, B, C and D respectively, and the sample weight is 8±3 mg.

[0062] In one embodiment of the test method of the base content of room temperature curing silicone rubber RTV anti-fouling flashover coating based on thermogravimetric analysis TGA of the present application, the parameter setting of the TGA test instrument includes:

[0063] The test atmosphere was set to nitrogen, the gas flow rate was 40-70 ml / min, the minimum test temperature was 40 °C, the maximum test temperature was 800 °C, and the heating rate was 10 °C / min.

[0064] Before conducting a thermogravimetric analysis (TGA) test, a series of parameter settings need to be made for the experimental instrument to ensure the standardization of the test and the accuracy of the results.

[0065] First, the test environment of the TGA instrument needs to be set to a nitrogen environment. This is because nitrogen is an inert gas that can prevent the sample from undergoing oxidation reactions at high temperatures, ensuring that what is measured is the thermal decomposition process of the sample, rather than the oxidation reaction. Therefore, by setting nitrogen, more accurate and reliable test data can be obtained.

[0066] Next, set the gas flow rate to 40-70ml / min. The setting of the gas flow rate is very important. If the flow rate is too low, the sample decomposition products may not be discharged in time, affecting the test results; if the flow rate is too high, the sample decomposition rate may be accelerated, affecting the accuracy of the decomposition curve. The flow rate range of 40-70ml / min can ensure stability during the experiment, and the sample decomposition products can be taken away in time, thereby obtaining a stable TGA curve.

[0067] The minimum test temperature was set to 40°C. This temperature selection was based on the need for TGA testing to ensure that the test started at a lower temperature to cover the initial decomposition process of the sample. The starting temperature of 40°C was low enough to ensure that the test included the entire decomposition process of the sample.

[0068] The maximum test temperature is set to 800℃ to ensure that the decomposition temperature range of all components in RTV anti-fouling flashover coatings is covered. 800℃ is a relatively high temperature that ensures that all components in the sample, including high-temperature decomposed calcium carbonate, can be fully decomposed during the test, thereby obtaining a complete TGA curve.

[0069] Setting the heating rate to 10℃ / min determines the speed of temperature change. 10℃ / min is a commonly used setting that can complete the test in a shorter time while ensuring uniform temperature changes and avoiding thermal hysteresis caused by rapid temperature changes. This rate can ensure that the decomposition process of the sample can be fully displayed during the TGA test, thereby obtaining accurate decomposition temperature and mass change information.

[0070] By setting the above parameters, it can be ensured that the TGA instrument operates under the best conditions, so as to obtain accurate and reliable TGA curves, providing reliable data support for subsequent analysis and calculation of base rubber content.

[0071] In one embodiment of the test method of the base content of room temperature curing silicone rubber RTV anti-fouling flashover coating based on thermogravimetric analysis TGA of the present application, the sample is set in the TGA tester for testing to obtain a TGA curve, including:

[0072] The RTV anti-pollution flashover coating sample and the raw material are automatically subjected to TGA test respectively, and the corresponding TGA curve is determined according to the change state of their respective masses with temperature, wherein the raw materials include calcium carbonate, flame retardant, white carbon black and base rubber.

[0073] First, prepare RTV anti-pollution flashover coating samples and raw materials for comparison, including calcium carbonate, flame retardant, white carbon black and base glue. Make sure the quality of these samples and raw materials meets the preset standards (for example, the weight of each sample should be within 8±3mg).

[0074] The RTV anti-fouling flashover coating samples and raw materials are automatically placed in the sample tray of the TGA experimental instrument. Before placing, the initial mass of each sample is recorded. For example, in the exemplary experiment, the mass of the N silicone rubber sample is recorded as M 硅橡胶 Then, place the 1#RTV anti-pollution flashover paint sample and the 2#RTV anti-pollution flashover paint sample in turn, and record their masses. For example, M 1#硅橡胶 =7.67mg, M 2#硅橡胶 =7.41mg.

[0075] Similarly, each raw material (calcium carbonate, flame retardant, white carbon black and base rubber) was placed in the TGA experimental instrument and its initial mass was recorded. 原料碳酸钙 =8.33mg, M 原料阻燃剂 =8.65mg, M 原料白炭黑 =3.98mg, M 原料基胶 =6.61mg.

[0076] Start the TGA experimental instrument and automatically conduct the test. The experimental instrument will gradually increase the temperature according to the preset temperature program (for example, from 40°C to 800°C, with a heating rate of 10°C / min) and record the mass change of the sample in real time. In this way, TGA curves can be generated for each sample and raw material, which reflect the thermal decomposition behavior of the sample at different temperatures.

[0077] The TGA experimental instrument will record the mass change of each sample and raw material during the entire test process and generate the corresponding TGA curve. Figure 2As shown in Figure 1, the TGA curves of each raw material (calcium carbonate, flame retardant, white carbon black and base rubber) record their mass changes. Figure 3 As shown, these curves show the state of the mass change of samples and raw materials with temperature. For example, in the experiment, the TGA curves of 1#RTV and 2#RTV anti-fouling flashover paint samples show the mass change process from the initial mass to the increase of temperature.

[0078] By analyzing these TGA curves, the decomposition behavior of each sample and raw material at different temperature stages can be determined, thereby identifying the content of base glue and raw materials in RTV anti-pollution flashover paint samples. For example, by analyzing the TGA curves of 1# and 2#RTV anti-pollution flashover paint samples, the decomposition ratio of its base glue and each raw material at different temperature ranges can be determined.

[0079] Based on the above steps, accurate TGA curves can be obtained, providing reliable data support for subsequent parameter analysis and base rubber content calculation. This automated testing process not only improves testing efficiency, but also ensures data accuracy and repeatability.

[0080] In one embodiment of the test method for the base content of room temperature curing silicone rubber RTV anti-fouling flashover coating based on thermogravimetric analysis TGA of the present application, the different high temperature decomposition stages include a first stage, a second stage and a third stage, wherein the first stage involves the decomposition of the flame retardant, the second stage involves the decomposition of the base, and the third stage involves the decomposition of calcium carbonate;

[0081] The method of determining the base glue content of the RTV anti-fouling flashover coating sample according to the decomposition temperature range of the base glue comprises:

[0082] The base glue content of the RTV anti-pollution flashover coating sample is determined according to the decomposition temperature range of the second stage, and the content of each raw material is determined according to the mass change of the raw materials at different decomposition stages.

[0083] Among them, in the TGA curve, inorganic raw materials such as calcium carbonate and white carbon black have obvious decomposition characteristics. Figure 2 As shown, calcium carbonate has a high decomposition temperature, starting from 550°C, while white carbon black hardly decomposes in the high temperature range (800°C), showing very stable thermal stability. Based on the decomposition characteristics of these inorganic raw materials, their positions in the TGA curve can be clearly identified.

[0084] As an organic component in RTV anti-fouling flashover coatings, the decomposition temperature range of base glue is different from that of inorganic raw materials on the TGA curve. Figure 2As shown in the figure, the decomposition temperature of the base rubber is usually around the medium temperature stage (450℃ to 650℃), which does not overlap with the high temperature decomposition characteristics of inorganic raw materials (such as calcium carbonate and white carbon black). This non-overlapping property allows the decomposition characteristics of the base rubber to be clearly identified and analyzed on the TGA curve.

[0085] The flame retardant has begun to decompose at the low temperature stage (400°C to 450°C) and is almost completely decomposed before 450°C. This makes the low temperature decomposition stage of the flame retardant on the TGA curve obvious, which is distinguished from the high temperature decomposition characteristics of the base rubber and other raw materials.

[0086] By analyzing the TGA curve, the entire temperature range can be divided into three decomposition stages:

[0087] The first stage (0℃ to 450℃): mainly the decomposition stage of flame retardants.

[0088] The second stage (450℃ to 650℃): mainly the decomposition stage of the base glue.

[0089] The third stage (650℃ to 800℃): mainly the decomposition stage of calcium carbonate.

[0090] This division of decomposition stages allows the decomposition characteristics of different components within their respective temperature ranges to be clearly analyzed and identified.

[0091] Through the above-mentioned division of decomposition stages and analysis of TGA curves, the content of each component in the RTV anti-pollution flashover paint sample can be calculated. For example, from the decomposition temperature range of the second stage (450°C to 650°C) of the TGA curve in the figure, it can be calculated that the base rubber content of the 1#RTV anti-pollution flashover paint sample is 53.421%. Similarly, the content of each raw material can be calculated, including the flame retardant content, calcium carbonate content and white carbon black content. For the 2#RTV anti-pollution flashover paint sample, its base rubber content is 48.53%, and the contents of each raw material are 6% flame retardant content and 40.5% white carbon black content.

[0092] In order to achieve accurate distinction and content measurement of base glue and raw materials in RTV anti-pollution flashover coatings and improve the accuracy and efficiency of the test, the present application provides an embodiment of a testing device for the base glue content of room temperature curing silicone rubber RTV anti-pollution flashover coatings based on thermogravimetric analysis TGA for realizing all or part of the content of the testing method for the base glue content of room temperature curing silicone rubber RTV anti-pollution flashover coatings based on thermogravimetric analysis TGA, see Figure 4 The testing device for the base content of room temperature curing silicone rubber RTV anti-fouling flashover coating based on thermogravimetric analysis TGA specifically includes the following contents:

[0093] The sample preparation module 1101 is used to: inject the liquid RTV anti-fouling flashover coating sample into the mold, and cut a sample of a preset mass after curing;

[0094] The experimental test module 1102 is used to: set parameters for a TGA experimental instrument, and place a sample in the TGA experimental instrument for testing to obtain a TGA curve;

[0095] The content determination module 1103 is used to divide different high-temperature decomposition stages according to the TGA curve, and determine the base glue content of the RTV anti-fouling flashover coating sample according to the decomposition temperature range of the base glue.

[0096] According to any embodiment of the present application, the sample preparation module is specifically used for:

[0097] The liquid RTV anti-fouling flashover coating sample was automatically injected into the mold, cured in a 30°C constant temperature box for 3 days, and the sample was cut after curing;

[0098] The samples were cleaned with anhydrous ethanol and placed in a dust hood to dry naturally.

[0099] According to any embodiment of the present application, the experimental test module sets parameters for the TGA experimental instrument, specifically for:

[0100] The test atmosphere was set to nitrogen, the gas flow rate was 40-70 ml / min, the minimum test temperature was 40 °C, the maximum test temperature was 800 °C, and the heating rate was 10 °C / min.

[0101] According to any embodiment of the present application, the experimental testing module places the sample in the TGA experimental instrument for testing to obtain a TGA curve, specifically for:

[0102] The RTV anti-pollution flashover coating sample and the raw material are automatically subjected to TGA test respectively, and the corresponding TGA curve is determined according to the change state of their respective masses with temperature, wherein the raw materials include calcium carbonate, flame retardant, white carbon black and base rubber.

[0103] According to any embodiment of the present application, the different high temperature decomposition stages include a first stage, a second stage and a third stage, wherein the first stage involves the decomposition of the flame retardant, the second stage involves the decomposition of the base glue, and the third stage involves the decomposition of calcium carbonate;

[0104] The content determination module is specifically used for:

[0105] The base rubber content of the RTV anti-pollution flashover coating sample is determined according to the decomposition temperature range of the second stage, and the content of each raw material is determined according to the mass change of the raw materials at different decomposition stages. From the above description, it can be seen that the test device for the base rubber content of room temperature curing silicone rubber RTV anti-pollution flashover coating based on thermogravimetric analysis TGA provided in the embodiment of the present application can realize the accurate distinction and content measurement of the base rubber and raw materials in the RTV anti-pollution flashover coating through TGA technology, thereby improving the accuracy and efficiency of the test.
