Description

Technical Field

[0001] This invention relates to the field of superhydrophobic coatings for anti-flashover of power transmission lines, and particularly to a comprehensive evaluation method, system, equipment, and medium for the anti-aging, high weather resistance, and long-lasting durability of superhydrophobic anti-flashover coatings. Background Technology

[0002] Insulators, as key components of power transmission and transformation lines, are exposed to complex outdoor environments for extended periods, making them susceptible to flashover accidents caused by factors such as smog, humidity, and industrial pollution. This can lead to large-scale power outages, resulting in significant economic losses and social impacts. Superhydrophobic anti-flashover coatings, through the construction of micro-nano composite rough structures and low surface energy chemical modifications, achieve a self-cleaning function similar to the "lotus leaf effect," effectively inhibiting dirt deposition and moisture adhesion, making them a powerful tool for solving insulator flashover problems. However, because anti-flashover coatings are easily affected by harsh environments such as wind, snow, dust, acid rain, and industrial oil, the coatings age rapidly. This manifests as a decrease in contact angle and an increase in roll-off angle after chemical erosion of the coating's microstructure surface, leading to a decline in hydrophobic properties. Consequently, the coating's anti-flashover durability is not strong, and its anti-pollution ability often begins to decline significantly after a period of time following application, sometimes even failing completely within 2-3 years.

[0003] However, current evaluation methods often focus on single microscopic performance indicators (such as contact angle attenuation and salt density changes), lacking a synergistic consideration of multiple indicators affecting the service life of coatings under the coupled effects of various factors. Furthermore, the correlation, weight allocation, and long-term effectiveness verification standards of the evaluation indicators are inconsistent, making it difficult to comprehensively reflect the overall performance of coatings under actual working conditions. In general, the lack of a comprehensive evaluation model for assessing the anti-aging, high weather resistance, and long-term durability of superhydrophobic anti-flashover coatings makes it difficult to make scientific and reasonable judgments regarding coating optimization and service life.

[0004] Therefore, a method is proposed that integrates the physicochemical properties, mechanical stability, anti-flashover effectiveness, and aging degradation law of anti-flashover coatings, incorporating the coating's anti-aging performance, high weather resistance, and long-term durability into a comprehensive evaluation system with multiple indicators, multiple weights, quantifiability, and predictability. Summary of the Invention

[0005] In view of the aforementioned difficulties in evaluating the long-term weather resistance of existing coatings, this invention is proposed.

[0006] Therefore, this invention provides a comprehensive evaluation method, system, equipment, and medium for the anti-aging, high weather resistance, and long-term durability of superhydrophobic anti-flashover coatings. This addresses the problem that existing anti-flashover coating evaluation methods rely on single indicators (measuring only contact angle, etc.) and lack a systematic quantitative evaluation standard that considers the coupling of multiple factors such as anti-aging, weather resistance, and long-term durability. This makes it difficult to accurately predict the service life of the coating under complex actual working conditions (such as the combined effects of salt spray, ultraviolet radiation, and acid rain), thus hindering scientific selection and maintenance decisions.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: In a first aspect, the present invention provides a comprehensive evaluation method for the anti-aging, high weather resistance, and long-lasting durability of superhydrophobic anti-flashover coatings, including: The coating was subjected to accelerated aging tests, and an anti-aging performance evaluation sub-model was constructed by combining the analytic hierarchy process (AHP) to obtain the anti-aging performance index.

[0011] As a preferred embodiment of the comprehensive evaluation method for the anti-aging, high weather resistance, and long-lasting durability of the superhydrophobic anti-flashover coating described in this invention, the method involves: constructing a long-lasting durability performance evaluation sub-model based on full-cycle data from accelerated aging tests to obtain a long-lasting durability performance index, including: By accelerating aging tests, performance degradation data over the entire lifecycle is obtained, and long-lasting standardized scores and long-lasting combination weights are derived. The long-lasting performance index is obtained by combining long-lasting and durable combined weights with long-lasting and durable standardized scores.

[0012] As a preferred embodiment of the comprehensive evaluation method for the anti-aging, high weather resistance, and long-lasting durability of the superhydrophobic anti-flashover coating described in this invention, the method includes: constructing a graded evaluation ladder function based on a comprehensive performance index to obtain the comprehensive performance graded evaluation results of the coating and the corresponding optimization decision instructions, including: Set a first threshold and a second threshold, wherein the first threshold is less than the second threshold; If the overall performance index is less than the first threshold, the output evaluation result is low, and a material selection adjustment instruction is generated. If the first threshold ≤ comprehensive performance index < first threshold, the output evaluation result is medium, and a process optimization instruction is generated; If the overall performance index is greater than or equal to the second threshold, the output evaluation result is high, and a selection application instruction is generated.

The subjective weights of anti-aging, high weather resistance, and long-lasting effect were determined by the analytic hierarchy process. Based on objective and subjective weights, the combined weights for anti-aging, high weather resistance, and long-lasting effects are calculated.

[0014] Secondly, this invention provides a comprehensive evaluation system for the anti-aging, high weather resistance, and long-lasting durability of superhydrophobic anti-flashover coatings, comprising: The anti-aging module is used to conduct accelerated aging tests on the coating, and combined with the analytic hierarchy process (AHP), constructs a sub-model for evaluating anti-aging performance to obtain the anti-aging performance index.

Attached Figure Description

[0018] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the following description of the embodiments will be briefly introduced. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] Figure 1 This is a schematic diagram of the overall process of the comprehensive evaluation method for the anti-aging, high weather resistance and long-lasting durability of the superhydrophobic anti-fouling flashover coating according to an embodiment of the present invention. Detailed Implementation

[0020] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] Example 1, referring to Figure 1 As an embodiment of the present invention, a comprehensive evaluation method for the anti-aging, high weather resistance, and long-lasting durability of superhydrophobic anti-flashover coatings is provided, comprising: S100: The coating is subjected to accelerated aging tests, and combined with the analytic hierarchy process (AHP), a sub-model for evaluating anti-aging performance is constructed to obtain the anti-aging performance index. S200: By accelerating aging tests and combining regional environmental characteristics, a high weather resistance performance evaluation sub-model is constructed to obtain the high weather resistance performance index; S300: Based on the full-cycle data of accelerated aging tests, a long-term durability performance evaluation sub-model is constructed to obtain the long-term durability performance index; S400: The anti-aging performance index, high weather resistance performance index and long-lasting performance index are weighted and integrated to construct a comprehensive performance index model and obtain the comprehensive performance index. S500: Based on the comprehensive performance index, a graded evaluation ladder function is constructed to obtain the comprehensive performance graded evaluation results of the coating and the corresponding optimization decision instructions.

[0022] It should be noted that the anti-flashover coating of transmission line insulators faces extreme environmental challenges during long-term outdoor service. It not only withstands high-voltage electric fields but is also constantly subjected to the combined erosion of ultraviolet radiation, acid rain corrosion, thermal shock, and dirt deposition. Over time, the micro- and nano-structures on the coating surface wear down, and low-surface-energy substances gradually decompose or are lost, leading to "lotus effect" failure. However, the micro-aging process of the coating is slow and insidious, and relying solely on static contact angle tests in the laboratory often fails to reflect its true degradation trend under complex dynamic environments. Therefore, establishing a model capable of simulating complex operating conditions and quantitatively predicting the coating's performance throughout its entire life cycle is particularly important.

[0023] Therefore, to address the aforementioned problems, through steps S100-S500, sub-models for evaluating the coating's anti-aging performance, high weather resistance, and long-lasting durability are constructed respectively. The evaluation results of these three dimensions—anti-aging evaluation index, high weather resistance evaluation index, and long-lasting durability evaluation index—are integrated to construct a comprehensive performance index model, ultimately achieving a quantitative and graded evaluation of its comprehensive performance.

[0024] Example 2, refer to Figure 1 This is one embodiment of the present invention. Based on the above embodiment, a comprehensive evaluation method for the anti-aging, high weather resistance, and long-lasting durability of superhydrophobic anti-flashover coatings is provided.

[0025] In this embodiment of the application, step S100 involves conducting accelerated aging tests on the coating, and using the analytic hierarchy process (AHP) to construct a sub-model for evaluating anti-aging performance, thereby obtaining an anti-aging performance index. This includes the following steps A1-A4: A1: The surface resistivity and adhesion of the anti-flashover coating were tested in an accelerated aging test to obtain a standardized anti-aging score. Specifically, a sub-model for evaluating the anti-aging performance of coatings is constructed by describing the coating's inherent ability to resist irreversible degradation of its chemical structure (molecular chain breakage, cross-linking, oxidation) and physical structure (microstructure) due to environmental stress.

[0026] Therefore, an accelerated aging test was designed, implementing a systematic cycle of "stress application → performance monitoring → data analysis." Coating samples were placed in an accelerated aging test chamber and subjected to cyclic exposure under set intensified stress conditions. Samples were taken out at predetermined time intervals (e.g., every 100, 300, 500, and 1000 hours) for performance testing. The sampling points needed to be sufficiently dense to capture the performance degradation trajectory.

[0027] Furthermore, accelerated aging tests were conducted to examine the decline in surface resistivity and adhesion of the coating. Initial values ​​were mapped to the highest score (e.g., 1 or 100), and the failure threshold was mapped to the lowest score. A standardized anti-aging score was obtained by fitting the mapping using either a linear or nonlinear function. , representative indicators The standardized score at aging time t.

[0028] A2: The surface resistivity and adhesion of the anti-flashover coating were tested in an accelerated aging test to obtain the anti-aging combination weight. Specifically, accelerated aging tests are conducted using the anti-flashover coating to obtain an accelerated aging test data matrix. The weights are then objectively determined using the variability and discriminative power of the test data itself, resulting in objective weights.

[0029] Referring to Table 1, each row represents test groups at different aging time points (e.g., 0h, 500h, 1000h, 2000h) or different stress levels. Each column represents the key performance parameters to be evaluated, namely surface resistivity and adhesion. Each element in the matrix is ​​the specific value of a certain performance parameter measured at a specific aging time point / condition.

[0030] Table 1

[0031] Furthermore, the Analytic Hierarchy Process (AHP) is employed: the subjective weights are determined by quantifying the experts' assessment of the relative importance of surface resistivity and adhesion.

[0032] It should be noted that surface resistivity directly determines the insulation capability of the coating under polluted and wet conditions, and is a core functional indicator for preventing leakage current and flashover. Its failure directly leads to the loss of anti-flashover function. Adhesion is the fundamental guarantee for the physical integrity and long-term service of the coating. Without adhesion, the coating will peel off, and its resistivity will be meaningless. However, functional failure (decreased resistivity) may usually occur before catastrophic physical failure (complete peeling).

[0033] In an optional implementation, the subjective weights determined in step S100 using the Analytic Hierarchy Process (AHP) can also employ a best-worst approach. For example, experts first determine an "optimal index" and a "worst index" from an evaluation index system that includes anti-aging and high weather resistance. Then, only the optimal index is compared pairwise with all other indices, and all other indices are compared with the worst index. A nonlinear programming model that minimizes the maximum absolute difference is constructed, and solving this model yields the optimal subjective weights for each index.

[0034] In another optional implementation, the subjective weights determined in step S100 using the Analytic Hierarchy Process (AHP) can also employ a modified Delphi method, for example: conducting multiple rounds of anonymous questionnaires through a panel of experts in the coating field. In the first round, experts directly score the importance of each indicator (0-10 points); the coefficient of variation of the first round scores is calculated. If the coefficient of variation exceeds a preset threshold, the statistical results (mean, quartiles) are fed back to the experts for a second round of revising scores, until the Kendall coefficient of harmony is greater than 0.7, indicating that the experts have reached a consensus. Finally, the arithmetic mean of the scores for each indicator is taken and normalized as the subjective weight.

[0035] Furthermore, based on objective and subjective weights, a combined weighting for anti-aging is obtained. The expression is:

[0036] In the formula, Subjective weighting for anti-aging; As an objective weight for anti-aging.

[0037] A3: The anti-aging performance index is obtained by combining the anti-aging combination weights with the standardized anti-aging score; Specifically, constructing an anti-aging performance index The expression is:

[0038] In this embodiment of the application, step S200 involves constructing a high weather resistance performance evaluation sub-model by accelerating aging tests and combining regional environmental characteristics to obtain a high weather resistance performance index, including the following steps B1-B3: B1: Hydrophobic migration and recovery rate were tested through accelerated aging tests to obtain a high weather resistance standardized score and a high weather resistance combination weight; Specifically, high weather resistance refers to the ability of the anti-flashover coating to maintain its initial functions (superhydrophobicity and insulation) under the alternating or synergistic effects of various outdoor climatic factors (UV, temperature, humidity, pollution, precipitation, etc.).

[0039] Accelerated aging tests were conducted to examine the degradation of the coating's hydrophobic migration and recovery rate, and a standardized score for high weather resistance was determined. , representative indicators Aging time Standardized score at the time.

[0040] Similarly, the weight of the high weather resistance combination is determined by adopting the same method as obtaining the weight of the anti-aging combination.

[0041] B2: The high weather resistance performance index is obtained by combining the high weather resistance combination weight with the high weather resistance standardized score; Specifically, constructing a high weather resistance index The expression is:

[0042] In the formula, The weighting is for high weather resistance.

[0043] B3: Based on the environmental characteristics of a specific region, a regional stress weight vector is introduced to obtain the high weather resistance index of the specific region. Specifically, due to the different dominant environmental stresses in different regions (e.g., salt spray in coastal areas and acid spray in industrial areas), a regional stress weight vector is introduced. This vector primarily identifies and quantifies the relative contribution of different environmental stresses to the aging of coatings in specific regions. By collecting long-term, fine-grained meteorological and environmental monitoring data of the target region, key factors significantly affecting coating weather resistance and their temporal characteristics (e.g., diurnal variation, UV radiation, pollutants, and seasonal cycles) are extracted from the data. Specifically, multiple accelerated aging tests are designed, each intensifying a specific regional stress factor. The coating performance degradation rate is compared, and the stress corresponding to the test with the fastest degradation is assigned a higher weight. The regional stress weight vector is then derived through an optimization algorithm. When selecting or developing coatings for specific regions, a high weather resistance index specific to that region must be used. The expression is:

[0044] In the formula, It is for single stress The rating (such as ultraviolet light, salt spray) is for a specific single environmental stress. After accelerated aging tests (such as "salt spray"), a standardized score for a single stress factor is calculated. Let be the regional stress weight vector, and have .

[0045] In an optional implementation, the gray relational analysis method can also be used to deduce the regional stress weight vector through optimization algorithms in step S200. A correlation matrix is ​​established between the historical meteorological database of the target region and multiple sets of single-stress accelerated aging test data. The gray relational degree between each stress factor (such as annual average ultraviolet radiation and annual average salt deposition) and the coating performance degradation rate is calculated. After normalizing the correlation degree, it is directly used as the stress weight vector for that region.

[0046] In another optional implementation, the regional stress weight vector derived from the optimization algorithm in step S200 can also be obtained using principal component analysis. For example, long-term multi-dimensional environmental monitoring data of the target region can be obtained to construct an environmental stress matrix. The matrix is ​​standardized and the correlation coefficient matrix is ​​calculated, and then the eigenvalues ​​and eigenvectors are solved. Principal components with a cumulative variance contribution rate exceeding 85% are extracted, and the absolute values ​​of the loading coefficients of each environmental factor in the principal components are normalized to obtain the objective stress weight vector of the region. This method can eliminate the coupling interference between environmental factors and objectively reflect the dominant aging factors of the region.

[0047] In this embodiment of the application, step S300 constructs a long-term durability performance evaluation sub-model based on the full-cycle data of accelerated aging tests to obtain a long-term durability performance index, including: Specifically, the same method of obtaining the anti-aging combination weight is used to determine the long-lasting combination weight.

[0048] Furthermore, construct a long-lasting performance index. The expression is:

[0049] In the formula, For long-term and sustainable weighting; It is a standardized score for long-lasting effects obtained through accelerated aging tests.

[0050] It should be noted that, It is a relatively static index, not calculated from the measurement value at a specific point in time. Instead, it comprehensively analyzes all performance degradation data throughout the entire test cycle (from the beginning to the end of the test), extracts the key features that can characterize the "long-lasting" properties of the coating, and quantifies these features into a comprehensive score.

[0051] In this embodiment of the application, step S400 involves weighted integration of the anti-aging performance index, high weather resistance performance index, and long-lasting durability performance index to construct a comprehensive performance index model, resulting in a comprehensive performance index, including: Specifically, to achieve a comprehensive evaluation of anti-aging, high weather resistance, and long-lasting durability, the evaluation results of the three dimensions—anti-aging performance index, high weather resistance performance index, and long-lasting durability performance index—are integrated. Considering the dynamic contribution of these three sub-performance indices throughout the coating's lifespan, a time-dependent, dynamically integrated comprehensive performance index model is defined, with the following expression:

[0052] In the formula, For comprehensive performance index, , These respectively reflect the coating's anti-aging, high weather resistance, and timely performance status at time t; since long-term durability is a pre-assessment of the coating's overall lifespan potential, therefore It is considered a constant that does not change with time. , , It is an aggregate weight, and Weight This demonstrates the ability to respond promptly to complex environments; weighting Reflects the intrinsic stability of the material; weight This demonstrates the coating's long-term potential to withstand harsh climates.

[0053] Among them, weight , , The weighting interval distribution is mainly determined based on the severity of the coating application environment and the focus of performance requirements, as shown in Table 2: Table 2

[0054] In this embodiment of the application, step S500 involves constructing a graded evaluation ladder function based on the comprehensive performance index to obtain the comprehensive performance graded evaluation results of the coating and the corresponding optimization decision instructions, including: Specifically, through the comprehensive performance index The quantitative results of the comprehensive performance index were obtained. .

[0055] Construct a hierarchical evaluation ladder function, the expression of which is:

[0056] In the formula, The evaluation result is N1 and N2, which are the comprehensive performance critical values ​​that distinguish the evaluation level. N1 is determined based on the minimum performance baseline of the standard specification, and N2 is determined based on the performance benchmark of the industry benchmark.

[0057] when At that time, the evaluation result was (Low), generates material selection adjustment instructions: It is necessary to readjust the material selection, processing and preparation process, coating process, etc. of the anti-pollution flashover coating of the insulator; when At that time, the evaluation result was (in Chinese), generate process optimization instructions: optimize and improve the processing and preparation process and coating process of the anti-flashover coating; when At that time, the evaluation result was (High), Generate selection application instructions: Directly used as selection for the treatment of pollution flashover prevention of transmission line insulators.

[0058] In an optional implementation, the evaluation results obtained in step S500 using graded evaluation can also employ fuzzy membership functions. For example, instead of setting single hard thresholds N1 and N2, trapezoidal or triangular membership functions corresponding to the three levels of "low, medium, and high" can be constructed. The calculated comprehensive performance index CPI is substituted into each membership function to calculate its membership degree to each level, and the final level is determined based on the principle of maximum membership degree.

[0059] In another optional implementation, the evaluation results obtained in step S500 using hierarchical evaluation can also be obtained using an adaptive partitioning method based on K-Means clustering. A dataset is constructed by collecting the comprehensive performance index (CPI) of the coating to be evaluated and historical coating samples. The K-Means clustering algorithm is used to map the dataset to a one-dimensional space and cluster it into K clusters (K=3, corresponding to poor, medium, and excellent, respectively). The arithmetic mean of the adjacent cluster centers is taken as the dynamic evaluation thresholds N1 and N2.

[0060] Example 3 is an embodiment of the present invention. Based on the above embodiments, an experiment is provided to comprehensively evaluate the anti-aging, high weather resistance and long-lasting durability of the superhydrophobic anti-flashover coating, so as to verify its feasibility and effectiveness. ① The standardized score of the coating's anti-aging performance was obtained based on the statistics of accelerated aging tests. This indicates that the performance retention rate relative to the initial state is 80%; simultaneously, an objective weight for anti-aging is obtained.

[0061] The subjective weights of anti-aging by experts were obtained using the AHP method. The weights given by the three experts were: Expert A: (0.5, 0.3, 0.2); Expert B: (0.4, 0.35, 0.25); Expert C: (0.45, 0.3, 0.25). The average value was (0.45, 0.317, 0.233), which was approximately (45, 32, 23). After adjustment, it was simplified to (40, 30, 20) and used as the subjective weight of anti-aging.

[0062] Anti-aging combination weights:

[0063] Anti-aging performance index:

[0064] ② The standardized score for high weather resistance of the coating was obtained based on the statistics of accelerated aging tests. Similarly, determine the weighting of high weather resistance combinations:

[0065] High weather resistance index:

[0066] ③ Considering overall performance as the most important factor, followed by degradation stability, and then predicting lifetime, the combined weight of long-lasting and durable performance is set as follows: Where 15 represents the relative importance of the predicted lifespan indicator; 35 represents the relative importance of the decay stability indicator; and 40 represents the relative importance of the overall performance retention indicator.

[0067] The standardized score for high weather resistance of the coating was obtained based on accelerated aging test statistics. This means that the coating's average score across all indicators in the long-lasting accelerated aging test is approximately 80 points.

[0068] Long-lasting performance index:

[0069] ④ Setting The comprehensive performance index model is constructed as follows:

[0070] ⑤ Set the critical value of the comprehensive performance index used to distinguish the evaluation and classification. , The hierarchical evaluation ladder function is constructed as follows:

[0071] because =6237, therefore, the comprehensive performance evaluation result of the anti-pollution flashover coating of transmission line insulators is medium, which means that it needs to be given further attention. Further optimization and improvement of the processing and preparation process and coating process of the anti-pollution flashover coating can be used to improve the anti-pollution flashover effect of the coating, and continuous tracking and evaluation should be carried out.

[0072] In summary, by integrating the physicochemical properties, mechanical stability, anti-flashover effectiveness, and aging degradation laws of anti-flashover coatings through accelerated aging tests, and combining the analytic hierarchy process (AHP) with regional environmental characteristics, sub-models for evaluating the anti-aging performance, high weather resistance, and long-term durability of anti-flashover coatings were established. These sub-models incorporate the coating's anti-aging performance, high weather resistance, and long-term durability into a comprehensive evaluation system with multiple indicators, multiple weights, quantifiability, and predictability, providing a scientific basis for coating research and development, performance evaluation, and service life prediction.

[0073] Example 4 illustrates a schematic scheme for a comprehensive evaluation method of the anti-aging, high weather resistance, and long-lasting durability of a superhydrophobic anti-flashover coating. It should be noted that the technical solution of this system for comprehensively evaluating the anti-aging, high weather resistance, and long-lasting durability of a superhydrophobic anti-flashover coating belongs to the same concept as the technical solution of the aforementioned comprehensive evaluation method for superhydrophobic anti-flashover coatings. Details not described in detail in the technical solution of the system for comprehensively evaluating the anti-aging, high weather resistance, and long-lasting durability of a superhydrophobic anti-flashover coating in this embodiment can be found in the description of the technical solution of the aforementioned comprehensive evaluation method for superhydrophobic anti-flashover coatings.

[0074] This embodiment also provides a comprehensive evaluation system for the anti-aging, high weather resistance, and long-lasting durability of superhydrophobic anti-flashover coatings, including: The anti-aging module is used to conduct accelerated aging tests on the coating, and combined with the analytic hierarchy process (AHP), constructs a sub-model for evaluating anti-aging performance to obtain the anti-aging performance index. The high weather resistance module is used to construct a high weather resistance performance evaluation sub-model by combining accelerated aging tests with regional environmental characteristics, and obtain the high weather resistance performance index. The long-lasting and durable module is used to construct a long-lasting and durable performance evaluation sub-model based on full-cycle data from accelerated aging tests, and obtain the long-lasting and durable performance index.
