Abstract
Description
Technical Field
[0001] This application relates to the field of automotive coating technology, and in particular to test methods, electronic equipment, storage media, and test platforms for the influence of skid-mounted anti-stick coatings on pretreatment electrophoresis bath solutions. Background Technology
[0002] In the electrophoresis pretreatment stage before coating, electrophoretic paint residue easily adheres to the surface of the skid. If not removed in time, it will adversely affect production efficiency and product quality. Currently, traditional methods for removing paint residue from skids mainly fall into four categories:
[0003] (1) Physical methods such as rinsing with a high-pressure water gun and mechanical grinding / scraping;
[0004] (2) Chemical dissolution method using paint remover;
[0005] (3) Thermal decomposition using a high-temperature incinerator;
[0006] (4) A combination of coating the skid surface with an anti-stick coating and then cleaning with a high-pressure water gun.
[0007] However, the above four methods have obvious limitations: physical methods are not thorough in cleaning paint residue from edges and corners, and generate hazardous waste with high treatment costs; chemical dissolution methods not only consume large amounts of chemical reagents, but also produce wastewater that is difficult to treat; and high-temperature incinerator methods have problems with high equipment investment and high energy consumption. Therefore, the combination of coating the skid surface with an anti-stick coating and cleaning with a high-pressure water gun is gradually becoming a development trend.
[0008] However, the current market offers a wide variety of skid-mounted anti-stick coatings. Under prolonged exposure to the strong chemical erosion of pretreatment processes (degreasing, phosphating) and the mechanical and electrochemical conditions of the electrophoresis bath, these anti-stick coatings may age, powder, and peel off. The detached coating fragments can contaminate the pretreatment tank and electrophoresis bath, leading to a series of quality problems, such as: pinholes, particles, and impurities in the electrophoretic coating film; affecting the stability parameters of the bath (such as conductivity, pH value, solvent content, etc.); and impacting the corrosion resistance of the coating film. Currently, the industry lacks a standardized and efficient laboratory method to pre-assess the chemical resistance of different anti-stick coatings and their potential impact on the bath. Typically, analysis and treatment can only be carried out post-incidentally, resulting in significant production downtime losses and quality risks.
[0009] Therefore, there is an urgent need for a test method to investigate the impact of skid-mounted anti-stick coatings on the pretreatment electrophoresis bath solution. This method should be able to simulate on-site working conditions in the laboratory and provide a rapid, accurate, and comprehensive evaluation of the performance of the anti-stick coating and its impact on the bath solution.

It fills the gap in the industry for the lack of pre-emptive and standardized evaluation methods for anti-stick coatings, realizes the technological transformation from "post-processing" to "pre-judgment", and constructs a standardized laboratory evaluation system.

[0135] In one specific embodiment, a test method is disclosed for the effect of a skid-mounted anti-stick coating on the pretreatment electrophoresis bath solution, such as... Figure 3 As shown:
[0136] The experimental conditions simulating the production site environment include: method for determining the size of the skid anti-stick coating test piece, preparation of the skid anti-stick coating test piece, experimental equipment, tank solution preparation, and tank solution parameter setting.
[0137] The method for determining the size of the skid-mounted anti-stick coating test piece includes: calculation basis, parameter definition, calculation formula, and size determination.
[0138] Calculation basis: Based on the actual volume of the production line tank, the maximum allowable workpiece area, and the amount of tank liquid that the experimental equipment can hold, the area of the anti-stick coating test piece for the test skid is determined by proportional conversion.
[0139] Parameter definitions: V0 - Volume of the production line tank (unit: m³ or L), S0 - Maximum area of the skids entering the tank simultaneously (unit: m² or cm²), V1 - Allowable tank liquid volume for the experimental equipment (unit: m³ or L, must be consistent with V0 unit), S1 - Theoretical calculated area of the anti-stick coating test piece for the skids used in the test (unit: m² or cm², must be consistent with S0 unit).
[0140] Area calculation formula: S1=S0×(V1 / V0).
[0141] Size determination: Under the premise of satisfying the calculated area S1 above, and combined with the effective placement space (length and width) of the experimental equipment, the specific length and width dimensions of the skid anti-stick coating test piece are finally determined.
[0142] In the preparation of skid-mounted anti-stick coating test pieces, the anti-stick coating material to be tested is prepared into test pieces of a certain size and cured in accordance with the actual construction process.
[0143] The testing equipment includes: test barrels, analytical balances, measuring cups, stirrers, constant temperature water tanks, pH meters, conductivity meters, drying ovens, acid-base burettes, salt spray test chambers, aging test chambers, damp heat test chambers, cupping test equipment, stone impact resistance equipment, cross-cut testers, film thickness gauges, electron scanning microscopes, and infrared spectrometers.
[0144] In the preparation of the bath solutions, the degreasing bath solution, surface conditioning bath solution, phosphating bath solution, and electrophoresis bath solution are all prepared using the same method as for preparing new bath solutions.
[0145] When setting parameters, all parameters are set in conjunction with the production line.
[0146] The test method for the effect of skid-mounted anti-stick coating on the pretreatment electrophoresis bath solution includes the definition of the immersion time of the anti-stick coating specimen in the bath solution and the test procedure.
[0147] The immersion time of the anti-stick coating test piece in the bath solution is defined as the entire time interval from when the test piece is fully immersed in the bath solution to when the bath solution is removed. In this embodiment, the immersion time is defined as 7 days.
[0148] During the experiment, testing equipment was used to detect the parameters and infrared spectral elements of the newly prepared degreasing bath, surface conditioning bath, phosphating bath, and electrophoresis bath to ensure that they met the median threshold values specified for production. Phosphating test piece CP-P0 and electrophoresis test piece CP-ED0 were prepared. The test piece size must meet the allowable size of the performance testing equipment; a length of 150 mm and a width of 70 mm is recommended.
[0149] like Figure 4 As shown, the anti-stick coating test pieces were immersed in the above bath solutions, and the anti-stick coating test pieces were observed daily for bubbling. When the bubbling level reached level 4 (according to standard ISO4628, a rating rule was pre-set, and multiple bubbling levels were pre-set before evaluation), the test pieces were evaluated. Figure 4 (For actual samples, the bubbling level reaches level 4). Record whether the coating has peeled off every 4 hours. Stop recording when the peeling area reaches 20% or until the soaking time of 7 days is reached.
[0150] Parameters and infrared spectral elements of the degreasing bath, surface conditioning bath, phosphating bath, and electrophoresis bath were tested after immersing the anti-stick coating test pieces. Phosphating test piece CP-P1 and electrophoresis test piece CP-ED1 were prepared. The test piece size must meet the allowable size of the performance testing equipment; a length of 150 mm and a width of 70 mm is recommended.
[0151] The evaluation methods for the impact of skid-type anti-stick coatings on the pretreatment electrophoresis bath solution include bath solution evaluation methods and performance evaluation methods.
[0152] In the bath evaluation method, the parameters and elements of the newly configured bath solution and the parameters and elements of the bath solution after soaking the anti-stick coating test piece are analyzed to determine the influence of the skid anti-stick coating on the bath solution.
[0153] In the performance evaluation method, the phosphating film parameters of phosphating test pieces CP-P0 and CP-P1 are tested, including appearance, film weight, crystallinity, and phosphorus ratio. Result determination: If both CP-P0 and CP-P1 are qualified, the skid-mounted anti-stick coating is deemed to have no effect on the pretreatment; if CP-P0 is qualified but CP-P1 is unqualified, the skid-mounted anti-stick coating is deemed to have failed during the pretreatment process, and the affected bath solution is further analyzed based on the bath evaluation results, at which point the test is terminated; if CP-P0 is unqualified, the newly prepared bath solution is deemed unqualified, and the test must be repeated.
[0154] The film thickness, adhesion, stone chip resistance, damp heat resistance, salt spray resistance, and aging resistance of electrophoresis test pieces CP-ED0 and CP-ED1 were tested, and the quality status of the two test pieces was compared. Results were determined as follows: If both electrophoresis test pieces CP-ED0 and CP-ED1 were qualified, the skid-mounted anti-stick coating was deemed to have no effect on electrophoresis; if CP-ED0 was qualified but CP-ED1 was unqualified, the skid-mounted anti-stick coating was deemed to have an impact on electrophoresis, and further analysis of the influencing factors was needed based on the bath evaluation results; if CP-ED0 was unqualified, the newly prepared bath solution was deemed unqualified, and the test needed to be repeated.
[0155] In this embodiment, the test method for the effect of the skid anti-stick coating on the pretreatment electrophoresis tank solution is combined with the status of the production line and the accelerated simulation test process in the laboratory environment, including how to combine production and how to conduct the test.
[0156] In this embodiment, a comprehensive evaluation system for the impact of the skid-mounted anti-stick coating on the pretreatment electrophoresis bath solution is implemented, simultaneously considering bath parameters, changes in bath composition, coating failure, and the final paint film quality.
