Embodiment Construction
[0018] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0019] In view of the fact that there is no method for detecting the matching effect of water-based paint and sealant in the prior art, the present invention provides a method for detecting cracking under the matching of water-based paint and sealant for automobiles, which can detect and analyze the matching use of water-based paint and sealant for automobiles. Evaluation, testing the cracking of different types of water-based paints and sealants for on-site use, evaluating the test results, quickly determining whether the water-based paint and sealants are well matched, and providing a reliable basis and reference for subsequent production.
[0020] The automobile water-based paint provided by the embodiment of the present invention is matched with the sealant and the cracking detection metho...

The invention discloses a cracking detection method under the cooperation of automobile water paint and sealant. The cracking method mainly comprises the following steps: coating a test board with a coating, blending oil paint, spraying the oil paint on the coating, controlling the test board to carry out a cracking simulation test, and detecting and analyzing the result of the cracking simulationtest. According to the cracking detection method under the cooperation of automobile water paint and sealant, the cracking conditions of different types of water paint and field sealant can be quickly detected, the detection result is evaluated, whether the matching performance of the water paint and the corresponding sealant is good or not is quickly determined, and the cracking detection and evaluation method under the cooperation of water paint and sealant is easy to operate, good in controllability and high in repeatability, and can realize quick detection and judgment, so that referencebasis is provided for field cooperative application of water paint and sealant.
Description
technical field [0001] The invention relates to the technical field of crack detection of automotive paint, in particular to a crack detection method for automotive water-based paint and sealant. Background technique [0002] With the strict requirements on the automobile industry in terms of environmental protection in China, the application of water-based paint as an environmentally friendly, high-quality and low-cost paint in the automobile coating process continues to expand. At present, domestic automobile OEMs have invested a lot in the application and research of water-based paint technology. [0003] In the process of automobile production, water-based paint inevitably needs to be used in conjunction with other auxiliary materials for automobile painting, and the application of water-based paint with automotive sealants is particularly important. In production, sealant and water-based paint often have the problem of cracking after drying in the matching application,...
