| Abstract: |
| Objective To evaluate the aging degree of protective coating comprehensively from mechanical property and appearance rating. Methods Nine coating degradation indexes of loss of gloss, color change, pulverization, foaming, mildew, rust, peeling, cracking, adhesion were selected to calculate and analyze the weight with the entropy value method. Results The comprehensive evaluation values of two kinds of protective coatings of TB06-9 + TS70-60 and TB06-9 + TS96-71 after marine atmospheric outdoor environment exposure for 5 years by the entropy method were 3.88. The anti-aging performance of the two protective coatings was almost the same. Conclusion The coating degradation index weight of loss of gloss, color change, pulverization, foaming, mildew, rust, peeling, cracking, adhesion was effectively identified by the entropy method, which provides an objective, real, effective and scientific evaluation method for multi index comprehensive evaluation of protective coating aging. |
