Embodiment Construction
[0043] Below in conjunction with accompanying drawing this patent is further explained and illustrated. But the scope of protection of this patent is not limited to the specific implementation.
[0044]In the present invention, two kinds of antifouling coatings with known design life and actual ship service life are selected, combined with antifouling coating antifouling agent exudation rate, antifouling coating abrasion rate (release layer) and coating actual application process The service life of the two antifouling coatings was calculated based on the technical parameters such as the sailing ratio and other technical parameters, and the service life evaluation method proposed in the above research was evaluated by combining the results of the actual sea siding, the dynamic simulation test, and the actual ship use of the two antifouling coatings. The verification was carried out, and the verification results are shown in Table 1.

Abstract
The invention discloses a quick evaluation method for an antifouling service life of a self-polishing antifouling paint. The method comprises the following steps of: measuring the average mouth abrasion velocity Em at a cruising speed; performing conversion from the average mouth abrasion velocity Em into average year abrasion velocity according to cruising stop ratio and cruising period of ships; and calculating the antifouling service life of the antifouling paint by using a model formula. The evaluation method is mainly applied to antifouling performance evaluation of the self-polishing antifouling paint, and has the main advantage that the antifouling performance of long-acting self-polishing antifouling paint can be predicted and evaluated in a short time, so that the quick evaluation method provides a scientific evidence for researching and selecting the antifouling paint; and therefore, research and actual popularization application periods of the antifouling paint are shortened.
Description
technical field [0001] The invention relates to a paint technology, in particular to a rapid evaluation method for the antifouling life of a self-polishing antifouling paint. Background technique [0002] The most accurate evaluation method for the service life of antifouling paints is the real ship test, but the long period of the real ship test is not conducive to the research and development of long-lasting antifouling paints. Foreign countries have carried out laboratory evaluation technology research work very early. The United States began the hanging panel test of antifouling coatings in the early 19th century. In the 1870s, the United States established the shallow sea hanging panel test method and dynamic simulation test of antifouling coatings. Established the test method of abrasion rate and the test method of copper ion and organotin exudation rate; around 2000, with the application of new environment-friendly antifouling agents, the test method of exudation rate...
