BETAINE IONIC LIQUID-MODIFIED COATING, AND PREPARATION METHOD AND USE THEREOF

摘要

The present invention provides a betaine ionic liquid-modified coating, and a preparation method and use thereof, and belongs to the technical field of marine antifouling coating. The betaine ionic liquid-modified coating provided in the present invention includes the following components, in mass percentage: 20% to 30% of betaine ionic liquid-modified emulsion, 5% to 15% of rosin emulsion, 20% to 30% of antifoulant, 3% to 10% of pigment/filler, 1% to 2% of water-based additive, 0.5% to 1% of film-forming additive, and the balance of water. The betaine ionic liquid-modified coating provided by the present invention has an ultra-low content of volatile organic compounds (VOCs) (less than 20 g/L), and is environmentally friendly. The betaine ionic liquid-modified coating can form into a coating film with prominent mechanical properties, stable self-polishing rate, and excellent water immersion-resistance and antifouling performance.
