Abstract

The invention discloses a fluorocarbon coating as well as a preparation method and application thereof, and belongs to the technical field of coating preparation. The fluorocarbon coating is prepared by mixing a component A and a component B according to a mass ratio of 10:(0.8-1). The component A is prepared from 60 to 65 parts of fluorocarbon resin, 5 to 10 parts of modified whisker zinc oxide, 5 to 10 parts of modified silicon dioxide, 0.3 to 0.5 part of zinc molybdate, 4 to 8 parts of zinc borate, 0.3 to 0.5 part of zinc sulfate, 0.5 to 1.8 parts of dispersing agent, 0.2 to 0.5 part of flatting agent, 0.1 to 0.3 part of defoaming agent and 12 to 14 parts of solvent. The invention further discloses a preparation method of the fluorocarbon coating. The fluorocarbon coating is obtained by mixing the component A and the component B. The invention also provides an application of the fluorocarbon coating in preparation of a marine ship surface coating. The fluorocarbon coating belongs to a high-solid environment-friendly coating, and the corrosion resistance of the fluorocarbon coating is improved while the mechanical property of the fluorocarbon coating is ensured.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a fluorocarbon paint and its preparation method and application. Background technique [0002] The part below the waterline of the ship has been immersed in seawater for a long time, and is not only corroded by seawater itself, but also by various marine organisms adhering to the surface of the material. The hulls that are not immersed in seawater, the wet interior cabins, open decks and other areas are also in the marine atmospheric corrosion environment for a long time. Therefore, the metal components of the ship will gradually fail due to long-term seawater corrosion, marine atmospheric corrosion and microbial corrosion. Corrosion in the marine environment has a great negative impact on marine economic benefits and maritime military safety. [0003] Most of the bactericidal and anticorrosion coatings reported for the marine environment are conventional solvent-base...
