Abstract

The invention belongs to the technical field of anticorrosive paint, and particularly relates to anticorrosive paint applied to ships and a preparation method of the anticorrosive paint. The anticorrosive paint applied to the ships is prepared from the following raw materials in parts by weight: 40-60 parts of epoxy resin, 5-15 parts of a modified basalt flake/carbon nitride composite material, 3-8 parts of a samarium and copper co-doped zinc oxide/graphene composite material, 10-18 parts of filler, 1.5-6 parts of an auxiliary agent and 20-30 parts of water. The anticorrosive paint applied to the ship can solve the practical problem that the ship needs bacteriostasis and corrosion prevention, has excellent adhesive force and good wear resistance, can bear high and low temperature and high salinity, can well resist bacterial corrosion, and achieves bacteriostasis and corrosion prevention effects.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion coatings. More specifically, it relates to an anti-corrosion coating applied to ships and a preparation method thereof. Background technique [0002] With the rapid development of marine shipping and the continuous development and utilization of marine resources, the harm caused by marine biofouling has become increasingly prominent. For ships navigating in the ocean, if the marine fouling organisms are not effectively prevented and controlled, they will adhere to the surface of the hull, increase the weight of the hull and the surface roughness of the hull, increase the navigation resistance, and reduce the speed and maneuverability of the ship. Marine biofouling is a key research direction for human ocean activities, and antifouling coatings are currently the most convenient, cost-effective prevention and control method. [0003] Graphene has been widely studied in many fields due to its...
