A kind of antifouling and anticorrosion marine coating

Abstract

The invention discloses an antifouling and anticorrosion marine coating, which is composed of polymerized o-p-methylaniline, polychlorotrifluoroethylene, aldehyde and ketone resin, alkyl succinic imide, eucalyptus oil, azadirachtin, acrylic acid dicyclopentenyl oxide Ethyl esters, hydroxypropyl methylcellulose, coumarone-indene resins and water-based chlorinated rubbers according to 7-19: 4.6-5.8: 7.7-9.4: 8-11.2: 6-14: 9-16: 6 ‑8: 4‑6: 4‑6: 2.7‑6.1 mass ratio of the mixture made. The marine coating of the invention has excellent performance, and the method of obtaining the active ingredients is simple and fast, which can effectively protect the hull from seawater erosion and effectively prevent the adhesion of marine neoplastic organisms.

Description

【Technical field】 [0001] The invention relates to the technical field of marine coatings, in particular to an antifouling and anticorrosion marine coating. 【Background technique】 [0002] The data shows that the ocean plays a huge role in the economic and social development of my country's eastern coastal areas. The land area of ​​the 12 coastal provinces, districts and municipalities accounts for only 14% of the country's land area, but its GDP accounts for 60% of the country's total. The national marine economic output value was 8 billion yuan in 1980, 43.8 billion yuan in 1990, 413.3 billion yuan in 2000, 1.3 trillion yuan in 2004, and 3.8 trillion yuan in 2010, with a growth rate of more than 20%. The development of the marine economy is inseparable from the support of "boats and ships" and other marine facilities, and marine anti-corrosion and anti-pollution have always been the primary issues that marine industries such as marine fishery, marine transportation, and ma...
