Abstract

The invention discloses an antifouling and anticorrosive marine coating which is prepared from polymerized o-toluidine, polytrifluorochloroethylene, aldehyde ketone resin, alkyl succinimide, eucalyptus oil, toosendanin, dicyclopentenyl oxyethyl acrylate, hydroxypropyl methyl cellulose, coumarone indene resin and water-based chlorinated rubber, and the mixture is prepared according to the mass ratio of 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. The marine coating is excellent in performance, the effective component obtaining mode is simple, convenient and rapid, a shipbody can be effectively protected against seawater erosion influences, and marine neoplasm attachment is effectively prevented.

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, autonomous regions 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-fouling have always been the primary issue that marine industries such as marine fishery, marine transportation, ...
