Description
Technical field
The present invention relates to a kind of self-polishing antifouling paint and preparation method thereof, be especially suitable for hull-bottom antifouling.
Background technology
Attachment of the marine growth to hull bottom increases the roughness of hull bottom outer surface, adds ship resistance, reduce with being stained
The speed of a ship or plane, adds fuel consumption.In addition, attachment of the marine growth to shell also accelerates the corrosion of hull with being stained, shorten
The service life of ship, damages to navigation safety.According to incomplete estimation, the whole world is every year by marine biofouling is made
Into economic loss more than 1,000,000,000 dollars.It is therefore prevented that the attachment of marine organisms is with being stained always naval's national defense construction, sea
Communications and transportation and the vital task of ocean engineering exploitation.In order to control marine growth to be stained ship and ocean engineering facility,
Develop that electrolysis antifouling, low-surface-energy are antifouling, ultrasonic wave is antifouling, water under high pressure is washed away, the multiple technologies such as application of anti-fouling paint.
But it is still to prevent sea on naval vessel and ocean engineering facility external coating antifouling paint no matter in terms of economy or application effect
Most economical, the effective and practical technology of biodeterioration.
China carried out system research since 1966 to ship bottom anti-fouling paint.Successively develop asphalt series, ethene system, propylene
Acid system, chlorinated rubber system antifouling paint, the triennial effect anti-fouling paint of 72-19 long-acting antifouling paints, 71-33 used such as present ship,
839 acrylic acid anti-fouling paints etc., it is still the main anti-fouling paint kind of domestic paint production factory so far.According to antifouling mechanism, these
Anti-fouling paint can be attributed to controllable lysotype.The anti-fouling agents such as this kind of product mercury containing DDT//organotin of early stage, good antifouling effect.It is existing
The anti-fouling agent of this kind of disabling has been substituted in formula, but this more or less reduces the antifouling capacity of coating.
Late 1970s, develop acrylic acid tin polymer self-polishing coating, effect of the coating in alkaline seawater
Under, polymer constantly hydrolyzes, and slowly releases organotin groups and plays antifouling effect.Organotin is stanniferous in polymer from polishing
Monomer component content is serious to marine pollution up to 30%~50%.International Maritime Organization (IMO) requires that in January, 2003 prohibits comprehensively
The only use of the anti-fouling paint containing TBT (tributyl tin), in January, 2008, hull surface no longer applies any anti-fouling paint containing TBT.
At present, the main product in anti-fouling paint market is tin-free self-polishing paint.Machine according to acrylic acid tin polymer from polishing
Reason, develop using acrylic acid copper, zinc acrylate resin and alkyl acrylate radical siloxane from resin is polished as base-material, using cuprous oxide to kill
The antifouling paint of raw agent.With acrylic acid cu zn/silane ester polymer and cuprous oxide prepare self-polishing coating can control copper from
Sub effectively release, has good polishing performance, but solids content is relatively low.CN 101550305A long-life self-polishing antifouling coatings, it is open
A kind of long-life self-polishing antifouling coating, is made up of acrylate resin, composite anti-fouling agent, color stuffing, anti-settling agent, solvent etc., fits
Used for hull bottom position as anti-fouling paint, effectively marine growth can be prevented to be stained hull bottom in 3~5 years.Belonged to together with above-mentioned
The products of Intersmooth 365 of a kind of international paint companies are to polish resin, cuprous oxide, zineb certainly by acrylic acid copper
Prepare, its volume solid is divided into 40%, VOC (VOC) content height, and not adapted to current environmental protection will
Ask.
