Description
Technical field
The invention belongs to marine paint technical field, be specifically related to a kind of Wuxi, without the environment-friendly type marine antifouling coating of copper and preparation
Method and painting method.
Background technology
Boats and ships navigate by water for a long time, stop still in port or in anchorage particularly for a long time, and hull surface underwater is immersed in the water
Part, especially hull bottom surface can get rusty due to long period of soaking in water, and grow the plants such as Sargassum, barnacle, pipe worm,
The animals such as shellfish, floating material and abiotic class, such as the mixture etc. of Organic substance Yu inorganic matter remains.And constantly cause under water
Dirty and the coarse phenomenon of hull and hull bottom surface of part is referred to as the dirt end, is commonly called as " becoming mildewed ".(the raw attachment in sea) at the bottom of boats and ships dirt
Produce is very harmful, and the existence at the dirty end is the key factor affecting ship's navigation, and it not only increases ship's navigation
Resistance, and add the weight of ship self.Due to the increase of ship resistance, on the one hand cause under the speed of a ship or plane speed of boats and ships
Fall, affects the rapidity of ship, on the other hand, owing to resistance increases, causes propeller working order to change, cause propeller to push away
Enter efficiency to decline, cause the speed of a ship or plane to slow down accordingly.It is generally acknowledged in numerous navigation practical experiences and newly launch a ship latter six months, because of dirt
The end and the resistance that increases can reach more than the 10% of drag overall.Main frame fuel consumption increases (may make a typical pleasure boat increase
Adding 50%, general ship increases 20%-30%) and the problem such as ship speed reduction.It is known that marine fuel oil consumption costs
In vessel operating cost, account for even can be described as quite greatly the ratio of maximum.The increase of fuel consumption, not only increases ship
The operation costs of oceangoing ship, add the burden of shipping enterprise, and owing to the impact of ship speed reduction can extend all turn-weeks of boats and ships
Phase, reduce the operation efficiency of boats and ships, reduce the investment return of shipping company.
The problem at the bottom of boats and ships dirt that how to solve is the key subjects that whole world shipping world faces, and the research and development of its antifouling paint are passed by
The poisonous developmental stage to low toxicity.Representational product is the self-polishing antifouling paint SPA containing organo-tin compound (TBT).By
There is hypertoxicity in TBT (organotin), have a strong impact on marine growth, pollution of marine environment.Therefore International Maritime Organization (IMO)
" calendar year 2001 world control boats and ships are harmful to system pact of the antifouling end " (lotus claims AFS pact) disabling TBT has been formulated in 2008.
The anti-fouling paint that the whole world commonly uses now is tin-free self-polishing paint, and this paint system low toxicity coating, main component is Red copper oxide.Its profit
By the shear action of hull Yu sea water, constantly release Red copper oxide reaches anti-fouling effect.The coating reduces toxicity, but antifouling
Less effective, and Red copper oxide system heavy metal, cause certain pollution and biomutation to ocean and marine growth.It is reported,
San Diego, USA marine site has disabled Red copper oxide.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of Wuxi, without the environment-friendly type marine antifouling coating of copper and system
