The synthetic antifouling marine coating is prepared from the following raw materials in percentage by weight: 65%-85% of copolymer, 10%-30% of a solvent, 1%-2% of nano SiO2, 1%-2% of nano TiO2, 1%-1.5% of KLE-333, 1%-2% of KF-64 and 0.5%-1% of KSL-52. The synthetic biodegradable antifouling marine coating can be hydrolyzed under the action of seawater and the like; the surface layer automatically falls off; the coating has self-polishing property; and the surface energy of a base material is reduced, so that the base material has dual characteristics of self-polishing property and low surface energy. The nano TiO2 is added to the coating as an antifouling agent; growth of planktons in sea and adhesion of the coating can be inhibited under the photo-catalysis action; and the problems that an existing single antifouling marine coating is poor in use effect and large in dosage, and generates secondary pollution to a marine environment are solved.
Description
Technical field
The present invention relates to a kind of biodegradation type marine antifouling coating and preparation method thereof, belong to coating technology Application Areas.
Technical background
Since the mankind are engaged in Activities of Ocean, the control of marine biofouling is the important topic of research always.Marine biofouling not only produces corrosion to the surface of hull, harbour, marine oil pipeline and marine drilling platform, the surface of hull is made to produce roughness, bring very large friction resistance, hull weight also can be caused to increase, reduce ship's speed, need to consume more fuel, cause the increase of emissions figure.About the control of marime fouling, there is various solution in mankind's history of marine navigation.Wherein effective, the most most popular anti-fouling method is the tributyl tin self polishing copolymer antifouling paint (TBT-SPC) of the seventies research and development in last century, and the boats and ships in the whole world 70 percent use this coating, thus have very huge economic benefit.But TBT-SPC anti-fouling system pollution of marine environment, produces great effect to halobiontic growth and breeding.
What adopt from the skeleton of polishing or hydrolysis-type marine antifouling coating or base-material is the coating that the superpolymer being easy to be hydrolyzed is made, in the skeleton of these superpolymer or by adding some sterilants, stain control agent and disinfectant etc., or some heavy metal ion such as Sn, Zn, Cu are incorporated in molecular skeleton, make superpolymer (such as being polyacrylic ester, poly-aminoresin etc.) and play antifouling effect.Film prepared is thus under the souring of seawater, by carrying out ion-exchange with the ion in seawater, penetrate institute's metal ion, and then good antifouling property can be played, under the souring of seawater, constantly by the film polishing on surface, constantly expose new surface, make surface become smooth, while polishing, the marine fouling organism be attached on surface coatings also can be made to split away off, play antifouling effect.
Low surface energy antifouling coating for seas has low surface energy, and marine organisms are difficult in coating surface attachment, even if attachment is also insecure, easily comes off under the effect of current or other external force.At present, low surface energy anti-fouling paint mainly organic fluorine and organosilicon coating.Organic fluorine and organosilicon each tool relative merits: fluoro-resin critical surfaces can be lower, mechanical property is better, but due to fluoro-resin be rigid polymer, top layer fouling organism comes off and needs higher-energy, and expensive; The price of silicone resin lower than fluorine resin coating, but its antifouling property and mechanical property poor.
