The invention provides an anti-fouling floating body and a preparation method thereof. The anti-fouling floating body comprises a floating body and an anti-fouling film arranged on the side, making contact with the water surface, of the floating body. The antifouling film comprises a surface layer film and a binder layer arranged between the surface layer film and the antifouling floating body; the surface energy of the surface layer film is lower than 25mJ/m < 2 >; and the binder layer comprises a binder and an antifouling auxiliary agent. The anti-fouling membrane is arranged on the floating body and comprises the surface layer membrane with low surface energy and the binder layer containing the anti-fouling additive, on one hand, the surface layer membrane with low surface energy can prevent fouling organisms in a water body from being attached, and on the other hand, the anti-fouling additive in the binder layer can kill a small amount of fouling organisms attached to the surface of the membrane, so that the anti-fouling effect of the floating body is improved, and the service life of the floating body is prolonged. Therefore, the buoyancy of the floating body borne by the water surface is not damaged.

    本发明提供了一种防污浮体及其制备方法,包括浮体本体和设置在所述浮体本体与水面接触一侧的防污膜;所述防污膜包括表层膜和设置在所述表层膜和防污浮体之间的粘结剂层;所述表层膜的表面能低于25mJ/m2;所述粘结剂层包括粘结剂和防污助剂。本发明在浮体本体上设置防污膜,所述防污膜包括表面能低的表层膜和含有防污助剂的粘结剂层,一方面,表面能低的表层膜能够防止水体中污损生物附着,另一方面,粘结剂层中的防污助剂能够对少量附着在膜表面的污损生物进行消杀,使其自行脱落,使得水面承载浮体浮力不受损。
