Air cap to the sealed with resin coating buoy the green form

摘要

The present invention relates to a buoyant material used in a buoy for fish farms, a buoyant bucket for work barges, and a buoy for fishing gears. Most buoyant materials are made of foamed Styrofoam and cause small grains to float around when damaged by waves, winds, or fishes and shellfishes such as barnacles, that cannot be easily recovered, which is the root cause of a great pollution of the marine environment. Thus, it is being attempted to remove Styrofoam from the ocean all over the world. In recent years, as an alternative, a synthetic resin is coated on foamed Styrofoam or a buoyant bucket is manufactured by plastic injection, but a synthetic resin coating agent is damaged or the plastic injection is broken when used, and thus are unable to serve as an alternative. Accordingly, the present invention is configured to manufacture an environment-friendly buoy which can be used as a buoy for fish farms and a buoyant bucket for work barges by rolling an air cap, being used as a packaging material and a heat insulating material, into a plastic branch pipe to make a cylindrical column, and coating the same with a synthetic resin to seal the same (pure urea and modified polyurea super-G, PP, PE, and thermoplastic materials, and the like).
