摘要：
The present invention relates to a Styrofoam member produced in a way that a Styrofoam base material manufactured in a predetermined shape is coated with a reinforcing coating layer made of synthetic resin. More specifically, the present invention relates to a low-density and environmental-friendly Styrofoam member with a polyurethane coating layer manufactured in a manner that EVA resin and / or PVAc resin, which are water-soluble adhesives, are/is coated on a surface of the Styrofoam base material to firstly produce a primer bonding layer for providing a bonding base to polyurethane resin, and lastly Flexible and tough polyurethane resin is coated on the primer bonding layer. Although petroleum resin can provide an excellent coating function corresponding to the Styrofoam base material, it is impossible to apply petroleum resin containing organic solvent component to the Styrofoam base material with very weak chemical resistance and non-polarity. However, polyurethane resin together with an optimal primer material can be applied to the Styrofoam member. Thus, it is possible to form a thin-walled coating layer in an economically-efficient manner without using expensive dedicated equipment, and flexibility and impact resistance associated with the Styrofoam base material ensure sufficient safety and service life of the product. Particularly, it is possible to manufacture buoys and other Styrofoam members at a low price such that economic burden on fishermen can be reduced, to provide a low density coating layer which does not deteriorate self-buoyancy of the buoy, and to recycle the Styrofoam member as the coating layer is crushed together with the Styrofoam base material without separately removing the coating layer.COPYRIGHT KIPO 2016본 발명은 소정의 형상으로 제작된 스티로폼 모재의 표면에 합성수지 재질의 보강용 피복층을 코팅시킨 스티로폼 부재에 관한 것으로서, 더욱 상세하게는 스티로폼 모재의 표면에 수용성 접착제인 EVA 수지 및/또는 PVAc 수지를 코팅하여 폴리우레탄 수지의 접착베이스를 제공하는 프라이머 접착층을 1차적으로 조성한 다음, 상기 프라이머 접착층의 표면에 유연하면서도 질긴 성질의 폴리우레탄 수지를 최종적으로 코팅시킴에 따라, 스
