The invention provides a rotational molding boat, and belongs to the technical field of ships. The problem that a foaming material and a shell of an existing rotational molding boat cannot be tightly combined is solved. The rotational molding boat comprises a boat body, and the boat body sequentially comprises a foaming inner core, a blocking inner layer, a foaming outer layer and a shell from inside to outside; or the ship body sequentially comprises a foaming inner core, a foaming outer layer and a shell from inside to outside. According to the rotational molding boat, the foaming inner core and the shell are tightly combined through the foaming outer layer or the foaming outer layer and the blocking inner layer, when the boat body is accidentally impacted, the impact force can be transmitted to the periphery, acting force can be dispersed, energy can be rapidly absorbed, the damage possibility of the shell is reduced, and the impact resistance of the boat body is remarkably improved.
本发明提供了一种滚塑船艇,属于船舶技术领域。它解决了现有的滚塑船艇的发泡材料与外壳无法紧密结合的问题。本滚塑船艇,包括船体,船体由内至外依次为发泡内芯、阻隔内层、发泡外层和外壳;或船体由内至外依次为发泡内芯、发泡外层和外壳。本滚塑船艇的发泡外层或发泡外层与阻隔内层使得发泡内芯与外壳紧密结合,当船体不慎遭受撞击时,有利于将撞击力向四周传递,实现分散作用力以及有利于快速吸收能量,降低外壳破损可能性,显著改善船体的抗冲击性能。
