The invention belongs to the technical field of underwater lifesaving, and particularly relates to a long-acting buoyancy body, an offshore lifesaving device and a manufacturing method thereof. High-density NBR foamed cotton serves as an inner container of the long-acting buoyancy body and is put into the TPU outer sleeve, and the interface edge of the TPU outer sleeve is seamlessly jointed by adopting a high-frequency hot melting process in the field of chemical engineering. According to the life jacket manufactured by the long-acting buoyancy body provided by the invention, the marine life-saving device can keep continuous large buoyancy after being soaked in seawater for a long time; in addition, the problem that the life jacket is damaged, mildewed and smelly due to the fact that lines at the sewing position of a sewing machine of a traditional life jacket are soaked and rotten is solved. Meanwhile, by means of the manufacturing process of the life jacket, a simple and attractive life-saving rescue equipment product can be provided.

    本发明属于水下救生技术领域,更具体地涉及一种长效浮力体、海上救生装置及其制造方法。本发明将高密度NBR发泡棉作为长效浮力体的内胆放入TPU外套内部,采用化工领域的高周波热熔接工艺使TPU外套的接口边缘无缝接合。采用本发明提供的长效浮力体制造的救生衣、海上救生装置除了具备长时间浸泡在海水中能够保持持续大浮力以外,还解决了传统救生衣的针车缝合处线条浸泡发烂导致救生衣破损和发霉发臭的问题。同时,本发明救生衣的制造工艺能够提供简洁、美观的救生救援装备产品。
