The invention discloses a life jacket with a quick-foaming inner core and a preparation method of the inner core of the life jacket. The life jacket comprises an outer sleeve and an inner core playinga role of a floater, the inner core is arranged in the interlayer of the outer sleeve; the formula of the inner core basically comprises the following components of: 0.8-3 parts by mass of sucrose polyether NN4110, 0.4-1.2 parts by mass of ethylenediamine polyether NT403A, 0.04-0.04 parts by mass of a foam stabilizer, 0.025-0.1 parts by mass of an organic tin catalyst DI-12, 0.03-0.08 parts by mass of triethanolamine AR, 0.25-1.1 parts by mass of a flame retardant, 0.04-0.12 parts by mass of cyclopentane and 2-7.5 parts by mass of PAPI PM200. The life jacket has the advantages that after theinner core is immersed in water for 24 hours, the buoyancy loss does not exceed 5%, and a good buoyancy state can be stably kept in water.

    本发明公开了一种带有快速发泡内芯的救生衣及其内芯的制备方法,包括有外套和起浮子作用的内芯,所述内芯置于外套的夹层中,该内芯的配方基本组成为:0.8~3质量份蔗糖聚醚NN4110、0.4~1.2质量份乙二胺聚醚NT403A、0.04~0.15质量份泡沫稳定剂、0.025~0.1质量份有机锡催化剂DY‑12、0.03~0.08质量份三乙醇胺AR、0.25~1.1质量份阻燃剂、0.04~0.12质量份的环戊烷以及2~7.5质量份的PAPI PM200。本发明的优点在于本内芯在水中浸24小时后,其浮力损失不超过5%,在水中能稳定地保持良好的浮力状态。
