The invention discloses a high-buoyancy high-elasticity life jacket and a preparation method of the inner core of the high-buoyancy high-elasticity life jacket. The high-buoyancy high-elasticity lifejacket comprises an outer sleeve and an inner core with floater effect, wherein the inner core is arranged in the interlayer of the outer sleeve, the formula of the inner core basically comprises 45-60 parts of a SEBS thermoplastic rubber, 8-12 parts of an EPDM rubber, 12-18 parts of a POE rubber, 3-6 parts of a TPE rubber, 1-3 parts of color masterbatch, 2-5 parts of a calcium carbonate filler, 1-3 parts of pot clay, 6-10 parts of softening oil, 2-4 parts of a foaming agent, 1-2 parts of zinc oxide powder and 1-3 part of a cross-linking agent. The inner core disclosed by the invention has thecharacteristics of good elasticity, strong toughness, good aging resistance, strong buoyancy and the like, and can be used as a cushion material, an absorbent material, a buoyancy material and the like required by various industries, so that the density and the hardness of the inner core are lower than the density and the hardness of similar products on the market, the buoyancy is strong, the elasticity is good, and the inner core is suitable for being used on life jackets.

    本发明公开了一种高浮力高弹性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:SEBS热塑性橡胶45~60,EPDM橡胶8~12,POE橡胶12~18,TPE橡胶3~6,色母1~3,碳酸钙填充剂2~5,陶土1~3,软化油6~10,发泡剂2~4,锌氧粉1~2,交联剂1~3。本发明的内芯具有弹性好、韧性强、耐老性好、浮力强等特性,可以作为各行业所需要的缓冲垫料、吸性材料及浮力材料等应用,使其在密度、硬度上比市面上的同类产品更低,浮力更强,弹性更好,非常适合在救生衣上使用。
