The invention discloses a life jacket with a high-toughness 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 playing a role of a floater, wherein the inner core is arranged in the interlayer of the outer sleeve and is prepared from the following raw materials in parts by weight: 80-120 parts of EVA, 0.8-1.2 partsof a cross-linking agent, 22-30 parts of a foaming agent, 1.5-3.5 parts of zinc oxide, 0.12-0.18 parts of tribasic lead sulfate, 0.15-0.19 parts of a release agent stearic acid and 10-18 parts of calcium carbonate. The processing technology is simple, the life jacket is good in wear resistance and not prone to tearing, the impact strength, the tensile strength and the elongation at break of EVA can be obviously improved due to addition of calcium carbonate, and the life jacket has obvious toughening and reinforcing effects on materials.
本发明公开了一种带有高韧度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,该内芯由以下重量份的原料组成:EVA 80~120、交联剂0.8~1.2、发泡剂22~30、氧化锌1.5~3.5、三盐基性硫酸铅0.12~0.18、脱模剂硬脂酸0.15~0.19,碳酸钙10~18。本发明加工工艺简单,而且救生衣耐磨性好、不易撕裂,碳酸钙的加入能明显提EVA的冲击强度、拉伸强度和断裂伸长率,对材料具有明显的增韧、增强作用。
