The invention discloses a safety vest with a polyethylene foaming inner core. The vest comprises a vest coat and an inner core, the inner core is clamped in the interlayer of the outer sleeve; the inner core is made of a foam material formed by foaming polyethylene with the density of 0.07 g/cm; the foaming material inner core is basically composed of 10%-50% of polyethylene, 2.3%-4.3% of an azodicarbonamide foaming agent, 0.6%-1% of a foaming aid, 0.5%-0.7% of a cross-linking agent, 0.6%-1% of a stearic acid lubricant and the balance calcium carbonate filler. The safety vest has the advantages that the polyethylene foam with the density of 0.07 g/cm3 is adopted, so that the safety vest can be used as the life jacket and can resist high-strength external force impact; and due to the fact that the inner core has a good floating effect, the manufactured safety vest can be used as the life jacket in emergency, and can be used for various overwater operation requirements with high requirements for fitness performance.

    本发明公开了一种带有聚乙烯发泡内芯的安全背心,包括有背心外套和内芯,所述内芯为夹置于外套的夹层中,所述内芯采用密度为0.07g/cm的聚乙烯发泡而成的泡沫材料,该发泡材料内芯的配方基本组成为:聚乙烯为10~50%,偶氮二甲酰胺发泡剂为2.3~4.3%,发泡助剂为0.6~1%,交联剂为0.5~0.7%,硬脂酸润滑剂0.6~1%,碳酸钙填充剂余量;本发明的优点在于采用密度为0.07g/cm3的聚乙烯泡沫,实现了既能作救生衣又抵抗高强度外力冲击的安全背心;因该内芯具有良好浮水作用,所以制成的安全背心在紧急情况下能充当救生衣之用,可用于各种对适体性能要求较高的水上作业需求。
