The invention discloses a safety vest with a nitrile butadiene rubber foaming inner core. The safety vest comprises a vest outer sleeve and an inner core, wherein the inner core is clamped in the interlayer of the outer sleeve, the formula of the foaming material inner core basically comprises the following components: 37-40% of a nitrile butadiene rubber, 37-40%of a polyvinyl chloride resin, 0.2-0.4% of a vulcanizing agent, 0.2-0.3% of a promoter, 0.2-0.3% of a metallic soap lubricant, 8-10% of a DOP plasticizer, 11-14% of a foaming agent and 0.4-1% of a stearate stabilizer, and a mixing ratio of the nitrile butadiene rubber to the polyvinyl chloride resin is 1:1. According to the invention, the safety vest has the advantages that the nitrile butadiene rubber foam with the density of 0.07g/cm<3> is adopted, so that the safety vest can be used as a life jacket and can resist high-strength external force impact; and the inner core has a good floating effect, so that the manufactured safety vest can be used as a 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丁腈胶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,该发泡材料内芯的配方基本组成为:丁腈橡胶为37~40%,聚氯乙烯树脂为37~40%,硫化剂为0.2~0.4%,促进剂为0.2~0.3%,金属皂类润滑剂为0.2~0.3%,DOP增塑剂为8~10%,发泡剂为11~14%,硬脂酸盐稳定剂为0.4~1%,所述丁腈橡胶和聚氯乙烯树脂相互混合比例为1∶1,上述百分比为质量百分比;本发明的优点在于采用密度为0.07g/cm3的丁腈胶泡沫,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。
