Abstract

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.

Description
