Abstract

The invention relates to a safety vest which comprises a vest overcoat (1) and an inner core (2). The inner core (2) is arranged in the interlayer of the overcoat (1). The safety vest is characterized in that the inner core (2) is made of foam material foamed by EVA with the density being of 0.07g / cm<3>, and the formula of the foam material inner core (2) comprises the following basic components:82 to 83 percent of ethylene-vinlacetate copolymer, 11 to 13 percent of calcium carbonate filling agent, 2.3 to 4.3 percent of azodicarbonamide foaming agent, 0.6 to 1 percent of foam boosting agent,0.5 to 0.7 percent of cross-linking agent, and 0.6 to 1 percent of stearic acid lubricant. Compared with the prior art, the invention has the advantages that the safety vest can not only be used as a life vest, but also be capable of resisting high-strength external force impact by adopting the EVA foam with the density being of 0.07g / cm<3>; furthermore, the safety vest adopts EVA foam as the inner core, the density of the inner core is 0.07g / cm<3>, and the inner core has good floating effect, therefore the safety vest can be used as a life vest in case of emergence, and can meet the demands of various water operations with higher requirements for fitness performance, such as deck operation, fishing, offshore drilling platform operation and the like.

Description

technical field [0001] The invention relates to a safety vest, which can be used in various water operations requiring high fitness performance, such as deck operations, fisheries, offshore drilling platform operations and other fields. Background technique [0002] Existing a kind of patent No. is CN95221847.X name is called " safety vest " Chinese utility model patent discloses a kind of structure, and its structure comprises vest front, back, and this vest is made of outer lining cloth layer, inner lining cloth layer and be placed in outer lining cloth layer. The hard cushion layer and the soft cushion layer between the layer and the lining cloth layer are superimposed. The left armpit of the vest is open and not closed. It is connected by male and female nylon sticks or belts. In addition, the hard cushion layer and The interlayer formed by the soft cushion layer is distributed on the front and back of the vest at intervals. This four-layer structure is glued together wi...
