Embodiment 1

[0018] Embodiment 1, the safety vest of this embodiment includes a vest jacket 1 and an inner core 2, and the surface of the inner core 2 is designed as a concave-convex mahjong block suitable for human activity rules. The outer fabric of the outer jacket is made of elastic silk fabric, the surface fabric is two layers, and a layer of SBR material with a thickness of 1mm is sandwiched between the two layers, while the inner fabric is one layer, and the surface is covered with a layer of SBR with a thickness of 1mm. material layer. The inner core 2 is sandwiched in the interlayer of the outer jacket 1. The inner core 2 of the inner core 2 placed in the front outer jacket 1 is at least one third thicker than the inner core 2 placed in the back outer jacket, and its density is 0.07 g / cm 3 The basic composition of the foam material inner core 2 is: 82% of vinyl acetate copolymer, 13% of calcium carbonate filler, 2.3% of azodicarbonamide foaming agent, The foaming aid is 1%, the ...

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, 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 ; furthermore, the safety vest adopts EVA foam as the inner core, the density of the inner core is 0.07g / cm , 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 for various water operation requirements with high fitness performance requirements, such as deck operation, fishery, offshore drilling platform operation and other fields. Background technique [0002] An existing Chinese utility model patent with the patent number CN95221847.X and the name "Safety Vest" discloses a structure, the structure includes the front and the back of the vest. The hard cushion layer and the soft cushion layer between the layer and the inner lining cloth layer are superimposed. The left armpit of the vest is open, not closed, and is connected by male and female nylon stickers or belts. The interlayer of soft cushion is distributed at intervals on the front and back of the vest. The four-layer structure is bonded together with super glue, and the outer lining layer of the vest is caulked or printed with reflective horizontal stripes in striking colors. , It has the advan...
