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
The present invention relates to a kind of safety vest, can be used for the various operation at sea demands higher, as fields such as deck operation, fishery, offshore drilling platform operations to fit performance requirement.
Background technology
Existing a kind of patent No. discloses a kind of structure for the Chinese utility model patent that the CN95221847.X name is called " safety vest "; its structure comprises the vest front; the back side; this vest is by the outer lining layer of cloth; internal lining cloth layer and place hard bed course and soft bed course between outer lining layer of cloth and internal lining cloth layer to be formed by stacking; the oxter, the left side of vest is an opening; do not seal; adopt the sticking or belt of female male nylon to link; the interruption-like vest front that is distributed in of interlayer that constitutes by hard bed course and soft bed course in addition; the back side, this four-layer structure adopt seccotine to be bonded together, filleting or be printed on the alternate horizontal stripe of conspicuous color with reflecting effect on vest outer lining layer of cloth; it has simple in structure; dress is convenient, and safe and reliable grade is that motorcyclist minimizing accident takes place, a kind of safety-type vest of protection human body safety.Though but this vest can be resisted the impact of strong external force, it is overcoming the shock proof while, and the action of wearing personnel is but very inconvenient; And it can not make the usefulness of life vest, so the scope of application is very little, so its structure awaits to improve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of at above-mentioned prior art present situation can make the safety vest that life vest can be resisted external impacts.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the safety vest, include vest overcoat and inner core, and described inner core is to be folded in the interlayer of overcoat, it is characterized in that: it is 0.07g/cm that described inner core adopts density
3The foamed material that forms of EVA foaming, the prescription of this expanded material inner core basic composition is: acetate ethylene copolymer is 82～83%, calcium carbonate-filled dose 11～13%, azodicarbonamide foaming agent is 2.3～4.3%, blowing promotor is 0.6～1%, and crosslinking agent is 0.5～0.7%, stearic acid lubricant 0.6～1%, above-mentioned percentage is mass percent, and described EVA is meant acetate ethylene copolymer.
Improve, described overcoat (2) face cloth is for playing terylene cloth again, and its face cloth is two layers, and is gripped with the SBR material layer that thickness is 0.9～1.1mm between two layers, and lining is one deck, and it is the SBR material layer of 0.9～1.1mm that surface coverage has a layer thickness.
Improve, the safety vest is designed to the blouse vest again, is provided with the connecting band on two sides, the chest face and back side front and back at two waist places, and this connecting band and overcoat are the overall structure that integral production forms.
As further improvement, described inner core places overcoat interior inner core in shirtfront than the inner core thick at least 1/3rd that places in the overcoat of back.People's health moves to and recedes thereby the distribution of vest buoyancy can will be fallen into water in 10S, becomes the angle of 20～50 degree from vertical line, and makes its mouth exceed the floating position of safety of water surface 12cm.
Improve, its surface of described inner core is for being suitable for the concavo-convex mahjong fmt chunk of physical activity rule again.
Improve, the preparation method of described inner core material may further comprise the steps again:
A, according to the recipe configuration raw material;
B, be in the refiners of 110～120 degree mixing 20～30 minutes with the raw material that configure in temperature then, putting into temperature after then the material after mixing being taken out is that 90～100 mills of spending mixed 24～26 minutes, open refining and finish the back according to product requirement cutting raw material, it is that 165～175 degree moulds foamed 35～40 minutes that temperature is put in tiling, cooled off then 29～31 minutes, promptly obtaining density is 0.07g/cm
3Inner core material.
Compared with prior art, the invention has the advantages that adopting density is 0.07g/cm
3Eva foam, this density is whole key index, the little buoyancy of density has solved but can not resist HI high impact, can shock resistance but buoyancy is too little and density is big, found the critical point 0.07g/cm of this density finally by us through research for a long time
3, realized to make the safety vest that life vest is resisted the high strength external impacts again; Also have, its surface of inner core of the present invention is for being suitable for the concavo-convex mahjong fmt chunk of physical activity rule; Overcome and worn safety vest in the past and overcoming shock proof handicapped problem of wearing personnel simultaneously; Moreover it is inner core that the safety vest adopts the eva foam material, and the density of inner core is 0.07g/cm
3,,, can be used for the various operation at sea demands higher, as deck operation, fishery, offshore drilling platform operation etc. to fit performance requirement so the safety vest of making in case of emergency can serve as the usefulness of life vest because of this inner core has the effect of well swimming.
