Problems solved by technology

The characteristic of this kind of life jacket is that it is made of breathable material, so it has better ventilation when worn, but its disadvantage is that this kind of breathable material has good water resistance. If the bubble sinks in the water for too long, its buoyancy will lose Decline; also its buoyancy is only concentrated on the chest, the back is just a strap, the structure is not firm enough, the buoyancy is not fully utilized, and its heat preservation effect is not good; so its structure and materials need to be improved

Abstract

The invention discloses a life jacket comprising a jacket and an inner core which can be used as a floater. The inner core is placed in an interlayer of the jacket; the inner core is made of a foam material which is obtained by foaming main raw materials including butadiene-acrylonitrile rubber and polyvinyl chloride; the formulation of the inner core is basically composed of 10-25% of the butadiene-acrylonitrile rubber, 40-60% of polyvinyl chloride resin, 0.1-0.3% of vulcanizing agent, 0.2-0.3% of metal soap lubricating agent, 6-12% of plasticizer, 10-20% of foaming agent and 0.5-1% of stearate stabilizing agent. The life jacket disclosed by the invention has the advantages that after the inner core is immersed in water for 24 hours, the buoyancy loss is not more than 5%, so that the life jacket can stably keep a good buoyancy state in the water; the material of the inner core has a soft hand feel, and the life jacket not only has good fitness after being worn on the body, but also is convenient for people to bend, crouch or carry out various activities; the density of the inner core is only 0.034 g / cm<3> and the weight of each piece of the prepared life jacket is less than or equal to 0.8 kg, so that the weight of the life jacket is light and the life jacket is convenient to carry.

Description

technical field [0001] The invention relates to a lifejacket, which is used for fishing in sea, river and lake, for entertainment such as riding a yacht, or for marine engineering operations, and for floating the user's body when a water disaster occurs. Background technique [0002] An existing patent No. CN200610001478.1, a Chinese invention patent titled "Lifejacket", discloses a structure that has left and right front bodies, and the central upper part between the two front bodies is located near the rear lower part of the user's neck , wherein, above the parts of the two front bodies that are in contact with the user's chest, and the inner surface of the upper central part are all made of air-permeable materials from approximately the inner edge to the approximately outer edge. The breathable material can be selected from mesh material, which has a certain thickness to obtain cushioning. In addition, air-permeable non-slip materials can be provided at appropriate posit...
