Abstract

The invention discloses a life jacket with an antibacterial inner core and a preparation method of the inner core of the life jacket. The life jacket comprises an outer sleeve and an inner core playing a role of a floater, wherein the inner core is arranged in the interlayer of the outer sleeve, and the inner core is prepared from the following components in parts by weight: 80-100 parts of an ethylene-vinyl acetate copolymer, 5-10 parts of an ethylene-acrylic acid copolymer, 6-12 parts of a polyolefin elastomer, 0.5-1 part of a cross-linking agent, 0.5-1 part of barium stearate, 10-15 parts of a microcapsule foaming agent, 5-8 parts of an antistatic agent, 1-3 parts of nano titanium dioxide and 2-4 parts of parachloro dimethyl phenol. The antibacterial EVA foam material disclosed by the invention is soft in texture, smooth in surface and good in resilience and shock resistance, and has good antibacterial and antistatic functions.

Description

technical field [0001] The invention relates to a lifejacket, which can be used in various water operations that require high fitness performance, such as deck operations, fisheries, offshore drilling platform operations and other fields. Background technique [0002] As a common tool in the field of water operations, life jackets are generally disclosed in the Chinese utility model patent: Super Buoyancy Life Jacket (Patent No. CN93214217.6). Its structure uses a novel waterproof and flame-retardant fabric to form a "life jacket". The inner and outer layers, the interlayer between the inner and outer layers has a specially treated non-absorbent, flame-retardant high-density polyethylene foam material interlayer, which is sewn into two pieces of chest and back in a specific form. The nylon high-strength webbing of the sub-shaped buckle is stitched together as a whole. The utility model has the advantages of being safe and reliable, super buoyant and warm, simple in structur...
