The invention discloses a life jacket with a high-temperature-resistant and cold-resistant inner core and a preparation method of the inner core of the life jacket. The life jacket comprises an outersleeve and an inner core playing a role of a floater, and the inner core is arranged in the interlayer of the outer sleeve; the formula of the inner core basically comprises the following components of: 45-55 parts of low-density polyethylene, 20-30 parts of high-density polyethylene, 10-12 parts of calcium carbonate, 2-4 parts of soap powder, 3-5 parts of glass fibers, 3-5 parts of a foaming agent, 22-25 parts of a light inorganic filler, 1-3 parts of a dispersing agent, 4-6 parts of azodicarbonamide, 0.5-0.8 parts of a heat stabilizer and 40-45 parts of water. The life jacket has the advantages that the inner core is good in cold-resistant and high-temperature-resistant effect and beneficial to environmental protection, after the inner core is soaked in water for 24 hours, the buoyancy loss of the inner core does not exceed 5%, and a good buoyancy state can be stably kept in water.

    本发明公开了一种带有耐高温耐寒内芯的救生衣及其内芯的制备方法,包括有外套和起浮子作用的内芯,所述内芯置于外套的夹层中,该内芯的配方基本组成为:低密度聚乙烯45~55份、高密度聚乙烯20~30份、碳酸钙10~12份、肥皂粉2~4份、玻璃纤维3~5份、发泡剂3~5份、轻质无机填充料22~25份、分散剂1~3份、偶氮二甲酰胺4~6份、热稳定剂0.5~0.8份、水40~45份。本发明的优点在于本内芯抗寒耐高温效果好,有利于环境保护,在水中浸24小时后,其浮力损失不超过5%,在水中能稳定地保持良好的浮力状态。
