The invention relates to a low-density high-buoyancy life buoy, which is prepared from the following raw materials in parts by weight: 37-40% of nitrile rubber, 37-40% of a polyvinyl chloride resin, 0.2-0.4% of a vulcanizing agent, 0.2-0.3% of an accelerator, 0.2-0.3% of a metal soap lubricant, 8-10% of a DOP plasticizer, 11-14% of a foaming agent, and 0.4-1% of a stearate stabilizer, wherein themixing ratio of the nitrile rubber to the polyvinyl chloride resin is 1:1. The life buoy has the advantages that the foam material formed by mixing and compression molding of NBR/PVC with the soft hand feeling density of 0.034 g/cm<3> is adopted, the design is reasonable, the use is safe, the effect is good, and the manufactured life buoy is light in weight, convenient to carry and capable of stably keeping a good buoyancy state in water.
本发明涉及一种低密度高浮力救生圈,所述救生圈由以下重量份的原料制成:丁腈橡胶为37~40%,聚氯乙烯树脂为37~40%,硫化剂为0.2~0.4%,促进剂为0.2~0.3%,金属皂类润滑剂为0.2~0.3%,DOP增塑剂为8~10%,发泡剂为11~14%,硬脂酸盐稳定剂为0.4~1%,所述丁腈橡胶和聚氯乙烯树脂相互混合比例为1∶1,上述百分比为质量百分比。本发明的优点在于:本发明采用手感柔软密度为0.034g/cm3的NBR/PVC混合模压成型的泡沫材料,设计合理,使用安全、效果更好,制成的救生圈重量轻、携带方便在水中能稳定地保持良好的浮力状态。
