The invention relates to a rigid foam plastic life buoy. The life buoy is prepared from the following raw materials in parts by weight: 70-100 parts of low density polyethylene, 10-20 parts of a polyvinyl chloride resin, 8-10 parts of magnesium oxide, 15-20 parts of a foaming agent, 0.3-0.8 part of a cross-linking agent, 4-8 parts of zinc oxide, 2-3 parts of stearic acid, 0.2-0.4 part of an antioxidant, 0.3-0.6 part of an activating agent, 0.5-0.8 part of a plasticizer, 0.3-0.8 part of a cross-linking catalyst and 0.5-1 part of an anti-aging agent. According to the rigid foam plastic life buoyof the invention, the manufacturing cost is low, the material is soft, comfortable to wear and good in fastness, the condition that the floating performance of the life buoy is affected due to puncture is not easily generated, the life buoy is high in oxidation resistance, abrasion resistance and aging resistance and capable of greatly prolonging the service life, the used raw materials are non-toxic, low-toxicity and environment-friendly raw materials, the dual requirements for safety and environmental protection are met, the production process is simple, the raw materials are easy to obtain, and the industrialization degree is high.

    本发明涉及一种硬质泡沫塑料救生圈,所述救生圈由以下重量份的原料制成:低密度聚乙烯70~100份,聚氯乙烯树脂10~20份、氧化镁8~10份,发泡剂15~20份,交联剂0.3~0.8份,氧化锌4~8份,硬脂酸2~3份,抗氧剂0.2~0.4份、活化剂0.3~0.6份、增塑剂0.5~0.8份、交联催化剂0.3~0.8份、防老剂0.5~1份。本发明提供的救生圈,不仅造价成本低,材质较为柔软、穿着舒适、牢度好,不容易刺破而影响其漂浮性能,并且其抗氧化、耐磨损、耐老化能力强,大大延长了其使用寿命,所用原料均为无毒低毒环保原料,满足了对安全和环保的双重要求,此外生产工艺简单,原料易得,可工业化程度高。
