Children swimming ring and preparation method thereof

The invention relates to a children swimming ring and a preparation method thereof. The children swimming ring is prepared from, by weight, 80-120 parts of low-density polyethylene resin, 12-15 parts of light calcium carbonate, 0.8-1.2 parts of a cross-linking agent, 22-30 parts of a foaming agent, 1.5-3.5 parts of zinc stearate, 0.12-0.18 part of an antioxidant, and 0.12-0.18 part of an ultraviolet absorber. The children swimming ring is hard on surface, air leakage due to sting damage cannot occur due to the closed-cell foam material of the ring, good floating force can be sustained for a long term, and the children swimming ring is safe and reliable as compared with an inflatable life buoy, thereby being an ideal children swimming apparatus. 本发明涉及种儿童游泳圈及其制备方法，由以下重量份的原料制成：低密度聚乙烯树脂80-120；轻质碳酸钙12-15；交联剂0.8-1.2；发泡剂22-30；硬脂酸锌1.5-3.5；抗氧化剂0.12-0.18；紫外光吸收剂0.12-0.18。本发明表皮坚硬，因是闭孔发泡材料，不会因刺损而漏气，故能长久地保持较好的漂浮力，比充气式救生圈安全可靠，是种理想的儿童泳具。
