Abstract

The invention relates to an ultraviolet-proof life buoy. The life buoy is prepared from the following raw materials in parts by weight: 80-120 parts of a low-density polyethylene resin, 12-15 parts oflight 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 ultravioletlight absorber. The ultraviolet-proof life buoy has the advantages that the life buoy is hard in surface and is made of a closed-cell foam material, so that air leakage caused by puncture is avoided,good floating force can be kept for a long time, and the ultraviolet-proof life buoy is safe and reliable compared with the inflatable life buoy; and the ultraviolet light absorber is added to prevent premature aging of the lifebuoy.

Description

technical field [0001] The invention relates to an anti-ultraviolet life buoy, 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] Lifebuoy refers to a kind of water lifesaving equipment, usually made of cork, foam plastic or other light materials with small specific gravity, and covered with canvas, plastic and so on. Life buoys for swimming practice can also be made of rubber and filled with air, also known as rubber rings. However, the existing swimming rings used for entertainment are often damaged and leaked, and the compression resistance is very poor. The surface is wet and slippery when exposed to water, and is difficult to grasp. It is dangerous and poses a serious threat to the safety of users. Therefore its structure still needs to be improved. Contents of the invention [0003] The technical problem to be ...
