Problems solved by technology

At present, most of the lifebuoys commonly used in China are shell-filled lifebuoys, which usually include a buoyant body filled with polyurethane foam. The buoyant body of this shell-filled lifebuoy is usually made of polyethylene plastic However, polyethylene plastic is very sensitive to environmental stress, has poor thermal stability and poor aging resistance, which affects the safety performance and service life of this lifebuoy

Embodiment 1

[0036] As shown in the figure, a lifebuoy includes a buoyant ring body 1 and a polyurethane foam 2 filled in the buoyant ring body 1, wherein the buoyant ring body 1 is a ring body made of sisal wood-plastic composite material, This sisal wood-plastic composite material is mainly composed of the following raw materials, which are prepared and mixed according to the ratio of parts by mass:

[0037] High Density Polyethylene (HDPE) 100 Sisal powder 20

[0038] Glass fiber 4 Foaming agent 2 Coupling agent 1 Plasticizer 3.5 Flame retardant 1.5

[0039] Antifungal agent 0.3 Antioxidant 0.3 Light stabilizer 0.4,

[0040] The buoyant ring body 1 of the lifebuoy of the present invention is made of sisal wood-plastic composite material, and the wood-plastic composite material is a new type of environmental protection material. After adding sisal powder into the high-density polyethylene plastic, the sisal wood-plastic composite material The creep resistance, flexural strength, and fl...

Embodiment 2

[0047] The structure of this embodiment is basically the same as that of Embodiment 1, and the only difference is that the mass and fraction ratios of the raw materials of the sisal wood-plastic composite material used in the buoyant ring body 1 of the lifebuoy of this embodiment are as follows:

[0048] High Density Polyethylene (HDPE) 95 Sisal powder 24

[0049] Glass fiber 3 Foaming agent 2.5 Coupling agent 2 Plasticizer 2 Flame retardant 2

[0050] Antifungal agent 0.1 Antioxidant 0.5 Light stabilizer 0.6.

Embodiment 3

[0052] The structure of this embodiment is basically the same as that of Embodiment 1 and Embodiment 2, and the only difference is that the mass and number ratios of the raw materials of the sisal wood-plastic composite material used in the buoyant ring body 1 of the lifebuoy of the present embodiment are as follows:

[0053] High Density Polyethylene (HDPE) 105 Sisal powder 16

[0054] Glass fiber 5 Foaming agent 3 Coupling agent 1.5 Plasticizer 4 Flame retardant 2.5

[0055]Antifungal agent 0.5 Antioxidant 0.8 Light stabilizer 1.0.

Abstract

The invention discloses a life buoy and a preparation method thereof. The life buoy comprises a buoyant ring body, wherein the buoyant ring body is made of a sisal wood plastic composite material; the life buoy has the advantages that the buoyant ring body is made of the sisal wood plastic composite material; due to the combination of the sisal and glass fiber, the life buoy has extremely high seawater immersion resistance; the life buoy has high thermal stability, aging resistance and bending strength; therefore, the prepared life buoy has high thermal stability, aging resistance, bending strength, creep resistance, bending elastic modulus and the like, the safety performance of the life buoy is greatly reduced and the service life of the life buoy is prolonged simultaneously.

Description

technical field [0001] The invention relates to a water lifesaving equipment and a preparation method thereof, in particular to a lifebuoy and a preparation method thereof. Background technique [0002] Water lifesaving equipment such as lifebuoys are necessary first aid equipment for ships and swimming pools, and are related to personal safety. At present, most of the lifebuoys commonly used in China are shell-filled lifebuoys, which usually include a buoyant body filled with polyurethane foam. The buoyant body of this shell-filled lifebuoy is usually made of polyethylene plastic However, polyethylene plastic is very sensitive to environmental stress, has poor thermal stability and poor aging resistance, which affects the safety performance and service life of this lifebuoy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lifebuoy with simple structure, high safety performance, good heat resistance and stabi...
