Technical Field

The invention relates to the technical field of water floating bodies, in particular to a graphene floating body for a water floating system.

Background

The floating body is a hollow or solid structure which can float on the water surface and has a certain bearing capacity, is mostly made of High Density Polyethylene (HDPE) or other plastic materials at present, and is widely applied to the fields of water photovoltaic power stations, water floating paradises, water floating bridges, water wharfs, water floating platforms, water floating swimming pools, water floating houses, water floating parks, water floating resorts, water floating cities, water floating airports, water floating islands, water culture, marine ranches or floating stages and the like.

The large number of plastic floats used in the above projects require long-term exposure to ultraviolet light and sunlight. The exposed plastic is easy to burn and deform due to the lower burning point of the plastic, so that certain potential safety hazards exist.

In addition, because the common plastics such as polyethylene, polypropylene or polyvinyl chloride have the characteristics of low strength, poor aging resistance and large surface resistance, when the plastics are subjected to external force (such as impact force of strong wind, large waves, flood and the like), the floating body is easy to deform to cause the failure of the floating body. The plastic floating body applied to the lake surface or the river channel is easy to generate damp-heat aging on the part immersed in water for a long time, and the part under the irradiation of sunlight is easy to generate aging due to heating, so that the service life of the floating body is shortened. Meanwhile, because the resistance of the plastic surface is large, static electricity is easily generated on the surface of the plastic floating body due to the accumulation of a large amount of charges, and certain potential safety hazards exist if the plastic floating body is easily burnt and deformed by naked fire.

In addition, a large amount of mould, yeast, algae, shells and the like in the plastic floating body soaked in fresh water or seawater for a long time can be attached to the floating body, so that the self weight of the floating body is continuously increased, the buoyancy of the floating body is greatly reduced, and the service life of the floating body is influenced.
