Abstract

The invention discloses a durable elastic floating body and a preparation method thereof, and belongs to the technical field of high polymer materials. The durable elastic floating body comprises an ethylene-vinyl acetate copolymer, a thermoplastic elastomer TPE, a filler, a foaming agent, a foaming aid, a lubricant, a coupling agent modified anti-ultraviolet agent, a coupling agent modified antioxidant, a coupling agent modified antibacterial agent, a cross-linking agent and a pigment. According to the durable elastic floating body, the surfaces of the anti-ultraviolet agent, the antioxidantand the antibacterial agent are changed into hydrophobicity from hydrophilcity through modification of the coupling agent, the dispersity of an inorganic auxiliary agent in an organic material is improved, the binding force of the inorganic auxiliary agent and the organic material is enhanced, the effect of the inorganic auxiliary agent can be fully exerted, the obtained elastic floating body hasexcellent wear resistance, rebound resilience, antibacterial property and aging resistance at the same time. The preparation method is simple in step and easy to operate, and the elastic floating bodyis formed through one-time foaming, compact in texture, smooth and thorn-free in surface and excellent in quality.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a durable elastic floating body and a preparation method thereof. Background technique [0002] The float is a foam material. Foam materials have the advantages of light weight, heat insulation, attraction, and heat insulation, so they are widely used in various fields such as transportation and construction. Floating bodies are often used to prepare offshore working tools, such as buoys, buoys, life jackets, buoys, floating rafts, buoys, etc. These tools are installed on the sea surface or near sea water, and are subject to seawater corrosion and ultraviolet radiation for a long time, and are susceptible to microorganisms. Erosion, lack of durability, easy aging issues, and color fades easily. At the same time, although this type of elastic floating body has good floating performance, its wear resistance is poor and its resilience is insufficient, resulti...
