Small fiber balls for solid buoyancy material and preparation method of small fiber balls

Abstract

The invention discloses small fiber balls for a solid buoyancy material and a preparation method of the small fiber balls. The small fiber balls have nuclear shell structures, nucleating carriers are foam balls, and shell layers are powdery fiber reinforced resin matrix composite layers; the small fiber balls with the nuclear shell structures are prepared by adopting the expandable polystyrene foam balls as the nucleating carriers, uniformly coating the surfaces of the expandable polystyrene foam balls with powdery fiber reinforced resin systems, solidifying and washing. The physical performance of the small fiber balls can be conveniently and effectively controlled and improved by changing the foam diameter, the fiber and resin type and the coating thickness according to different environmental usage requirements.

Description

technical field

[0001] The invention relates to a fiber pellet used for solid buoyancy materials and a preparation method thereof, in particular to a counterweight for equipment in water, water surface buoys, deep-sea exploration, and deep-sea oil and gas field development platforms applicable to water depths up to 3,000 meters and above A fiber pellet of solid buoyancy material used in a buoyancy platform and a preparation method thereof. Background technique

[0002] Solid buoyancy material is a high-performance composite material with low density, high strength, low water absorption and high buoyancy. It is an indispensable basic material for modern offshore oil, natural gas and deep diving technology. It can provide buoyancy for platform devices on the water surface , provide thermal insulation and buoyancy for underwater pipelines, provide necessary buoyancy for deep-diving equipment, and play an important role in increasing the payload of the submersible, reducing its ...
