Abstract

The invention relates to a reinforced polystyrene foam ball which comprises a core-shell structure, the core of the core-shell structure is a polystyrene foam ball, and the shell layer of the core-shell structure is a thermosetting resin layer blended with fibers and optionally blended with hollow glass beads. Hollow glass beads can be selectively added into a coating layer of the polystyrene foam ball, so that the density of the reinforced polystyrene ball is reduced to a certain extent, and the strength requirement of the reinforced polystyrene ball during application is met.

Description

technical field [0001] The invention relates to the field of lightweight materials, in particular to a reinforced polystyrene foam ball and a preparation method thereof. Background technique [0002] The floating body for marine equipment is mainly a composite material by adding hollow glass microspheres to a resin matrix through a certain preparation technology. Since the beginning of the 21st century, countries around the world have carried out large-scale exploration and exploitation of mineral resources in the marine field. As an important supporting material for deep-sea equipment, solid buoyancy material provides buoyancy for deep-sea equipment. The density of the material is mainly reduced by adding hollow glass beads, and the density can be as low as 0.35g / cm 3 , It is difficult to reduce the density of buoyancy materials by further increasing the amount of hollow glass microspheres added. Polystyrene foam balls have low density and large volume. Reinforcing them ca...
