Problems solved by technology

However, during preparation, free water easily enters the embedded space between heterogeneous composition components (such as hollow glass spheres and epoxy resin), and increases the water absorption rate of the buoyancy material, thus shortening its service life

Embodiment

[0054] The production of the buoyancy material of the embodiment is to firstly use 100 g of hollow glass spheres (average particle size (D 50 ) is 30 μm, and the wall thickness is 1 μm) After maintaining the pressure and adding water for 24 hours, discard the settled hollow glass spheres (ie, broken hollow glass spheres). Then, 500 ml of a 2% sodium hydroxide aqueous solution was added, and the hollow glass spheres were alkali-washed with ultrasonic waves, and then washed with water and dried. Next, the alkali-washed hollow glass spheres were modified with 60 ml of 20 mM aminopropyltriethoxysilane, and then washed and dried to obtain modified hollow glass spheres.

[0055] Then, in a vacuum stirring device (the vacuum degree of this device is maintained at 0.01MPa to 0.1MPa), 50g of modified hollow glass spheres were added to 100g in batches and mixed with alumina particles (the usage amount was 2.2g) , and the particle size is 20 nm) uniformly mixed bisphenol A epoxy resin. ...

Abstract

The invention discloses a composition of a buoyancy material, the buoyancy material and a manufacturing method of the buoyancy material. The buoyancy material composition comprises thermosetting resin, a plurality of micron-sized hollow spheres, a plurality of nano-sized metal oxide particles and a curing agent. Through the roughened surfaces of the hollow spheres and the metal oxide particles, the buoyancy material prepared by the manufacturing method has low water absorption.

Description

technical field [0001] The present invention relates to a buoyant material composition, a buoyancy material and a manufacturing method thereof, and particularly relates to a low water absorption buoyancy material, its composition and its manufacturing method. Background technique [0002] Buoyant materials are widely used in civil, commercial and military fields. For example, the counterweight of underwater equipment, floating cables floating on the water surface or suspended in the water, buoys, submarine cable buried machinery, zero buoyancy support, life-saving devices, submarine detection devices and unmanned remote control submersibles, etc. In addition, with the development of marine technology, high-strength buoyancy materials play an important role in Unmanned Underwater Vehicles (UUVs). Operated Underwater Vehicles, ROV) and autonomous underwater vehicles (Autonomous Underwater Vehicles, AUV) that do not require user operation. [0003] When the buoyant material i...
