Abstract

The invention discloses a high-strength solid buoyancy material for a deep sea and a preparation method thereof. The high-strength solid buoyancy material disclosed by the invention comprises the following components in parts by weight: 100 parts of epoxy resin, 10-80 parts of grafted and modified hollow glass micro-bead, 10-20 parts of thinner, 50-80 parts of curing agent and 0.1-3 parts of catalyst; the high-strength solid buoyancy material for a deep sea and the preparation method thereof disclosed by the invention are characterized in that the grafted and modified hollow glass micro-bead is grafted and modified by adopting the surface-initiated ATRP (Atom Transfer Radical Polymerization) polymerization method; polymethylacrylic acid glycidyl ester polymer is grafted on the surface of the hollow glass micro-bead; the modification method has the advantages of few steps, low cost and simple process; furthermore, by means of grating and modifying, the dispersity and the compatibility of the hollow glass micro-bead in an epoxy substrate can be improved; in addition, the epoxy group at the side group of the grafted polymer is solidified together with the epoxy resin substrate, and therefore the prepared solid buoyancy material is high in strength and the use depth reaches 7000-10000m so that the prepared solid buoyancy material can meet requirements of ocean development and submarine detection.

Description

technical field [0001] The invention relates to a solid buoyancy material for buoyancy provided by deep-sea underwater exploration and manned submersibles and related underwater devices, belonging to the technical field of functional non-metallic materials, in particular to a high-strength solid buoyancy material for deep sea and its Preparation. Background technique [0002] In recent years, solid buoyancy materials have been widely used in marine development equipment such as offshore oil production risers and underwater operating submersibles. As humans explore the underwater world and dive deeper and deeper, the strength requirements for solid buoyancy materials are also getting higher and higher, so as to ensure the safe use of deep-water equipment. [0003] Based on the rich resources in the deep sea and the development of military equipment, various countries have invested heavily in the development and research of solid buoyant materials for deep sea, and there are ...
