High-strength solid buoyancy material used in deep sea and preparation method of high-strength solid buoyancy material

Abstract

The invention discloses a high-strength solid buoyancy material used in deep sea and a preparation method of the high-strength solid buoyancy material. The high-strength solid buoyancy material comprises the following components in parts by mass: 10-30 parts of epoxy resin, 1-3 parts of an anti-impact agent, 3-5 parts of a curing agent, 4-6 parts of a solvent, 5-15 parts of hexamethyl phosphoramide, 6-8 parts of a catalyst, 5-15 parts of hollow glass beads, 10-20 parts of inorganic packing, 6-8 parts of calcium stearate, 4-8 parts of aluminum oxide, 15-25 parts of a toughening agent, 10-12 parts of an amino silane coupling agent and 2-4 parts of a diluent. The high-strength solid buoyancy material has the advantages of being small in number of steps, low in cost and simple in process, in addition, the dispersibility and the compatibility of the hollow glass beads in an epoxy substrate can be improved through grafting modification, and furthermore, epoxy groups of a polymer base are cured with the epoxy resin substrate, so that the strength of the prepared solid buoyancy material can be high, the use depth of the prepared solid buoyancy material can be up to 7000-10000m, and requirements of ocean development and seabed exploration can be met.

Description

technical field [0001] The invention relates to the field of artificial materials, in particular to a high-strength solid buoyancy material for deep sea and a preparation method thereof. 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 many reports on the preparation methods of solid buoyant materials, such as US Patents USP4,021,589, USP5,973,031, etc. Reported a buoyant material prepared by fi...

AI Technical Summary

Problems solved by technology

The hollow microspheres in the prepared material are easy to disperse unevenly, and the compatibility with the polymer matrix is ​​not good, and the interfacial bonding force is not strong, which makes the material prone to defects and makes the overall strength of the material not high, thus Limits its use on large marine deepwater equipment
