specific Embodiment approach 1

[0033] The formulations and material performance indexes of specific embodiments 1-3 are shown in Tables 1, 2 and 3. The following embodiments illustrate: when preparing deep-sea machinable buoyant materials, different resins, different curing agents, and hollow microspheres with different physical properties can be selected to obtain buoyant materials with different density ranges, and the formula can be selected according to actual applications.

[0034]Since the buoyancy material needs to be soaked in water for a long time in actual use, this requires the material to have a low water absorption rate and a short time for water absorption balance; as the depth of use in the water is different, its strength requirements are also different, and the water depth increases, requiring the use of materials. The strength also increases, which requires the material to have a higher hydrostatic pressure resistance under a certain density to ensure the service life.

Abstract

The invention provides a deep-sea machinability solid buoyancy material and its method for preparing, in which the said solid buoyancy material includes epoxide resin; flexibilizer; curing agent; accelerating agent; dispersing agent; deflocculating agent; hollow zeeosphere and coupling agent, and the hollow zeeosphere can be ceramic and/or glass zeeosphere; the hollow of the said hollow glass zeeosphere is filled with gases or vacuum; the weigh parts of the hollow zeeosphere are: 15-90; the weigh parts of the said epoxide resin are: 82-98. The method consists of adding each component into kneader, heating to 80-100 DEG C, agitating to be even; taking-up the even mixtures into the die to consolidate, then laying them into the curing press for heating and forcing, after solidified modeling, producing the needed solid buoyancy material according to the requirement. The buoyancy material can be sawed, dug, grinded, milled and adhibitted and the standard model can be produced to various shapes according to the drawing requirement to meet the application needs.

Description

technical field [0001] The invention relates to a solid buoyancy material suitable for providing buoyancy for deep-sea underwater exploration and manned submersibles and underwater devices for related purposes, and can be applied to underwater depths up to 5800 meters. The invention further relates to a method for the preparation of the solid buoyant material. In particular it relates to the machinability of the buoyant material. Background technique [0002] Solid buoyancy material is a composite material with low density, high strength and less water absorption. It provides sufficient net buoyancy for deep submersible drag bodies, deep submersibles and underwater robots, etc., solves the pressure resistance and structural stability of submersibles underwater, improves the payload of submersibles, and reduces their external dimensions, especially It plays an important role in large-depth submersibles and is an important part of the development of modern deep-diving techno...
