Abstract

The invention provides a deep-sea pressure-proof machinable buoyancy material, comprising the processing steps of 1) mixing and stirring; preparing materials according to the components; adding the materials to a vacuum kneading machine to evenly stir; 2), stirring and defoaming in vacuum; after mixing and stirring, sealing and covering the vacuum kneading machine to vacuumize, and continuing to stir the materials; 3), discharging, transferring the materials which are stirred and defoamed in vacuum into a die to mold; and 4) demolding, demolding after the materials are thoroughly cured, wherein the materials molded in the die in step 3) also comprise vacuum vibrating defoaming. The material also has the characteristics of low water absorption, and can be used for manufacturing a submersible vehicle in 500-7000m of deep-sea area; and the problems that the similar material in the prior art is large in air bubble content and difficult to remove are solved by a technology which is not complicated through vacuum agitation and vacuum vibrating defoaming technologies in process.

Description

technical field [0001] The invention relates to a solid buoyancy material for an underwater submersible, in particular to a deep-sea pressure-resistant machinable buoyancy material and a production method thereof. Background technique [0002] In recent years, my country's marine technology has developed rapidly, and great progress has been made in marine exploration and monitoring. Deep-water high-strength buoyancy materials have become an important part of the development of modern deep-diving technology. Low-density, high-strength deep-water solid buoyant materials have been used more and more widely, among which machinable buoyant materials have a wider range of applications due to their machinability. [0003] At present, the high-compression and low-density buoyancy materials developed at home and abroad mainly use epoxy resin as a binder, and are filled with a large number of hollow glass microspheres and additives to form lightweight buoyancy materials with excellent...
