Deep-sea pressure-proof machinable buoyancy material and production method thereof

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...

AI Technical Summary

Problems solved by technology

[0004] Chinese patent CN200610043524.4 introduces a kind of epoxy resin as the matrix, filled with hollow glass microspheres and / or ceramic microspheres, after stirring evenly in a kneader, the mixture is put into a mold, compacted, and placed under pressure In the curing machine, pressurize and heat, and cure for a certain period of time to obtain a material standard module. The density of this type of material is 0.5 g / cm 3 Below, pressure resistance 12.5Mpa, density 0.6 g / cm 3 The material can be used in 5,800-meter deep-water operations, and its comprehensive performance is relatively excellent, but its production process is relatively complicated. After the materials are mixed and stirred, they are transferred to the mold for compaction, and then placed in a pressure curing machine to pressurize and heat to compress the air bubbles. cured after shrinking

[0006] In the above methods, the degassing of materials requires high temperature and high pressure conditions, or special and complicated molds and demoulding devices. The processes are relatively complicated, the production cost is high, and the efficiency is low, which is greatly restricted.
