preparation example Construction

[0031] The present invention also provides a preparation method for the above-mentioned deep-sea flexible buoyancy material, comprising the following steps:

[0032] (1) hollow microspheres, liquid rubber, vulcanizing agent are mixed by the mass ratio of 100:(130-200):(0.2-3), after vacuum degassing, obtain compound;

[0033] (2) Inject the mixture into the mold and apply a pressure of 1-3MPa;

[0034] (3) The mixed material is vulcanized under the applied pressure to obtain the deep-sea flexible solid buoyancy material.

[0035] In this article, the term "vulcanizing agent" is sometimes also called curing agent, which refers to a substance that can make linear molecules bond and cross-link each other to form a network structure, including but not limited to sulfur. Further, according to the needs of vulcanization, during the vulcanization process, auxiliary agents such as accelerators and active agents can also be added. For example, it can be added in a ratio of hollow mic...

Embodiment 1

[0040] (1) Hollow glass microspheres (US 3M company, HGS8000X, density 0.42g / cm3 ) 2000g, liquid nitrile rubber (LNBR820, Shanghai Pinsheng Chemical Co., Ltd.) 2600g, sulfur 4g, tetramethylthiuram disulfide 50g and zinc oxide 40g (mass ratio is 100:130:0.2:2.5:2) machinery Stir to mix, then vacuum degass for later use.

[0041] (2) Put the above mixture into a mold and pressurize to 2MPa.

[0042] (3) Under the pressure of 2MPa, vulcanize according to the vulcanization process of 85°C for 30 minutes, then 115°C for 60 minutes, and finally 160°C for 120 minutes. After the vulcanization is completed, the vulcanized material is taken out from the mold to obtain the deep-sea flexible solid buoyancy material.

Embodiment 2

[0044] (1) Hollow glass microspheres (US 3M company, HGS8000X, density 0.42g / cm 3 ) 2000g, liquid silicone rubber (Shenzhen Hongyejie Technology Co., Ltd., 620A) 2600g, special curing agent (Shenzhen Hongyejie Technology Co., Ltd., 620B) (vulcanizing agent) 30g (mass ratio is 100:130:1.5) mechanical stirring Mixed and degassed under vacuum for later use.

[0045] (2) Put the above mixture into a mold and pressurize to 3MPa.

[0046] (3) Place it at room temperature under the above pressure for 10 hours to cure. After the curing is completed, the cured material is taken out from the mold to obtain the deep-sea flexible solid buoyancy material.

Abstract

The embodiment of the invention provides a deep sea flexible buoyancy force material, which comprises vulcanized liquid rubber and hollow micro beads dispersed in the vulcanized liquid rubber, whereinthe mass ratio of the liquid rubber to the hollow micro beads is (130 to 200):100. The deep sea flexible buoyancy force material provided by the embodiment of the invention belongs to an excellent elastic material; during the collision, the external impact force can be buffered; the inside structure of the material is protected from being damaged; under the condition of the density being 0.6 to 0.8g / cm<3> and the pressure being 40MPa, the 72hour water absorption rate is smaller than 1 percent; the service water depth can reach 3200 meters, and can preferably reach 3600 meters.

Description

technical field [0001] The invention relates to the technical field of buoyant materials, in particular to a deep-sea flexible buoyant material and a preparation method thereof. Background technique [0002] As we all know, the surface area of ​​the ocean is about 360 million square kilometers, accounting for about 71% of the total area of ​​the earth. Since modern times, with the gradual depletion of land resources and the continuous growth of population, people have gradually turned their attention to the wider ocean, especially the deep sea. Compared with terrestrial resources, the deep sea domain has more resources. At the same time, the deep sea field is also an important field of national defense construction. Therefore, deep-sea exploration has become a necessary subject for human beings, and the development and research of materials and devices required for deep-sea exploration is also imminent. [0003] The current mainstream deep-sea solid buoyancy material is f...
