Deep-sea solid buoyancy material and manufacture method thereof

Abstract

The invention discloses a deep-sea solid buoyancy material and a manufacture method thereof. The deep-sea solid buoyancy material is characterized by including the following raw materials in parts by weight: 100 parts of epoxy resin, 0-20 parts of a toughening modified agent, 10-80 parts of a curing agent, 0.5-5 parts of a catalyst, 0.2-10 parts of a dispersing agent, 20-300 parts of hollow glass beads, 0-10 parts of chipped fibers and 0.2-5 parts of a coupling agent. Based on the contradiction between the pressure-bearing performance and density of the solid buoyancy material, a method of mixing the hollow glass beads with bigger density and higher pressure-bearing performance with the hollow glass beads with lower density and poorer pressure-bearing performance and appropriately adding the chipped fibers and / or aramid fibers used as reinforcing materials of the solid buoyancy material to prepare the solid buoyancy material is provided; the deep-sea solid buoyancy material formed through adopting the method is low in water absorption, has the density lower than 0.73 g / cm <3>, bears pressure higher than 110 MPa, and meets a requirement for the application in full deep sea areas.

Description

technical field

[0001] The invention belongs to the technical field of solid buoyancy material for marine environment, and relates to a solid buoyancy material for deep sea and a manufacturing method thereof. Background technique

[0002] With the rapid development of economy and the continuous increase of population in all countries in the world, human beings consume more and more natural resources, and land and offshore resources are decreasing day by day. At the same time, people have turned more attention to the ocean, especially the deep sea. In the depths of the seabed at a depth of 4000-6000 m in various oceans in the world, there are widely distributed oceanic polymetallic nodules containing more than 70 elements such as manganese, copper, cobalt, nickel, iron, etc., as well as cobalt-rich crust resources, hydrothermal sulfides, etc. Rich resources such as natural gas hydrate and deep-sea biological gene resources have good prospects for scientific research and comm...
