Nano-metal material with high electrical insulating property and preparation method of nano-metal material

Abstract

The invention discloses a nano-metal material with a strong electrical insulating property and a preparation method thereof. Titanium alloy metal particles of nanoscale particles are adsorbed on the surface of a conductive magnet, anodic oxidation is carried out, and a titanium dioxide passivation film is generated on the surfaces of the particles during anodic oxidation, so that the electron transfer rate of the surfaces of the titanium alloy metal particles is reduced, and the titanium alloy nano metal particles are made to be non-conductive; when hot isostatic pressing is carried out for forming, after inert gas is introduced for three times and heat preservation is carried out for three times, a prepared nano-metal material has large gaps, the mass is light, and the thickness is thin; liquid organic silicon modified acrylic resin is brushed on the surface layer of the formed nano-metal material, the nano-metal material is immediately put into cold water to be cooled, the outer layer of the nano-metal material is coated with the organic silicon modified acrylic resin in the mode, surface energy is reduced, marine organisms are difficult to adhere to the nano-metal material or the marine organisms is easy to fall off after adhesion, and the antifouling effect is achieved.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a nano-metal material with strong electrical insulation and a preparation method thereof. Background technique [0002] Ships sail on the ocean, and the parts in contact with seawater are not only strongly electrochemically corroded by seawater, but also fouled by marine organisms; seawater is a very strong corrosive medium for steel materials, and many marine organisms and Microorganisms can adsorb on the bottom of ships, propellers, ship pipelines and other metal structures and grow and reproduce. Especially in warm seas and in spring and summer, these harmful organisms grow and reproduce rapidly, and the pollution is particularly serious; these marine organisms and microorganisms It can destroy the anti-corrosion protective layer on the surface of the hull and cause the paint film of the hull to fall off; the adsorption on the bottom of the ship and the surface of the propeller in...

Problems solved by technology

[0002] Ships sail on the ocean, and the parts in contact with seawater are not only strongly electrochemically corroded by seawater, but also fouled by marine organisms; seawater is a very strong corrosive medium for steel materials, and many marine organisms and Microorganisms can adsorb on the bottom of ships, propellers, ship pipelines and other metal structures and grow and reproduce. Especially in warm seas and in spring and summer, these harmful organisms grow and reproduce rapidly, and the pollution is particularly serious; these marine organisms and microorganisms It can destroy the anti-corrosion protective layer on the surface of the hull and cause the paint film of the hull to fall off; the adsorption on the bottom of the ship and the surface of the propeller increases the resistance of the ship and increases the fuel consumption; the adsorption in the pipeline of the ship causes the blockage of the pipeline, and some attached organisms themselves are harmful to Metals are corrosive; seawater and microbial corrosion reduce the service life of the ship, increase the cost of maintenance and repair, and seriously endanger the safety of the ship

[0003] Metals are destroyed by marine organisms and microorganisms in seawater. Corrosion of the metal structure will lead to thinning of the material and lower strength, sometimes perforation or fracture, and even structural damage
