Embodiment 1

[0033] Preparation method of barrier explosion-proof composite material:

[0034] The aluminum alloy sheet strip with a thickness of 0.02mm is selected, and the surface is subjected to an alkali etching process. The degreasing process uses ethyl acetate as the degreasing solvent, soaking at 70 ° C for 1 min; % nitric acid solution at 20°C for 1.5min. Then, the aluminum alloy flakes are made into mesh-shaped aluminum alloy foil by cutting and stretching process, and then the functional coating is applied by spraying. Among them, the primer is coated with water-soluble E-20 epoxy ester through electrodeposition, and the thickness is controlled to be no more than 10 microns. The anti-corrosion and conductive functional coating adopts E-03 type epoxy resin with a molecular weight of 6000-8000 and 703 # The phenolic resol resin is mixed in a ratio of 7:3 (it can take into account the toughness of the macromolecular epoxy resin and the rigidity of the phenolic resin.), and add 5% ...

Embodiment 2

[0036] Choose an aluminum alloy sheet belt with a thickness of 0.02mm, and polish the surface to make the surface cleanliness not lower than Sa1 level (so that there is no visible grease or dirt on the surface, no scale, rust and Attachments such as paint coatings can significantly improve the adhesion of the resin on its surface), and the rest of the treatment process is the same as in Example 1.

Embodiment 3

[0038] The aluminum alloy sheet strip with a thickness of 0.02mm was selected, and its surface was treated by alkali etching process. The degreasing process used acetone as the degreasing solvent, the alkali treatment was 50 ° C for 1 min, and the light extraction process was 30 ° C for 0.5 min. Then, the aluminum alloy flakes are made into mesh-shaped aluminum alloy foil by cutting and stretching process, and then the functional coating is applied by spraying. Among them, the primer is coated with water-soluble E-20 epoxy ester by electrodeposition, and the thickness is controlled not to exceed 10 microns; the anti-corrosion and conductive functional coating is made of epoxy-polyurethane acrylate mixed with 10% carbon nanotubes as a conductive agent After heating at 120°C for 2 minutes, it is cured by ultraviolet radiation. When the curing degree of the primer is 50%, the mixed anti-corrosion conductive paint is evenly sprayed on the surface of the primer, and the thickness is...

Abstract

The invention discloses an obstructive explosionproof composite and a preparation method thereof. Honeycomb aluminum foil or honeycomb paper foil is used as a structural base material, and after the surface of the structural base material is coated with a coating having corrosion prevention and electric conduction function, the problems that existing metal obstructive explosionproof materials areeasy to corrode and short in use life, and cannot be used in dynamic fuel storage vessels are solved. When the honeycomb paper foil is used as the structural base material, production cost of an existing obstructive explosionproof material system can be substantially reduced, and the obtained obstructive explosionproof composite is suitably applied to large oil material storage vessels, and simultaneously the preparation method of the obstructive explosionproof composite facilitates large area popularization and usage of the obstructive explosionproof composite.

Description

technical field [0001] The invention belongs to the field of barrier and explosion-proof oil and gas tanks, and in particular relates to a barrier and explosion-proof composite material and a preparation method. Background technique [0002] In the existing technology, the domestic barrier explosion-proof technology is applied in the market, such as buried storage tanks in gas stations, barrier explosion-proof skid-mounted refueling device oil storage tanks, flammable liquid storage tanks in chemical plants, oil tanker storage tanks, automobile fuel tanks, The barrier explosion-proof materials used in liquefied petroleum gas storage tanks mainly include the following three types: mesh aluminum alloy barrier explosion-proof materials, mesh polyurethane foam explosion-proof materials, spherical non-metallic barrier explosion-proof materials, etc. [0003] BLEVE (Boiling Liquid Expanding Vapour Explosion), that is, when a high-pressure storage tank encounters a fire, trapped ai...
