Problems solved by technology

However, anti-mildew coatings on the market cannot inhibit the growth of these microorganisms
[0005] Second, the static electricity generated during fuel transportation and use, and the flammable mixed gas formed by the volatilized oil and gas of jet fuel and air can easily cause combustion and explosion accidents
And be used for the anti-mildew type conductive coating of metal oil tank and have not yet seen the report

Abstract

The invention discloses a metal oil tank mould-proof conductive electrostatic anticorrosive coating which comprises a component A and a component B, wherein the component A comprises modified epoxy resin, a solvent, a dispersing agent, a conductive material and a functional filler; and the component B is a composite epoxy curing agent prepared from polyamide resin, a modified amine curing agent and n-butyl alcohol. The metal oil tank mould-proof conductive electrostatic anticorrosive coating is characterized in that the component A comprises a mildew preventive and zinc oxide whiskers; and the conductive material is conductive mica powder. Before use, the component A and the component B are mixed according to a weight ratio of 20:1-1.5. The multiple experiments prove that the coating has excellent mildew resistance, has excellent mold resistance on the specific strains of aircraft fuel, meets the static conductive requirements of light fuel oil, can be widely applied to inner walls of oil tanks, vehicles and oil pipelines and is environment-friendly on the oil.

Description

Technical field: [0001] The invention relates to an anti-static anti-corrosion paint with anti-mildew effect for the inner wall of a metal oil tank. Background technique [0002] The potential safety hazards in the fuel storage process in metal oil tanks are mainly manifested in two aspects: [0003] One is that the microorganisms in the fuel oil not only affect the storage quality of the oil, but also cause serious corrosion on the inner wall of the oil tank and the oil pipeline. In addition, microbial clusters may block the filter system of the aircraft, which will bring major hidden dangers to flight safety. [0004] In addition to strengthening the management of oil products and ensuring the cleanliness of oil products, the existing microbial control measures are mainly to inject bactericides into the oil products, which have incomplete bactericidal effects and poor stability. Although there are anti-mildew paints on the market, the purpose is to prevent mildew and ste...
