Description
Technical Field
The application relates to the field of epoxy resin coatings, in particular to an epoxy composite coating containing dopamine modified fibers, and a preparation method and a construction process thereof.
Background
The complexity of the marine environment causes the problems of serious corrosion and erosive wear failure of a basic form of marine engineering, namely a steel pipe pile in the service process; mainly because of the continuous damage effect of coupling of multiple factors such as periodic dry-wet alternation state, saturated oxygen, sunlight, humid sea wind, spray scouring and sediment erosion in a spray splashing area; therefore, the development of the protective coating of the steel pipe pile with long service life and high reliability has important economic value and social significance for ensuring the safe and durable operation of the ocean major engineering facilities.
In the related technology, the protection measures for steel pipe piles at home and abroad are as follows: metal thermal spray coatings, protective jackets, electrochemical protection, and organic coatings, among others. Wherein, the electrochemical protection is suitable for the sea mud area and has little effect on the spray splashing area; the alloy thermal spraying coating has good corrosion resistance, but does not resist seawater erosion, and simultaneously needs special thermal spraying equipment, has high construction requirement and high price; the protective technology of petrolatum coating is developed in oceans, the protective effect on the spray splashing area is obvious, but the working procedure is complex, the coating layer needs to be replaced, the price is high, and the maintenance is difficult; the effective organic coating protection method carried out on land can not meet the requirement of long-life safety protection under the harsh marine environment.
Disclosure of Invention
In order to solve the problems that the protective layer is not corrosion-resistant in the ocean and is short in service life, the application provides the dopamine modified fiber-containing epoxy composite coating and the preparation method and the construction process thereof.
In a first aspect, the application provides an epoxy composite coating containing dopamine modified fiber, which adopts the following technical scheme:
the epoxy composite coating containing the dopamine modified fiber is prepared from the following raw materials in parts by weight: 60-120 parts of epoxy resin coating, 20-30 parts of chemical fiber, 20-40 parts of dopamine, 3-5 parts of boron nitride, 4-6 parts of mixed preservative, 5-10 parts of copper sulfate aqueous solution, 2-4 parts of hydrogen peroxide aqueous solution, 3-5 parts of emulsifier and 30-50 parts of water.
By adopting the technical scheme, the dopamine modified fiber aims at coating a layer of dopamine on the surface of the chemical fiber, the dopamine enhances the external surface area of the traditional chemical fiber, and the dopamine has stronger bonding capacity with the epoxy resin compared with the traditional chemical fiber, so that the modified chemical fiber has stronger bonding stability with the epoxy resin coating while enhancing the crack resistance of the epoxy resin coating.
However, the dopamine is a hydrophilic substance, so that the possibility that water exists in dopamine gaps for a long time is high, and the boron nitride is added in the scheme, is of a two-dimensional nano lamellar structure, and can be used for constructing a labyrinth structure in a coating coated by the coating, so that the diffusion path of a corrosion medium in the coating is prolonged, and an excellent corrosion protection effect is obtained.
If there is the hydrone still to cross coating through the space, contacts with the steel-pipe pile, produces rust, then mixed anticorrosive in this scheme can take place the complex reaction with iron ion, produces the complex, covers on the rust surface, forms isolation space, mixed anticorrosive ability and Cu 2+ 、Be 2+ 、Mg 2+ 、Ca 2+ 、Sr 2+ 、Ba 2+ 、Zn 2+ 、Cd 2+ 、Al 3+ 、Ga 3+ 、Cr 3+ 、Mn 2+ 、Fe 3+ 、Co 2+ 、Ni 2+ 、Pd 2+ 、Ce 3+ And the complex formed by complexing various metal ions can repair the damaged coating, so that the self-repairing effect is achieved, and the service life of the coating is prolonged.
Optionally, the mixed preservative comprises sodium dichromate and 8-hydroxyquinoline.
By adopting the technical scheme, sodium dichromate is an inorganic metal corrosion inhibitor, 8-hydroxyquinoline is an organic metal corrosion inhibitor, and the sodium dichromate has the function of reacting with metal ions in the metal surface anode area to generate an oxide or hydroxide oxide film which covers the anode to form a protective film, so that the metal is inhibited from dissolving into water, the anode reaction is controlled, and the anode is passivated; the 8-hydroxyquinoline molecule has two polar groups with opposite properties, can be adsorbed on a clean metal surface to form a monomolecular film, can form a film on an anode and also can form a film on a cathode, prevents water and dissolved oxygen in water from diffusing to the metal surface, and plays a role in corrosion inhibition; in the scheme, the sodium dichromate is combined with the 8-hydroxyquinoline to obtain the mixed preservative, so that the corrosion prevention effect of the coating is further enhanced, and the corrosion prevention time of the coating is prolonged.
Optionally, the mass ratio of the sodium dichromate to the 8-hydroxyquinoline is 1: (3-5).
By adopting the technical scheme, the sodium dichromate and the 8-hydroxyquinoline in a specific ratio are used, so that the corrosion prevention effect of the sodium dichromate and the 8-hydroxyquinoline in compounding is better, the corrosion prevention life of the mixed preservative is longer, and the finally prepared epoxy composite coating is good in corrosion prevention effect and long in corrosion prevention life.
Optionally, the chemical fiber is an aramid fiber.
By adopting the technical scheme, because the aramid fiber is provided with the amide group, the dopamine carries hydroxyl, amino and phenolic hydroxyl, part of the dopamine is adhered to the aramid fiber through physical action, and part of the dopamine is connected with the aramid fiber through chemical action, the stability of the connection of the dopamine and the aramid fiber is higher, the adhesive strength of the aramid fiber and the epoxy resin coating can be improved for a long time, so that the aramid fiber can play a role in cracking resistance and toughening on the epoxy resin coating for a long time, and the service life of the coating is prolonged.
Optionally, the aramid fiber is one or more of a fully para-aramid fiber or a fully para-aramid co-polymer fiber.
