At present, the common method for the anticorrosion treatment of metal is to coat a layer of coating on the surface of the metal to isolate the surface of the metal from the external corrosive medium, and the main principle of the anticorrosion by using the coating is to isolate the medium from the substrate.
However, the coatings used in the prior art typically have voids. One of the pores is a structural pore whose size is related to the molecular structure of the coating film-forming material, typically 10-5To 10-7The range of cm; another type of pore is a pinhole formed by volatilization of the solution during the coating process, and the pore is large and is about 10-2To 10-4cm range. Since the diameter of the medium (e.g., small molecules such as water, acids, bases, etc.) is generally smaller than the structural porosity of the coating, these media can easily pass through the coating film, causing structural corrosion.

In addition, the labyrinth effect of the modified flake aggregate (such as the modified basalt flake) in the coating can also effectively reduce the corrosion speed of a corrosion medium; the nano particles can be filled in the gaps or the capillary holes of the coating, so that the anti-permeability of the coating can be further improved, and the coating has a strong shielding effect.
Detailed Description
In order to make the technical solution and advantages of the present invention more apparent, the present invention is described in further detail with reference to the following embodiments.
The embodiment of the invention provides a nano modified epoxy heavy-duty anticorrosive paint which comprises the following components in parts by mass (8-10): 1 a component and a b component;
the component A comprises the following raw materials in parts by mass:
35-50 parts of epoxy resin, 2-10 parts of modified nano material, 5-20 parts of modified flake aggregate, 6-10 parts of mixed solvent, 5-15 parts of silane coupling agent, 2-8 parts of antirust agent, 1-5 parts of auxiliary agent, 5-10 parts of filler and 3-12 parts of pigment;
the component B comprises the following raw materials in parts by mass:
15-30 parts of polyamide epoxy curing agent, 10-15 parts of cashew nut oil modified epoxy curing agent and 35-50 parts of mixed solvent.
In the technical scheme of the invention, the epoxy resin coating has high mechanical strength and cohesive force, particularly strong adhesive force to metal, good chemical resistance and oil resistance, particularly good acid and alkali resistance, and the like, and is easy to process and modify. However, epoxy resins can also be modified in general due to their brittle nature.
Additionally, by way of example, in a preferred embodiment of the present invention, the epoxy resin may be a bisphenol a epoxy resin.
In addition, the nano-scale particles have obvious improvement effect on various performances of the epoxy resin. The nano-scale particles have strong bonding effect with a matrix interface, the coating is favorable for stress transfer when stressed due to the small-size effect of the nano-scale particles, and the coating has extremely strong activity due to the serious insufficient coordination on the surface of the nano-material, so that the cross-linking reaction of epoxy resin can be further promoted, the intermolecular bonding force is improved, and meanwhile, the coating becomes more compact and the wear resistance is also greatly improved. In addition, the micron particles have larger particle size and can block the movement of a high molecular chain segment in the composite coating, so that the impact resistance of the coating is influenced, and the epoxy group and the nano particles on the interface generate a force far greater than the action force of Van der Waals force, so that a very ideal interface is formed, and the functions of well initiating microcracks and absorbing energy can be achieved. Therefore, the organic coating anticorrosive material is modified by utilizing the nanotechnology, so that the comprehensive performance of the organic coating anticorrosive material can be effectively improved, particularly the mechanical strength, hardness and adhesive force of the material are increased, and the light resistance, aging resistance, weather resistance and the like are improved.
In addition, as an example, in a preferred embodiment of the present invention, the modified nanomaterial may include: nano silicon dioxide and nano aluminum oxide; the mass ratio of the nano silicon dioxide to the nano aluminum oxide is 1: 1.
Nano SiO2The particles have a three-dimensional network structure, and due to the characteristics of serious coordination deficiency on the surface, huge specific surface area, surface oxygen deficiency and the like, the particles show extremely strong activity, are easy to combine with oxygen of epoxy cyclic molecules, improve the bonding force among the molecules, and greatly improve the strength, toughness, ductility, corrosion resistance and other properties of the epoxy resin coating. Nano Al2O3Also contains a three-dimensional cross-linked network and has the advantages of high hardness, high strength, good thermal stability, wear resistance, corrosion resistance and the like. Therefore, after the nano particles are added into the epoxy resin coating, the nano particles can be bonded with functional groups of epoxy by secondary chemical bonds, and the film-forming substance and the nano particles are reinforcedThe binding force of the filler reduces the capillary action of the coating to improve the shielding performance of the coating, thereby increasing the hardness and impact resistance of the coating and improving the scratch resistance and impact resistance of the coating.
In addition, in the technical scheme of the invention, the scale refers to a thin slice with certain particle size and thickness formed after metal and certain inorganic compounds are treated by a physical or chemical method. Common scales are: glass flakes, mica iron oxide flakes, graphite flakes, zinc-aluminum alloy flakes, stainless steel flakes, and basalt flakes. The scale aggregate, the high-performance corrosion-resistant resin and the corresponding auxiliary agent are added into the anticorrosive paint, so that various heavy anticorrosive paints can be prepared. The scale coating is of a multilayer sheet structure, can form a parallel superposed staggered thick film to generate a special labyrinth effect, not only can divide the coating into a plurality of small spaces to reduce the shrinkage stress and the expansion coefficient of the coating, but also can force the medium to roundly infiltrate, thereby delaying the route and the time of the corrosion medium diffusing and invading the matrix, having excellent permeability resistance, impact resistance, wear resistance and corrosion resistance, and effectively prolonging the service life of the coating.
In addition, the basalt has wide sources and low cost, and belongs to a resource-saving, green and environment-friendly material. Wherein, the basalt flakes have excellent medium penetration resistance. Thus, the addition of modified basalt flakes to the coating can create a special "labyrinth effect". The binding strength of the basalt scales with metal and concrete is high, the working temperature range is 200 ℃ below zero at the lowest, and can reach 1000 ℃ at the highest, and the basalt scales can adapt to working environments with large temperature difference and poor environmental conditions. In addition, compared with the glass flakes, the basalt flakes have high contents of iron oxide, titanium dioxide, aluminum oxide and calcium oxide, which are respectively 15.0%, 1.4%, 16.0% and 9.5%, and the basalt flakes have relatively few alkali oxides, such as 50% of silicon dioxide; the glass flakes do not contain iron oxide and titanium oxide, the content of aluminum oxide is 2%, the content of calcium oxide is 7%, and the content of silicon dioxide exceeds 50%. Therefore, the basalt flakes have better acid and alkali resistance, weather resistance and wear resistance than glass flakes, and can well make up for the defects that the epoxy coating has insufficient hardness and toughness and is easy to crack under the action of thermal stress or impact.
Thus, by way of example, in one preferred embodiment of the invention, the modified flake aggregate may be a modified basalt flake.
In addition, as an example, in a preferred embodiment of the present invention, the modified basalt flakes have a mesh size of 200 to 500 mesh and a thickness of 1 to 3 μm.
Although the nano material and the scale are different in size grade, both can increase the strength and the compactness of the coating and enhance the shielding effect of the coating. Therefore, in the technical scheme of the invention, aiming at the improvement effect of the scales and the nano materials on the coating structure on different scales, the modified nano materials and the modified basalt scales are simultaneously doped into the epoxy resin, so that the compactness of the coating material can be effectively improved, the corrosion resistance of the coating is enhanced, and the durability of the coating is improved.
In addition, as an example, in a preferred embodiment of the present invention, the mixed solvent in the component a may be an epoxy paint thinner; the epoxy paint thinner may include: butanol and xylene, wherein the mass ratio of the butanol to the xylene is 3: 7.
In addition, as an example, in a preferred embodiment of the present invention, the silane coupling agent may be any one of γ -aminopropyltriethoxysilane, γ - (2, 3-glycidoxy) propyltrimethoxysilane, or γ - (methacryloyloxy) propyltrimethoxysilane.
In addition, as an example, in a preferred embodiment of the present invention, the rust inhibitor may be one or more of phthalate, aluminum tripolyphosphate, or zinc tripolyphosphate.
Further, by way of example, in a preferred embodiment of the present invention, the adjuvant may be a mixture of 904S wetting dispersant and 606 defoamer; wherein the mass ratio of the dispersing agent to the defoaming agent is 5: 4.
in addition, as an example, in a preferred embodiment of the present invention, the filler may be a mixture of 1250 mesh talc and calcium carbonate; the weight ratio of 1250-mesh talcum powder to calcium carbonate is 8: 6.
In addition, as an example, in a preferred embodiment of the present invention, the pigment may be any one of rutile type titanium dioxide, red iron oxide, carbon black, phthalocyanine blue, phthalocyanine green, or mica iron dust.
In addition, as an example, in a preferred embodiment of the present invention, the mixed solvent in the component b may include: the xylene and the butanol are mixed according to the mass ratio of (1-3): 2.
further, by way of example, in a preferred embodiment of the present invention, the polyamide epoxy curing agent may be 650 polyamide epoxy curing agent.
Additionally, by way of example, in a preferred embodiment of the present invention, the cashew oil-modified epoxy curing agent can be 8235 cashew oil-modified epoxy curing agent.
In addition, in the technical scheme of the invention, the scale aggregate (such as basalt scale) and the nano material are both inorganic material fillers, have hydrophilic and oleophobic properties, are not enough in binding force in the organic coating, are difficult to uniformly disperse in an organic medium, easily cause section defects, and reduce the overall performance of the coating. For the nano material, even if the nano particles are dispersed in the coating by adopting a high-speed stirring method, the agglomeration phenomenon is still difficult to avoid. Therefore, before the scale aggregates (such as basalt scales) and the nano materials are stirred and mixed with other materials, the surfaces of the nano materials and the scale aggregates can be modified to obtain modified nano materials and modified scale aggregates.
Since the silane coupling agent has both a reactive group capable of chemically bonding to an organic material (e.g., a synthetic resin) and a reactive group capable of chemically bonding to an inorganic material (e.g., glass, silica sand, etc.) in the molecular formula, in the technical scheme of the present invention, the scale aggregate (e.g., basalt scale) and the nanomaterial may be subjected to a surface modification treatment using the silane coupling agent, so that the phenomenon of uneven dispersion of the nanomaterial and the scale aggregate in the coating material may be well improved.
Therefore, in the preparation method of the nano modified epoxy heavy-duty anticorrosive paint, the epoxy resin can be used as a matrix, the two-component paint is adopted, firstly, the scale aggregate (such as basalt scale), the nano material and the silane coupling agent are mixed together, and the scale aggregate and the nano material are subjected to modification treatment to obtain the modified scale aggregate and the modified nano material; mixing epoxy resin, a modified nano material, an antirust agent, an auxiliary agent, a pigment, a filler and modified flake aggregate in a mixed solvent to prepare a component A, and mixing a polyamide epoxy curing agent and a cashew nut oil modified epoxy curing agent in the mixed solvent to obtain a component B; and finally, mixing the component A and the component B according to the ratio of (8-10): 1, and fully stirring the mixture uniformly to obtain the nano modified epoxy heavy-duty anticorrosive paint.
In summary, in the technical scheme of the present invention, the nano modified epoxy heavy anti-corrosion coating is prepared from the micron-sized and millimeter-sized modified scale aggregates (e.g., modified basalt scales), the modified nano material and the epoxy resin according to a certain ratio, so that a continuous and compact coating can be formed, the coating can be in close contact with a metal substrate, the bonding force between the modified nano particles and the epoxy base material in the coating is strong, a compact nano network structure can be formed, and the penetration of corrosive media can be effectively resisted. In addition, the labyrinth effect of the modified flake aggregate (such as the modified basalt flake) in the coating can also effectively reduce the corrosion speed of a corrosion medium; the nano particles can be filled in the gaps or the capillary holes of the coating, so that the anti-permeability of the coating can be further improved, and the coating has a strong shielding effect.
Therefore, the nano modified epoxy heavy-duty anticorrosive coating provided by the invention has excellent corrosion resistance, and can be widely applied to the steel structure corrosion prevention fields of ocean engineering, petrochemical industry, metallurgical mining and the like.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
