Description
Technical Field
The invention relates to the technical field of coatings, in particular to a solvent-free heavy-duty anticorrosive coating.
Background
The rapid development of modern marine industries, such as marine equipment manufacturing, high-technology ships, "offshore barns", national marine ranches, marine environment monitoring and detection, marine biomedicine and biological products, seawater desalination, aquatic product transaction, cold chain logistics, etc., is based on the foundation of marine equipment facilities such as concrete and steel structures, and the corrosion of materials caused by the harsh natural environment of much water and high salt is a key technical problem which must be solved, and the corrosion of marine engineering materials causes hundreds of billions of yuan of economic loss according to incomplete statistics.
The coating material is the simplest and most effective marine corrosion and protection technology with the application rate of more than 80 percent, but almost all products are solvent-based coatings. The organic solvent content in the product is large and generally reaches about 40 percent (mass ratio) of the formula amount. The organic solvents are volatilized after construction, which causes resource waste, environmental pollution and fire hazard. The problem of using organic solvents is rapidly solved, and the problem is a serious problem in the field of coating materials.
The impact of the spray can destroy the protective layer strongly due to the alternation of dry and wet in the sea splash zone and the tidal range zone, so that the corrosion is accelerated, and the facilities of the sea equipment are easy to damage. Once the coating is damaged, the repair construction environment is very bad, and the construction requirements are also very strict: the construction time is not longer than 24h (including substrate treatment, coating and curing), so that the requirements on the technical performance and the construction performance of the coating are extremely high, and the requirements on at least the following aspects are met: adhesion on low-treated surfaces: wet, rusty and greasy dirt (the splash zone is seriously polluted by oil); quick curing: the surface dryness is less than 2h, and the actual dryness is less than 24 h; long-term corrosion resistance.
Because the currently applied marine steel structure coating materials are mostly solvent type, such as chlorinated polyethylene, solvent type epoxy, solvent type polyurethane and the like, the marine and environmental pollution caused by the above varieties is huge, and meanwhile, the constructability in marine environment (particularly in a splash zone) is poor, and the coating protection period is short, therefore, a set of long-acting environment-friendly marine splash zone steel structure heavy-duty anticorrosive coating material and coating technology are urgently needed for repairing and coating requirements in marine facilities and engineering equipment tidal range zone and splash zone water environment, so as to realize water-borne coating and improve the construction timeliness.

In order to solve the second technical problem, the technical solution of the present invention is:

As a preferable technical scheme, the stirring speed of the high-speed stirring is 600-1200 r/min; the fineness after grinding and dispersing is less than 100 mu m.
Due to the adoption of the technical scheme, the invention has the beneficial effects that:
the solvent-free heavy-duty anticorrosive paint capable of being coated with water and rust does not use an organic solvent, reduces the viscosity of a system and participates in a crosslinking reaction by diluting epoxy resin with a toughening modifier with active epoxy functional groups to form a part of a coating film, and does not become VOC (volatile organic compound) or diffuse in water; the catalytic action of phenolic hydroxyl in the curing agent improves the reaction rate, the fluorine-containing silicone resin with low surface energy improves the wet film infiltration and the dry film hydrophobicity, the inorganic gelled material can generate hydrate when contacting with water, the hydrate is quickly solidified and formed, the interface moisture is replaced, the mechanical property of the coating is enhanced while the quick curing is promoted, the synergistic action of the rust converting agent and the rust stabilizer is integrated, the rust on the substrate is converted into stable harmless substances to be present in the paint film, so that the rust is firmly attached to the steel structure, and the effects of sealing and passivating the rust are achieved; the lamellar anti-corrosion filler film forms a fish scale arrangement structure, has strong anti-permeability, and can prevent and delay water, oxygen and other corrosion media from entering the coating to further slow down the erosion of the substrate. The low surface energy fluorine-containing silicone resin and the nano silicon dioxide material have the low surface energy anti-fouling effect, so that the attachment and erosion of fouling and marine life to the surface of the coating can be delayed. Therefore, the anticorrosive paint is a novel composite filler system integrating the functions of rust stabilization, rust conversion, sterilization, shielding, corrosion prevention and the like, and can be quickly cured in water to form an organic crosslinking-inorganic gelling film-forming system with low surface tension and reaction with water. Through the synergistic effects of interface water displacement, rust chelating conversion, zinc oxide contact sterilization and the like, the technical problems of difficult volatilization of a solvent in water, residual moisture of a wet film, slow low-temperature curing reaction rate, poor wettability on the surface of a base material, poor hydrophobicity of a coating, poor adhesion of a coating film caused by surface treatment residues and continuous corrosion are solved. The coating material system of the invention forms a coating film structure which takes an organic cross-linked body as a continuous phase and an inorganic gel body as an island dispersed phase after being cured, the touch dry time in seawater at 10 ℃ is reduced to 30min, the hardness is up to 4H after being cured for 7d in the water, the impact strength is improved to 50cm "kg, and the fast curing film forming in the seawater environment is realized. Solves the problems that the surface treatment of the substrate in seawater is difficult and the secondary coating is affected by a large amount of residues such as rust, coating materials, microorganisms and the like after the treatment in the prior art.
The inorganic cementing material can generate hydrate when contacting with water, is quickly solidified and formed, replaces interface moisture, can promote the curing effect, simultaneously enhances the mechanical property of a coating, and realizes the characteristics of coating the water-containing bottom material and coating the underwater to form a film.
The zinc oxide in the anti-rust pigment can be used for cooperating with other anti-rust pigments for rust prevention, and can prevent microorganisms in water from attaching and damaging a paint film and prolong the service life of the coating due to the astringency and certain sterilization capability.
The cashew nut shell oil modified phenolic aldehyde amine curing agent in the curing agent disclosed by the invention contains aliphatic diamine terminal groups, weak acidic phenolic hydroxyl groups and unsaturated bis (diamine-phenol) groupsC15 straight chain of bonds. The weak acidic phenolic hydroxyl can catalyze the low-temperature rapid curing of the aliphatic diamine terminal group and the epoxy group. The C15 straight-chain substituent on the benzene ring reduces the surface energy and surface tension of the epoxy resin system, thereby improving the fluidity and adhesion of the epoxy resin coating on the coating surface. The long carbon chain and benzene ring structure can obviously improve the water resistance and corrosion resistance of an epoxy resin system, the unsaturated double bond on the long carbon chain reduces the viscosity of the curing agent, and improves the fluidity of the molecular chain at low temperature, thereby improving the low-temperature curing speed. Nano Si 0 2 In the process of curing the coating, a silica structure is formed, so that the silica structure has hydrophobicity, can inhibit the flowing of the coating, quickens the curing speed, improves the bonding strength and increases the sealing property and the seepage resistance of the coating.
The solvent-free heavy anti-corrosive paint capable of being coated with water and rust can be normally coated according to a normal water-free environment, and can also realize underwater coating, after attachments (surface marine organisms, rust, old paint films and the like) on a coated substrate are removed, a prepared coating material is uniformly coated on lining cloth such as a glass fiber bandage, canvas, polyethylene film and the like in a scraping way, the substrate is coated underwater, water and air bubbles are discharged by extrusion, and the coating is cured and formed, so that the coating is more uniform, and the construction efficiency is higher; and (3) for irregular surfaces, adopting a roller coating or troweling mode, and using the extrusion action of a roller or a scraper to drain water on the surfaces, so that the coating is attached to the surface of a steel structure and is cured into a film. The invention has excellent quick-drying performance and rust conversion and stabilization performance, even can realize underwater rusty coating, and can also obtain good corrosion resistance and durability. Compared with the traditional underwater blade coating process, the surface of the coating material is flat and uniform, the construction efficiency is improved by 3 times, and the effects of reducing the cost and reducing the environmental pollution are achieved. The method overcomes the influence of tidal cycle on repair coating, realizes all-weather high-efficiency, safe and environment-friendly construction, effectively solves the problems of difficult surface treatment, substrate surface moisture, alternate wetting and drying, underwater construction and the like in the failure repair of the coating of the marine engineering equipment facility, provides technical support for the construction and equipment manufacture of the marine engineering facility, and promotes the green and healthy development of modern oceans.
