Description
Technical field
The invention belongs to anticorrosive paint technical fields, and in particular to a kind of being free of based on modified polyaspartic ester
Solvent anticorrosive paint and preparation method thereof.
Background technique
With the fast development of economic construction of China and national economy, various steel constructions, concrete structure, plastic-aluminum structure etc.
It is more and more applied in the industry such as bridge, building, harbour, traffic and civil engineering, but it easily corrodes (corrosion)
Feature brings huge economic losses to equipment manufacture, and damages natural resources and enviroment protection.One statistics display, corrosion
Loss accounts for the 3-5% of GDP, is more than that summation is lost brought by the disasters such as fire, floods, drought and typhoon, and 2010, China
Corrosion loss be at least 1.2 trillion yuans, and if taking effective corrosion protection steps, wherein the loss of 25-40% be can
To avoid.Therefore, anti-corrosion is particularly important, and in various anticorrosion techniques, coating plays various engineering products and facility
To good protective effect, a series of anticorrosion coating is developed in succession both at home and abroad.
Anticorrosive paint is generally divided into conventional anticorrosive paint and anticorrosive paint, is essential a kind of painting in paint
Material.Conventional anticorrosive paint is under general condition, to play the role of the longevity etch-proof, protection non-ferrous metal uses to metal etc.
Life；For anticorrosive paint refers to relatively conventional anticorrosive paint, can be applied in relatively harsh corrosive environment, as ship, bridge,
The steel materials such as harbour, and there is a kind of anticorrosive paint that can reach the protection period longer than conventional anticorrosive paint.
Currently, domestic common anticorrosive paint system has epoxy coating, polyurethane resin coating, glass flake to apply
Material etc..Epoxy resin possesses good filming performance and higher adhesive force, but epoxy resin is not ageing-resistant, Yi Fenhua, high temperature
Lower receiving strong corrosive medium ability is poor；Polyurethane resin coating adhesive force is excellent, mechanical property is good, resistance to chemical corrosion is good, but
Workability and poor storage stability, paint film is easy blistering, in addition, raw material isocyanide used in polyurethane coating production process
Acid esters has very big toxicity to people；Glass-flake coating theoretically have excellent chemical corrosion resistance, waterproof, vapor,
Corrosive ion, temperature resistance energy, but such coating is for the thickness of scale, the arrangement mode of scale, scale and film forming matter
Bonding force have very high requirement.
Polyaspartic Ester-Based Coatings are a kind of novel aliphatics occurred in recent years in polyurea industry field, slow anti-
It answers, high-performance coating, referred to as third generation polyureas.Polyaspartic ester resin is a kind of secondary aliphatic amine, it most earlier than
Nineteen ninety can be used as the response type solvent of solvent borne polyurethane coating by Zwiener et al. discovery, can contain hydroxyl with common
The polyester of base, polyacrylate copolymer is miscible, to reduce the VOC content in coating system.Polyurea Spraying is a kind of
The green spraying technology of novel solvent-free, high response.The technology outstanding feature is environment friendly and pollution-free, it can be achieved that rapid curing.
But since reaction speed is too fast, construction needs special high temperature and pressure impacting type mixed spraying equipment；Not to the wetability of substrate
It is good, poor adhesive force；Coating surface point easy to form, tangerine peel etc., apparent state difference；Exothermic heat of reaction is concentrated, and shrinking percentage is big.
CN103820013A discloses a kind of heavy antisepsis spray polyurea coating, and component A is made of isocyanates and polyalcohol,
B component is made of liquid polysulphide rubber, amine chainextender, pigments and fillers and auxiliary agent.The Paint preparation technology is complicated, and Special spray coating is needed to set
Standby construction.
CN102993929A discloses a kind of epoxy-modified spray polyurea anticorrosive paint for steel structure surface, component A
It is that semi-prepolymer obtained is reacted by polyisocyanates, polyether polyol, epoxy resin and a small amount of diluent, B component is by end ammonia
Base polyethers, amine chainextender, filler and auxiliary agent composition.The invention coating utilizes epoxy resin modification polyureas, is set using Special spray coating
Standby construction, hardness of paint film are larger.
CN103113813A discloses a kind of anti-aging high molecular nanometer modified coating material of Hydraulic Steel-structure anti-corrosion.Substrate
After blasting treatment, the priming paint of 2 powders containing polytetrafluorethylenano nano is brushed, then sprayed with special equipment and received containing polytetrafluoroethylene (PTFE)
The nano modification polyurea coating of rice flour body.The polyureas component A is made of diisocyanate and polyether-tribasic alcohol, and B component is by end ammonia
Base polyethers, aniline and the polytetrafluorethylenano nano powder composition for accounting for coating quality 1-3%.Modified coating antiseptic performance improves,
But preparation process is more complex, requires spraying equipment high.Bi-layer coating structure keeps spraying process complicated, and construction efficiency is low.
NH1420 and NH1520 resin of traditional polyaspartic ester resin just like Bayer, NH1420 and HDI trimerization
When precursor reactant, operable time is short, poor to the adhesive force of substrate.When NH1520 is reacted with HDI trimer, although the operating time
It is long, but the adhesive force of substrate is lost substantially at 10 DEG C hereinafter, coating starts to become fragile.It is therefore desirable to place is modified to it
Reason is to improve performance.
Currently, being much modified in the market using Flexible Curing Agent to polyaspartic ester resin, when making its operation
Between long, good toughness.Solvent-free Flexible Curing Agent viscosity is big, and normal construction difficulty is big, if the diluents such as addition organic solvent can drop
Low viscosity, but the addition of organic solvent, VOC (volatile organic compounds) content improves, compared with traditional anticorrosive paint,
It is no longer belong to the scope of solventless coatings.Attention with various countries' environmental regulation to the limitation of VOC and to environmental protection, no-solvent type
Coating substitution has coatings volatile organic compounds that will gradually become an important developing direction.
In summary, it is necessary to develop a kind of with good toughness, excellent in cushion effect, coating compactness height, corrosion resistant
Corrosion can be good, the solvent-free anticorrosive paint that quality is stable, cost is controllable, easy for construction and environmental-friendly.
