Description
Technical field
The present invention relates to ship bottom anticorrosive paint, particularly relate to a kind of hull bottom coating use rust proof paint and preparation method thereof.
Background technology
Ship bottom anticorrosive paint, is applied to shell lightwaterline with lower portion, has the coating preventing seawater corrosion performance.Ship-bottom paint, is applied to boats and ships lightwaterline with lower portion, has the coating preventing the performance such as sea-water corrosion and marine organisms attachment.21 century is century of environmental protection.Resource-saving, economizes the energy, and pollution-free is the main development direction of world's coating.The rust-inhibiting paint protective system overwhelming majority of current domestic use is solvent based coating, and the maximum shortcoming of these coating is exactly contaminate environment, inflammable and explosive, harmful, and wastes a large amount of resources and the energy.Adopt water soluble acrylic acid antirust function emulsion, nano-functional material, rust-stabilising pigment, inhibiter and auxiliary agent preparation, not containing organic solvent, do not add mercury, lead waits the anti-corrosion paint that heavy metal content is high.The Environmental Protective Water-paint of the safe chemical industry of Guangzhou collection and South China Science & Engineering University's R & D Cooperation is accredited as China by Sinopec appraisal group and initiates, and product advanced in the world, Zuo Dun company is also at Devoting Major Efforts To Developing aqueous anticorrosion paint.With watersoluble modified acrylic acid emulsion for film forming binder, add the material formulations such as antirust slurry, rust-preventive agent, nano functional auxiliary agent and form.Do not add the heavy metal content such as chromium, lead height rust-stabilising pigment.Be applicable to weather resistance and higher outdoor metal door and window, electrical equipment, pressure pocket, bridge, traffic guardrail, petrochemical industry oil tank and the large-scale iron and steel buildings of decorative effect requirement and metal products.There is good durability (more than 4 ~ 6 years working life), anti-ultraviolet function and self-cleaning function; There is good decorative effect, fast in colour beautiful; Good rustless property, acid and alkali-resistance, salt spray resistance, weathering resistance; Aqueous, environmental protective; Stronger tack and widely suitability.
Aqueous antirust paint is with water as dispersion medium, utilizes the multiple rust-proof mechanism such as physics, chemistry, and according to chemical conversion, the principles of chemistry such as network and reaction are formulated is the best regeneration product of traditional rust-proofing primer.Being widely used in the corrosionproof protections such as various automobile, boats and ships, rack, machinofacture, freight container, railway, bridge, boiler, steel construction, petrochemical equipment, is that solvent-based paints is incomparable.The feature of environmental protection: water-miscible paint and the most essential difference of oil-base paint are choosing of solvent, water-miscible paint is the paint using water as thinner, and oil-base paint uses organic solvent, these organic solvents be generally harmful, to air have pollution and incendive solvent, and can evaporate in air when film forming and go, so-called dangers to health also just produce thus.And these objectionable impuritiess can't all be volatilized totally at short notice, such as formaldehyde, it likely needs 5 to 10 years ability to volatilize completely totally.Therefore, these organic { infringement of HotTag} solvent to human body just becomes long-term action.And aqueous woodware paint, owing to using water to replace organic solvent, so what volatilize when film forming is all water, also any injury would not be brought to human body.Therefore, water-miscible paint and the most essential difference of oil-base paint are the feature of environmental protection and the impact on HUMAN HEALTH.Quick-drying: water-miscible paint have employed water-base resin of new generation, the basis of original aqueous polyurethane paint substantially increases physical performance index.Paint surface drying only needs 10 minutes at normal temperatures, solves other defects that brand water-miscible paint surface drying is slow, repainting hours is long, substantially increases working efficiency.Not water funk be not afraid of scald do not whiten: water-miscible paint of new generation is not water funk, is not afraid of boiling hot, does not whiten, and becomes outshining othersOne branch of the tree is particularly thriving in water-miscible paint industry.Hardness is high: hardness aspect is a difficult problem for water-miscible paint manufacturing for many years always, this also result in many water-miscible paint manufacturers does not have hard floor paint or can only replace with medium-sized, there is various accident in following also causing in construction, users are inspired awe even from distance, occur knowing water-miscible paint environmental protection perfectly well but dare not situation.And more than 2H high point broken through by water-miscible paint in hardness, and fullness ratio is high, paint film is moist, especially for use in Solid Door, on furniture, the first-class solid wood material of cabinet fully can present natural texture and the textural effect of timber, even can also make the effect of the high-grade household articles distinctive " seeing that wood loses paint " that oil-base paint cannot make, these all make oil-base paint all cannot compare favourably with it.Snappiness is good: water-miscible paint product paint film has unique snappiness, can withstand wreaking havoc of solar UV, solve the fraud of the easy crackle of oil-base paint paint film.Paint film non yellowing is easily repaired: organic chemical composition contained in oil-base paint determines its physicals, and paint film xanthochromia is the fact that it cannot be changed, and time paint film more of a specified duration is thinner, even disappears.And water-miscible paint theoretically, because it is inorganic reaction, thus determine the impossible xanthochromia of its paint film; From practice, the performance of water-miscible paint non yellowing is also the conclusion that subjected to time and market baptism.The paint film of oil-base paint is hard and crisp, not easily repairs after breakage, and water-miscible paint solves this difficult problem, and repairing problem is easily settled.Transparency is high: water-based look essence is nonpoisonous and tasteless, uniform coloring, has high transparency, is about the transparency about three times of oiliness, water and oil applicable type.
Water-based antirust agent is a kind of aqueous rustproof solution, can effectively protect the material such as steel, iron, prevent from getting rusty.According to the difference that rust-proof life requires, and water is pressed certain for used in combination, and the antirust time limit can reach several days to several months, if there is certain outer packaging condition, antirust time can reach more than 1 year.Steel are in production, in storage and transport process, and as without antirust treatment, within a short period of time will produce corrosion, produce detrimentally affect to the outward appearance of finished steel and performance, and the serious steel that even can cause of corrosion are scrapped.Iron and steel gets rusty and to bring about great losses to national economy; the iron and steel that the whole world is scrapped because getting rusty every year reaches several ten million tons; China reaches 5,000 hundred million Renminbi because corroding the financial loss caused in 2000, and therefore the protection of research to ferrous materials of rust protection liquid has vital role.The water-base metal rust protection liquid great majority used in the past all contain Sodium Nitrite, nitrous acid salt form aqueous protective fluids has the obviously advantage such as inexpensive, respond well and easy to use, easy removal, therefore be widely used, but people prove that nitrite can change into carcinogens and make it use and discharge is subject to strict restriction.Due to reasons such as environmental protection, people are being devoted to the research of non-nitrous salt Environment-friendlywater-base water-base rust inhibitor always for many years, achieve larger progress.Though slushing oil rust-preventing characteristic is good, cost is high, and brings difficulty to steel product post-processed.In recent years, the research of Environment-friendlywater-base water-base rust inhibitor obtained extensive concern both domestic and external, and particularly the development of long-acting water-based rust-preventive agent has become a kind of trend.Carried out nanotechnology since 2010 also to start to be applied in aqueous rustproof technology, this opens bright prospects to undoubtedly the investigation and application of antirust technology.Scientific research personnel extracts efficiently from natural phant, low toxicity rust-preventive agent, as rice bran, mangrove bark, orange peel, Folium Aloe, pomegranate rind, reed, water lily, golden cypress, rosin etc., or utilize the byproduct of industrial or agricultural to extract rust-preventive agent, and through composite modified process, improve rustless property, can turn waste into wealth like this, realize resource and make full use of.Multi-functional Research on Water Base Antirust Agent exploitation and application gradually become trend; as oil removing, rust cleaning " two-in-one ", oil removing, rust cleaning, antirust three-in-one product are also increasing, and they are by the emulsification to oil reservoir; to infiltration and the conversion of rusty scale, play the provide protection to metal product.Research and development rust-preventing characteristic is good, and stable in properties, cheap, decreasing pollution, multiple functional, water-base metal antirust agent easy to use should be the direction of researcher effort from now on.Thanomin comprises monoethanolamine, diethanolamine and trolamine, can be mineral acid and organic acid with their composite acid.Composite generation alcohol amine salt under hydramine and sour normal temperature.Jiang Haizhen etc. synthesize and have studied water-soluble organic carboxyl acid alcohol amine salt rust-preventive agent, show that its rust-preventing characteristic is relevant with the polar group kind in molecule alkyl chain length, molecule and number, and having synthesized organic carboxyl acid alcohol amine salt rust-preventive agent ATEA-1 accordingly, its aqueous solution of 0.25% can make steel product 48h stainless.It is also a kind of effectively rust-preventive agent that monoethanolamine and diethanolamine and carboxylic acid heat the acid amides generated, very rare alkylol amide solution can prevent iron and steel from getting rusty, and there is good anti-hydrolytic performance, there is thickening power to aqueous rust preventive simultaneously, thus avoid rust-preventive agent and run off from metallic surface, and make rust-preventive agent in metallic surface firm attachment.Nitrogen-atoms in organic carboxyl acid alcohol amine salt and alkylol amide molecule and Sauerstoffatom have lone-pair electron, the metallic surface of unoccupied orbital can be had to act on iron etc. and generate complex compound film, stop oxygen, water equimolecular contacts with metallic surface.
