Description
Technical field
The present invention relates to steel surface coating, particularly relate to a kind of iron and steel antirust, anti-corrosive finish paint and preparation method thereof.
Background technology
Antirusting paint can protect metal surfaces from chemistry or the coating of electrochemical corrosion of air, sea propylene glycol etc..Coat antirusting paint in metal surface and can effectively avoid the direct invasion of various corrosive substances in air so that maximized prolongation metal useful life.Physical property and the big class of chemically antirust paint two can be divided into.The former is by pigment and the suitable cooperation of paint vehicle, and the paint film of formation densification is to stop the intrusion of corrosive substance, such as iron oxide red, ethyl acetate, graphite antirust paint etc.；The latter presses down rust effect, such as Plumbum preparatium, barium sulfate antirust paint etc. by the chemistry of rust resisting pigment.Antirust for metals such as bridge, boats and ships, pipelines.
Iron and steel is with being steel mill molding large casting unit of producing that indispensable, turnover uses, and the surface of steel ingot and internal soundness and steel ingot cost are had a major impact by it.Steel propylene glycol is so as to the press mold of coagulation forming.Iron and steel is with being steel mill molding large casting unit of producing that indispensable, turnover uses, and the surface of steel ingot and internal soundness and steel ingot cost are had a major impact by it.Iron and steel life-span (secondary) or iron and steel consume the main economic and technical indices that (kg/t steel) is STEELMAKING PRODUCTION.
Anticorrosive coating refers to coat body surface and can form thin film under certain conditions and play protection, a class I liquid I of decoration or other specific functions (insulation, antirust, mildew-resistant, heat-resisting etc.) or solid material.Because coating in early days is mostly with vegetable oil as primary raw material, therefore also referred to as paint.Now synthetic resin the most largely or entirely instead of vegetable oil, therefore referred to as coating.
The film forming matter of anticorrosive coating has chemical stability in corrosive medium, and its standard is relevant with the composition of film forming matter and chemical constitution.It is primarily to see it under the conditions of dry film whether easily and corrosive medium reacts or resolves into little molecule in media as well.
The coating that anticorrosive paint is formed after coated article surface of bottom material dry solidification, its protective effect mainly has following three kinds, shielding action, according to electrochemical corrosion principle, the corrosion of iron and steel is it is necessary to have oxygen, water and the existence of ion, and the approach of ion circulation point conduction, paint film prevents the existence of corrosive medium and material surface, the path cutting off corrosion cell adds resistance, water, the seepage velocity of oxygen and ion pair paint film is different, the seepage velocity of water is far longer than ion and oxygen, reason straight infiltration paint film is less, they direct effects to ground metal can not be considered.Combine the representative that high density chlorinated polyvinyl chloride paints spraying polyurea elastic coating is the international up-to-date anticorrosion technique of a new generation, at present, the petroleum pipeline company indicated in the world is all the use of polyurea anti-corrosion layer, it is worth mentioning that, spraying polyurea elastic coating is used for pipe joint, there is the workability of excellence, general straight-tube portion can keep seriality and the integrity become reconciled, whole tubing is made to seal complete, seamless, ensure that the overall Corrosion Protection of pipeline, the sharpest edges using this coating are exactly, it is coated with pipe fitting need not heat, it is exothermic reaction during polyureas molding.
Anticorrosive paint, is generally divided into conventional anticorrosive paint and anticorrosive paint, is requisite a kind of coating in paint.Conventional anticorrosive paint is under general condition, and metal etc. plays etch-proof effect, the life-span that protection non-ferrous metal uses；For anticorrosive paint refers to relatively conventional anticorrosive paint, can apply in relatively harsh corrosive environment, and there is the class anticorrosive paint that can reach the protection period more longer than conventional anticorrosive paint.
Steel structure anti-corrosion paint is a kind of new steel structure anticorrosive coating succeeded in developing on the basis of oil resistance anticorrosion erosion coating.This coating is divided into priming paint and finish paint two kinds, except in addition to, its range of application is wider, and can be as required by coating furnishing shades of colour.
Steel-structure factory building, steel box girder bridge, TV steel tower, building antenna, send the outdoor steel construction such as transformer station, steel lamp stand, these steel beam column are because being chronically exposed in air, by climate change with expose to the sun and rain, rapid surface oxidation, generate one layer of iron sesquioxide, have a strong impact on intensity and the service life of steel construction.For preventing the oxidation of steel structure surface, typically all using paints and lacquers protection, its anticorrosion time limit is typically at 3-5, it is therefore desirable to regular carrying out is keeped in repair, maintains in the past, and common method copies shovel paint exactly, expends a large amount of manpower and materials.Now using steel structure surface spray zinc, aluminum spraying technique to be protected by, the anticorrosion time limit was up to more than 30 years service frees.Close as refueled stop-off lacquer outside Aluminum Coating again, then the anticorrosion time limit is longer.
Steel structure surface only spray zinc, aluminium-plated after, could really play anodic protection effect, thus reach the purpose of steel construction long-effective corrosion.Therefore the many Important Project of country and municipal project are designated and use this technique.As: the permanent gate in the Yangtze River Gorges, Shanghai Oriental Pearl television tower, the main guard bar of Yangpu Bridge, the overhead girder steel of Guangzhou internal ring, Shanghai stock building steel construction antenna, pudong airport road common trench gas explosion pipeline, 500,000 kilowatts of transformer stations of Shanghai south bridge etc., to guarantee the project of vital and lasting importance of Important Project.
Along with social city, technicalization, the development of hommization, design a kind of ageing-resistant, impact strength is high, adhesive force is high, adhesion strength is high and pliability is good iron and steel antirust, anti-corrosive finish paint and preparation method thereof, to meet the market demand, be very important.
