Description
Technical field
The present invention relates to steel surface coating, particularly relate to a kind of iron and steel epoxy resin Rust-resisting coating and preparation method thereof.
Background technology
Antirusting paint can protect metal surfaces from chemistry or the coating of electrochemical corrosion of air, sea dibutyl phthalate 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, aluminium powder, graphite antirust paint etc.；The latter presses down rust effect, such as Plumbum preparatium, zinc chromate anti-rust paint etc. by the chemistry of rust resisting pigment.Antirust for metals such as bridge, boats and ships, pipelines.
Ingot coating is to eliminate ingot surface defect and to reduce the iron and steel inner surface Liniment for the purpose of iron and steel consumes.It being sprayed at equably on iron and steel inner surface with special spraying equipment during use, in casting process, this coating film makes the kinds of surface defects such as the scabbing of steel ingot, skull patch, crackle, blibbing and rimhole be suppressed greatly.Meanwhile, which reduce steel ingot weldering mould phenomenon and prevent steel dibutyl phthalate to the erosion on ferrum surface and to wash away, playing the effect of protection iron and steel.Additionally, the setting time that the heat-blocking action of this coating makes steel ingot extends accordingly, decrease the formation of steel ingot shrinkage cavity to a certain extent and extend the floating interval of floating dock being mingled with accordingly, being conducive to it to get rid of.Ferrum coating is divided into two classes: a class is die wall coating, and another kind of is mould primer.Die wall coating was many with coal tar, heavy oil, graphite etc. as matrix material in the past, owing to its heat decomposition temperature differs carburizing that is relatively big and that can cause die wall carbon residue attachment area seriously with optimum, was replaced by dibutyl phthalate soluble resin.The mechanism of action of dibutyl phthalate soluble resin is: the splash droplet produced when cast is bonded at and scribbles the ferrum of resin when using, this layer of resin can produce decomposition reaction under the temperature conditions of 400～600 DEG C, discharge gas so that splash droplet solidification after Automatic-falling.Research shows, when the high-temperature viscosity of dibutyl phthalate soluble resin decomposition residue is between 1000～3000cst, the surface quality of steel ingot is more excellent.It addition, iron and steel coating to be also had some additional requirements.One is that heat conductivity is low, with ferrum with there being strong adhesive force, preferably has certain surface strength and anti-urgency hot under high temperature.Mould primer refers generally to base plate coating, base plate healant and leak preventive.This kind of coating mostly is siliceous, aluminum matter or magnesian, will not pollute steel dibutyl phthalate.Use spraying method more, be the most also made into cement paste with manual coating.
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 dibutyl phthalate 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.
Conversion and prevention paint of rust is transformant solvent bottom paint, has the rust cleaning of excellence, rustless property, can directly brush in the metal surface having rust (thickness≤100 μm), simplify rust cleaning operation, improves work efficiency, reduces cost.This paint also can use in rustless metal surface；Can support the use with multiple finish paint；Can construct under the conditions of-20 DEG C.
Paint film appearance paint film is smooth, allow slightly brush mark, this paint can be widely applied to the surface derusting operation of all steel components such as vehicle, container, boats and ships, machinery, building, steel casement door window, steel tower, pipeline, bridge, billboard, ferrum railing, boiler, makees priming paint and uses.
Band rust anti-corrosive primer is made up of epoxy resin, zinc powder, turn rust agent, firming agent, auxiliary agent and solvent etc., it is widely used in the substrate body that iron and steel, galvanized steel etc. got rusty to fasten and make priming paint and use, it is the optimal priming paint of epoxy intermediate layer paint, epoxy finish, polyurethane finish, chlorinated rubber finish etc., it is usually used in steel-slag sand, workshop steel structure etc. under large bridge, plant equipment, oil, metallurgy, electric power, chemical industry equipment, dibutyl phthalate and makees high performance tape rust anti-corrosive primer, good rust transformation function, capable of coating with rust.
It is applied to the metal surface of residual rust, residual rust can be made to stablize, be passivated or convert, make active rust become innocuous substance, to reach the dual purpose not only eliminating rust but also protecting.This type of coating is made up of oil plant, resin, pigment, solvent or diluent and other auxiliary materials etc..According to primer for rusted steel, corrosion product role is divided into the classes such as stable type, osmosis type, transformant and steadyization type, the most respectively added with materials such as stable rust, penetrating agent, transforming agents.
Along with social city, technicalization, the development of hommization, design good iron and steel epoxy resin Rust-resisting coating of a kind of hardness height, impact strength height, adhesive force height, fast drying and pliability and preparation method thereof, to meet the market demand, be very important.
