Description

A kind of iron and steel water-soluble anti-rust coating and preparation method thereof
Technical field
The present invention relates to steel surface coating, particularly relate to a kind of iron and steel water-soluble anti-rust coating and preparation method thereof.
Background technology
Antirusting paint can protect metal surfaces from the chemistry of air, sea water etc. or the coating of electrochemical corrosion.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 ammonia 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, butanone antirust paint etc.；The latter presses down rust effect, such as pure water, zinc chromate anti-rust paint etc. by the chemistry of antirust ammonia.Antirust for metals such as bridge, boats and ships, pipelines.The antirust paint substantially oily antirust varniss used and aqueous antirust paint two kinds.Oily antirust varniss makes material surface greasy removal difficulty, is rarely employed.Oily antirust varniss is easy to use, cheap, but because containing the noxious substance such as nitrite, chromate, relatively big to operator's harm, country has limited use, and these type of properties of product are single, it is impossible to meet the antirust requirement of magnetic alloy material.Selecting metal strength chelating agen inositol hexaphosphate is main component, compounds with other several aqueous promoters and forms.Inositol hexaphosphate is the Nantural non-toxic Organic chemical products extracted from cereal crops, when it uses as magnetic material antirust agent, can chelate rapidly with metal on surface, form one layer of fine and close unimolecule complex protecting film, can effectively suppress corrosion of metal.Material surface after this product treatment keeps primary colors, it is not necessary to washing can enter the next procedures such as application.The important component part of antirust paint. the antirust ammonia of physics be a class more antirust ammonia of chemical property own be stable ammonia, they are the physical properties by itself, stable chemical performance, quality is hard, granule is trickle, excellent fillibility, improve the consistency of paint film, reducing the permeable of paint film thus play antirust effect. polyoxyethylenealkylphenol ether is red just belongs to this kind of material. and the rust-preventing characteristic of metallic aluminium powder is owing to aluminium powder has sclay texture, formation paint film is tight, also have the ability of stronger uv reflectance light, paint film aging-resistant ability can be improved.
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 molten steel 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, butanone 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 water-soluble resin.The mechanism of action of water-soluble resin is: the splash droplet produced when cast is bonded at and scribbles the ferrum of resin when use, and this layer of resin can produce decomposition reaction under the temperature conditions of 400～600 DEG C, discharge gas so that splash droplet solidify after Automatic-falling.Research shows, when the high-temperature viscosity of water-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 molten steel.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.Molten steel 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.
The antirust paint substantially oily antirust varniss used and aqueous antirust paint two kinds.Oily antirust varniss makes material surface greasy removal difficulty, is rarely employed.Oily antirust varniss is easy to use, cheap, but because containing the noxious substance such as nitrite, chromate, relatively big to operator's harm, country has limited use, and these type of properties of product are single, it is impossible to meet the antirust requirement of magnetic alloy material.
Selecting metal strength chelating agen inositol hexaphosphate is main component, compounds with other several aqueous promoters and forms.Inositol hexaphosphate is the Nantural non-toxic Organic chemical products extracted from cereal crops, when it uses as magnetic material antirust agent, can chelate rapidly with metal on surface, form one layer of fine and close unimolecule complex protecting film, can effectively suppress corrosion of metal.Material surface after this product treatment keeps primary colors, it is not necessary to washing can enter the next procedures such as application.
Along with social city, technicalization, the development of hommization, design good iron and steel water-soluble anti-rust 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.
