Description
Technical field
What the present invention relates to be used for the metallic surface prevents metallic corrosion and compsn that gets rusty and application thereof, is specifically related to anti-corrosion of metal rust-proofing coating and application thereof.
Background technology
The building that metals such as iron and steel constitute and framework owing to long-term exposure in atmospheric environment; Standing steam, oxygen and wind etc. in the atmosphere for a long time has the erosion of the obnoxious flavour of corrosive nature to the metallic surface; Corrosion must appear in metal self; Especially in some local atmosphere, contain in the environment of sour gas such as hydrogen sulfide, sulfurous gas, add the steam mixing effect in the atmosphere again, aggravated the corrosion of hardware especially.For example: how long have more than is needed the metal construction of these local output zone such as some chemical plant, Iron And Steel Plant, coking plant, power station and cross a river metal bridge is, and overhaul must eliminate rust.The work-ing life of hardware is shortened in the corrosion meeting of metal greatly, can fall in flakes when serious, and influence himself intensity and cause caving in, jeopardize safety and sight.
For generation, the development that stops corrosion of metal, have to carry out the rust cleaning of metal, antirust, corrosion prevention operation.Traditional rust cleaning, antirust, corrosion prevention operation method are: at first polished in the surface, metallic surface; Expose metal essence, evenly be coated with anticorrosive paint then, generally be coated with 2-3 time; Paint dries back formation one deck dura mater and covers the metallic surface; Isolated metallic surface contacts with atmospheric, thereby reaches antirust, the rot-resistant purpose.Because this layer duricrust and metallic surface fit tightly; And metal and paint expansion and contraction when deformation, temperature variation is different; Therefore the crack will appear in the paint duricrust in the process of temperature, deformation, and atmosphere will be penetrated into the metallic surface, and metal begins again to get rusty.As time goes on, rust staining enlarges gradually, thickeies under the paint duricrust, and last and paint duricrust comes off together, and metal is exposed in the middle of the atmosphere once more.According to investigations, for antirust following several method arranged now: 1) metal self is antirust forms passive film with alloy material.This kind method cost is higher, is unfavorable for welding, and construction is inconvenient, and especially more large-scale member possibly not used this material.2) metal-plated metallic membrane.This method is usually used in the construction of pipeline and section bar, the operation that in construction, often will weld, punching, mantle fiber etc. damages plated film, and just in these manufacturability destructive positions, metal essence has been exposed to again in the atmosphere, and extremely hard to manage behind the one-tenth rust staining.3) electrodeposition coated film and plastic-blasting plated film.These two kinds of methods are mainly used in kart and household electrical appliance; Because the area of these metals is not that very big daily deformation is limited, therefore, its life-span is longer than general anti-corrosive technology; But, be very large in case damage the cost and the technology difficulty of its reparation and making.4) the aforementioned anticorrosive paint method of filming, this method is the most common, the most common, the operation most convenient, but enamelled coating comes off easily.
Summary of the invention
To corrosion, the serious problem of getting rusty now, the invention provides the anti-corrosion of metal rust-proofing coating of two kinds of different ingredients, these two kinds of coating are easy to use, and are strong with metallic cohesion, difficult drop-off, anticorrosion, favorable rust preventing effect.
The present invention also provides the application that coating is used for anti-corrosion of metal rust-proofing field.
The present invention realizes through following measure:
First kind of anti-corrosion of metal rust-proofing coating is made up of following component in percentage by weight: pitch 60-90%, metal protector 5-30%, metal penetration agent 5-35%.
In the above-mentioned anti-corrosion of metal rust-proofing coating, preferably form: pitch 70-90%, metal protector 5-20%, metal penetration agent 5-25% by following component in percentage by weight.
In the above-mentioned anti-corrosion of metal rust-proofing coating, said pitch is coal tar pitch, petroleum pitch or modifying asphalt, and said modifying asphalt is SBS modifying asphalt, APP modifying asphalt or IPP modifying asphalt; Said metal protector is lauric monoglyceride, paraffin, Vaseline, butter, Vinlub or ether of cellulose, is preferably paraffin, Vaseline or butter; Said metal penetration agent is silicone oil, kerosene, gasoline, chloroform, toluene, diesel oil or machine oil, is preferably silicone oil, kerosene, gasoline or machine oil.
The contriver successfully develops a kind of new anticorrosion, rust proof paint through years of researches and practice, and this coating is the thickness state, and is similar with paint, therefore can claim that also this coating is anticorrosion rust-proofing paint film.In this coating, the metal penetration agent is the very low antirust material of a kind of viscosity, its ability dissolution of metals rust-preventive agent and pitch, but the dissolving ratio is different.When coating and metallic contact, the metal penetration agent can carry the little metal protective agent rapidly and pitch permeates to the metallic surface, thereby forms the first layer paint film.The effect of this layer paint film is to play the effect that the metallic surface is fully soaked into, and for protective agent and the further film forming of bituminous lay the first stone, so this tunic also can be described as the infiltration film.Protective agent is the relatively low material of a kind of viscosity; Relatively more responsive to temperature and metal penetration agent, when invading profit film surface, formation second layer paint film with invading can cover uniformly after the profit film contact; Antirust, rot-resistant effect that this layer paint film has, so this tunic also can be described as protective film.Li Celadon viscosity is higher, and is slower to thermotonus, therefore last film forming, and attached to becoming the 3rd layer of paint film on the protective film, this layer paint film plays the effect of secluding air and obnoxious flavour the most surperficial, can be called protective membrane.The above-mentioned formation mechanism that is coating of the present invention attached to the metallic surface; When actually operating, need not gradation operate; As long as with the disposable brushing of the coating for preparing or be sprayed on the metallic surface, can form 3 layers of paint film voluntarily to the different of affine degree of temperature, viscosity and metal according to composition in the coating.
Further; In order better to improve the antirust, anti-corrosive effect of coating; In coating, can also add polyamino polyether methylene phosphonic acids, this composition has preservative activity, joins in the coating part to adhere to and the metallic surface with the metal penetration agent; Rest parts is mixed formation second layer paint film with metal protector, play protective effect.The prescription that adds the second kind of coating that forms behind the polyamino polyether methylene phosphonic acids is (weight percent): pitch 60-85%, polyamino polyether methylene phosphonic acids 5-15%, metal protector 5-30%, metal penetration agent 5-30%.Used pitch still is coal tar pitch, petroleum pitch or modifying asphalt, and said modifying asphalt is SBS modifying asphalt, APP modifying asphalt or IPP modifying asphalt; Said metal protector is lauric monoglyceride, paraffin, Vaseline, butter, Vinlub or ether of cellulose, preferred paraffin, Vaseline or butter; Said metal penetration agent is silicone oil, kerosene, gasoline, chloroform, toluene, diesel oil or machine oil, preferred silicone oil, kerosene, gasoline or machine oil.
The present invention also provides the application of above-mentioned two kinds of anti-corrosion of metal rust-proofing coating in anti-corrosion of metal rust-proofing field, and these two kinds of anticorrosion with coat rust-proof effects are all fine, and cost is low, has very vast market prospect.
The preparation method of coating of the present invention is simple, as long as each composition is proportionally mixed, stirring gets final product.In use, the same with the traditional paint construction, need under certain temperature condition, carry out, draw through practice, coating of the present invention is best temperature 30-60 ℃ of construction, preferred 40-55 ℃.Therefore, hot weather construction is easy to construction than the winter, if temperature does not reach the coating suitable condition, can adopt external heat source to be heated to 30-60 ℃ coating, alleviates construction again behind its sliminess.Before construction, metal is carried out advanced processing, the rusty stain of metallic surface is removed, expose metal body, and then with paint spay-coating or brush in the metallic surface.In order to strengthen the bonding strength of coating and metal, preferably also the metallic surface is heated to 30-60 ℃, the best is heated to 40-55C.The coating thickness of coating is generally between 1-2mm.
Coating raw material of the present invention is easy to get, and preparation is simple, as long as simple mixing can obtain, each composition has different effects in the coating, can form 3 layers of paint film that adhere to each other in the metallic surface, and metal is fully isolated with extraneous.Compare with traditional pitch protective paint, long service life of the present invention, easy to crack, come off, adverse environment resistant can not play good antiseptic and rustproof effect yet in severe environment such as high temperature, sour vapour.
