Description

Compound on rust paint of steady seepage and preparation method thereof
Technical field
The present invention relates to the anticorrosive paint for metal, particularly relates to a kind of be applied to the new of rust metal base Coating.
Background technology
Influenceed by contemporary metal industry fast development, various metal industries start to pay close attention to the anti-corrosion of metal material emphatically With protected working.According to statistics, 1/5th of annual whole world year metal total output damage because corrosion of metal gets rusty, by becoming rusty Lose the RMB of economic loss about 6,500,000,000,000 brought./ 25th of annual China gross national product is because of metal material Corrosion and lose, considerably beyond losing summation caused by natural calamity.
Traditional coating antiseptic must first carry out strict processing derusting to metal surface.But because execution conditions etc. influence, It is difficult to obtain desired metallic surface, and cost is higher.But if using Rust-resisting coating, problem above is then readily solved.
Rust-resisting coating refers to directly brush a kind of antirusting paint on undressed corrosion metals surface, it In addition to the performance with general antirusting paint, also two special performances.First, Rust-resisting coating has foot to rusty scale Enough penetrating powers, it can fully soak and permeate whole rusty scale, rusty scale, which is bonded, turns into continuous closure coating, by steel Surface and rusty scale completely enclose.Second, Rust-resisting coating can pass through chemical reaction with the active iron compound being harmful in rusty scale It is allowed to be passivated or converts, becomes stable inert filler.Because the Rust-resisting coating has numerous other coating incomparable The advantages of (excellent performance, easy for construction, price is low etc.), therefore when selecting antirusting paint often by as the painting considered at first Material, is up to the present most effective, most practical, most economical feasible anti-corrosion measure using the Rust-resisting coating.
Rust-resisting coating is divided into according to reaction mechanism：Transformant Rust-resisting coating and stable type Rust-resisting coating two Kind
The rust-proof mechanism of transformant Rust-resisting coating is that the transforming agent in coating and rusty scale reaction generation are harmless to matrix Stable material not only played a part of derusting but also play a part of install additional coating.It can be brushed in the thicker metal watch of rusty scale Face, turn rust speed ratio is very fast, but a disadvantage is that acidity itself is presented, pH value can destroy matching used finish paint less than 3, Supporting finish paint can be made to be cracked and become fragile, therefore it is required that supporting finish paint should be acidproof.Transformant Rust-resisting coating turns rust effect It can be influenceed by steel surface corrosion state, because its presentation acidity can corrode rustless steel structure surface destruction steel construction and increase Fast rusting rate, therefore, rust-converter coating, which is only coated on uniform rusty surface, can just play good effect, but be coated in Smaller anti-rust action can be played on the uneven metal surface of corrosion can possibly even produce the harm of unrepairable, rusty scale Thicker place may convert not thoroughly, and the relatively thin position of rusty scale can corrode metal surface because conversion fluid is too many, speed corrosion Speed.These can all cause corrosion resistant coating adhesion and anti-corrosion effect significantly to decline.
The rust-proof mechanism of stable type Rust-resisting coating is that the reactive pigment in coating reacts generation stably with iron rust Compound precipitation, chelate, complex compound etc. so that rusty scale is passivated, this coating is generally equipped with the preferable resin of permeability, Pigment can be made fully to penetrate between rusty scale and base material.Stable type Rust-resisting coating can only be coated in iron rust in the case of no special The relatively thin corrosion metals surface of layer, but due to the more preferable match surface coating of stable type Rust-resisting coating energy, without special It is required that so it can be almost used cooperatively with various investment precoats.In addition, the use of this type antirusting paint is become rusty with steel construction Erosion state is unrelated, no matter poor or preferable steel structure surface can obtain good effect in corrosion situation, in steel construction There is good adhesive force at the heavier place of surface corrosion, and it is outstanding gentlier to locate various performances in corrosion.
The technology relevant with the present invention is stable type Rust-resisting coating.
