Abstract
The utility model provides a kind of super-hydrophobic band rust coating structure being suitable for wet weather metal rust preventing, and described coating structure comprises the band rust being sprayed on metallic substrate surface successively and processes liquid layer, PH regulating course and super-hydrophobic top layer, and described PH regulating course is alkaline coating.Need meticulous for metal base polishing to solve before existing antirust coat uses, cost is high, and noise is large, and efficiency is low, and dust is large, and quality can not be guaranteed, and after spray-on coating metal base counter become rusty fast, the problem of rust-proof effect difference.The utility model belongs to metal rust preventing field.
Description
Technical field
The utility model relates to a kind of antirust coat structure, belongs to metal rust preventing field.
Background technology
Corrosion generation be metal in the process having water to participate in, a kind of electrochemical reaction of formation, in order to prevent corrosion generation, must fundamentally stop entering of moisture.Common anticorrosive paint construction, all has strict requirement to substrate surface, generally, metal base must be polished to sa2.5 level, and this kind of method cost is high, and noise is large, efficiency is low, dust is large, and quality can not be guaranteed, the particularly this high humidity in Guizhou, the area that the rainwater time is long, polishing rust cleaning institute is restricted very large, and it is fast to return rust, and coating life is shortened greatly.At present, anticorrosive paint on the market, service condition is harsh, and water-fast resistance to calculation is not enough, can not stop the infiltration of moisture completely.
Utility model content
The purpose of this utility model is: provide a kind of super-hydrophobic band rust coating structure being suitable for wet weather metal rust preventing, need meticulous for metal base polishing to solve before existing antirust coat uses, cost is high, noise is large, efficiency is low, and dust is large, and quality can not be guaranteed, and after spray-on coating metal base counter become rusty fast, the problem of rust-proof effect difference; In addition, the utility model adopts super-hydrophobic surface layer, is infiltration from the moisture stopped of extraneous essence, has stopped the generation of corroding from source.
Scheme of the present utility model is as follows: a kind of super-hydrophobic band rust coating structure being suitable for wet weather metal rust preventing, described coating structure comprises the band rust process liquid layer being sprayed on metallic substrate surface successively, PH regulating course and super-hydrophobic top layer, described PH regulating course is alkalescent coating, after metallic substrate surface spraying band rust process liquid layer, band rust treatment fluid can transform by the corrosion moiety chelates active with metallic substrate surface, form fine and close inertia protective layer, although existing different types of band rust treatment fluid composition and each constituent content have certain difference, but their general principle is all identical, all can realize the object that the corrosion moiety chelates active with metallic substrate surface transforms, at the PH regulating course of the outside spraying alkalescence of band rust process liquid layer, acidity unnecessary in neutral zone rust process liquid layer, the infiltration of moisture can be avoided in the super-hydrophobic top layer in outside, effectively prevent metal base from corroding again.
Preferably, between PH regulating course and super-hydrophobic top layer, be also coated with antiacid corrosion surface layer, prevent super-hydrophobic top layer by acid etching.
Preferably, PH regulating course is alkalescent layer of silica gel, and the rich zinc layer of silica gel of preferred alkalescent, possesses certain acid resistance, resistance to water and ageing-resistant performance.
Preferably, super-hydrophobic top layer is nano TiO 2/fluor resin coating, contact angle > 165 °.
The band rust process liquid layer of described spraying is the band rust treatment fluid in metallic substrate surface spraying, and band rust treatment fluid to transform by the corrosion moiety chelates active with metallic substrate surface, forms a kind of metal surface of fine and close inertia protective layer
The utility model compared with prior art, major advantage adopts super-hydrophobic band rust coating structure described in the utility model, without the need to carrying out meticulous polishing to metallic substrate surface, directly active iron rust layer can be transformed at metallic substrate surface spraying band rust process liquid layer and be chelated to fine and close inertia protective layer, after the outside of band rust process liquid layer sprays PH regulating course and super-hydrophobic top layer successively, neutral zone rust process liquid layer is acid, simultaneously, super-hydrophobic top layer can prevent the infiltration of moisture effectively relative to existing antirust coat, prevent metal base generation corrosion, ensure that the metal base after spraying by moist weather effect, anti-rust does not occur, be particularly useful for southern humidity comparatively large as Guizhou, the areas such as Yunnan, practical effect is very good.
