Description
Technical field
The invention belongs to paint field, in particular to a kind of Steel surface anticorrosive paint.
Background technique
Metal erosion spreads national economy and national defense construction every field, endangers extremely serious.Firstly, corrosion will cause weight
Big direct or indirect economic loss.According to the statistics of the country of industry prosperity, because economic loss accounts for about current year caused by corroding
The 1.5%-4.2% of national economy total output value.Secondly, metal erosion, especially stress corrosion and corrosion fatigue, often make
At catastrophic major accident, jeopardize personal safety.Furthermore a large amount of metals are not only lost in corrosion, and waste mass energy, often
Year, the metal of 10%-20% will be lost because corroding.In addition, in the industrial productions such as petroleum, chemical industry, pesticide, because being set caused by corrosion
Standby run, drip, leak, not only cause economic loss, it is also possible to make hazardous material situations, cause environmental pollution, it is strong to jeopardize the people
Health.Meanwhile corrosion is also possible to the obstacle as production development and scientific and technological progress.
Micaceous iron oxide is a kind of excellent physical rust resisting pigment of resistant to chemical media, in antirusting paint, is had fine
It is water-fast act on impervious, have certain albedo to ultraviolet light.The antirusting paint made of micaceous iron oxide is answered extensively
Anti-corrosion protection for fields such as bridge, electric force pole tower, oil storage tank, tank car and engineering machinery.
Existing micaceous iron oxide the problem is that, since micaceous iron oxide is physical rust resisting pigment, to steel without passivation
Effect, Corrosion Protection is undesirable, it is necessary to cooperate the anticorrosion ability that can be only achieved with the pigment containing chromium or lead, and contain chromium or
The material of lead has serious contamination to environment.
Antirusting paint can protect metal surfaces from the chemistry of atmosphere, extra large vermiculite power etc. or the coating of electrochemical corrosion.?
Antirusting paint is coated in metal surface can effectively avoid the direct invasion of various corrosive substances in atmosphere, so that maximumlly
Extend metal service life.Physical and chemically antirust paint two major classes can be divided into.The former leans on the appropriate cooperation of pigment and paint vehicle,
Fine and close paint film is formed to prevent the intrusion of corrosive substance, such as iron oxide red, aluminium powder, graphite antirust paint；The latter leans on rust resisting pigment
Chemistry suppression rust effect, such as red lead, zinc chromate anti-rust paint.Antirust for metals such as bridge, ship, pipelines.
Conversion and prevention paint of rust is transformant solvent bottom paint, has excellent derusting, rustless property, can directly brush is having rust
The metal surface of (thickness≤100 μm) simplifies derusting process, improves work efficiency, reduces cost.The paint is in rustless metal
Surface also can be used；It can be matched with a variety of finishing coats；It can construct under the conditions of -20 DEG C.
It is applied to the metal surface of residual rust, residual rust can be made to stablize, be passivated or conversion, active iron rust is made to become harmless object
Matter, to reach the dual purpose for not only derusting but also protecting.Such coating is by oil plant, resin, pigment, solvent or diluent and other auxiliary materials etc.
Composition.The classes such as stable type, osmosis type, transformant and steadyization type are divided into corrosion product role according to primer for rusted steel, wherein
Respectively added with substances such as stable rust, bleeding agent, transforming agents.
With social city, technicalization, hommization development, design that a kind of hardness is high, impact strength is high, adhesive force
High, fast drying and the good steel Corrosion resisting paint without need of cleaning rust and preparation method thereof of flexibility, are very necessary to meet the market demand
's.
