Description
Technical field
The present invention relates to the metal rust preventing technical field, especially a kind of rust-stabilising pigment.
Background technology
The financial loss that whole world every year causes because of metallic corrosion is higher than the summation of lose from natural calamity such as earthquake, fire, typhoon up to 7,000 hundred million dollars.In China,, account for 4% of gross national product because the loss that metallic corrosion caused also is huge.In order to prevent that metal from corroding, can adopt diversified safeguard procedures such as biology measure, metallurgy, electrochemistry measure and coating protection measure.Wherein applying erosion shield in the metallic surface is to prevent one of method that metallic corrosion is effective, the most the most frequently used, and this is because adopt the coating protection suitability strong, both economical, in addition, can will protect and effect such as decoration combines.
The resin system of being selected for use is not only depended in the coating protection metallic corrosion, also depends on selected rust-stabilising pigment to a great extent simultaneously, and therefore, the antiseptic property of coating is the mutual coefficient result of resin system and rust-stabilising pigment.Rust-stabilising pigment in the market is of a great variety, can be divided into inertia rust-stabilising pigment (shielding pigment), sacrificial pigment, active rust-stabilising pigment three major types basically:
1, the inert pigment performance is physical action, and it can strengthen the shielding effect of filming, and in general, they chemically are being inert;
2, sacrificial pigment is metallic pigment, belongs to special a type in the reactive pigment, is sprayed on the iron dust base material, brings into play rustless property through the galvanic protection effect;
3, reactive pigment through the chemistry and (or) electrochemical action prevents metallic corrosion, is the main flow of rust-stabilising pigment,, the present invention just belongs to this type of.
To slow down corrosion, they have the effect of pH value, generation saponification reaction and the passive metal of the coating kept to reactive pigment directly or through midbody and metal base generation interaction.The kind of active rust-stabilising pigment has a lot, mainly comprises: lead pigment (like red lead), chromate pigments (like zinc-chrome yellow, lead-chrome yellow etc.), phosphoric acid salt, molybdate, metaborate etc.
For a long time; That coatings industry uses is leaded, chromium (VI) is though the rustless property that waits the rust-stabilising pigment of toxic heavy metal to have excellence; But its toxicity is big, color is dark, and the rust-proofing primer of configuration needs the finish paint of high covering power supporting, brings very big difficulty for the deep processing of paint industry.In addition; The gas that distributes when welding is with cutting behind the dust that leaded, chromium (VI) pigment produces in the three wastes that production process produces, system lacquer process, the metallized paint and the poisonous paint film behind the coating damage or the like all can cause serious harm and pollution to human body and environment; Therefore, the production of this type pigment progressively is restricted with use.Along with the strictness and perfect day by day of the environmental legislation of global various countries, legislation on labour protection and industrial hygiene standard, seek the ecological rust-stabilising pigment of nontoxic or low toxicity and progressively replace the common recognition that the traditional poisonous rust-stabilising pigment has become people.
Britain scholar Coslett T W. was a purpose to prevent that iron and steel from getting rusty in 1906, had invented with the treating method of phosphoric acid salt as rust-preventive agent.Nineteen fifty-nine Britain Harrison J B. etc. has carried out industrial performance test to zinc phosphate rust-preventive pigment first.Japan in 1972 is poisonous pigment such as the opportunity chromic salt bringing into use poly aluminium phosphate series non-poisonous antirust pigment to substitute to contain chromium, lead and red lead with the pollution problem, promotes the use of in countries such as China, West Europe, the U.S. gradually later on.Up to now; Multiple pigment such as phosphate-based, molybdate series, borate series have been developed and have developed; Wherein all occupy bigger advantage with regard to the research on its kind, performance and the use range, thereby make it become the maximum non-poisonous antirust pigment of consumption with series of phosphate pigment.
Several families relevant enterprise of taking as the leading factor with University Of Hebei such as the pigment company and China of Germany, the U.S., Japan a series of novel antirust pigment such as zn phosphate, modified zinc phosphate, polymer phosphate aluminium that released one after another from the later stage eighties in last century, its rustless property are quite or to be superior to traditional lead system, chromium be poisonous rust-stabilising pigment.But the subject matter that exists at present is; These phosphoric acid salt rust-stabilising pigment costs are quite high, and (such as present zn phosphate market price is 1.5 ten thousand yuan/ton; Polymer phosphate aluminium is 1.3 ten thousand yuan/ton), make the widely-used and popularization of these non-poisonous antirust pigments be restricted.
Summary of the invention
The technical problem that the present invention will solve provides a kind of nano-oxide coated phosphate rust-stabilising pigment, and it not only has good metal rust preventing performance, and price is very cheap simultaneously; For this reason, the present invention provides the preparation method of this rust-stabilising pigment simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention taked is following.
Nano-oxide coated phosphate rust-stabilising pigment, this rust-stabilising pigment are that nano-scale oxide is coated on the composite antirust pigment that forms on the micron order phosphoric acid salt; The phosphatic weight ratio of nano-scale oxide and micron order is (1-10): 100.
As a kind of optimal technical scheme of the present invention, said oxide compound is titanium oxide or zinc oxide, and its particle diameter is 2-30nm; Said phosphoric acid salt is calcium phosphate, and its particle diameter is 0.3-5 μ m.
