The amount for adding water, after adding water, 70~85 DEG C of constant temperature, 1~2h of stirring compounding obtains combination solution；
(4) addition of film forming agent: then mixing polyethylene glycol and polyvinyl alcohol are added in combination solution obtained by (3), heat preservation
It 70~85 DEG C, is completed after continuing 30~40min of stirring.
The present invention has the advantages that adding phytic acid in order to solve the defect for the antirust agent that silicate is host agent preparation and gathering
Aspartic acid improves the shortcomings that host agent forms a film as additive, when handling metal surface with plant acid solution, easily in metal surface shape
Gap is reduced to inhibit corrosion of metal at one layer of fine and close unimolecule protective film, after compounding with silicate, effectively
Keep silicate film forming crosslinked together, becomes a similar netted protective film；
Polysucciuimide is a kind of biodegradable environment-friendly type corrosion inhibiter as a kind of novel non-phosphorus water chemical treatment agent,
The activation energy of metal ionization is improved, non-polar group then makees oriented alignment far from metal surface, forms one layer of hydrophobic membrane, inhibits
Corrosion reaction, the shortcomings that being effectively improved host agent poor water resistance.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in the embodiment of the present invention
Technical solution is clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than complete
The embodiment in portion.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment:
A kind of waterborne anti-rust sealer, including 65ml/L phytic acid, 25ml/L Polysucciuimide, 30g/L sodium metasilicate, 4g/L tungsten
Sour sodium, 5g/L polyethylene glycol, 8g/L polyvinyl alcohol, 2ml/L triethanolamine and surplus water.
A kind of preparation method of waterborne anti-rust sealer, including following steps,
(1) host agent dissolves: in isothermal reaction kettle, sodium metasilicate, sodium tungstate, triethanolamine is sequentially added, by total after mixing
Amount is that the ratio of 1:50 adds water, and 85 DEG C of constant temperature in reaction kettle stir 35min, and host agent is obtained after diverging；
(2) additive dissolves: mixing phytic acid and Polysucciuimide, the ratio of 1:10 adds water by volume, and 70 DEG C of constant temperature are stirred
Diverging 20min is mixed, additive is obtained；
(3) host agent and additive compound: mixing host agent and additive determine and mended by each components and concentration precalculated
The amount for adding water, after adding water, 75 DEG C of constant temperature, stirring compounding 1.5h obtains combination solution；
(4) addition of film forming agent: then mixing polyethylene glycol and polyvinyl alcohol are added in combination solution obtained by (3), heat preservation
75 DEG C, continue to complete after stirring 30min.
Gained test piece places 18h, observes integrality, the transparency of rust-preventing film after antirust of the present invention smearing, equal with film
Even, transparent, edge ungauged regions are qualification.Rustless property of the present invention detection uses two methods: (1) brine soaking experiment, will be at
It is 15~25 DEG C of temperature in 3%NaCl solution that film sample, which is soaked in mass fraction, and the time of rusty stain occurs in record.(2) neutral salt
Mist test: the NaCl solution that spraying medium is 3%, using continuously spraying mode.
Using silicate as host agent in the present invention, silicate good water solubility is suitble to prepare water-based antirust, can be in steel
Surface forms deposition film, and favorable rust preventing effect is nontoxic, does not generate harmful substance to environment, and defect is that unevenly, there is gap,
Poor water resistance.
In order to solve the defect for the antirust agent that silicate is host agent preparation, phytic acid and Polysucciuimide are added as addition
Agent improves the shortcomings that host agent forms a film.Phytic acid is a kind of Nantural non-toxic product extracted from cereal crops, has extremely strong chelating
Property, phytate molecule, which contains, to be a kind of rare metal with 24 oxygen atoms, 12 hydroxyls and 6 phosphates of metal combination
Chelating agent can form stable complex with metal, when handling metal surface with plant acid solution, easily form one in metal surface
The fine and close unimolecule protective film of layer can effectively organize oxygen to reach metal surface and reduce sky to inhibit corrosion of metal
Gap after compounding with silicate, effectively makes silicate film forming crosslinked together, becomes a similar netted protective film；
Moreover, Polysucciuimide is a kind of biodegradable environmental protection as a kind of novel non-phosphorus water chemical treatment agent
There is polar group to be adsorbed in metal surface, change the structure of electric double layer, improve the activation energy of metal ionization for type corrosion inhibiter,
Non-polar group then makees oriented alignment far from metal surface, forms one layer of hydrophobic membrane, becomes the barrier of corrosion reaction object diffusion, suppression
Corrosion reaction processed, the shortcomings that being effectively improved host agent poor water resistance, while Polysucciuimide and phytic acid as organic matter, cooperation make
With can also generate additional reinforcing effect.
The antirust solution of single component is often extremely difficult to preferable rust-proof effect, and when Multiple components compounding, due to existing
Synergistic effect, it is often more preferable than certain antirust agent effect is used alone.
Polyethylene glycol and polyvinyl alcohol can promote the formation of rust-preventing film as macromolecule film former, make antirust agent firm attachment
In metal surface, to improve the rust-proof effect of antirust agent, the film forming agent as water-based antirust must have can be dissolved in water, at
The uniform condition of film.
