Description
Technical field:
The present invention relates to a kind of laurel acidic group hydroxyethyl imidazole quinoline volatile rust preventive material and packing articles field, in particular to
A kind of laurel acidic group hydroxyethyl imidazole quinoline volatile rust prevention fiberboard and preparation method thereof.
Background technique:
In the today in modern industrialization epoch, metal and its product are seen everywhere.But due to the oxygen being widely present in air
The salt contained in gas and water steam, sour gas and vapor, it is easy to atmospheric corrosion occur, generate and aoxidize in metal surface
Object and hydroxide mixture, to damage their performance and reduce its service life, will cause major accident when serious or cause
Equipment scrapping.Especially metal and its product at sea transport and during the overland transport of high fever humidity, are more easier to meet with corruption
It loses and corrodes.According to statistics, the whole world every year due to corrosion caused by economic loss account for 3% or so of current year GDP, about 1/3
Steel because being lost caused by corrosion.Therefore, various metal erosion means of defences cause the concern of people.Currently used smear is prevented
The grease that becomes rusty is owned by France in contact antirust, and not only technique is cumbersome, time-consuming bothersome, ineffective, but also needs to carry out before unpacking
Cleaning by degreasing process easily causes the secondary pollution of environment, and those are not reached with turning, the gap portion of antirust oil
Position, then cannot form effective corrosion protection, this method cannot be increasingly accepted by people.Using vacuum-packing method then at
This is higher, and the extremely difficult reality for large-scale workpiece.Although cost is relatively low for desiccant antirust, easy to use, effectively
Time is shorter and affected by environment larger, effect it is difficult to ensure that.
Vapour phase inhibitor (abbreviation of VCI, Volatile Corrosion Inhibitor) is through special synthesis technology, again
With a kind of corrosion inhibitor made of preparation.It can be independent or depends on suitable carrier, at normal temperatures and pressures direct gasification.?
All fill and contain in any spatial gaps in operation unit by itself adjustable lasting volatilization in sealed environment
There is the mixed gas of the VCI antirust factor, this gas can adsorb thereon when meeting with metal surface, form only one or several points
Sub thick fine and close protective film layer.The protective film layer can effectively completely cut off moisture, oxygen and other hazardous atmospheres and connect to metal surface
The corrosion of touching property, inhibits the electrochemical reaction of metal erosion, to reach optimal anti-corrosion effect.With traditional rust-proofing method phase
Than VCI material has the advantages that many incomparable.Such as after the completion of metal material is packed or is sprayed, vapor phase corrosion inhibitor agent molecule
Just start to dissipate, vapor phase corrosion inhibitor agent molecule may penetrate into the corner space that traditional antirust oil can not cover, and antirust is without dead angle；Gas phase
Inhibition molecule effective component retention time is long, and can extend protective period limit；There are moisture or outside air very moist in metal surface
Under conditions of, corrosion inhibiter, which also can form protecting film in metal surface, prevents rust corrosion.Currently used volatile rust prevention product master
There are volatile rust preventive oil, volatile rust prevention powder, volatile rust preventive paper and gas-phase antirusting film.Volatile rust preventive oil is added by base oil and auxiliary
Agent is added to form, when use needs to smear, time-consuming, labour-consuming when removing protective layer, both unhygienic or dangerous.Volatile rust prevention powder then needs
Use is packed, antirusting powder is scattered and causes damages after bag is damaged.Volatile rust preventive paper toughness is bad, is easy breakage, and
The easy moisture absorption in surface, oil suction cause to pack effect decline, influence antirust function.Although gas-phase antirusting film have it is transparent, flexible,
Processable molding, the features such as barrier property is high, but containing the strong carcinogen nitrous acid disabled in the world in vapour phase inhibitor component
Salt, and vapour phase inhibitor is added directly into blown film in resin, vapour phase inhibitor in technique disclosed in CN01127534.0
Grain is unevenly distributed, and gained membrane product will appear rough surface and analyse white phenomenon；And it is coated with after mixing corrosion inhibiter and bonding agent
In the method on plastic film, then energy consumption is high and complex procedures, can not clean manufacturing, be easy because mix it is uneven due to influences to prevent
Rust effect.
It can thus be seen that developing one kind all has excellent rust-proof effect to a variety of more metals, and with environment friend
Good, volatile rust preventive material easy to operate, to solving the problems, such as that the corrosion of metal for being related to national economy seems especially urgently.Papery is fine
Dimension plate is a kind of from a wealth of sources, degradable inexpensive carrier material, and this material is not easily damaged, and size and shape can be with
Arbitrarily adjustment has very high water absorbing properties, has higher load capacity to volatile rust prevention liquid, it is ensured that prolonged gas phase
Rust-proof effect.It yet there are no the gas-phase rustproof packaging material based on paper fiber, especially yet there are no based on laurel acidic group hydroxyl
The report of the volatile rust prevention papery fiberboard packaging material of ethyl imidazol(e) quinoline and phytic acid compound corrosion inhibitor and preparation method thereof.
Summary of the invention:
