Description
Technical field：
The present invention relates to a kind of phytic acid type volatile rust preventive material and packing articles field, in particular to a kind of phytic acid type gas phase
Antirust fiberboard and preparation method thereof.
Background technology：
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 which atmospheric corrosion occurs, generates in metal surface and aoxidizes
Thing and hydroxide mixture, so as to damaging their performance and reducing its life-span, can cause a serious accident when serious or cause
Equipment scrapping.Especially metal and its product are at sea transported during the overland transport moist with hyperpyrexia, are more prone to meet with corruption
Lose and corrosion occurs.According to statistics, the economic loss that the whole world is caused every year because of corrosion accounts for 3% or so of GDP then, about 1/3
Steel because corrosion cause loss.Therefore, various metal erosion means of defences cause the concern of people.Conventional at present smears anti-
Rust grease is owned by France in contact antirust, and not only technique is loaded down with trivial details, take bothersome, effect on driving birds is not good, and also needs to be carried out before unpacking
Cleaning by degreasing operation, easily causes the secondary pollution of environment, and turning, the gap portion for not reaching antirust oil for those
Position, then can not form effective corrosion protection, and this method increasingly can not be received by people.Using vacuum-packing method then into
This is higher, and the extremely difficult reality for large-scale workpiece.Although drier antirust cost is relatively low, 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 the special synthesis techniques of Jing, answers
With a kind of corrosion inhibitor being prepared from.It individually or can depend on suitable carrier, at normal temperatures and pressures direct gasification.
Cause in any spatial gaps in operation unit, can all fill and contain by itself adjustable persistently volatilization in sealed environment
There are the mixed gas of the VCI antirust factors, this gas can adsorb thereon when meeting with metal surface, form only one of which or several points
Sub thick fine and close protection film layer.The protection film layer can effectively completely cut off moisture, oxygen and other hazardous atmospheres and metal surface is connect
Tactile property corrosion, suppresses the electrochemical reaction of metal erosion, so as to reach optimal anti-corrosion effect.With traditional rust-proofing method phase
Than VCI materials have many unrivaled advantages.Such as after the completion of metal material is packed or sprayed, vapor phase corrosion inhibitor agent molecule
Just diverging is started, vapor phase corrosion inhibitor agent molecule may penetrate into the corner space that traditional antirust oil cannot be covered, and antirust is without dead angle；Gas phase
Inhibition molecule active ingredient 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 also can form protecting film and prevent rust corrosion in metal surface.The volatile rust prevention product master for commonly using at present
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
Plus agent composition, when using need smear, remove overcoat when it is time-consuming, take a lot of work, it is both unhygienic or dangerous.Volatile rust prevention powder is then needed
Pack and use, antirusting powder is scattered and causes damage after bag breakage.Volatile rust preventive paper toughness is bad, easy breakage, and
The easy moisture absorption in surface, oil suction, cause to pack effect decline, affect antirust function.Although gas-phase antirusting film have it is transparent, flexible,
Can machine-shaping, the features such as barrier is high, but containing the strong carcinogen nitrous acid for disabling in the world in vapour phase inhibitor component
Vapour phase inhibitor is added directly into into blown film in resin, vapour phase inhibitor in salt, and technique disclosed in CN01127534.0
Grain skewness, gained membrane product occurs rough surface and the white phenomenon of analysis；And will be coated with after corrosion inhibiter and bonding agent mixing
Method on plastic sheeting, then energy consumption is big and complex procedures, can not clean manufacturing, easily affects to prevent because mixing uneven
Rust effect.
It can thus be seen that developing a kind of all with excellent rust-proof effect and friendly with environment to various many metals
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 particularly urgent.Papery is fine
Dimension plate is that a kind of wide material sources, degradable inexpensive carrier material, and this material do not allow cracky, and size and dimension can be with
Arbitrarily adjustment, with very high water absorbing properties, has higher load capacity to volatile rust prevention liquid, it is ensured that prolonged gas phase
Rust-proof effect.Yet there are no based on the gas-phase rustproof packaging material of paper fiber, especially yet there are no slow based on phytic acid compounding
The report of the volatile rust prevention papery fiberboard packaging material of erosion agent and preparation method thereof.
