Belong to antirust field to be widely used.Conventional gas-phase rust inhibitor formulation mostly contains the component such as sodium nitrite, organic amine salt,
In use it is easily formed this strong carcinogen of inferior ammonium nitrate.In recent years, both at home and abroad in terms of finding nitrite succedaneum
Carry out many useful explorations, and achieved some achievements, as CN201410629461.5 discloses Palmic acid diethanol acyl
Amine borate gas-phase anti-rust master batch and its preparation method and application, CN201210158582.7 discloses with molybdate, SA
Salt is the gas-phase anti-rust master batch of main composition, and the inactivating performance of these antirust agent and nitrite gap are relatively big, the most not yet
Find the preferable substitute materials of nitrite.
Polyaniline is a kind of new functional macromolecule material, has good heat stability, chemical stability and excellent
Chemical property, raw material is easy to get, cheap, and synthesis technique is easy, also has the advantages such as unique doping phenomenon.With conventional inhibition
Agent such as chromate, molybdate etc. are compared, and polyaniline does not has any environment side effect, are a kind of to meet epoch and development in science and technology
Green corrosion inhibitor.But at present, polyaniline is mainly used in anticorrosive coating, and using it as additive at vapor phase inhibitor technology
Aspect yet there are no and relates to, and especially yet there are no about the gas-phase anti-rust master batch with polyaniline, organic amine salt as compound corrosion inhibitor and prevents
The preparation method report of rust plastic sheeting.
