Anticorrosive paint and preparation method thereof.
Background technique
Volatile organic matter (VOC) is the weight of current national air contaminant treatment as one of the major incentive at haze
Point.Traditional solvent type coating is due to largely using volatile organic compounds as solvent, therefore it uses and is more and more restricted.
In face of severe Environmental Protection Situation, country sequentially put into effect policy and regulation guidance coating material production and paint spraying enterprise hydrotropismization,
Environmental-friendlyization such as high solid direction is developed.Currently, water-based anticorrosive paint mainly uses aqueous alkide resin, water soluble acrylic acid
Resin, waterborne polyurethane resin and aqueous epoxy resins are main film forming substance.Wherein water alcohol acid, water-borne acrylic type product
Based on single-component package, in performance under, be mainly directed towards light anti-corrosion application；Aqueous polyurethane, water-base epoxy class product are mostly double
Component packaging, has excellent performance but on the high side, the decoration being mainly directed towards under the medium corrosive environment to severe and protection.
Polyvinylidene chloride (PVDC) resin is by vinylidene chloride (VDC)), acrylonitrile, acrylic acid and esters of acrylic acid
Etc. a kind of resulting barrier property of other monomers polymerization is high, toughness is strong and the good material of chemical stability, with excellent resistance to
Oily, corrosion-resistant, guarantor's taste and oxygen barrier moisture-proof and fungicidal properties.Currently, PVDC resin has been widely used in food, medicine, paper
, cosmetics and military supplies etc. are various needs the barriers such as oxygen barrier anti-corrosion, every flavour guarantors perfume, water proof moisture-proof, oil removal permeation-proof requirement height
Field of product packaging.According to the difference of processing method, PVDC resin is divided into two types: one kind is extrusion, use in injection molding
Resin；Second is that the latex of coating film.In recent years, the lotion based on the synthesis of VDC monomer is free of inflammable and virose solvent,
And film has good oxygen barrier waterproof performance, can substantially reduce corrosion of metal speed, obtain in anti-corrosion of metal field

US4997859, the PVDC lotion in the above-mentioned patent such as European patent EP 0268042 are all using seeded emulsion polymerization producer
Method, conventional emulsion polymerization process are Micellar nucleation mechanism, and monomer needs certain water solubility and migrated by water phase to micella
It just can be carried out polymerization reaction, and solubility of the monomer in water phase is extremely low, affects going on smoothly for emulsion polymerization.Miniemulsion body
Due to the presence of not no micella in system, nucleation can be caused directly in monomer droplet after initiator is added, emulsion polymerization is monomer
Droplet nucleation mechanism, it is poly- for the lotion of vinylidene not soluble in water not against diffusion of the monomer in continuous phase
Great advantage is shown for conjunction.
It is existing done solid work using polyvinylidene emulsions as the water paint of constituent after have preferable dielectric shielding
Performance, low but there are mechanical strengths, the not high problem of the adhesive force to ground, being easily bruised leads to holiday and influences to prevent
Corrosive effect.And the acrylate monomer containing aniline Trimeric structures and vinylidene chloride is used to be copolymerized, in molecular resin
When aniline Trimeric structures and metal base contact, nitrogen-atoms, aryl in molecular structure etc. are containing lone electron pair and delocalization π electricity
The group of son can form stable complex compound by coordinate bond and iron atom and be adsorbed on metal surface, further enhance coating tree
Binding force and adhesive force between rouge and substrate, resin and filler, while aniline tripolymer can react one layer of generation with metal surface
Fine and close oxidative deactivation film improves the antiseptic property of aqueous polyvinylidene dichloroethylene coating to achieve the effect that inhibition.
