Conventional products.
The present invention provides a kind of anti-corrosive primer, the component including following mass percentage:
Modified resin has polyfunctionality, forms higher degree of crosslinking with plant acid, fluororesin by multifunctional, is passivated
Film, and stabilization is attached to metal surface, prevents the rust of metal base.
Anti-corrosive primer includes the component of following mass percentage in one of the embodiments:
In one embodiment, modified resin is modified epoxy, is generated using the functional group of epoxy resin multi-faceted
Crosslinking forms high-crosslinking-degree with plant acid, fluororesin etc., obtains the stable passivating film of performance, and with tackifier and thickener
Joint obtains good adhesive force, guarantees the long-term effect of anti-corrosive primer.More preferably, modified resin is novolac epoxy resin, phenol
Formaldehyde epoxy resin is made of bisphenol A type epoxy resin and phenolic resin, can form the modified epoxy of polyfunctionality, have compared with
The high degree of cross linking makes it have higher heat distortion temperature and excellent thermostabilization simultaneously because there are a large amount of phenyl ring in skeleton
Property, and this performance is introduced into anti-corrosive primer, increase the practicability of anti-corrosive primer.
In one embodiment, plant acid is selected from one or more of gallic acid, p-Coumaric Acid and caffeic acid.Galla turcica
Acid, p-Coumaric Acid and caffeic acid are polyhydroxy plant acid, can be crosslinked, be stablized by hydroxyl and carboxyl and modified resin generation
Cross-linked scaffold, and become rusty with metal and generate complex reaction, convert a part of film for metal rust.
In one embodiment, fluororesin is aqueous fluorocarbon resin, increases the water resistance, weatherability and tear-proof of anti-corrosive primer
Property.More preferably, fluororesin selects fluororesin 23-19, and solid content is 48 ± 3%, fluorine content >=9%.
In one embodiment, tackifier are aqueous rosin tackifier, and commercially available aqueous rosin Tackified emulsion can be selected, admittedly contain
Amount is 50%~60%, Brookfield viscometer (3#, 60RPM, 25 DEG C) 500~1200mPa.S.
