4. the preparation method of the long-acting weather-resistant type anticorrosive paint water-base resin described in claim 1, it is characterised in that including such as
Lower step:Functional fluoropolymer monomer, chlorinated polyether resin, epoxy resin, polymerization inhibitor and solvent are added in a reaction vessel, heated
And stir, it is warming up to 100-110 DEG C and when functional fluoropolymer monomer is completely dissolved, adds acrylate monomer, modified crosslinking monomer
After mixed solution, completion of dropping, 115-120 DEG C or so reaction is warming up to, the lower h of constant temperature 3 ~ 5 of stirring stops heating, treats temperature
40 ~ 50 DEG C are dropped to, regulation pH value is 7 ~ 8, add deionized water and quickly stir, the h of constant temperature 0.5 ~ 2 produces long-acting weather resistant
Anticorrosive paint water-base resin.
