5. the preparation method of a kind of water-based anticorrosive paint described in claim 1,2,3 or 4, it is characterised in that including following step
Suddenly：
Each reactive material is weighed according to parts by weight, wetting is added in control rotating speed 1500-2500r/min high speed dispersor
Agent, levelling agent, defoamer, corrosion inhibiter and color stuffing, water-base resin is added in high speed dispersor, in control rotating speed 300-
Wetting agent, levelling agent, defoamer, thickener, coalescents and deionized water are added under 400r/min, is turned through 600-800r/min
Rotating speed is down to 300r/min after the lower scattered 15-20min of speed, hydrophilic modifying aliphatic polymeric isocyanate curing agent and catalysis is added
Agent, continues scattered 5-10min, and through being filtered to remove filter residue after being well mixed, the filtrate of gained is again 25- through mass percent concentration
28% ammoniacal liquor adjusts pH value to be 8-9, that is, obtains water-based anticorrosive paint.
6. a kind of preparation method of water-based anticorrosive paint according to claim 5, it is characterised in that：Described water-base resin
Preparation method be by 60-70 parts of active phosphate monomers, 60 parts of chlorinated polyether resins, 0.07 part of MEHQ and diethylene glycol
Dimethyl ether, propylene glycol monomethyl ether, butanol mixed solvent are added in flask with four necks,round bottom, are heated and are stirred, are warming up to 100 ~ 120 DEG C
And chlorinated polyether resin is when being completely dissolved, 60 parts of acrylate monomers, 10 parts of neopentylglycol diacrylates, described acrylic acid are added
It is 10 in mass ratio by acrylic acid, methyl acrylate, n-butyl acrylate, 2-Hydroxy ethyl acrylate that ester monomer, which is,:10:10:
The mix monomer of 3 compositions, after addition is finished, is warming up to 110 ~ 120 DEG C of reactions, the lower 3 ~ 4h of constant temperature of stirring stops heating, treats temperature
40 ~ 50 DEG C are dropped to, regulation pH value is 7, add deionized water and quickly stir, 1 ~ 2h of constant temperature, remove solvent through decompression, produce water
Property anticorrosive paint water-base resin.
7. a kind of preparation method of water-based anticorrosive paint according to claim 6, it is characterised in that：Described vacuum distillation
Process control temp is 30 DEG C, and pressure is -755mmHg.
