Description
Technical field
The invention belongs to technical field of coatings, more particularly to a kind of preparation method of water-based anticorrosive paint.
Background technology
Truck drive shaft is tubular type carbon steel material, and workpiece surface is typically handled using ferric solid-acid.Therefore film corrosion resistant
Corrosion is relatively difficult up to standard, meanwhile, workpiece surface is often with certain corrosion point.Because workpiece weight, thickness are high, heat transfer and radiating phase
To relatively slow, corrosion resistance, drying property and the offline dry-ness key technology that can be used as water paint of coating.Automobile
Most of power transmission shaft application factory uses disk electrostatic spraying technique, and disposable application thickness is up to 50~60 μm, solidification temperature
For 80 DEG C, 30min.State's intermediate solid drive shaft application at present mainly based on solvent borne polyurethane system and two-component epoxy system, is produced
Product construction pot-life is short, loss is high, serious inflammable and explosive danger be present, VOC emission is high, has a strong impact on that the body of spraying workman is good for
Health.Therefore, truck drive shaft application is badly in need of developing to environmental protection, low-carbon direction.
The content of the invention
The technical problems to be solved by the invention are just to provide a kind of preparation method of water-based anticorrosive paint, solve existing
The technical problem of truck drive shaft anticorrosive paint not environmentally.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of preparation method of water-based anticorrosive paint,
Comprise the following steps：
1) 200-250 part waterborne acrylic modified alkyd resins are added in agitator, 5- is sequentially added under stirring
10 parts of DMEA, 15-20 part drier, stir, and are slowly added to 15-20 part deionized waters, are stirring evenly and then adding into 10-15 points
Powder, 1-5 defoamers, after fully dispersed 10min, put into order 60-100 parts rust resisting pigment, 200-250 parts paint filler and
1-5 part attapulgites, after stirring 15min, it is transferred to sand mill and is ground to fineness less than 15 μm；
2) 50-100 part self-crosslinking acrylic emulsions are added in the solution 1) obtained, are then added under conditions of stirring
10-20 part aqueous color pastes, 2-5 parts wetting agent, 10-15 parts anti-flash corrosion inhibitor, the thickening thixotroping of 10-15 parts are finally added in sequence
Agent, 100-150 part deionized waters, stir, and are finally more than 8.0 with 5-10 parts DMEA adjustment pH value, stand 20~30min
Afterwards, water-based anticorrosive paint is made with 300 mesh sieve net filtrations.
Beneficial effects of the present invention are：With water-based acrylic acid modified alcoholic acid matrix resin, it is aided with the propylene yogurt of self-crosslinking
Liquid is to dry accelerator, and with reference to the antirust color stuffing and function additive of asepsis environment-protecting, the water-based anticorrosive paint prepared can be applied
In truck drive shaft application, the product low-temperature setting, suitable for the execution conditions of existing solvent based coating paint line, energy-saving ring
Protect, meet the needs of enterprise safety operation.Film has good physicochemical property, corrosion resistance Canon, effectively solves automobile and passes
Moving axis disc type electrostatic spraying pattern, product combination property reach solvent borne polyurethane coating property index.The exploitation of the product
Be advantageous to traditional truck drive shaft paint industry to environmental protection direction to develop.
