Abstract
The invention relates to electrophoretic paint. The electrophoretic paint comprises at least one water-dispersible cationic group-containing organic base material. A lanthanide rare earth element is used in the cathodic electrophoretic paint, and the weight of the lanthanide rare earth element is 0.001-0.01% solid weight of the cathodic electrophoretic paint. The electrophoretic paint can be prepared by simple processes, has strong adhesion, forms a uniform film, can be cure fast after coating, does not form pits on the workpiece surface after curing and greatly improves workpiece corrosion resistance.
Description
Technical field
The invention belongs to paint field, be specifically related to a kind of electrocoating paint.
Background technology
The throwing power of throwing power cathode electro-coating is exactly under the effect of electric field, electrocoating paint deviates from the coating ability at the position (place such as workpiece lumen, concave surface, gap) of anode to coated article, that is make the workpiece all surfaces of structural shape complexity coat the ability of paint film uniformly.The height of throwing power affects the preservative property on complex part surface.Electrocoating paint film is efficient, can carry out even application, but often can form pit to less gap and irregular workpiece, and the precision of impact spraying, reduces the Corrosion Protection of workpiece after spraying.
Summary of the invention
The object of this invention is to provide a kind of electrocoating paint, greatly can improve the smooth finish of workpiece surface after cathode electrophoretic coating.
The present invention is achieved through the following technical solutions:
A kind of electrocoating paint, comprises that at least one is dispersible in water, organic base-material containing cation group, and in cathode electrodip painting, add lanthanide series rare-earth elements, lanthanide series rare-earth elements add-on is the 0.001-0.01% of the solids content weight of cathode electrodip painting.
Preferably, cathode electrodip painting is epoxy coating; Epoxy coating is zinc yellow epoxy primer.
Preferably, the PH of cathode electrodip painting is 5-6.
Preferably, the specific conductivity of electrocoating paint is 1620 ± 120us/cm.
Beneficial effect of the present invention: electrocoating paint compound method provided by the invention is simple, the electrocoating paint strong adhesion obtained, film forming is even, at the attached quick solidifying of Tu, can not form pit after solidification at workpiece surface, substantially increase the antiseptic property of workpiece.
Embodiment
A kind of electrocoating paint, comprises that at least one is dispersible in water, organic base-material containing cation group, and in cathode electrodip painting, add lanthanide series rare-earth elements, lanthanide series rare-earth elements add-on is the 0.001-0.01% of the solids content weight of cathode electrodip painting.
Preferably, cathode electrodip painting is epoxy coating; Lanthanide series rare-earth elements add-on is 0.0075% of the solids content weight of epoxy coating.
Preferably, the PH of cathode electrodip painting is 5-6.
Preferably, the specific conductivity of electrocoating paint is 1620 ± 120us/cm.
Epoxy coating is used to be zinc yellow epoxy primer at negative electrode, lanthanide series rare-earth elements add-on is 0.0072% of the solids content weight of cathode electrodip painting, during to steel plate cathode electrophoretic coating, cathode electrodip painting PH is 5.8, specific conductivity is 1700 ± 20us/cm, electrophoretic voltage 220V, time 25-30s, during solidification, curing oven temperature is 168 ± 2 DEG C, set time 10-12min, electrophoresis chamber temperature 28 ± 2 DEG C, electrophoresis and set time all shorten, and improve electrophoresis efficiency, and after process, surface of steel plate is even, without pit, substantially increase the Corrosion Protection of surface of steel plate.
