Embodiment Construction
[0045] The present invention will be described in detail below in conjunction with specific embodiments, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.
[0046] Prepare the anti-graffiti electrophoretic paint according to the ratio of Table 1, and the composition of each embodiment remaining ratio in the table is water;
[0047] Table 1:
[0048]
[0049]
[0050] The electrophoretic paints prepared in the above-mentioned examples were respectively used, the electrophoretic parameter voltage was set to 50V, and the electrophoresis time was 200s. After electrophoresis, the coated conductive substrate was removed, and the excess electrophoretic paint was rinsed with clean water. Dry to make it cross-linked to form a film.

The invention discloses anti-doodling electrophoretic paint. The anti-doodling electrophoretic paint is prepared from high hydroxyl value water-soluble fluorine-silicon cationic resin, a closed curing agent, a coalescing agent, pigment, cosolvent and water. A using method of the electrophoretic paint comprises the steps that an electrophoresis process is adopted for conducting surface coating on a metal substrate with a conduction property, drying is conducted on the coating, and film is formed through crosslinking. The anti-doodling electrophoretic paint has the advantages that the anti-doodling property is good, adhesion, wear resistance and transparency are excellent, and very good isolation and protection effects on the metal substrate can be achieved.
Description
