The present invention discloses a self-cleaning type high-durability top coat
coating material, which has the following chemical components by
mass: 30-47% of a matrix resin, 3-10% of a cross-linked resin, 0.1-0.3% of an acid catalyst, 25-40% of an inorganic
pigment, 2-6% of a hydrophilic auxiliary agent, 0.3-2% of a lubricating auxiliary agent, 2-7% of an adjusting auxiliary agent, and 10-25% of a
solvent. The present invention further provides a color
coating steel plate, which sequentially comprises a substrate with a plating layer, a pretreatment layer, a front surface prime coat layer, a back surface prime coat layer, a front surface top coat layer, and a back surface top coat layer from outside to inside, wherein the front surface top coat layer is obtained by
coating the self-cleaning type high-durability top coat coating material. According to the present invention, the self-cleaning type high-durability top coat coating material has characteristics of excellent self-cleaning function and high durability; and the color coating steel plate has characteristics of excellent hydrophilicity, good
stain resistance, self-cleaning function, and excellent durability.
