Description of the invention: [Technical field to which the invention pertains] [0001] The present invention relates to a coating and a method of using the same. [Prior Art] [0002] With the development of society and the advancement of science and technology, people's appearance requirements for vehicles, high-end furniture and household appliances are getting higher and higher, and their coatings are required to have both high mechanical properties and high decorative properties. . From the outside, it tends to develop in a transparent, high-color and high-gloss direction; in terms of performance, it requires a certain mechanical strength. [0003] Conventional coatings are composed of a resin and pigment particles doped in the resin. The pigment particles are carbon black or the like, and the particle diameter is usually on the order of micrometers. Taking carbon black as an example, in the coating, generally, carbon black accounts for 5 to 6 wt% of the resin, which has good hiding power. [0004] Carbon Black is a commonly used pigment in the coatings industry. It is a very fine black powdery solid formed by the decomposition or incomplete combustion of hydrocarbons. The main component is carbon. Carbon black has a lamellar network structure with small crystal grains and continuous absorption of all wavelengths including ultraviolet light, so it appears black. [0005] Carbon black is stable in physical and chemical properties, resistant to light, heat, acid, alkali, and oxidation, and is not easily reacted with other substances, and is insoluble in water, oil, and general solvents. [0006] However, pigment particles, such as carbon black, are inorganic substances, and their physical and chemical properties are quite different from those of the resin, resulting in poor solubility and dispersibility in the resin. Generally, it must be mixed with the resin.

Moreover, the combination with the resin is physically combined, and the interaction between the two is weak, and the pigment particles are easily pulled out from the surface of the product to form a cavity. Therefore, the micron-sized inorganic filler causes the mechanical properties of the coating itself to be lowered, and the appearance of the coating is affected. . In view of the above, it is necessary to provide a coating which makes the surface of the product smooth, has high gloss and strong bonding force, and a method of using the same. SUMMARY OF THE INVENTION Hereinafter, a coating material having a smooth surface, a high gloss, and a strong bonding force will be described by way of examples. Further, by this embodiment, a method of using a coating material which is smooth in the surface of the product, high in gloss, and strong in bonding strength will be described. In order to achieve the above, a coating is provided, which is composed of a primer and a topcoat. The main component of the primer is a hydroxylated nano carbon material, and the main component of the topcoat is colloidal ceria, the primer and the primer The topcoat is heated for dehydration polycondensation. And a method of using a coating comprising the steps of: providing a substrate; forming a primer on the surface of the substrate, the main component of the primer being a hydroxylated nano carbon material; forming a side on the primer Paint, the main component of the topcoat is colloidal cerium oxide; heating causes dehydration and polycondensation of the primer and the topcoat. Compared with the coating produced by the prior art carbon black mixed in the resin, the nano carbon material of the embodiment of the invention has a small particle size, which makes the primer smoother.
