According to the formulation described in the above embodiment, the raw materials are mixed according to the quality parts, and the mixture is uniformly stirred to obtain the lacquer according to the present invention. The lacquer of the present invention is coated on an aluminum light plate or other metal plate and applied to the surface of the metal plate to form a wet layer. The film has a wet film thickness of 100-110 micrometers (μm), and is heated at 170-180 ° C for 3-5 minutes to form a dry film. After the dry film is formed, it shrinks and wrinkles to form a shape such as crystalline ore. The visual effect is very good, and the obtained dry film is formed with uneven wrinkles, and the thickness is 20-160 micrometers (μm), the dry The film can also be formed into a variety of different shapes of patterns, combined with the glossy reflection of the metal plate, is simply a visual enjoyment.

The reason for the formation of the coating film was analyzed by using two different hydroxyl (-OH) acrylic resins, two polyisocyanate resins containing isocyanate (-NCO) groups, and two hydroxyl groups (-OH). ), ether-based (-OR) methylated melamine formaldehyde resin, with a small amount of polyester resin, and several catalysts added, after heating and drying after coating, the resin contains hydroxyl (-OH), carboxyl (-COOH) ), amidino group (-CONH ₂ ), the functional group curing reaction phase is different, resulting in different drying and shrinking time of the inner layer and surface of the coating film, causing the coating film to wrinkle to form an irregular pattern.

In summary, the present invention has the following effects as compared with the prior art decorative coatings: after the coating forms a coating film on the metal plate, the surface is formed with wrinkles, thereby having a special multi-directional three-dimensional texture, which is unevenly curved and appears different. The shape of the pattern, and the addition of color paste, the bright color, with the luster of the metal plate substrate, showing different reflection effects, the visual effect is very significant, giving a strong visual enjoyment, overcoming the existing decorative plate texture Monotonous, dim color defects.
