Abstract
A high-adhesion and low-thickness nano-class finish paint for high-grade automobile is prepared from nano-class powder of Ti, Ni, Al, or diamond through mixing with amorphous carbon powder, coating with coupling agent, and proportionally adding it to the acrylic-type, polyurethane-type, or acrylic-polyurethane paint of automobile. Its advantages are high hardness, adhesion, weatherability, lustre and antiwear and anti-impact performance.
Description
Technical field: [0001] The invention relates to a metal finish, in particular to a high-strength, low-hiding-thickness, high-end automotive nano finish and a production method thereof, belonging to the technical field of metal coatings. Background technique: [0002] Usually in the metal topcoat paint, by adding infusible and insoluble inorganic and organic fillers to the polymer material, it can improve the rigidity, toughness and wear resistance of the polymer block material. It can also improve the adhesion between the polymer coating and the substrate. For example, the resin is filled with fine-grained powders such as oxides, calcium carbonate, metals, carbon black, etc. (the particle size is generally on the order of micrometers) or glass fibers. Although the former can improve the hardness and wear resistance of polymer materials to a certain extent, and improve the adhesion to inorganic matrix to a certain extent, it makes the polymer materials brittle, and even some fill...
