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, lustreand antiwear and anti-impact performance.

Description

Technical field: [0001] The invention relates to a metal topcoat, in particular to a high-strength, low-coverage high-grade nano-topcoat for vehicles and a production method thereof, belonging to the technical field of metal coatings. Background technique: [0002] Usually, adding non-melting and insoluble inorganic and organic fillers to the polymer materials in metal topcoat coatings can improve the mechanical properties of the polymer block materials such as rigidity, toughness and wear resistance. It can also improve the adhesion between the polymer coating and the substrate. For example, fine-grained powders such as oxides, calcium carbonate, metals, and carbon black (generally in the micron range) or glass fibers are added to the resin. Although the former can improve the hardness and wear resistance of the polymer material to a certain extent, and improve the adhesion with the inorganic matrix to a certain extent, it makes the polymer material brittle, and even some ...
