The invention discloses a black top paint with high blackness and blue phase, and a preparation method thereof. The top paint is composed of the following components by weight: 55-75 parts of a hydroxyl acrylic resin, 10-15 parts of a hydroxyl polyester resin, 0.25-0.55 parts of a leveling agent, 1.5-4.0 parts of a light stabilizer, 2.0-3.0 parts of high coloring carbon black, 2.0-3.0 parts of a wetting dispersant, 0.2-0.4 part of a synergistic dispersant, 0.03-0.05 part of a catalyst and 12-16 parts of a solvent. The black top paint with high blackness and blue phase is compounded by the hydroxyl acrylic resin, the hydroxyl polyester resin and a plurality of auxiliary agents, and has the advantages of excellent overcoatability, good leveling property, good weather resistance, good hardness and good scratch resistance. Compared with conventional black top paint, the black top paint provided by the invention has high blackness, high blue phase, high glossiness, high distinctness and high fullness, and can meet requirements for high-grade black top paint by coating and repairing in car and automobile industries.
