Problems solved by technology

Since nanomaterials are fine particles that cannot be seen by ordinary microscopes, and their surface activity is quite high, after the current nanomaterials are added to the base material to prepare a coating, the nanomaterials are prone to further agglomeration, flocculation, and dispersion instability.

Abstract

The invention discloses a nano-titanium dioxide automobile topcoat coating. The nano-titanium dioxide automobile topcoat coating is characterized by being prepared from the following raw materials in parts by weight: 55-70 parts of titanium dioxide slurry, 8.5-21.4 parts of nano-titanium dioxide slurry, 6-8 parts of polar resin, 0.2-0.4 part of a flatting agent and 15-20 parts of a dispersing agent, wherein the nano-titanium dioxide slurry comprises the following components in percentage by mass: 88 percent of hydroxy acrylic resin, 7 percent of nano-titanium dioxide, 2 percent of dimethylbenzene, 2.6 percent of butyl alcohol and 0.4 percent of butyl acetate; the particle diameter of the nano-titanium dioxide is 65-130 nanometers; the dispersing agent is the combination of butyl alcohol, butyl acetate and dimethylbenzene. By adopting the coating, the agglomeration, flocculation and dispersion of titanium dioxide are avoided, and stable ultraviolet resistance, high hardness and high compactness are realized.

Description

technical field [0001] The invention relates to an automobile coating, in particular to a nano-titanium dioxide automobile topcoat. Background technique [0002] Paint coating is one of the main processes in the manufacture of automobiles and motorcycles. It plays a decorative and protective role and can improve the grade of products. With the rapid development of automobiles and motorcycles at home and abroad and the entry of WTO, product competition is increasingly intensified. All manufacturers are improving and innovating in quality, variety, shape, and appearance. The innovation and paint film of the overall appearance and decoration of automobiles and motorcycles The improvement of service life is particularly important to increase the competitiveness of products. [0003] At present, the appearance of the existing automobile paint film is exposed to sunlight and ultraviolet rays. After a period of use, the appearance of the paint film will produce aging phenomena suc...
