Abstract

The invention discloses a nano-titanium dioxide modified electrophoretic resin and an electrophoretic paint with high plumpness, antibacterial and antiviral properties, and belongs to the technical field of surface coating. The nano-titanium dioxide-modified polyurethane resin comprises the following chemical components in mass percent: hydroxyl functional group-containing polyurethane resin: 10-25%, nano-titanium dioxide: 45-65%, propylene glycol: 3-15%, and the balance is deionized water. The nano-titanium dioxide-modified polyurethane resin is used as one of the reaction raw materials to prepare an electrophoretic resin. The electrophoretic resin has a good surface color and has a certain antibacterial and antiviral ability. Continue to mix the electrophoretic resin with blocked isocyanate, propylene glycol phenyl ether and ethylene glycol butyl ether, and then forcefully shear in water to form an electrophoretic film to obtain an electrophoretic paint. The electrophoretic paint is not only bright and full in surface color, but also has a relatively Good electrical conductivity and antibacterial ability.

Description

[0001] The invention relates to an electrophoretic paint, which belongs to the technical field of surface coating, in particular to a nano-titanium dioxide modified electrophoretic resin and an electrophoretic paint with high plumpness, antibacterial and antiviral properties. Background technique [0002] Cathodic electrophoretic coatings are being applied in industry and developing rapidly, especially the emergence of polyurethane electrophoretic coatings, which exhibit excellent weather resistance and film surface effects, making electrophoretic coatings more and more closely related to human life. However, traditional polyurethane coatings have insufficient plumpness and cannot demonstrate the effect of anti-bacterial technology. In recent years, nano-materials with special functions are usually chosen to be introduced into polyurethane electrophoretic coatings to obtain polymer composites with improved performance, which provides a broader path for the application of polyur...
