AI Technical Summary

Problems solved by technology

The existing film-forming resin system makes the added nano-aluminum powders generally arranged in a disordered state, making it difficult to spread the metal particles on the substrate, resulting in a disorderly arrangement of the metal particles and forming diffuse reflection when the light hits the surface. Can't get mirror effect

Abstract

The invention discloses mirror ink, which is characterized by comprising the following components in percentage by mass: 20 to 40 percent of polyving akohol binary copolymer, 30 to 45 percent of cyclohexanone, 1 to 3 percent of wetting agent, 15 to 30 percent of nano-aluminum powder and 2 to 10 percent of butyl cellosolve. The components are added into a vacuum stirrer for uniform stirring, and are filled and packaged. The mirror ink has the advantages of good mirror effect and strong decoration, and can be widely used for decorating mobile phones, notebook computers and household appliances.

Description

technical field [0001] The invention belongs to the field of ink, and more specifically relates to a specular ink. The ink can be used in household appliances, mobile phones, automobile dashboards and other fields, and its characteristics are suitable for surface in-mold decoration technology matched with IMD technology. Background technique [0002] With the development of IMD technology, in addition to requiring the decorated surface to have rich colors and three-dimensional effects, it is also required that the surface have a mirror effect. The existing film-forming resin system makes the added nano-aluminum powders generally arranged in a disordered state, which makes it difficult to spread the metal particles on the substrate, resulting in a disorderly arrangement of the metal particles and forming diffuse reflection when the light hits the surface. Unable to get mirror effect. Contents of the invention [0003] The purpose of the present invention is to addre...
