Abstract

An optical colorful film and a manufacturing method thereof, the method comprising: S1, depositing a TiO2 layer on the surface of a base material as a first layer; S2, depositing a SiO2 layer on the first layer as a second layer; S3, depositing a SiO2 layer on the first layer; Depositing a TiO layer on the second layer as the third layer; S4, depositing a SiO layer on the third layer as the fourth layer; S5, depositing a TiO layer on the fourth layer as the fifth layer; S6, depositing the TiO layer on the fourth layer as the fifth layer; Depositing a SiO2 layer on the fifth layer as the sixth layer; S7, depositing a TiO2 layer on the sixth layer as the seventh layer; wherein, controlling the deposition process of the multilayer film makes the multilayer film produce dazzling color, and continuously deposit the seventh layer, that is, the outermost layer, for 40 to 50 minutes while maintaining the dazzling color. The invention greatly improves the wear resistance of the optical film, and at the same time ensures the colorful effect of the optical film.

Description

technical field [0001] The invention relates to the field of optical films, in particular to an optical colorful film and a manufacturing method thereof. Background technique [0002] The preparation technology of optical thin films is to deposit thin film materials into thin films according to certain technical approaches and specific requirements. With the development of modern information optics, optoelectronic technology and photon technology, the requirements for long life, high reliability and high strength of optical thin films are getting higher and higher, thus a series of new optical thin films and their preparation technologies have been developed. These technologies are used in the preparation of optical thin films, which not only greatly broadens the range of materials available for optical thin films, but also greatly improves the performance and functions of optical thin films. Optical thin films can be prepared by physical vapor deposition (PVD), chemical va...
