Abstract

The invention discloses a mobile phone shell with optical microstructure textures and a processing method. The mobile phone shell is composed of a plastic shell body with the microstructure textures,transparent optical cement, a reflecting film and black glue. Wherein the microstructure texture is a grating microstructure texture of a one-dimensional and two-dimensional periodic array, or one-dimensional gradual change and two-dimensional gradual change grating microstructure texture, or microstructure texture in an annular shape, a spiral shape, a four-side shape, a six-side shape and a polygon shape, or fresnel grains, annular grain microstructure texture and retro-reflection type pyramid prism microstructure texture which has magnification and reduction functions visually; or micro-nano structure component of surfaces of other bionic and imitated articles. The microstructure texture generates a rainbow effect of one-dimensional and two-dimensional distribution, a rainbow effect ofone-dimensional gradual change and two-dimensional gradual change, a curved, spiral, annular and polygonal rainbow effect, a rainbow effect of a star point array, a rainbow pattern visual effect of asimulated article surface and a rainbow holographic effect of a specific pattern.

Description

technical field [0001] The invention relates to the technical field of material production technology, in particular to a mobile phone case with optical microstructure texture and a processing method. Background technique [0002] The 5G era is coming. Compared with the previous 4G and 3G, 5G has a higher transmission frequency and faster signal transmission speed. However, its disadvantages are: due to the high frequency, the diffraction size of obstacles is small, the signal penetration is relatively weak, and the transmission distance is relatively short. Traditional 4G and 3G metal casings are no longer applicable in the 5G era due to the electromagnetic shielding of high-frequency antennas. Mobile phone case materials will undergo a cycle from plastic to metal and back to non-metallic materials (such as plastic, ceramics, and glass casings). At the same time, due to the relatively low cost and high output of plastics, they are favored by the mid-to-low-end market. [...
