Abstract

The invention discloses a reflective grating gradient explosion-proof membrane and a preparation method thereof. The explosion-proof membrane comprises an ink layer, a reflecting layer, a UV structurelayer, a PET explosion-proof membrane layer and a multi-color printed layer, which are sequentially arranged from top to bottom, wherein the ink layer is formed by printing through screen printing equipment, the reflecting layer is formed by coating through a coating machine, the UV structure layer is formed by UV glue photo-curing, the UV structure layer is of a lenticular grating structure, andthe multi-color printed layer is formed by printing through a high-precision printing machine. According to the provided reflective grating gradient explosion-proof membrane, the patterns of the multi-color printed layer are subjected to a blending treatment by utilizing the lenticular grating structure of the UV structure layer, and natural gradient among multiple colors can be presented, so that the explosion-proof membrane with gradient colors is obtained. The preparation process of a traditional explosion-proof membrane is not changed, so that industrial mass production is facilitated, and the production rejection rate is reduced. On the other hand, due to the arrangement of the lenticular grating structure, the gradient colors have good consistency.

Description

technical field [0001] The invention relates to the technical field of explosion-proof membranes, in particular to a reflective grating gradient color explosion-proof membrane and a preparation method thereof. Background technique [0002] Now the 3C industry market is developing rapidly, especially in the mobile phone industry. The glass back cover of mobile phones is widely used. The relatively high-end models all have micro-nano texture or high-reflective texture. The market demand presents various diversity. There are pure texture structures. , There are also reprocessed textures designed in the later stage. After market evolution, mobile phones with gradient effects are more attractive to customers. The production of gradient effects is complicated. It is understood that there are several processes for producing gradient colors: 1. Micro-filling method. When making molds, a micro-lattice structure is reserved on the surface of the mold through two processes, and then I...
