A method of directly transferring molded textures or patterns onto tempered glass

Abstract

The invention discloses a method for directly transferring mold textures or mold patterns on tempered glass. The method comprises the following steps that 1, the washed tempered glass is placed on an arrangement jig; 2, a UV photo-sensitive resist is smeared on the surface of the tempered glass; 3, a textured mold or a patterned mold is attached to the surface, coated with the UV photo-sensitive resist, of the tempered glass; 4, the tempered glass covered with the textured mold or the patterned mold is rolled; 5, the tempered glass obtained in the step 4 is subjected to ultraviolet exposure in an ultraviolet curing machine; 6, the tempered glass is separated from the textured mold or the patterned mold; 7, the tempered glass with the textures or the patterns is put into a cleaning machine for unexposed or overflowed UV photo-sensitive resist cleaning; and 8, the cleaned tempered glass with the textures or the patterns is put into the ultraviolet curing machine for ultraviolet irradiation and curing. The preparation method has the advantages that the prepared textures or the patterns are small in thickness, the light and shadow effect of the product is good, the technological process is easy to implement, and the product yield is high.

Description

technical field [0001] The invention relates to the technical field of camera window lenses and fingerprint identification glass cover plates, in particular to a method for directly transferring mold textures or patterns to tempered glass. Background technique [0002] With the continuous development of mobile phones, the camera function of mobile phones has become the main selling point, and high pixel and dual cameras have increasingly become the focus of publicity. Therefore, mobile phone manufacturers have tried every means to increase the decorative effect in the design of the camera protection window, for example, by designing a CD texture on the camera protection window to highlight the selling point of the camera. The existing decoration process is to transfer the texture to the PET film first, then do coating, silk screen printing, cutting and other processes on the film, and then attach the film to the tempered glass. This process has defects such as complicated p...

This process has defects such as complicated process, thick diaphragm, high product yield and low cost, and partial deformation of product texture under pressure.

[0003] The Chinese invention patent application with the publication number CN106398382A discloses a sublimation glass and its preparation method. The preparation method includes sequentially covering the surface of the tempered glass with a primer, a printing film, a hydrophilic material layer, and a thermal transfer printing ink. , and finally prepare the printed tempered glass by thermal sublimation in a thermal transfer machine. The preparation of the present invention uses a thermal transfer ink with complex chemical formula, and the prepared printed tempered glass has a thicker printing thickness and a more cumbersome preparation process.
