Embodiment Construction

[0019] Anti-scratch protective varnish printing process, consisting of the following steps:

[0020] A) Screen-print a layer of UV glass CNC cutting protection ink before the white sheet is cut, and the UV glass CNC cutting protection ink is composed of the following substances by weight percentage:

[0021] Epoxy resin 44-46% Barium sulfate 14-16% Talc powder 10-12% Silicon dioxide 0.5-1.5% Phthalocyanine green 1-2% Photoinitiator 5-6% Ester solvent 20-22%;

[0022] B) After step A, carry out glass protection, and completely bake and dry the ink on both sides of the glass to protect the original appearance of the glass incoming material, and then carry out material cutting, profiling, trimming, slotting, groove repairing, The steps of CNC, stripping, pre-cleaning, strengthening, post-grinding, and post-cleaning.

[0023] The processing steps of the UV glass CNC cutting protective ink are:

[0024] Mix together the ingredients in the step;

[0025] Stir thoroughly with a mi...

Abstract

The invention belongs to the technical field of manufacture of photoelectron devices, and particularly relates to a pre-processing working procedure for glass of white panels. A layer of UV (ultraviolet) glass CNC (computerized numerical control) cutting protecting printing ink is in screen printing before cutting of a blank sheet. The UV glass CNC cutting protecting printing ink consists of substances including, by weight percentage, from 44 to 46% of epoxy resin, from 14 to 16% of barium sulfate, from 10 to 12% of talcum powder, from 0.5 to 1.5% of silicon dioxide, from 1 to 2% of phthalocyanine green, from 5 to 6% of photoinitiator, and from 20 to 22% of esters solvent. Glass is protected after a step A, printing ink on two surfaces of the glass is baked and dried thoroughly, and an original appearance effect of the glass is protected, and then steps including cutting, profiling, trimming, grooving, groove trimming, CNC, demolding, previous cleaning, strengthening, subsequent grinding and subsequent cleaning are realized successively.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic device manufacturing, and in particular relates to the pre-processing and manufacturing process of white panel glass. Background technique [0002] As white panel glass is widely used in electronic devices such as mobile phones, digital cameras, notebooks, touch screens, etc., and the market demand for this panel is in short supply, but glass white sheets are prone to a large number of scratches during processing, which needs to be processed by grinding In the repair process, the scratches of knot repair account for more than 10%. Contents of the invention [0003] In order to overcome the above-mentioned defects, the purpose of the present invention is to provide a protective paint for glass protection by silk screen printing before material cutting, reduce the scratches of white glass, reduce the labor cost of grinding repair work, reduce the cost of grinding equipment, and reduce the a...
