Abstract

The invention discloses a manufacturing process of a writable touch film, and its UV printing material is obtained through the following steps: step 1, the aliphatic polyurethane triacrylate, 1,6 hexanediol diacrylate, Ethylene glycol diglycidyl ether, castor oil polyglycidyl ether and alkyl modified organosiloxane are mixed in a stirring disperser to obtain material 1; step 2, adding the weight part of Butyloxycresyl, organic thermosetting polymethylurea resin, 4‑acryloylmorpholine, 2‑hydroxy‑2‑methyl‑1‑phenyl‑1‑acetone, sulfonyloxyketone and coloring pigment, continue to mix, Obtain material 2; step 3, send the material 2 obtained in step 2 to a bead mill and grind to a particle size of 300-400nm to obtain a UV printing material. According to the manufacturing process of the writable touch film of the present invention, the prepared UV printing layer has high printing precision, high curing hardness and scratch resistance.

Description

technical field [0001] The invention relates to a touch film, in particular to a manufacturing process of a writable touch film. Background technique [0002] UV light curing technology has the advantages of fast curing speed, high production efficiency, good mechanical and physical properties, less pollution, energy saving, etc., and is known as a green technology. With the increasing emphasis on environmental protection and the development of science and technology, the UV curing market is developing rapidly and is widely used in coatings, adhesives, inks, electronic packaging, glass, dental restoration, photolithographic imaging, and biomedicine. Although UV curing technology has made a lot of progress, there are still some problems in application, such as serious oxygen inhibition phenomenon in the existing UV curing system, low curing hardness, high viscosity and poor stability. [0003] Oxygen inhibition refers to the phenomenon that in the free radical photopolymeriz...
