Abstract

A technology for manufacturing a writable touch film is disclosed. The UV printing material is obtained by the following steps: step 1, putting the aliphatic polyurethane triacrylate, 1, 6 hexanedioldiacrylate, ethylene glycol diglycidyl ether, castor oil polyglycidyl ether and alkyl modified organosiloxane into a stirring and dispersing machine for mixing to obtain the material 1; 2, adding theweight parts of the hydroxymethyl butyl ester, the organic thermoset polymethylurea resin, 4- Acryloylmorpholine, 2-Hydroxyl-2-Methyl-1-Phenyl-1-Acetone, sulfonyloxy ketone and coloring pigment, further mixing to obtain material 2; Step 3, the material 2 obtained in the step 2 is sent to a bead mill for grinding until the particle size is 300-400nm, and UV printing material is obtained. The invention can write the manufacturing process of the touch film, and the prepared UV printing layer has high printing accuracy, 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...
