Abstract

The invention discloses water removal protective ink and a preparation method thereof. The method comprises introducing a hydrophilia 2-acrylamide-methyl propane sulfonic acid molecular structure, designing and synthesizing epoxy acrylic acid resin containing hydrophilic groups, performing screening and optimizing through auxiliaries of diluents, fillers, antifoaming agents and the like with the epoxy acrylic acid resin serving as the body to obtain water removal protective ink. According to the water removal protective ink, outstanding adhesion force is presented on touch screen panel glass or OGS glass matrixes, hollowing, edge warping and the like during cutting scribbing and CNC engraving processes are prevented, stripping can be performed through common hot water, protection film falls off in sheet during stripping, filtering and separation can be performed easily, no damage is caused to glass, the process automatic degree is high, and the ink is safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a water-dehydrating protective ink and a preparation method thereof. Background technique [0002] Touch screen is a simple way of human-computer interaction, mainly used in mobile communication, automobile central control, industrial control, multimedia teaching and other fields. The touch screen panel glass is relatively thin, has high requirements for surface flatness, and is difficult to form. The manufacturing process is much more complicated than that of ordinary flat glass. It is very easy to scratch the glass substrate to a certain extent during machine or other operations, and the scratch rate is generally above 42%, which increases the manufacturing cost of the enterprise and restricts the production capacity of the enterprise. Therefore, when processing touch screens, it is necessary to paste various protective materials on the surface of the panel glass. There are ma...
