Problems solved by technology

[0006] 2) The preparation process of peelable ink is cumbersome and costly
Most of the existing peelable inks in the market are polyurethanes, acrylates and their copolymers. The production process needs to go through reaction processes such as emulsion polymerization, and most of the raw materials used are relatively expensive. Due to the large demand for peelable inks in actual production and the It cannot be recycled and reused, so high cost has become a major factor hindering the popularization of current touch screens

Abstract

The invention relates to a non-solvent type high-temperature resistant strippable protection ink and a preparation method of the ink. The ink comprises the following raw materials by weight parts: 55 to 65 parts of vinyl chloride-acetate copolymer, 35 to 45 parts of plasticizer, 0.2 to 0.5 parts of epoxy resin, 0.5 to 1 part of heat stabilizer, 1 to 2 parts of fumed silica, 0.3 to 0.5 part of toner, 0.6 to 1 part of flatting agent, 0.6 to 1 part of de-foaming agent, and 0.6 to 1 part of surfactant. The ink prepared by the invention uses the non-solvent formula, has no volatile substances in the printing and film-forming processes, and is of non-reaction type; and in addition, the film forming condition is simple and the property of the film is excellent.

Description

Technical field [0001] The invention relates to a non-solvent high temperature resistant peelable protective ink and a preparation method thereof, and belongs to the field of functional polymer materials. Background technique [0002] With the continuous development of touch screen technology, touch screen mobile phones and tablet computers are gradually becoming the mainstream of mass consumption. In the process of producing touch screens, the ITO layer of the touch screen needs to be protected against high temperature and acid and alkali corrosion in a specific process. After this process, the protective film needs to be peeled off to proceed to the next process. Therefore, today with the increasing demand for touch screens, the need for peelable protective films that are easy to print, have good adhesion and are easy to peel off, and have good mechanical properties has become more urgent. [0003] Peelable protective ink is a kind of temporary protective ink. Similar to ...
