Abstract

The invention relates to the technical field of touch screen peelable blue gel, in particular to touch screen heat curing peelable blue gel and a preparing method of the touch screen heat curing peelable blue gel. The touch screen heat curing peelable blue gel is composed of, by weight, 30-40% of vinyl resin, 5-10% of alkyd resin, 30-40% of amino resin, 15-32% of plasticizer, 2-4% of filler and 0.1-3% of organic pigments. The vinyl resin, the alkyd resin and the amino resin are adopted to be cooperated and mutually reinforced, the amino resin is used as the cross-linking agent of the alkyd resin and the vinyl resin, the peelable blue gel is made to be good in film-forming property, a paint film which is of a three-dimensional net structure and has obdurability can be obtained through heating, good gloss and good colour retention are achieved, good toughness and good flexibility are achieved, and good heat resistance, good insulativity and good acid and alkali resistance are achieved. After the conducting film protection process in the touch screen manufacturing process is completed, peeling is easy, and the situation that residues exist on the surface of materials, or the materials are contaminated is avoided.

Description

technical field [0001] The invention relates to the technical field of peelable blue glue for touch screens, in particular to a heat-cured peelable blue glue for touch screens and a preparation method thereof. Background technique [0002] With the rapid development of information technology and flat display technology, the application of touch screens is becoming more and more common. As large as information query systems in public places, as small as personal computers, tablet computers, and mobile phones, touch screens are closely related to our lives. During the production process of the touch screen, the glass of the touch screen needs to be temporarily protected many times by using peelable blue glue. Peelable blue glue is mainly used on the transparent conductive glass in the touch screen and the ITO coating of the film, which plays the role of insulation, moisture resistance and protection. When in use, it is screen printed on PET, ITO film and ITO glass, and afte...
