Peelable mask and preparation method thereof

Abstract

The invention provides a peelable mask and a preparation method thereof. The peelable mask has properties of adhesion, elasticity, peeling strength, high-temperature resistance and the like, the film forming condition is simple, a film has properties of high adhesion, elasticity, peeling strength, high-temperature resistance and the like, quick and integral peeling can be realized, no residue exists after peeling, and the peelable mask is significant in high-temperature resistance, non-sticky, anti-fogging and high in chemical reagent resistance. The peelable mask takes a chlorinated polypropylene-ethylene random copolymer, a vinyl chloride-vinyl acetate-acrylate terpolymer, polystyrene-polyurethane-unsaturated polyester resin as well as organosilicone modified acrylate rubber as main film forming matters and takes epoxy resin, cellulose acetate butyrate and blocked polyurethane as auxiliary film forming matters.

Description

technical field

[0001] The invention relates to a peelable glue and a preparation method thereof, belonging to the field of functional polymer materials. Background technique

[0002] With the continuous development of touch screen technology, touch screen mobile phones and tablet PCs are gradually becoming the mainstream of mass consumption. In the process of producing the touch screen, it is necessary to protect the ITO layer of the touch screen 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, in today's growing demand for touch screens, the need for a peelable protective film that is easy to print, has good adhesion and is easy to peel off, and has good mechanical properties has become more urgent.

[0003] In addition to proper adhesion and peelability to the protective base surface, the peelable adhesive also requires the coating film t...
