Touch screen protective ink

Abstract

The invention discloses a touch screen protective ink, which is prepared by mixing the following raw materials in portion: 100 to 250 portions of chlorethylene-vinyl acetate copolymer fluororesin, 100 to 300 portions of polyvinyl chloride A, 150 to 300 portions of polyvinyl chloride B, 1 to 3 portions of C23H16n8Cu, 20 to 60 portions of non-migrating macromolecular polyester plasticizer, 120 to 300 portions of diisononyl trimellitate, 20 to 70 portions of butyl benzyl phthalate, and 30 to 80 portions of dioctyl phthalate. The touch screen protective ink is used for protecting the surfaces of an ITO film and ITO glass in a raw material for preparing a touch screen. The touch screen protective ink plays a role in protection after heat curing or ultraviolet irradiation after printing and can be completely peeled off after use; and the touch screen protective ink has no residual adhesive bright edges, good toughness, no color change, easy peeling off, no holes, no residues and the like when peeled off after use. The touch screen protective ink can be applied to all ITO films and ITO glass on markets.

Description

technical field [0001] The invention relates to ink, in particular to a touch screen protective ink. Background technique [0002] In the prior art, the surface of the ITO film and the ITO glass in the touch screen production raw materials should be protected by heating and curing after printing with ink; when the existing ink is peeled off, there are the following disadvantages: there is residual glue and bright edges, and the toughness is not good.
