Embodiment 1
[0029] A white ink layer with a thickness of 6-8 μm is printed on the glass substrate of the touch screen. The components of the white ink are epoxy resin, titanium dioxide, solvent, dispersant, defoamer, leveling agent, additive and modified nano zinc oxide, and the additive is 4-aminobenzoic acid, maleic acid, Mixture of p-toluenesulfonic acid and sebacic acid. In the white ink, each component is calculated in parts by weight as:
[0030]
[0031]
[0032] Among them, the solvent is a mixture of ethylene glycol ether acetate and ethyl acetate, wherein the volume ratio of ethylene glycol ether acetate and ethyl acetate is 10:2; the modified nano-zinc oxide is nano-zinc oxide processed by vinyl triethyl Oxysilane modification treatment obtains; Dispersant, defoamer and leveling agent can adopt any one in the prior art all can, the present invention does not make special requirement, in order to improve the contrast of experiment, in the specific embodiment of the presen...
