Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is made further
Ground describes in detail.
The embodiment of the present invention eliminates the insulating black ink of ITO line shadow, includes following composition by weight percentage: modified epoxy
Resin gloss oil 70～80%, insulation carbon black 15～18%, powder body 5%, dispersant 2～3%, levelling agent 1～2%, defoamer 1～
2%；Described modified epoxy gloss oil admittedly containing 65%, solvent DBE15%, solvent isophorone 20%.
The present embodiment additionally provides the manufacture method of a kind of insulating black ink eliminating ITO line shadow, comprises the steps:
Prepare gloss oil: first pour in Scattered Kettle by solvent DBE15 part isophorone 20 parts, stirring at low speed, in whipping process, weigh
Go out 65 parts of modified epoxy solids, slowly pour in Scattered Kettle, improve rotating speed and rise to 1200 turns, continue 6 hours～8 hours admittedly
Body is completely dissolved complete prepared A gloss oil；
Preparation mixing slurry: weigh 70 parts of A gloss oil in reactor, low speed 200 turns stirring, stir while at the uniform velocity add insulate carbon black 15%～
18%, powder body 5%, dispersant 2%～3%, levelling agent 1%～2%, defoamer 1%～2%, stirring obtain for 20～30 minutes
To mixed slurry B；
Preparing finished product: mixed slurry B carries out after stirring sand milling, sand milling temperature controls at 40 DEG C-65 DEG C, and 3 fineness of sand milling control
3 μm～5 μm obtain finished product C.
Modified epoxy (or modified polyester resin) used meets the requirement of blanking ITO technique.Binder is this blanking
The main film forming substance of ink, has the ability being attached on ITO and strengthening glass, is provided simultaneously with high-insulativity (pressurization 5000V
Voltage measurement resistance wants >=4G Europe).Selected modified epoxy possesses light folding rate after reacting with firming agent will be with ito film layer
Refractive index synchronize.Different anaclasis can not be produced and cause different aberration.And the carbon black of specific colourity can be allowed in binder
Middle good dispersion, mobility are little, can give ink film related physical and chemical.When silk screen printing figure, make specific black
Degree carbon black forms the print material of certain viscosity, to complete the figure transfer of mode of printing.Printing solidification after, make specific blackness carbon black and
Stable bond is formed so that it is the ring meeting touch screen industry surveys requirement and printing precision between filler particles and the base material of specific refraction
Requirement.
The carbon black of the specific blackness used by 3.2 and the filler of specific refractive index can be given mileage and reach handset touch panel
Industry standard.This formula it is crucial that this carbon black selected colourity film forming after cover the strengthening glass of hollow out in ITO and ITO gap
After glass, making human eye observe, can not discover obvious aberration, principle is, specific blackness on the ito layer with in gap: as figure
Shown in 1；
In terms of Visual Observations Observations region from Fig. 1, observation indoor, outdoor, due to specific blackness and the use of the filler of specific refractive index, as
Shown in Fig. 2；
When in the case of specific blackness, as shown in Figure 3；
Understanding from the graph, when angle of incidence is identical, and refraction angle is identical, simultaneously in the case of specific blackness, we just do not see I by Visual Observations Observations
The level difference of TO layer and non-ITO layer, thus the effect of the shadow that reaches to disappear.In the case of specific blackness, ITO layer (reflects blue light)
Non-ITO layer (reflects white light), and two kinds of reflection light (utilize the absorption to light of the specific black powder) and allow reflection light in the case of specific blackness
Wave band reaches unanimity.Thus during eye-observation, reflection photochromism is also consistent.
Dispersant helps the uniform filling of the carbon black specific refractive index of specific blackness, is stable in the presence of in binder.Levelling agent,
Defoamer makes to reach smooth, planarization effects without steam bubble, levelling during ink film forming.
Above disclosed it is only one preferred embodiment of the present invention, certainly can not limit the right of the present invention with this
Scope, the equivalent variations therefore made according to the claims in the present invention, still belong to the scope that the present invention is contained.
