Abstract
The invention discloses protective glue used in the manufacturing procedure of a nano-silver touch screen. The protective glue comprises the following components in parts by mass: 35-55 parts of an acrylic main copolymer, 0.3-1 part of a photoinitiator, 10-20 parts of terpene resin and 0.2-0.8 part of an antistatic agent, wherein the acrylic main copolymer is ethoxylated trimethylol propane triacrylate or propoxylated trimethylol propane triacrylate; the photoinitiator is a mixture of 1-carboxycyclohexyl benzophenone and ammonium salt and the antistatic agent is quaternary ammonium salt. By the protective glue, the problems that precipitates are generated after existing products are baked and the peeling force between the ITO film and a protective film and the warping degree of the protective film do not meet the standards are solved.
Description
Technical field
The invention belongs to touch-screen field, relate to nanometer silver touch screen processing procedure protecting glue, particularly silver slurry silk-screen and yellow technique protecting glue.
Background technology
In nanometer silver touch screen processing procedure, need to utilize screen printing technique and yellow technique to make ITO circuit on ITO FILM surface.For avoiding the ITO FILM back side to sustain damage, FILM back side laminating protective layer of being everlasting; Fig. 1 is ITO FILM and protective membrane composite structure schematic diagram, and the upper surface of ITO FILM1 is manufactured with ITO circuit, and the back side is fitted with protective membrane 2, is the coating performance of both enhancings, usually bonds protective layer 2 and ITO FILM1 by assembly glue 3.
But the problem that after current domestic analogous products ubiquity precipitate and baking, peeling force, angularity are not up to standard, is therefore necessary to develop a kind of Novel nanometer silver touch screen processing procedure protecting glue.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of nanometer silver touch screen processing procedure protecting glue.
For achieving the above object, the invention provides following technical scheme:
Nanometer silver touch screen processing procedure protecting glue, comprises following component by mass:
Vinylformic acid owner polymers: 35-55 part;
Light trigger: 0.3-1 part;
The rare resinoid of terpene: 10-20 part;
Static inhibitor: 0.2-0.8 part.
As preferably of the present invention, described vinylformic acid owner polymers is ethoxylation tricarboxylic propane tri, propoxylation tricarboxylic propane tri or both mixtures.
Preferred as another kind of the present invention, described light trigger is the mixture of 1-carboxycyclohexyl benzophenone and ammonium salt.
As present invention further optimization, described static inhibitor is quaternary ammonium salt.
Beneficial effect of the present invention is: adopt the ITO FILM of protecting glue of the present invention and protective membrane composite structure to starch after silk-screen and after yellow art breading, peeling force becomes 8 ~ 14g/25mm from 5 ~ 10g/25mm through silver, the angularity <8mm of protective membrane (detects protective membrane used and is of a size of 340mm*340mm, base material MD direction percent thermal shrinkage 0.3 ~ 0.5%, TD direction 0.1 ~ 0.2%), ring is surveyed and is separated out without oligopolymer (Oligomer) and cull; Solve the problem that currently available products precipitate, the rear peeling force of baking and angularity are not up to standard.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the invention provides following accompanying drawing and being described:
Fig. 1 is ITO FILM and protective membrane composite structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
Embodiment 1:
The present embodiment is used for nanometer silver touch screen processing procedure protecting glue, comprises following component by mass:

Described light trigger is the mixture of 1-carboxycyclohexyl benzophenone and ammonium salt.
Described static inhibitor is quaternary ammonium salt.
Embodiment 3:
The present embodiment is used for nanometer silver touch screen processing procedure protecting glue, comprises following component by mass:
Vinylformic acid owner polymers: 55 parts;
Light trigger: 0.3 part;
The rare resinoid of terpene: 20 parts;
Static inhibitor: 0.2 part.
Wherein: described vinylformic acid owner polymers is propoxylation tricarboxylic propane tri.
Described light trigger is the mixture of 1-carboxycyclohexyl benzophenone and ammonium salt.
Described static inhibitor is quaternary ammonium salt.
Performance Detection:
First the protecting glue of embodiment 1 is utilized pending ITO FILM and protective membrane to be bonded together; then screen printing technique is utilized to print nano wire at the upper surface of ITO FILM; then ITO FILM is placed in 180 DEG C of environmental drying 30min; and then utilize yellow technique to etch ITO FILM surface, develop, finally ITO FILM is placed in 150 DEG C of environment and is incubated 1 hour.
After testing; after above-mentioned steps process; the peeling force of ITO FILM and protective membrane becomes 8 ~ 14g/25mm from 5 ~ 10g/25mm before; the angularity <8mm (protective membrane is of a size of 340mm*340mm) of protective membrane; separate out without Oligomer and cull after baking; the peeling force comprehensively overcoming existing assembly glue ITO FILM and protective membrane after above-mentioned steps is not up to standard; protective membrane angularity is excessive; there are oligopolymer and cull to separate out, affect the problem of complete processing and product quality.
What finally illustrate is, above preferred embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from claims of the present invention limited range.
