Description
Technical field
The present invention relates to protect glue technical field, be specifically related to a kind of touch-screen protection glue and preparation method thereof.
Background technology
Along with developing rapidly of information technology and plane Display Technique, the application of touch-screen is more and more general. The large information query system to public place, little of PC, panel computer, mobile phone, touch-screen and our life are closely bound up. In the production process of touch-screen, need to can protect glue to carry out temporary protection repeatedly to touch-screen glass by using. Protection glue is mainly used on the ITO plated film of transparent conducting glass in touch-screen, film, plays insulation, moistureproof and protect. When use by serigraphy on PET, ITO film and ito glass, baking is played the effect that prevents that material from being polluted or scratching in subsequent production process after film forming, before the upper and lower circuit of touch-screen is bonding, available simple and easy method is peeled off.
The Chinese invention patent application that is 201310003438.0 as application number discloses the touch-screen temporary protection peelable blue glue of heat cure non-solvent and preparation method, peelable blue glue consists of: 50 ~ 70 parts of modified acrylic ester resins, 20 ~ 30 parts of acrylate monomers, light curing agent 1.0-5.0 part, thixotropic agent 0.1-1.0 part, auxiliary agent 0.1-5.0 part, pigment 0.1-1.0 part; Described preparation method is: accurately take various raw materials by formula rate, first modified acrylic ester resin, acrylate monomer, light curing agent, auxiliary agent, pigment are added in reactor and stirred successively, after stirring, add thixotropic agent, discharging after being uniformly dispersed. But above-mentioned protection glue acid-proof alkaline is poor, pliability is poor, be difficult for peeling off, easily residual.

Micron tetrafluoroethene powder and nanometer tetrafluoroethene powder constituent that described tetrafluoroethene powder is 2:15-1:15 by mass ratio, the particle diameter of described micron tetrafluoroethene powder is 30-40 μ m, the particle diameter of described nanometer tetrafluoroethene powder is 100-200nm.
Described organic pigment is barba hispanica, ultramarine blue, cobalt blue or phthalocyanine blue, and the particle diameter of described organic pigment is controlled between 10-200 micron.
Described organobentonite and talcous particle diameter are controlled between 10-200 micron.
A preparation method for protection glue for touch-screen, obtains a kind of touch-screen protection glue by the organic fluorinated silicone modified acrylic resin of formula ratio, phenolic aldehyde epoxy acrylic resin, chlorinated polypropylene, vinylacetate, 1-hydroxy-cyclohexyl phenyl ketone, dimethicone, organobentonite, polytetrafluoroethylene (PTFE), talcum powder, organic pigment after mixing.
" the synthetic and performance study of organic fluorinated silicone modified acrylic resin " that the preparation method of organic fluorinated silicone modified acrylic resin can deliver referring to author " Shi meter Chao " in the master thesis of Shandong University. Organic fluorinated silicone modified acrylic resin heat resistance, acidproof, good salt tolerance.
Chlorinated polypropylene of the present invention can anti-acid with strong oxidizing property.
Polytetrafluoroethylene (PTFE) nature is stable, is insoluble in water, acid, alkali or organic solvent, is good acidproof raw material. Micron tetrafluoroethene powder and nanometer tetrafluoroethene powder in this particle diameter and ratio range can coordinate better, both little quality and the high surface energy of nanometer tetrafluoroethene powder can have been utilized, make nanometer tetrafluoroethene powder be attached to a micron tetrafluoroethene powder surface, form core the composite construction of shell, make again in follow-up mixed process, nanometer tetrafluoroethene powder is attached to micron surface of tetrafluoroethene powder along with micron tetrafluoroethene powder moves together, has effectively avoided the agglomeration of nanometer tetrafluoroethene powder; In addition because nanometer tetrafluoroethene powder has high surface energy, the combination of the macromolecular chain in it and above-mentioned several resin is tightr, therefore micron tetrafluoroethene powder can be by being attached to the combination of the macromolecular chain in its surperficial nanometer tetrafluoroethene powder and above-mentioned several resin, be not attached to the nanometer tetrafluoroethene powder of micron tetrafluoroethene powder surface by the various gaps that are filled in above-mentioned resin, final all micron tetrafluoroethene powder and nanometer tetrafluoroethene powder all obtain dispersed, have improved acid resistance of the present invention.
The polytetrafluoroethylene (PTFE) that the present invention adds coordinates with above four kinds of resins, greatly strengthen acid-proof alkaline of the present invention, the talcum powder adding can improve plasticity and the pliability of thermoplasticity film-forming resin on the one hand, can be used as on the other hand the dispersant of polytetrafluoroethylene (PTFE), be convenient to polytetrafluoroethylene (PTFE) and evenly spread in resin matrix.
The present invention has added appropriate dimethicone, is not affecting under the prerequisite of other performances, and the present invention is more easily peeled off. In addition, the existence of dimethicone is also more conducive to the dispersion of polytetrafluoroethylene (PTFE). Dimethicone of the present invention has lacked, and does not have corresponding effect, many, and dimethicone can move and ooze out, and affects performance of the present invention.
Organobentonite of the present invention is through disperseing, and meeting and the abundant combination of resin, as same rigid link chain, have humidification for acid-proof alkaline of the present invention. But bentonite content can not be too high, can make paint-based than increasing, resistance to acids and bases reduces. Therefore, be advisable with the content of the scope of the invention.
The control of organobentonite of the present invention and talcum powder particle diameter, be all little quality in order to coordinate above-mentioned nanometer tetrafluoroethene powder, high surface energy and form core the composite construction of shell, this is that material obtains homodisperse key factor.
Compared with prior art, beneficial effect is in the present invention:
The present invention adopts the raw materials such as organic fluorinated silicone modified acrylic resin, phenolic aldehyde epoxy acrylic resin, chlorinated polypropylene, vinylacetate, polytetrafluoroethylene (PTFE), organobentonite, talcum powder to cooperatively interact; learn from other's strong points to offset one's weaknesses; the protection glue good film-forming property making; after heat cure film forming, there is good toughness, flexibility and acid-proof alkaline; do not pollute electronic component or circuit board surface, continuous glue; and after in touch-screen manufacturing process, conducting film protection technique completes; easily peel off, do not have and remain in material surface or contaminated materials.
