Problems solved by technology

(2) OGS is one of the future development directions of the touch screen industry. Its process is complex and requires cutting, carving, printing and other processes. The glass is easily scratched and polluted; especially in the process of coating and silver plating, due to the processing temperature High, a high temperature resistant peelable protective adhesive is needed to protect the parts that do not need coating and silver plating paste
[0003] Disadvantages of the peelable glue currently on the market: (1) The peelable glue on the existing market contains volatile solvents, which will affect the performance of the scraper, the working environment, and the length of curing time, the process is complicated, and it will affect the touch screen sensor function block Corrosion on substrate
(3) Poor high temperature resistance, especially in OGS processing. Due to the poor temperature resistance of the peelable glue, the yield rate of related products using the OGS process becomes lower. Many touch screen companies are in urgent need of high temperature resistant peelable glue.

Embodiment 1

[0041] The preparation method of the high-temperature-resistant peelable adhesive used for process protection is as follows:

[0042] Disperse rubber, liquid oil, esters, EVA resin and n-butyl stearate evenly in a high-speed disperser; then add dyes and fillers, stir evenly, and grind 4 times with a three-roller mill; the material after grinding Add a cross-linking accelerator to the mixture, and stir it evenly with a planetary mixer; after filtering, a high-temperature-resistant peelable rubber for process protection is obtained. The composition of each raw material is as follows:

[0043] Silicone rubber: 40;

[0044] Triallyl isocyanurate: 4;

[0045] DCP: 0.6;

[0046] EVA resin: 5;

[0047] n-Butyl stearate: 5;

[0048] Epoxidized soybean oil: 3;

[0049] Aromatic oil: 17;

[0050] Acetyl tributyl citrate: 14;

[0051] Calcium carbonate: 5;

[0052] Silica: 1;

[0053] Phthalocyanine dye: 3;

[0054] Defoamer polyether: 0.1;

[0055] Leveling agent polyacrylic...

Embodiment 2

[0058] EPDM rubber: 20;

[0059] Triallyl cyanurate: 2;

[0060] DCP: 0.4;

[0061] EVA resin: 20;

[0062] n-Butyl stearate: 10;

[0063] Epoxidized soybean oil: 5;

[0064] Rubber softening oil: 17;

[0065] DOTP: 21;

[0066] Calcium carbonate: 5;

[0067] Silica: 2;

[0068] Phthalocyanine dye: 4;

[0069] Defoamer polyether: 0.3;

[0070] Leveling agent polyacrylic acid: 0.5.

[0071] This formula has the characteristics of good film-forming toughness, high temperature resistance, high elongation at break, and good peeling ability. It is suitable for the process that requires very strict residual glue in the processing of touch screens. Clean, no glue residue.

Embodiment 3

[0073] EPDM rubber: 15;

[0074] Triallyl cyanurate: 0.5;

[0075] EVA resin: 15;

[0076] n-Butyl stearate: 15;

[0077] Epoxidized soybean oil: 40;

[0078] Rubber softening oil: 15;

[0079] Calcium carbonate: 10;

[0080] Silica: 0.2;

[0081] Phthalocyanine dye: 0.5;

[0082] Defoamer polyether: 0.2;

[0083] Leveling agent polyacrylic acid: 0.1.

[0084] This formula has the characteristics of good film-forming toughness, high temperature resistance, high elongation at break, and good peeling ability. It is suitable for the process that requires very strict residual glue in the processing of touch screens. Clean, no glue residue.

[0085] When in use, it is printed on PET, ITO film and ITO glass by screen printing, and after the film is baked, the film can effectively isolate the object to achieve anti-dirty, anti-rust, anti-acid and alkali, and prevent the material from being damaged in the subsequent production process. The effect of contamination or scratches....
