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....

Abstract

High-temperature type peelable glue for processing machining protection, and a preparation method thereof relate to peelable glue. The invention provides high-temperature-resistant type peelable glue mainly applied for machining protection of glass of a cover plate of a touch screen and for processing machining protection in an OGS (One-Glass Solution) technology, and a preparation method of the peelable glue. The high-temperature-resistant type peelable glue for processing machining protection comprises the following raw materials: rubber, a crosslinking accelerant, EVA resin, n-butyl stearate, liquid oil, esters, calcium carbonate, silica, dye, a defoaming agent and a leveling agent. The preparation method of the high-temperature-resistant type peelable glue for processing machining protection comprises the following steps of: 1) evenly dispersing the rubber, liquid oil, ester, EVA resin and n-butyl stearate; 2) then adding the dye and filler, and evenly stirring; 3) grinding the materials obtained from the step 2); and 4) adding the crosslinking accelerant into the materials ground in the step 3); and 5) filtering to obtain the high-temperature-resistant type peelable glue for processing machining protection.

Description

technical field [0001] The invention relates to a peelable glue, in particular to a high-temperature-resistant peelable glue mainly used in the processing protection of the cover glass of a touch screen and the processing protection of each process in the OGS process and a preparation method thereof. Background technique [0002] As a high-strength, scratch-resistant glass, touch screen cover glass is widely used in high-end smartphones, tablet computers, flat-panel TVs, and industrial and commercial touch screens. (1) In the field of touch screen cover glass or ITO glass processing, the glass surface will be scratched during the process of opening, edging, and polishing. In order to improve the yield, some companies use protective glue to prevent scratches. hurt. (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; esp...
