[0063] The present invention also provides a method for preparing an adhesive, wherein the adhesive is the above-mentioned adhesive; the preparation method comprises the following steps:
[0064] S10: Add 0.5-2 parts of surface treatment agent to 3-9 parts of solvent and stir to dissolve in the solvent;
[0065] S20: adding 5 to 30 parts of radio-frequency optimized functional materials into the solution obtained in S10 and stirring;
[0066] S30: continue to add 10-20 parts of oligomers and 50-80 parts of high polymers to the solution obtained in S20 and stir;
[0067] S40: adding 3-10 parts of a crosslinking agent into the solution obtained in S30 and stirring to obtain an adhesive.
[0068] It should be noted that, in the above step S30, it may be: first add the oligomer to the solution obtained in S20 and stir, and then continue to add the high polymer and stir; it may also be: first add the high polymer to S20 to obtain solution and stirred, then continue to add oligome...

[0090] Step 1: apply the above-mentioned adhesive on the peeling surface of the second release film 300, and then put it into an oven with a temperature of 80° C. to bake to form the adhesive layer 200; the preparation method of the adhesive is as follows:
[0091] S10: Add 3 parts of solvent into a polyester bottle, add 0.5 part of surface treatment agent into the solvent and stir to dissolve in the solvent;
[0092] S20: Add 5 parts of radio-frequency optimized functional materials to the solution obtained in S10, and stir with a high-speed stirrer at a stirring speed of 900 r / min for 10 min;
[0093] S30: Add 10 parts by weight of oligomers to the solution obtained in S10, and stir for 10 minutes with a high-speed stirrer at a stirring speed of 900 r / min;
[0094] S40: Add the solution obtained in S30 to 50 parts of high polymer, and stir with a high-speed mixer at a stirring speed of 900r / min for 10min;
[0095] S50: Add 3 parts of cross-linking agent into the solution ob...

[0098] Step 1: apply the above-mentioned adhesive on the peeling surface of the second peeling film 300, and then put it into an oven with a temperature of 100° C. to bake to form the adhesive layer 200; the preparation method of the adhesive is as follows:
[0099] S10: Add 5 parts of solvent into a polyester bottle, add 0.8 part of surface treatment agent into the solvent and stir to dissolve in the solvent;
[0100] S20: Add 10 parts of radio-frequency optimized functional materials to the solution obtained in S10, and stir with a high-speed stirrer at a stirring speed of 1000 r / min for 9 minutes;
[0101] S30: Add 12 parts of oligomers to the solution obtained in S10, and use a high-speed stirrer to stir for 9 minutes at a stirring speed of 1000 r / min;
[0102] S40: Add the solution obtained in S30 to 55 parts of high polymer, and stir with a high-speed mixer at a stirring speed of 1000r / min for 9 minutes;
[0103] S50: Add 5 parts of cross-linking agent to the solution o...
