2. The high gloss adhesive tape according to claim 1, wherein the lubricant is at least one of white oil, silicone oil, fatty acid amide, paraffin wax, polyethylene wax and ethylene bis-stearamide.
3. The high gloss adhesive tape according to claim 1, wherein said polyfunctional comonomer is at least one of 1,2, 4-trimellitic anhydride, trimethylolpropane, glycerol, pentaerythritol, pyromellitic dianhydride and 3,3 ', 4' -biphenyl tetracarboxylic dianhydride.
4. The high gloss adhesive tape according to claim 1, wherein the inorganic nanomaterial is fumed silica.
5. The high gloss adhesive tape according to claim 1, wherein said plasticizer is at least one of polyethylene glycol, glycerin, tributyl citrate, acetyl tributyl citrate and acetyl trioctyl citrate.
6. The high gloss adhesive tape according to claim 1, wherein said solvent is at least one of propylene glycol methyl ether, dipropylene glycol methyl ether and isopropyl alcohol.
7. The high gloss adhesive tape according to claim 1, wherein the base film layer has a thickness of from 70 to 80 μm.
8. The high gloss adhesive tape according to claim 1, wherein the adhesive layer has a coating thickness of 70 to 90 μm.
9. The preparation method of the high-glossiness adhesive tape is characterized by comprising the following steps of:
step 1: weighing unsaturated polyester resin and lubricant, heating and mixing to obtain a material A, wherein the heating and mixing temperature is 185-200 ℃, and the heating and mixing time is 0.8-2.5h;
step 2: weighing polyfunctional comonomer, inorganic nano material, plasticizer and solvent, vibrating for 10-12min, heating to 70-80 ℃, adding diaminodiphenyl ether, vibrating for 4-6min, heating to 90-100 ℃, reacting at constant temperature for 0.5-1.0h, and distilling to obtain material B; adding the material B into the material A in 3-5 batches, heating to 200-250 ℃, reacting for 2-3h, and preparing a film to obtain a base film layer;
step 3: and (3) coating sizing materials of the adhesive layer on the base film layer obtained in the step (2), irradiating with ultraviolet, and compositing with the release layer to obtain the adhesive tape with high glossiness.
