NOVELTY - Engraved code tracing electric core adhesive tape comprises a base layer and an improved tape body layer, and the corona on the surface of the improved tape body layer is provided with brush code printing markers. The preparation of improved tape body layer includes (i) adding 5-10 pts. wt. polybutylene succinate to 15-20 pts. wt. acetone solvent, adding 1-5 pts. wt. isocyanate curing agent, 2-5 pts. wt. modified chitosan and 3-6 pts. wt. graphene-modified magnesium oxide, reacting at 55-65℃ for 20-30 minutes, where the reaction speed is 450-550 revolutions/minute to obtain tape body material, and (ii) coating tape body material on base layer, where the coating thickness is 0.02-0.03 mm, after coating, drying to obtain improved tape body layer. USE - The engraved code tracing electric core adhesive tape is useful for automobile battery. ADVANTAGE - The engraved code tracing electric core adhesive tape has excellent stability, moisture-proof and thermal-resistant effect to improve storage stability of the brush code printing mark.
