ADHESIVE TAPE COMPOSITION HAVING EASY REWORKABILITY FOR ELECTRONIC AND ELECTRIC MATERIALS, ADHESIVE TAPE FOR REWORK OF ELECTRONIC AND ELECTRIC MATERIALS, AND REWORK METHOD OF ELECTRONIC AND ELECTRIC MATERIALS

摘要

The present invention relates to an adhesive tape composition having easy reworkability for electronic and electric materials, an adhesive tape for rework of electronic and electric materials, and a rework method of electronic and electric materials. According to the present invention, the adhesive tape for electronic and electric materials is manufactured from a composition prepared by adding 1 to 10 parts by weight of an alcohol absorbent solution to 100 parts by weight of a blending solution and blending the same wherein the blending solution is prepared by blending 20 to 30 wt% of a styrene-butadiene-styrene (SBS) block copolymer, 15 to 25 wt% of an aromatic modified terpene resin, 10 to 15 wt% of a hydrocarbon resin, 3 to 5 wt% of a hydrocarbon polymer, 0.1 to 1 wt% of an antioxidant, and the remainder of a solvent. According to another embodiment of the present invention, the adhesive tape having easy reworkability is comprised of three layers (11, 12, 13) in which a cushion layer (11) is formed in the center of the adhesive tape, a module layer (12) is formed on one side of the adhesive tape, and a battery layer (13) is formed on the other side of the adhesive tape wherein a silicone PET liner (20) is attached to the module layer (12) and the battery layer (13) respectively. The cushion layer (11) is formed of a composition prepared by adding 1 to 10 parts by weight of a micro-ball solution obtained by blending 10 to 30 parts by weight of micro-balls, i.e., expandable capsules with 90 to 70 parts by weight of a solvent to 100 parts by weight of a solution and blending the same wherein the solution is prepared by blending 20 to 30 wt% of the SBS block copolymer, 15 to 25 wt% of the aromatic modified terpene resin, 10 to 15 wt% of the hydrocarbon resin, 3 to 5 wt% of the hydrocarbon polymer, 0.1 to 1 wt% of the antioxidant, and the remainder of the solvent.;COPYRIGHT KIPO 2018
