Use of high-performance ultra-thin double-sided adhesive tape in wireless charging

A high-performance ultra-thin double-sided adhesive tape, which is prepared by the following steps:

• A1. preparation of high-performance adhesive coating:
• weighing 100-140 parts of high-performance acrylic pressure sensitive adhesive, 15-20 parts of curing agent, and 130-160 parts of ethyl acetate, stirring and mixing them evenly, and setting it aside;
• A2. cleaning a polyester film material, removing oil and impurities on a surface, and setting it aside;
• A3. fully filtering the adhesive coating prepared in step A1 with a 600 mesh filter cloth, and sealing for use after the filtration;
• A4. transferring the adhesive coating prepared by A3 to coat one side of the polyester film material prepared by A2 by using micro-gravure coating;
• A5. drying, and storing a semi-finished polyester film double-sided adhesive tape into a roll;
• A6. transferring the adhesive coating prepared by A3 to coat the other side of a substrate of the semi-finished polyester film double-sided adhesive tape prepared by A4 by using the micro-gravure coating;
• A7. drying, and storing the prepared high-performance ultra-thin double-sided adhesive tape into a roll.
