▎ 摘  要

NOVELTY - A heat-conducting ultra-thin grid adhesive tape comprises 100-120 pts. wt. acrylic adhesive, 10-30 pts. wt. tackifier, 5-15 pts. wt. functionalauxiliary agents, 1-3 pts. wt. flattening agent, 1 to 3 pts. wt. dispersant, 0.5 to 0.3 pts. wt. cross-linking agent and 200-300 pts. wt. solvent. USE - The heat-conducting ultra-thin grid adhesive tape is used in consumer electronics products such as mobile phone, notebook computer, tablet computer and in bonding parts. ADVANTAGE - The adhesive tape having improved heat-conducting property, enables easy heating of the heat dissipation parts, locally. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of heat-conducting ultrathin mesh adhesive tape which involves: 1) adding acrylic acid adhesive, tackifier and solvent into a container, followed by uniformly stirring, adding a functional auxiliary agent and a dispersing agent, uniformly stirring, adding a leveling agent and a crosslinking agent and uniformly stirring to form a colloid; 2) coating the prepared colloid on a release film (1), drying the colloid to form a surface adhesive layer (5), followed by attaching a base material (4) to the surface adhesive layer; 3) continuously coating the other side of the base material attached with the colloid prepared in step 1, and drying to form adhesive surface on the other side; 4) forming a three-dimensional grid organic silicon layer (2) on the surface of the adhesive tape formed in step 3, using an UV-cured flexographic printing equipment, and then attaching another release film; 5) tearing off the release film attached to the surface adhesive layer formed in the step 4, followed by forming a three-dimensional grid organic silicon layer on the surface adhesive layer (5) using UV-cured flexographic printing equipment, and then attaching the release film again. DESCRIPTION OF DRAWING(S) - The drawing shows structural view of adhesive tape.
