This invention is about an adhesive with improved cohesive force and manufacturing method thereof. The invention significantly improves cohesive force of the synthetic rubber (SBR), which is the weak point of the synthetic rubber, by reinforcing clotting force of Rosin using combination of synthetic rubber (SBR) and Rosin. The invention has a combination with mixing ratio of: 46-54 weight part of synthetic rubber (SBR); 18-22 weight part of Rosin; 8-12 weight part of terra alba; 8-12 8-12 wight part of ethyl cellulose, and 8-12 wight part of calcium carbonate. Finally, solvent, two times of the total weight of combination is added. |
