the antimicrobial adhesive film using the dispersion solution in which the copper nanoparticle and copper micro particle are mixed to the specific gravity difference and a method of manufacture thereof

摘要

The present invention uses the difference in specific gravity between the copper particles having antibacterial function and the dispersion solvent so that the copper particles are uniformly and evenly dispersed in the dispersion solvent, so that the copper nanoparticles and the copper microparticles form a coating layer on the base film. It relates to an antibacterial adhesive film using a mixed dispersion solution and a method of manufacturing the same. The manufacturing method of the antibacterial adhesive film is 0.03 to 0.5㎛ copper nanoparticles 80 to 99% by weight and 1 to 30㎛ copper microparticles 1 to 20% by weight of the mixed antibacterial copper particles by a dispersion solvent, the 0.03 to 0.5㎛ Due to the buoyancy according to the difference in specific gravity of 80 to 99% by weight of copper nanoparticles, the 1 to 30 μm copper microparticles having a relatively large particle size of 1 to 20% by weight are induced to be evenly dispersed, and 30 to 70% by weight of the copper particles and the above Maintaining a copper particle colloidal solution in which the nanocopper particles and copper microparticles are evenly dispersed in the dispersion solvent by mixing 30 to 70% by weight of a dispersion solvent; In order to prevent precipitation of the copper particles and to rapidly cure the copper particle colloidal solution, 10 to 70% by weight of a thermosetting binder and 0.5 to 10% by weight of a curing agent are mixed with 20 to 89.5% by weight of the copper particle colloidal solution, or , In order to improve moldability and prevent cracking, mixing 10 to 70% by weight of a urethane acrylate-based oligomer, which is a UV curing binder, to 30 to 90% by weight of the copper particle colloidal solution to prepare a copper particle dispersion coating; Forming a contact-type copper particle dispersion coating layer of 3 to 500 μm on one side of the base film by applying the copper particle dispersion coating to a base film in a comma roll, a slow die, a micro roll, a roll to roll, and a screen method; On the other side of the base film, a pressure-sensitive adhesive containing at least one of acrylic (ACRYL)-based, silicone (SILICONE)-based, EVA-based, and polyurethane-based adhesives is used as comma roll, slow die, micro roll, roll to roll, It includes the step of forming a pressure-sensitive adhesive layer forming adhesiveness to the object by applying in a screen method.
