AI Technical Summary
Technical Problem
Existing escalator handrails, used by an unspecified number of people, are difficult to apply antibacterial films due to their endless track design, and past sterilization units face management and maintenance challenges.
Method used
An antibacterial handrail is manufactured by integrating an antibacterial agent into the synthetic resin, using a canvas woven with conductive yarns and a metal cable, and extruded with TPU resin to form a durable, antibacterial handrail that suppresses static electricity.
Benefits of technology
The antibacterial handrail effectively prevents bacterial growth and reduces safety risks from static electricity, ensuring durability and ease of maintenance.

Abstract
The present invention relates to an antibacterial handrail and a manufacturing method therefor, the method comprising: a canvas preparation step of preparing a canvas to be disposed on the bottom surface of the handrail; a metal cable preparation step of preparing a metal cable embedded long in the longitudinal direction of the handrail to reinforce durability of the handrail; and an extrusion molding step of integrally molding the canvas prepared through the canvas preparation step and the metal cable prepared through the metal cable preparation step into a body, with a synthetic resin being continuously extruded, wherein the synthetic resin in the extrusion molding step is obtained by mixing 4 - 7 parts by weight of an antibacterial agent, 0.5 - 1 parts by weight of a dispersant, 0.3 - 0.6 parts by weight of an antioxidant, 0.2 - 0.5 parts by weight of a coupling agent, and 0.5 - 1 parts by weight of an anti-hydrolysis additive with respect to 100 parts by weight of a thermoplastic polyurethane (TPU) resin.
