Abstract
Structural members and methods for manufacturing a plastic-based, bulk, antimicrobial structural member of a robot. Such bulk antimicrobial plastic solution can meet the hygienic requirement and the mechanical performance requirement of a structural member of a robot simultaneously. Meanwhile, it may reduce the overall weight of the robot.
Claims23
A structural member of a robot, wherein the structural member is adapted to be exposed to an environment and bear a mechanical load, the structural member comprises:
- a plastic matrix;
- and
- an antimicrobial additive mixed with the plastic matrix comprising:
- a first antimicrobial additive,
- wherein the first antimicrobial additive is a metal ion antimicrobial additive comprising silver ion and copper ion, and wherein the first antimicrobial additive further comprises a first carrier comprising zeolite and glass, for coupling with the metal ion antimicrobial additive, and
- wherein a content of the first antimicrobial additive in the structural member is in a range of 0.5-5 wt %, and
- a second antimicrobial additive,
- wherein the second antimicrobial additive is an inorganic oxide antimicrobial additive and comprises a photo catalyst comprising zinc oxide and titanium dioxide.
A method for manufacturing a structural member of a robot, comprising:
- preparing a plastic matrix;
- and
- mixing an antimicrobial additive with the plastic matrix to form, by injection molding, machining, or 3D printing, the structural member that is adapted to expose to an environment and bear a mechanical load;
- wherein the antimicrobial additive comprises a first antimicrobial additive, a second antimicrobial additive, and a first carrier,
- wherein the first antimicrobial additive is a first metal ion antimicrobial additive and comprises a metal ion comprising silver ion and copper ion,
- wherein a content of the first antimicrobial additive in the structural member is in a range of 0.5-5 wt %, and
- wherein the first carrier comprises zeolite and glass, for coupling with the metal ion,
- wherein the second antimicrobial additive is an inorganic oxide antimicrobial additive and comprises a photo catalyst comprising zinc oxide and titanium dioxide.
