Abstract

The invention relates to an antibacterial enhanced nylon composite material and a preparation method thereof, and belongs to the technical field of macromolecules. The antibacterial enhanced nylon composite material comprises, in weight percent, 13-20% of TPU (thermoplastic urethanes) powder, 8-13% of rare earth TiO2 nano-fibers, 2.0-3.5% of plasticizers, 0.4-1.1% of antioxidants, 0.5-0.8% of lubricating agents and the balance nylon 6 powder. The antibacterial enhanced nylon composite material has good mechanics performances and mechanical properties and excellent antibacterial performances and can be used for production and manufacturing of gear shifting mechanisms and ceiling handles, and body health of users is protected when a product has good mechanics performances.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and relates to an antibacterial enhanced nylon composite material and a preparation method thereof. Background technique [0002] Nylon (PA) is one of the polymer materials commonly used in the manufacture of mechanical parts. Due to the regular structure and high crystallinity of nylon molecules, compared with other engineering plastics, it has outstanding self-lubricating properties and is an ideal wear-resistant material. It can be used in the manufacture and production of various types of different commodities in various fields. However, compared with metal materials, nylon is difficult to withstand high loads during the friction process, making nylon products prone to damage when the load is high, which seriously reduces the service life. In addition, conventional nylon products do not have antibacterial and antibacterial properties, which also limits the scope and performance of the...
