Abstract

The invention discloses an acrylonitrile-butadiene-styrene material with an excellent antibacterial performance and a preparation method thereof. The steps include: subjecting nanometer TiO2 particles to a doping process so as to obtain doped nanometer TiO2 particles, obtaining modified nanometer TiO2 particles through a coupling modified process, further performing a melt extrusion of the modified nanometer TiO2 particles and the acrylonitrile-butadiene-styrene to prepare the ABS material with the excellent antibacterial performance, wherein the ABS material with an excellent antibacterial performance consists of the following raw materials of, by weight, 93-97% of the ABS, 1-5% of the modified nanometer TiO2 particles, 0.2-1% of dispersing agents, 0.1-1% of antioxygens and 0-3% of other additives. The acrylonitrile-butadiene-styrene material with the excellent antibacterial performance and the preparation method thereof attach a certain antibacterial performance to the ABS material on the basis of guaranteeing the original performances of the ABC material, and have a good application prospect.

Description
