Document Type and Number:
WIPO Patent Application WO/2021/147234
Kind Code:
A1
Abstract:
Disclosed are a bactericidal plastic masterbatch, a preparation method therefor and an application thereof. The bactericidal plastic masterbatch is composed of the following components by weight percentage: 95-99% of plastic powder and 1-5% of a bactericidal nanocomposite material; the bactericidal nanocomposite material is composed of fine particles having a particle size of 30 nm-50 nm, and the contents by weight percentage are 20%-80% silver, 10%-50% copper oxide, and 10%-50% zinc oxide. Products prepared by using the plastic masterbatch of the present invention have been tested by an authoritative organization, and the viable bacteria count obtained by letting stand for 24 hours after inoculation was less than 1 cfu/cm2, the number of residual bacteria on a surface was almost 0, and the sterilization rate was close to 100%.
