▎ 摘　　要

NOVELTY - The long-acting broad-spectrum antibacterial and antiviral composition comprises 1-6 wt.% a nano material, 0.1-1 wt.% an alkylbenzene sulfonate, 1-2 wt.% an antiviral component, 0-2 wt.% a surfactant and balance alkane oil. The nanomaterial comprises graphene or basic zinc carbonate. The surfactant is a cationic surfactant, which is amine salt compounds, quaternary ammonium salt compounds, or heterocyclic compounds. The alkane oil is mineral oil. The antiviral component comprises zinc pyrithione, a tea leaf extract, a phthalo blue derivative, a silver-doped oxide, or chitosan. The tea extract is black tea extract, green tea extract, white tea extract, or black tea extract. USE - Long-acting broad-spectrum antibacterial and antiviral composition for textiles. ADVANTAGE - The softness of the textile is obviously improved through the combined action of the appropriate proportion of the alkylbenzene sulfonate and the surfactant. The tea extract is added into the composition, so that the textile has antibacterial property and certain antiviral ability. The long-acting broad-spectrum antibacterial and antiviral composition can be applied to textiles, and the obtained fabric has high-efficiency antibacterial property, flexibility and wear resistance, and has important significance for improving the life health and the life quality of people. The preparation method is simple and convenient, has strong repeatability and operability, and is favorable for large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a long-acting broad-spectrum antibacterial and antiviral composition.
