However, natural antibacterial agents are usually extracted from a plant, animal or organism. The antibacterial components are relatively single and have a narrow antibacterial spectrum. Antibacterial ingredients are easy to precipitate during use, and the antibacterial effect cannot last
In addition, the existing antibacterial agents cannot have both antibacterial and anti-aging and health care functions. In order to achieve t

Abstract
The invention provides a natural antibacterial anti-aging polypropylene material. The natural antibacterial anti-aging polypropylene consists of the following raw material by weight percent: 65 to 90 percent of polypropylene, 3 to 11 percent of kernel extract, 6 to 20 percent of nano loess, 0.9 to 2.5 percent of peony seed oil and 0.1 to 1.5 percent of alky propyl hydroxysultaine; the raw materials are reasonably compounded and have synergistic interaction with one another by means of a plurality of processing means, so that the polypropylene material has multiple functions such as natural antibiosis, mould resistance, oxidation resistance, far-infrared healthcare and the like, and when the natural antibacterial anti-aging polypropylene material is used for manufacturing a polypropylene product, not only is the antibacterial spectrum wide, the antibacterial capacity high, and the antibacterial effect lasting, but also the anti-aging capacity and mechanical performance are more excellent, after being exposed in sunlight for a long time, the polypropylene material is not discolored, deformed and fractured and is long in service life. Meanwhile, an effect of self-cleaning and purifying the ambient air and eliminating the peculiar smell can be realized, and the health of human body and environmental friendliness are facilitated. Therefore, the application range of the polypropylene is greatly enlarged, and the social, ecological and economical benefit is vast.
Description
technical field [0001] The invention relates to the technical field of polymer materials, in particular to a natural antibacterial and aging-resistant polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a thermoplastic resin produced by the polymerization of propylene, usually a non-toxic, odorless, tasteless milky white highly crystalline polymer. Because of its rich source of raw materials, light weight, excellent processing performance, good mechanical properties, corrosion resistance, and low price, it is widely used in home appliances, automobiles, construction, office, kitchen utensils, toys, food packaging, and daily necessities. occupy a pivotal position in the However, polypropylene has poor impact strength, large molding shrinkage, and is not resistant to thermal oxygen aging and light aging. Many polypropylene products are easy to age, become brittle or pulverized, or even brittle when used outdoors, which...
