Abstract

The invention discloses an antibacterial transparent polystyrene material and a preparation method thereof. The material is composed of the following raw materials by weight percent: 96 to 98 percent of polystyrene, 1 to 3 percent of TiO2/ZnO composite antibacterial particles, 0.2 to 1 percent of coupling agent, 0.2 to 1 percent of dispersing agent, and 0.1 to 1 percent of antioxidant. The preparation method of the antibacterial transparent polystyrene material is as follows: premixing the components except polystyrene with a high-speed mixer; placing the mixed materials and the polystyrene into the high-speed mixer for mixing; and finally, melting and extruding the mixed materials through a double-screw extruding machine, and cooling and prilling to obtain the polystyrene material. According to the invention, the polystyrene material has an excellent antibacterial property and a good transparency, and the influence on the original mechanical property of matrix resin is tiny, so that the polystyrene material has a wide application prospect.

Description

Technical field [0001] The invention relates to an antibacterial transparent polystyrene material and a preparation method thereof, and belongs to the field of polymer modification and processing. Background technique [0002] As one of the five general plastics, polystyrene (PS) has the advantages of light weight, low price, good dimensional stability and electrical properties, transparent products, and easy processing and molding. It is widely used in automobiles, household appliances, instrument housings, and children's toys. , Office supplies, sports equipment, packaging and other fields. However, polystyrene products are easily contaminated by microorganisms during processing, production, transportation, storage and use, which will cause certain harm to people's health. With the continuous improvement of people's living standards and health awareness, the antibacterial properties of polystyrene are increasingly required, especially when used as daily necessities and childre...
