Embodiment 1

[0032] Each raw material was weighed according to the data corresponding to Example 1 in Table 1. Mix the components uniformly in a high-speed mixer, control the speed at 300-400 rpm, mix for 5-10 minutes, then melt and knead in a twin-screw extruder, extrude and granulate, and control the barrel temperature at 200-220°C, the extruded polypropylene material is cooled in cold water at 10-40°C to form the antibacterial polypropylene plastic.

Abstract

The invention discloses an antibacterial polypropylene plastic and a preparation method of the antibacterial polypropylene plastic. The antibacterial polypropylene plastic comprises the following components by weight: 100 parts of polypropylene, 0.2-0.6 parts of antibacterial agent and 0.1-0.5 parts of dispersant, wherein the antibacterial agent is one or a mixture of nanometer zinc oxide, nanometer silver oxide, polyhexamethyleneguanidine phosphate and N-(trichloromethylthio) phthalimide. The antibacterial polypropylene plastic still has good effects of inhibiting and killing bacteria and preventing mould after being used for a long time, and is not influenced by factors such as illumination and temperature. The antibacterial polypropylene plastic can be easily processed by an injection process into automotive upholsteries in various shapes, such as an inner cover plate for a glove box, a glove box hopper, an auxiliary instrument board body, a storage box gasket and a panel storage box.

Description

technical field [0001] The invention relates to an antibacterial plastic and a preparation method thereof, in particular to an antibacterial polypropylene plastic and a preparation method thereof. Background technique [0002] With the rapid development of industry and the continuous improvement of people's living standards, people pay more and more attention to environmental hygiene and self-health. Microorganisms such as harmful bacteria, fungi and viruses in nature are the main reasons for human beings to suffer from infection and induce diseases. The Black Death that caused the death of one-third of the population in Europe in the middle of the 14th century AD and the influenza that killed more than 20 million people worldwide in the early 20th century; "Mad Cow Disease", "Foot-and-Mouth Disease", "Anthrax" in the United States, and the Severe Acute Respiratory Infection Syndrome SARS that appeared in the spring and summer of 2003, these infectious diseases are all dire...
