Abstract

The invention discloses an antimicrobial HIPS (high impact polystyrene) plastic and a preparation method thereof. The antimicrobial HIPS plastic comprises the following components in parts by weight: 100 parts of HIPS, 0.3-0.5 part of antimicrobial agent and 0.2-0.4 part of dispersant. The antimicrobial agent is one or mixture of nano copper oxide, nano silver oxide, polyhexamethyleneguanidine phosphate and N-(trichloromethylthio)phthalimide. The antimicrobial HIPS plastic disclosed by the invention can be easily processed into various shapes of interior ornaments of automobiles by an injection molding technique. The antimicrobial HIPS plastic disclosed by the invention can still has strong effects of bacterium control and killing and mold resistance after being used for a long time, and is free from the influences of illumination, temperature and other factors.

Description

technical field [0001] The invention relates to an antibacterial plastic and a preparation method thereof, in particular to an antibacterial HIPS 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 directly rela...
