Abstract

The invention discloses a nano-antibacterial plastic and a preparation method thereof, and belongs to the technical field of new materials. The technological process for preparing the nano-antibacterial plastic comprises the steps of feeding reaction, salt leaching, activation, ball milling, carrier forming, alkaline leaching, hot pressed sintering, pressurized plasma etching, material mixing and finished product obtaining. According to the nano-antibacterial plastic prepared by the preparation method of the invention, modified magnesium calcium oxide is used as a carrier, modified nano particles are used as antibacterial particles, the surface of the carrier is coated with the modified nano particles through mutual attraction of electric charge force; and when the prepared nano-antibacterial plastic is put into use, the nano-antibacterial particles are uniformly dispersed in the plastic while the antibacterial effect is achieved, so that the wear resistance of the nano-antibacterial plastic is improved; and due to lower surface energy, the nano-antibacterial particles have smaller surface tension, and therefore, a plurality of nano mastoids are formed on the surfaces of the nano-antibacterial plastic, so that the waterproof performance of the nano-antibacterial plastic is realized while the nano antibacterial plastic is antibacterial and wear-resistant.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a nano antibacterial plastic and a preparation method thereof. Background technique [0002] Antibacterial materials refer to functional materials that have antibacterial or killing effects on microorganisms. In nature, many substances have the function of killing microorganisms and keeping microorganisms growing and multiplying, and are used by people, such as some substances and metals and their compounds, Organic compounds and some natural substances with antimicrobial groups. The active ingredients of antibacterial materials are antibacterial agents. According to the chemical composition and source, antibacterial agents can be divided into inorganic antibacterial agents, organic antibacterial agents and natural antibacterial agents. [0003] Antibacterial plastics currently on the market can only achieve antibacterial effects. After a long period of use, the antibacter...
