Abstract

The invention discloses improved antibacterial plastic. The improved antibacterial plastic comprises, by mass, 35-50 parts of a plastic main body, 5-12 parts of a plasticizer, 4-12 parts of a stabilizer and 35-45 parts of an antibacterial agent. The plasticizer is a mixture of dioctyl phthalate and tributyl citrate. The stabilizer is a composite lead salt stabilizer. The antimicrobial agent is a mixture of ammonium dihydrogen phosphate and lithium carbonate. The novel antibacterial plastic has the advantages of use of an inorganic antibacterial agent, high antibacterial activity, antibacterial rate of 80%, and lasting effects.

Description

technical field [0001] The invention belongs to the field of chemical materials, in particular to an improved antibacterial plastic. Background technique [0002] Antibacterial plastic refers to the addition of some specific antibacterial agents to plastics to make plastics inherently antibacterial. It is a new type of material with antibacterial and bactericidal properties, so that the card will be stained on the surface of plastics and their products within a certain period of time. bacteria to kill or inhibit their reproduction. Compared with conventional chemical and physical disinfection methods, the use of antibacterial plastic sterilization has high efficiency and long-term effect, which is economical and convenient. At present, antibacterial plastics are roughly divided into three categories: inorganic antibacterial agents, organic antibacterial agents and natural antibacterial agents, among which inorganic antibacterial agents have the best antibacterial effect.
