Abstract

The invention discloses an anti-ultraviolet antibacterial plastic, which comprises the following follows by weight: 50-60 parts of PVC resin, 20-40 parts of light calcium carbonate, 5-15 parts of a plasticizer, 5-15 parts of a composite lead salt stabilizer, 5-15 parts of a lubricant, 1-5 parts of a glass based inorganic antibacterial agent, 2-5 parts of an impact resistant modifier ACR, and 2-5 parts of an ultraviolet absorbent. The anti-ultraviolet antibacterial plastic provided by the invention adopts the glass based inorganic antibacterial agent, which can slowly release Ag<+> and generate a good antibacterial effect, and has good bacteriostatic effects on Escherichia coli, Pseudomonas aeruginosa and staphylococcus aureus. The anti-ultraviolet antibacterial plastic provided by the invention has the advantages of excellent and long-lasting anti-ultraviolet effect, cheap components, and easy popularization and application.

Description

technical field [0001] The invention belongs to the field of chemical materials and relates to an anti-ultraviolet antibacterial plastic. Background technique [0002] Antibacterial plastics refer to the addition of one or several specific antibacterial agents to plastics to make plastics inherently antibacterial. Kill or inhibit the reproduction of bacteria on the surface of its products. Compared with conventional chemical and physical disinfection methods, the use of antibacterial plastics for sterilization is efficient, long-lasting, economical and convenient. [0003] At present, the antibacterial agents used in plastics are mainly three series: organic, inorganic and natural. Inorganic antibacterial agents are widely used in antibacterial plastics due to their long antibacterial effect and high temperature resistance, which can adapt to plastic processing. Silver zeolite is currently the most commonly used inorganic antibacterial agent for plastics. Silver zeolite c...
