Abstract

The invention relates to a controllable light-biodegradation nanometer antibiotic plastic and its preparation. The invention comprises waste and old vinyon, modified nanometer TiO2, modified amidon, calcium carbonate and photosensitizer. The invention reduces pollution of waste and old vinyon, avoids resource extravagant and can produce new plastic products with antibiosis and degradability.

Description

Technical field [0001] The present invention relates to a controllable light-biodegradable nano-antibacterial plastic and its preparation method, especially the use of waste plastics to organically combine the production of controllable light-biodegradation and nano-antibacterial. Biodegradable nano antibacterial plastic and its preparation method. Background technique [0002] The use of waste plastics to produce controllable light-biodegradable nano-antibacterial plastics refers to the combination of polyethylene masterbatches, antibacterial masterbatches, biodegradable masterbatches and photodegradable masterbatches made of waste plastics. The produced plastic products have dual degradability and antibacterial properties. At present, there is no similar product in China. At present, the antibacterial agent widely used in antibacterial materials is silver-based antibacterial agent. Although its bactericidal performance is high, it is easy to change color when it is expos...
