Abstract

The invention provides a long-acting, anti-bacterial and mould-proof ABS (acrylonitrile butadiene styrene) functional material and a preparation method thereof. The long-acting, anti-bacterial and mould-proof ABS functional material is prepared through mixing and extrusion from components in parts by mass as follows: ABS, an anti-bacterial and mould-proof nano-agent, an antioxidant, a lubricant and white oil. The prepared anti-bacterial and mould-proof ABS functional material has high efficiency, has the anti-bacterial rate larger than 99% and the mould-proof level reaching level 0 and especially is excellent in long-acting performance, and acceleration test simulation proves that the high anti-bacterial rate and mould-proof performance can be kept for 10 years or longer. Further, the material is easy to process and form, environment-friendly and healthy and meets the requirements of regulations such as ROHS, REACH and the like.

Description

Technical field [0001] The invention relates to the field of modified plastics, in particular to a long-lasting antibacterial and mildew-proof ABS functional material and a preparation method thereof. Background technique [0002] With the increase of human activities, environmental pollution has intensified. Among them, various pathogenic bacteria that are strong in survival, easy to mutate and widely exist in nature, seriously threaten human health. Today, when people's requirements for health and environmental protection are increasing, the application of antibacterial plastics in household appliances, household products, food packaging, medical equipment and other fields has attracted more and more attention. [0003] Antibacterial plastic refers to a new type of functional material that inhibits and kills bacteria, molds or viruses attached to the plastic in its own use environment, and keeps itself clean by inhibiting the reproduction of microorganisms. Among them, ABS resin...
