Long-acting, anti-bacterial and mould-proof ABS (acrylonitrile butadiene styrene) functional material and preparation method thereof

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.
