Benefits of technology

The technical effect that this new technology can improve upon existing methods for producing high-quality materials or products by improving their quality without adding extra steps like chemicals or energy sources.

Problems solved by technology

This patented technical solution involves adding certain ingredients called “antimicrobial” substance (AMS) that helps prevent bacteria from growing inside household items like clothes. These Ams help keep them clean by killing harmful microbes without causing damage themselves.

Embodiment Construction

[0017] In this embodiment, the attapulgite-silver nanocomposite antibacterial material not only has exchangeable silver ions on the surface of nanorod-shaped attapulgite crystals, but also is loaded with nano-silver particles. Attapulgite clay with attapulgite crystal content greater than 50% and carbonate content less than 10% is selected, and the weight ratio of attapulgite clay to silver is 1000:1-100:5.

[0018] In the present embodiment, the preparation method of attapulgite-silver nanocomposite antibacterial material is:

[0019] 1. The attapulgite clay layer is mined in layers, and high-quality ore types are selected. Specifically, attapulgite clay with attapulgite content greater than 50% and carbonate content less than 10% can be selected.

[0020] 2. Grind the attapulgite clay to 100-320 mesh, make it into 1-40% water suspension, ideally about 10%, adjust the pH value to 10-12, and age for 24 hours, then stir for 0.1- 4 hours to fully disperse the attapulgite fiber ...

Abstract

Attapulgite-silver nano composite antiseptic material and its preparation method is provided, which characterized in that exchangeable silver ion and nano silver particle exist on the surface of nano bar-shaped attapulgite.It is prepared that attapulgite clay act with silver reagent under the presence of surfactant and organic reductant. Silver particle with grain size being several nanometer has large activity, can continuously slowly release antiseptic silver ion. Nano silver particle bind fast with attapulgite,so attapulgite-silver nano composite antiseptic material has good antiseptic property,can be widely used in chemical fiber, plastics etc.
