Abstract

The invention discloses environment-friendly antibacterial sponge and a preparation method thereof. By adopting a nano Ag-Zn / chitosan antibacterial agent, the defects of easy ageing and color change as a result of active chemical properties of the singly used nano silver antibacterial agent are overcome. By adding a nano silver-zinc compound antibacterial agent into sponge, the sponge is better insterilizing effect and higher in stability. The used components are green and environment-friendly degradable material, a prepared product is also more green and environment-friendly, has good biocompatibility and is harmless to human body in preparation and application processes.

Description

technical field [0001] The invention belongs to the field of sponge products, and in particular relates to an environment-friendly antibacterial sponge and a preparation method thereof. Background technique [0002] Sponge is a very common porous material with good water absorption, some of which have good elasticity, deformation recovery and other properties, and can be used to clean items or to produce some comfortable and soft seat cushions. [0003] As a daily necessities, artificial sponge has existed for decades. The sponge products sold in the market are mainly made of polyurethane and polystyrene. Not only the production process will pollute the environment, but also the discarded sponge is difficult to degrade. The raw material of artificial sponge mainly comes from petroleum. With the continuous reduction of petroleum resources, the source of raw material will also be a serious problem. After entering the 21st century, people have a better understanding of enviro...
