Preparation process of nano-silver antibacterial fiber tableware

Abstract

The invention discloses a preparation process of nano-silver antibacterial fiber tableware. The process comprises the following specific steps: I, preparing paper pulp for producing the antibacterial fiber tableware; and II, producing and processing a paper pulp solution prepared in the step I into various antibacterial and environment-friendly tableware products by using paper pulp molding equipment. According to the preparation process, a nano-silver antibacterial agent and conventional paper pulp are extracted in a mixed way through a microwave technology in order that nano-silver antibacterial particles are fully combined into plant fibers. Then, the tableware made of the plant fibers consistently contains nano-silver ions having antibacterial effects, so that the tableware products have anti-bacterial performance; the self-cleaning properties and stain resistance of the tableware products are enhanced; and the antibacterial property and bacteria resistance of the tableware are enhanced. Moreover, the photocatalysis reaction principle of the sterilizing mechanism of the nano-silver antibacterial agent is utilized, so that a very good sterilizing effect can be achieved, and the antibacterial immunity of environment-friendly tableware is enhanced.

Description

technical field [0001] The invention relates to a preparation process of environment-friendly tableware, more specifically a preparation process of nano-silver antibacterial fiber tableware. Background technique [0002] Tableware is a daily necessities that people use a lot, and the hygiene of tableware is also closely related to people's health. At present, tableware needs high-temperature disinfection treatment in daily use (especially public places such as restaurants and hotels), but after disinfection treatment The final tableware will be exposed to various secondary pollution sources during transportation, storage, and use, and secondary pollution is inevitable, so the hygiene of tableware is very worrying, especially the pollution of primary tableware. In particular, how to enhance the antibacterial properties of tableware has become a research direction in the industry. [0003] In recent years, the self-assembly and loading synthesis technology of nanoparticles wi...

[0009] For example, the Chinese patent publication number is CN 1718926A, which discloses a self-sterilizing plant fiber tableware. This patent is also a bactericidal mechanism using nano-silver antibacterial agents. Coagulation destroys the activity of cell synthesis enzymes, and the cells lose their ability to divide and proliferate and die. However, this patent simply mixes the silver-loaded antibacterial agent through a mixer, and then uses it to produce tableware by hot pressing. The process is simple and rough, and the realizability is poor. , the amount of silver-loaded antibacterial agent used is huge, and the nano-silver antibacterial agent cannot be fully mixed with the fiber pulp solution, let alone applied to large-scale processing and production
