Problems solved by technology

Disposable tableware is convenient and hygienic, and is an indispensable part of our life. However, it is generally made of hard-to-degrade plastic or wood pulp. Tableware made of plastic is not environmentally friendly and has poor antibacterial performance. The cost of finished tableware is high and it is not friendly to the environment
As we all know, silver can be used as an infinite antibacterial agent, but if you directly use silver to make disposable tableware, the cost is very high, which does not meet the market demand

Abstract

The invention discloses degradable environment-friendly antibacterial tableware. The tableware comprises, by weight, 25-40 parts of corn straw fibers, 40-50 parts of starch, 5-10 parts of thermosetting resin, 5-8 parts of oilproof agent, 3-6 parts of waterproof agent and 0.1-0.2 part of nano-silver. According to the tableware, corn straw serves as the main raw material, so that the cost is low, the raw material is wide in source, and the tableware can be completely biodegraded, is environmentally friendly, can be processed into products such as disposable tableware and specific packaging materials, and does not cause white pollution like foaming tableware or plastic tableware. The nano-silver is added in the preparation process to serve as an antibacterial agent of the tableware, has a good antibacterial effect and can effectively prolong the preservation time of food.

Description

technical field [0001] The invention relates to disposable tableware, in particular to a degradable environment-friendly antibacterial tableware and a preparation method thereof.
