Abstract

The invention discloses degradable tableware and a preparation method thereof. The degradable tableware is prepared by the following raw materials in parts by weight: 200-300 parts of plant fiber slurry, 20-30 parts of edible gum, 30-50 parts of polylactic acid, 20-25 parts of filler, 20-30 parts of stearic acid, and 3-8 parts of acrylic ester. The prepared degradable tableware is capable of usingthe plant fiber slurry as a main material, using the easily degraded polylactic acid, the stearic acid and the acrylic ester as auxiliary materials, easily degraded integrally, and can be used as anorganic fertilizer after degraded. The prepared degradable tableware is good in water resistance and oil resistance, and capable of meeting requirements of disposable tableware. The prepared tablewareis superior to plastic tableware in compressive strength, and has extensive market prospect.

Description

technical field [0001] The invention belongs to the technical field of preparation of environment-friendly tableware, and in particular relates to a degradable tableware and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the rapid development of the tourism industry, people consume more and more fast food. The rapid development of the fast food industry has led to a rapid increase in the demand for disposable fast food tableware, which has led to an explosion of foamed plastic tableware for more than ten years. Disposable tableware is developing rapidly, and the use of disposable fast food boxes is becoming more and more extensive, resulting in "white pollution" becoming more and more serious. In my country, landfill and incineration are generally used to deal with white pollution, but the fluorine and chlorine contained in foamed plastic tableware Substances such as carbides and carbides will produce substances that d...
