Abstract

The invention discloses a degradable disposable tableware material.The material is prepared from the following raw materials in parts by weight. 35 to 55 parts of hyperbranched polylactic acid; 5-10 parts of puffed rice flour; 3 to 6 parts of a molecular sieve, 8 to 12 parts of plant fiber powder, 15 to 20 parts of cinnamic acid / linalool oxide / tetrahydrofurfuryl acrylate / polyethylene glycol monoallyl ether copolymer, 0.5 to 1.5 parts of a plasticizer, 0.03 to 0.05 part of non-butyltin esterification catalyst KR-4100A and 0.5 to 1.5 parts of a coupling agent. The invention also discloses a preparation method of the degradable disposable tableware material. The degradable disposable tableware material disclosed by the invention is good in degradability, high in mechanical strength, good in plasticity and heat resistance, and safe and environment-friendly to use.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to a degradable disposable tableware material and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, various disposable daily necessities emerge in an endless stream. As a common disposable daily necessities, disposable fast food tableware is widely used in countries all over the world due to its advantages of hygiene, heat preservation and low price. However, disposable While the widespread use of tableware brings convenience to people's lives, it also causes serious white pollution to the environment. These disposable tableware are difficult to recycle and process, and are not easy to degrade in the natural environment, which poses a serious threat to people's health. [0003] In order to solve the problem that traditional disposable tableware is not easy to degrade, researchers from various countr...
