Abstract

The invention relates to a degradable material for tableware. The degradable material comprises the following raw materials by weight percentage: 40-50% of polylactic acid, 0.1-1% of dialkyl p-biphenol, 0.1-3% of boron nitride, 0.1-3% of butylhydroxyoxo-stannane, 0.1-3% of calcium stearate and 40-60% of polypropylene. The material has the characteristics of high degradable efficiency, excellent mechanical properties, and low raw material cost.

Description

technical field [0001] The invention belongs to the technical field of material science, and in particular relates to a degradable material for tableware. Background technique [0002] Plastic is a cheap and high-quality material. However, with the widespread use of plastic bags and plastic thin products, it has been found that the intrinsic life of plastic thin products is much longer than its service life. The inherent durability of plastics increases the proportion of urban solid waste, and the discarded plastic thin products (such as plastic bags, plastic packaging, disposable plastic products, mulch, etc.) pollute the environment for a long time, and gradually become White pollution has become one of the major problems plaguing human survival and development in the 21st century. [0003] In order to reduce white pollution and protect the ecological environment, the research, development and use of biodegradable plastics are becoming more and more important and urgent. ...
