Abstract

The invention discloses a degradable master batch, which consists of the following components: 5%-75% of starch, 5%-50% of carbon dioxide polymer, 5%-30% of polyvinyl alcohol, 1%-10% of compatilizer and 1%-15% of plasticizer (all are based on weight percent). The device disclosed by the invention is nontoxic, harmless, clean and pollution-free, and has the advantages of low cost, simplicity in technique, complete degradation and excellent performance.

Description

technical field [0001] The invention relates to the field of biodegradable polymer materials, in particular to provide a degradable masterbatch. Background technique [0002] Environmentally degradable plastics are a new type of plastic. The development of environmentally degradable plastics abroad began in the 1970s. At that time, photodegradable plastics were mainly developed to solve the environmental pollution caused by plastic waste, especially disposable plastic packaging products. In the 1980s, the development and research turned to biodegradable plastics, and biodegradable plastics produced from renewable resources such as plant starch and cellulose and animal chitin instead of petroleum also appeared. [0003] The development and research of degradable plastics in China is basically in sync with the world. However, the research and development of degradable plastics in China began with agricultural mulch. China is a large agricultural country, and the consumption ...
