Problems solved by technology

[0005] The current problems of degradable plastics are mainly that they are expensive and difficult to popularize and utilize. Starch-filled plastics cannot be degraded. , Accurate degradation controllability, rapid degradability after use, complete degradability and recycling technology of leftover materials need to be further improved and perfected
Environmentally degradable polymers have not yet had a unified definition in the world and have completely established a unified test evaluation method, identif

Abstract

The invention discloses PBS-based degradable plastic, which is characterized by including the following components, by weight, 50-80 parts of a master batch, 40-80 parts of modified starch, 1-3 parts of a pigment and 2-4 parts of an additive. The master batch is PBS plastic. The additive includes the following components, by weight, 10-15 parts of a lubricant, 20-40 parts of a plasticizing agent and 5-10 parts of an anti-oxygen agent. The lubricant is one selected from barium stearate, fatty acid amide and monoglyceryl stearate. The plasticizing agent is one selected from DEHP, DOP and DBP. The anti-oxygen agent is an anti-oxygen agent 1010 or an anti-oxygen agent TNP. The PBS-based degradable plastic has both strong mechanical property and excellent stability, is not liable to generate harmful substances during use, and can be widely used in the fields of food package and living.

Description

Technical field [0001] The invention relates to a PBS-based degradable plastic. Background technique [0002] Degradable plastic refers to the addition of some additives to promote its degradation or the use of renewable natural raw materials to meet the application performance requirements during use and storage, and after use, under specific environmental conditions, the Within a period of time, its chemical structure will change significantly, causing loss of certain properties, or a type of plastic that has degradation properties when synthesized. Degradable plastics play a pivotal role in solving the global white pollution problem. [0003] As a multifunctional new technology material, biodegradable plastics have a wide range of applications and great market potential. According to relevant data, the consumption of biodegradable polymers in 2000 accounted for about 2% of the total plastic consumption, and the consumption reached about 4 million to 5 million tons. The United...
