Problems solved by technology

Among them, foreign products are good in terms of mechanical properties and biodegradability, but they are expensive; while some domestic products also have many problems, such as the decline in mechanical properties, high production costs, and difficult control of degradation accuracy. Starch-based degradable plastics use starch from food production as raw materials, and conflicts between industry and people compete for food, etc.

Abstract

The invention belongs to the technical field of bio-based degradation, and relates to a functional adjusting master batch for biodegradation and a preparation method thereof. The functional adjustingmaster batch comprises the following components in parts by weight: 60-90 parts of carrier resin, 0.1-50 parts of degradation accelerant, 0.1-10 parts of heat stabilizer, 0.1-5 parts of light stabilizer, 0.1-5 parts of antioxidant, 0.1-20 parts of chain extender and 0.1-20 parts of other functional aids. The function adjusting master batch can effectively adjust degradation time and degradation speed, and has good anti-aging performance.

Description

technical field [0001] The invention belongs to the technical field of bio-based degradation, and relates to a function-regulating masterbatch for biodegradation and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the scale of petroleum synthetic plastics industry is also rapidly expanding, and plastic products are also used in more and more industries; specifically, the world's plastic consumption is estimated to be 335 million tons, and China's plastic consumption The volume is estimated at more than 70 million tons. Plastic products provide convenience for industry, agriculture and daily life, but at the same time generate a lot of waste. These wastes exist in solid form, and their sources are mostly disposable plastic products such as packaging bags, beverage bottles, and agricultural mulch films. There are many problems such as large volume, long decomposition time, and difficulty in degrading in the natura...
