Problems solved by technology

Polylactic acid (PLA) is the biodegradable plastic with the best comprehensive properties developed in recent years. It has no pollution to the environment. It has good biodegradability and can be completely degraded by microorganisms in nature after use. Generates carbon dioxide and water, does not pollute the environment, and meets the requirements of environmental protection in today's world; however, the crystallization of polylactic acid is slow, the ester bond energy in the molecular chain is small, and it is

Description

technical field [0001] The invention relates to the technical field of biodegradable materials, in particular to a biodegradable material and a preparation method thereof. Background technique [0002] The problems of environmental degradation and resource shortage in the world are becoming more and more prominent, and the pollution of the environment by ecological solid waste and the waste of resources caused by it are becoming more and more serious. With the continuous improvement of economic development and people's living standards, the discharge of solid waste has increased sharply. It is estimated that the world adds about 10 billion tons of solid waste every year, or 2 tons per capita. The increasing solid waste has brought great challenges to the human living environment and has become one of the main factors of environmental pollution. [0003] Plastic is widely favored by people for its light weight, waterproof, corrosion resistance, high strength and other excel...
