Problems solved by technology

Plastic bags do bring convenience to people's lives, but the convenience at this moment brings long-term harm.
[0003] Generally speaking, the hazards of non-degradable popular plastics to the earth include: 1. Plastic bags have low recycling value and are easy to be scattered on city streets and tourist areas during use. The plastic structure is stable and not easily degraded by natural microorganisms , do not separate for a long time in the natural environment
This means that if waste plastics are not recycled, they will become pollutants in the environment, exist permanently and accumulate continuously, which will cause great harm to the environment.
2. Affect agricultural development
3. Waste plastic products discarded on ...

Abstract

The invention discloses a biodegradable medical packaging material and a preparation method thereof. The material comprises the following components: PE, PVC, an antioxidant, an auxiliary antioxidant, ethanediamine, a polyester fiber, gelatin, lecithin, polypropylene, polylactic acid, sodium starch, glycerin, emulsified silicone oil, succinic acid and chitosan. The preparation method comprises the following steps: adding PE, PVC, ethanediamine, the polyester fiber, gelatin, lecithin, polypropylene, sodium starch and chitosan to a reaction kettle; stirring and reacting under a vacuum condition at certain temperature to obtain a mixture 1; adding the residual components to the mixture; stirring and mixing evenly; and extruding and molding in a twin-screw extruder, so as to obtain the biodegradable medical packaging material. The biodegradable medical packaging material disclosed by the invention has good mechanical properties and biodegradable properties, and can be widely applied to the field of packaging.

Description

technical field [0001] The invention belongs to the technical field of medical material preparation, and in particular relates to a degradable medical packaging material and a preparation method thereof. Background technique [0002] At present, China's annual output of plastics is 3 million tons, and its consumption is more than 6 million tons. The annual output of plastics in the world is 100 million tons. If calculated according to the annual plastic waste of 15%, the annual plastic waste in the world is 15 million tons. The annual plastic waste in China is more than 1 million tons. The proportion accounts for 40%. Such a large amount of waste plastics are buried in the ground as garbage, which will undoubtedly bring greater pressure to the lack of arable land. While plastics bring convenience to people's lives, they also bring troubles to the environment that are difficult to deal with. People call the disasters brought by plastics to the environment "white pollution". ...
