Description

High-temperature-resistant degradable plastic material

Technical Field

The disclosure belongs to the technical field of plastic materials, and particularly relates to a high-temperature-resistant degradable plastic material.

Background

The plastic product becomes an indispensable daily necessity in daily life of people and is seen everywhere in production and life. Compared with metal, stone and wood, the plastic product has the advantages of low cost, strong plasticity and the like, is widely applied in national economy, has an extremely important position in the current world in the plastic industry, and is developed at a high speed all over the world for years. The fields of application and the territory of plastics are becoming more and more widespread due to the properties exhibited by plastics themselves, such as light weight, excellent chemical stability and electrical insulation, and poor thermal conductors.

At present, plastic products are consumable in daily life, and a large amount of plastic products are consumed every year. While the plastic products provide convenience, serious energy resource waste and environmental pollution are caused due to excessive use, improper recovery treatment and the like. Especially, the ultra-thin plastic packaging bag is easy to be damaged and is mostly discarded at will, which becomes the main source of 'white pollution'. More and more countries and regions have limited the production, sale, and use of plastic packaging bags. People begin to take powerful measures from the source, research and develop novel durable and easily degradable plastic products, but the developed degradable plastic products all have the problem of poor heat resistance, and are easy to distort under the condition of contacting high temperature.
