Problems solved by technology

The accumulation of waste plastic products mixed in the soil will affect the absorption of nutrients and water by crops, resulting in reduced crop production and affecting agricultural development
Due to its extremely difficult to decompose, landfill treatment will not only occupy a large amount of land, but the occupied land will not be restored for a long time, which will affect the sustainable use of land; if it is disposed of by incineration, it will cause serious air pollution.
In recent years, the development and application of environmentally friendly plastic materials with agricultural product starch as the main component have gradually emerged. However, this material has a fast decomposition rate, weak oxidation resistance, impact resistance, and strong water absorption.

Abstract

The invention discloses an environment-friendly plastic material which comprises the following raw materials in parts by weight: 20-25 parts of polycaprolactone PCL, 65-70 parts of modified poly-beta-hydroxybutyric acid PHB, 13-18 parts of peanut protein flour, 1.5-1.8 parts of jute fiber, 3-4 parts of wood fiber, 1.1-1.3 parts of a silane coupling agent KH, 2-3 parts of sodium lactate, 1.1-1.6 parts of sodium diacetate, 2-2.2 parts of diisononyl phthalate, 5-7 parts of epoxy tall oil acid butyl ester, 2-4 parts of oxidized starch, 20-23 parts of nano white carbon black, 6-8 parts of light calcium carbonate, 3-5 parts of sea-foam stone powder and 1-1.4 parts of an antioxidant 1010, wherein the modified poly-beta-hydroxybutyric acid PHB is prepared by blending and modifying poly-beta-hydroxybutyric acid PHB and high cis-butadiene rubber. The environment-friendly plastic material can be degraded by microbes and is low in decomposition rate, high in oxidation resistance and impact resistance and low in water-absorbing quality.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to an environment-friendly plastic material. Background technique [0002] Plastic materials are widely used, such as toys, plastic bottles, packaging bags, shopping bags, etc. We cannot live without plastics. However, as we all know, ordinary PP / PE plastics are difficult to decompose in the natural environment for hundreds of years, so discarded plastic products - also known as "white garbage" - are recognized as substances that can cause great damage to the environment. The accumulation of waste plastic products mixed in the soil will affect the absorption of nutrients and water by crops, resulting in reduced crop production and affecting agricultural development. Due to its extremely difficult to decompose, landfill treatment will not only occupy a large amount of land, but the occupied land will not be restored for a long time, affecting the sustainable use of land; i...
