Abstract

The invention relates to the technical field of degradable polymer materials, and in particular, relates to a waste biomass base degradation masterbatch, and a preparation method, an application and an application method thereof. The waste biomass base degradation masterbatch is prepared from the following raw materials in parts by weight: 5-25 parts of a waste biomass base, 5-15 parts of starch, 1-10 parts of a mineral powder, 0.1-3 parts of an ultraviolet photocatalytic degradation agent, 0.1-2 parts of an oxidation degradation aid, and 10-45 parts of biodegradable resin. With adopting of the application method, the waste biomass base degradation masterbatch prepared by the preparation method is used for degrading plastics and can be used for treating waste, that is to say, the waste biomass base can be used for degrading plastics which cannot be degraded, and an environmental-protection film product which can be used is prepared; and in addition, the application method is simple, and the raw material is the waste biomass base, so the cost for degrading the plastics is low.

Description

technical field [0001] The invention relates to the technical field of degradable polymer materials, in particular to a waste biomass-based degradable masterbatch and its preparation method, application and application method. Background technique [0002] As one of the most widely used materials, plastic has penetrated into many areas of the national economy and all aspects of people's lives. Plastic products such as agricultural mulch, packaging bags, plastic lunch boxes, shopping bags, etc. become plastic waste after use. Plastic waste is difficult to degrade in nature and forms "white garbage", which leads to environmental degradation and threatens human health. At present, these "white wastes" are mainly disposed of through landfill, incineration, recycling and pyrolysis liquefaction, which are expensive and inevitably cause secondary pollution. Plastic degradable technology is considered to be the most radical technology to cure "white pollution", and has become a res...
