Abstract

The present invention relates to the technical field of biodegradable plastic films, particularly to a special pbs modified biological fully-degradable film material, which comprises the following raw materials by weight: 5-30 parts of polylactic acid, 20-40 parts of starch, 40-60 parts of polyadipic acid / butylene terephthalate, 0-20 parts of lignocellulose, 0-1 part of an antioxidant, 2-10 parts of a melt reinforcing agent, 5-20 parts of a starch modified plasticizer, and 0.1-10 parts of a coupling agent. According to the present invention, the special pbs modified biological fully-degradable film material is disclosed, the film prepared from the special pbs modified biological fully-degradable film material has advantages of excellent mechanical property, excellent thermal stability and excellent film uniformity, the prepared special pbs modified biological fully-degradable film material belongs to the completely biodegradable material, can solve the white pollution problem caused by the plastic, and belongs to the environmentally friendly material, and the prepared plastic film has the high bio-base content, has advantages of low cost and environmental protection, and has great industrialization advantages at home and abroad.

Description

technical field [0001] The invention relates to the technical field of fully degradable materials, and is a special material for PBS modified biodegradable film. Background technique [0002] At present, as a commonly used material, plastic film plays an increasingly important role in daily industrial production and life, especially in the fields of automobiles, home appliances, packaging, agriculture, telecommunication and electric power, etc., showing an increasing trend year by year. However, with the increase in the amount of plastic film, the problems caused by waste plastic film are also emerging one after another. Whether discarding, landfilling or burning waste plastic film will cause great damage to the environment. Therefore, research on degradable plastic film has been carried out in recent years. become a hot topic. The common modification method of degradable plastic film is to use polyolefin as raw material and add certain biodegradation additives to achieve d...
