Problems solved by technology

[0003] At present, natural materials such as starch, protein, and cellulose are often used as raw materials for degradable plastic films. In addition to high costs, they will also have adverse effects on people's livelihood, and the promotion process is extremely difficult; at the same time, the existing biodegradable plastic films and packaging films have low toughness. Poor and cannot be better applied to the field of agricultural mulch

Abstract

The invention belongs to the technical field of biodegradable materials, and relates to a biodegradable film material. The film material comprises 60 to 90 parts of PBAT, 5 to 15 parts of PLA / PBS, 3 to 8 parts of modified starch, 10 to 30 parts of modified biological calcium powder, 2 to 10 parts of EAA, 0.1 to 1 part of a dispersant, 0.1 to 1 part of a chain extender, 0.1 to 1 part of erucyl amide, 0.1 to 1 part of a surfactant and 1 to 5 parts of glycerin / silicone oil. The film material is green, environmentally friendly, degradable, capable of reducing pollution to the environment, high inbiological decomposition rate, high in strength and low in cost.

Description

technical field [0001] The invention belongs to the technical field of biodegradable materials, and relates to a biodegradable film material. Background technique [0002] In the process of modern agricultural production, plastic film mulching is often used to improve the growth environment of crops. The method of mulching with plastic film has many advantages, such as effectively improving the utilization rate of light, temperature, water, fertilizer and land of crops, promoting the growth of plants and increasing the yield of crops. Various packaging bags used in traditional life have brought people a lot of convenience, but it is difficult to discard and recycle them with domestic garbage, causing serious pollution to the environment. With the widespread use of plastic film and packaging film, packaging film and plastic film are also brought Residues cause white pollution to the agricultural ecological environment. The packaging film and mulch film currently used are mad...
