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 includes 60-90 parts of PBAT, 5-15 parts of PLA / PBS, 3-8 parts of modified starch, 10-30 parts of modified biological calcium powder, 2-10 parts of EAA, 0.1-1 part of dispersant, 0.1-1 part of chain extender, 0.1-1 part of erucamide, 0.1-1 part of surfactant, 1-5 parts of glycerin / silicone oil. The membrane material is environmentally friendly and degradable, reduces environmental pollution, has high biodegradation rate, high strength and low 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, mulching is often used to improve the growth environment of crops. The mulching method has many advantages, such as effectively improving the utilization rate of crops to light, temperature, water, fertilizer and land, promoting the growth of plants, and increasing crop yields. Various packaging bags traditionally used in daily life have brought a lot of convenience to people, but it is difficult to discard and recycle with household garbage, which has caused serious pollution to the environment. Residues cause white pollution to the agricultural ecological environment. The currently used packaging films and mulching films are made of chemical fibers. The main components are polyethylene and polyvinyl chloride, which can remain in the field for decades wit...
