Problems solved by technology

The agricultural mulch film using polyethylene resin is difficult to decompose in the natural environment. Years of use will cause the broken film to accumulate in the soil layer year by year, resulting in soil compaction. The serious decline in crop yield and environmental pollution and other problems; the raw materials used in agricultural mulch films using biodegradable resins are generally resin polybutylene succinate, polyhydroxyalkanoate, polylactic acid, polybutylene adipate And butylene terephthalate copolymers, although these biodegradable resins have complete biodegradability, their hydrolysis resistance, UV resistance, heat resistance, and oxidation resistance are poor, and the service life of the product is short , it is difficult to meet the requirements of the entire growth cycle of crops

Abstract

The controllable fully biodegradable mulch film is composed of an anti-degradation layer, an anti-aging layer and an insulation layer. The fully controlled biodegradable mulch film is biodegradable, has good hydrolysis resistance, anti-ultraviolet radiation, heat resistance, and anti-oxidation aging performance, and its service life can meet the requirements of the entire growth cycle of crops.

Description

technical field [0001] The invention belongs to the technical field of agricultural films, and more specifically relates to a controllable fully biodegradable film. Background technique [0002] Agricultural mulch film is an important means of production in modern agricultural production. It not only has the functions of moisturizing, water retention, fertilizer retention, pest control, and weed control, but also can maintain soil moisture, improve water use efficiency, improve the growth environment of crops, and increase crop yield and agricultural benefits. , so it is more widely used. There are two kinds of raw materials for the production of agricultural mulch films in the prior art: one is polyethylene resin, and the other is biodegradable resin. The agricultural mulch film using polyethylene resin is difficult to decompose in the natural environment. Years of use will cause the broken film to accumulate in the soil layer year by year, resulting in soil compaction. T...
