AI Technical Summary

Problems solved by technology

Its material is generally filler-modified polypropylene, which has a certain UV aging degradation performance, and its strength decreases very quickly under light conditions, but a large number of polymer particles will be produced during the degradation process, especially non-woven fabrics. At about 5-15um, a large number of tiny fibers will be produced after breaking, which will cause certain harm when entering the human body, pollute water bodies and soil, and cause great damage to the environment.
At the same time, although polyolefin polymers are easily degraded by ultraviolet light after being modified by special additives, the polymers embedded in the soil are very difficult to be degraded by microorganisms, and the degradation cycle is generally as long as 50-150 years. Getting smaller, but increasing damage to creatures
[0006] In addition, although non-woven fabrics and shade nets have the functions of shading, protection, and water permeability, they cannot effectively prevent the evaporation of water, do not have the function of water retention, and cause damage to the environment

Abstract

The invention discloses a biodegradable intelligent water-permeable moisturizing film as well as a preparation method and application thereof. The biodegradable intelligent water-permeable moisturizing film comprises a shaping layer and a telescopic deformation layer; the shaping layer is a modified poly(adipic acid) / butylene terephthalate layer, and the telescopic deformation layer is a starch modified acrylate hydrogel layer compounded on the shaping layer; the telescopic deformation layer is swelled after absorbing water, and is recovered after being dehydrated; grooves distributed in an array mode are formed in the biodegradable intelligent water-permeable moisturizing film, and cross-shaped holes are formed in the bottoms of the grooves. The biodegradable intelligent water-permeable moisturizing film has the functions of water permeation, moisturization, water and soil loss prevention and vegetation maintenance and fertility enhancement, and can be used for ecological restoration or recovery of side slopes, landscaping, agricultural production and the like.

Description

Technical field [0001] The present invention relates to the field of ecological environment engineering, and more particularly to a biodegradable intelligent water moisturizing film and a preparation method thereof. Background technique [0002] China's landform is rich in form, complex terrain, and only 13.92% of vegetation coverage. Geological disasters happen frequently in my country. Since a large amount of soil erosion has caused serious hazards to ecology, it includes not only the impact on the environment, but also brought great troubles on people's lives and safety. The impact of geological disasters is reflected in all aspects of social life, including the harm to Jianghe Waterway, important railway road lines, important construction sites, etc., especially the construction of mining and reservoirs, the mines built around the mountain and Water conservancy projects built according to the mountain river terrain will have major safety hazards and safety incidents due to th...
