Abstract
The invention discloses a controllable full-biodegradable mulching film which comprises anti-hydrolysis layers, anti-aging layers and an insulating layer, and is characterized in that the anti-aging layers are arranged on the two sides of the insulating layer, and the anti-hydrolysis layers are arranged on the outer sides of the anti-aging layers. The mulching film has the benefits that the controllable full-biodegradable mulching film is biodegradable; the anti-hydrolysis property, the ultraviolet protection property, the heat resistance, the anti-oxidation property and the anti-aging property are good; and the service life can meet a requirement of a whole growth cycle of crop.
Description
Technical field
The invention belongs to agricultural film technical field, more specifically say a kind of controllable full-biodegradable mulch film.
Background technology
Agricultural mulching is the important means of production of modern agricultural production, not only there is moisturizing, water conservation, fertilizer conservation, insect protected, press down the functions such as grass, can also keep soil moisture, improve efficiency of water application, improve crop growth environment simultaneously, improve crop yield and agriculture benefit, therefore application is comparatively extensive.What the raw materials for production of the agricultural mulching of prior art adopted conventionally has two kinds: the one, and polyvinyl resin, the 2nd, Biodegradable resin.Adopt the agricultural mulching of polyvinyl resin in natural environment, self be difficult to decompose, use and cause broken film to accumulate on year by year soil plough horizon year after year, thereby cause soil compaction, and that soil compaction can cause is waterproof, airtight, root growth is obstructed, and causes the problems such as crop yield degradation and environmental pollution; The raw material that the agricultural mulching of employing Biodegradable resin adopts is generally resin poly butylene succinate, PHA, PLA, poly adipate succinic acid ester and mutual-phenenyl two acid bromide two alcohol ester's copolymer, although these Biodegradable resins possess fully biodegradable performance, but its resistant to hydrolysis performance, the poor-performing of uvioresistant, heat resistanceheat resistant, resist oxygen aging, the service life of product is shorter, is difficult to meet the requirement of the whole growth cycle of crops.
Summary of the invention
For addressing the above problem, the present invention has designed a kind of fully biodegradable, resistant to hydrolysis performance, uvioresistant, heat resistanceheat resistant, resist oxygen aging functional, can meet the controllable full-biodegradable mulch film of the whole growth cycle requirement of crops service life, its technical scheme is: described controllable full-biodegradable mulch film is comprised of anti-hydrolysis layer, anti-aging layer, heat-insulation layer, the both sides that it is characterized in that heat-insulation layer arrange anti-aging layer, the anti-hydrolysis layer of arranged outside of anti-aging layer.
Anti-hydrolysis layer of the present invention, it is characterized in that anti-hydrolysis layer is arranged on the outside of anti-aging layer, the material of anti-hydrolysis layer adopt the poly butylene succinate of 100 weight portions, the polycarbodiimide of the PHA of 30～50 weight portions, 1～6 weight portion, the erucyl amide of the superfine talcum powder of 3～15 weight portions, 0.2～1 weight portion.
Anti-aging layer of the present invention, it is characterized in that anti-aging layer is arranged on the both sides up and down of heat-insulation layer, the material of anti-aging layer adopts the mutual-phenenyl two acid bromide two alcohol ester of 100 weight portions and mutual-phenenyl two acid bromide two alcohol ester's copolymer, the PLA of 10～30 weight portions, the erucyl amide of the nano-calcium carbonate of 30～50 weight portions, 0.2～0.5 weight portion.
Heat-insulation layer of the present invention, the both sides up and down that it is characterized in that heat-insulation layer arrange anti-aging layer, and the material of heat-insulation layer adopts the mutual-phenenyl two acid bromide two alcohol ester of 100 weight portions and mutual-phenenyl two acid bromide two alcohol ester's copolymer, the PLA of 10～30 weight portions, the superfine talcum powder of the PHA of 20～50 weight portions, 3～10 weight portions, the phenyl salicytate of the erucyl amide of 0.2～1 weight portion, 0.5～1.5 weight portion, the citric acid of 0.3～1 weight portion.
The invention has the beneficial effects as follows that controllable full-biodegradable mulch film is biodegradable, resistant to hydrolysis performance, the performance of uvioresistant, heat resistanceheat resistant, resist oxygen aging is good, can meet the whole growth cycle requirement of crops service life.
