Abstract
The utility model relates to a high-lighting-effect light conversion film. The high-lighting-effect light conversion film is characterized by comprising a three-layer co-extrusion composite film structure, wherein the three layers are an outer layer, a middle layer and an inner layer; the outer layer is a mechanical characteristic layer; the middle layer is a light conversion layer; and the inner layer is a drip fog-clearing layer. The high-lighting-effect light conversion film has the advantages that: the film has different functions according to different layer structures, so that the film has high strength, high impact resistance, high tear resistance, high heat-preserving property, high light transmission property and excellent drip fog-clearing performance; and a high-strength rare earth multifunctional light conversion agent is added into the film and can excite and convert harmful light wave and invalid light wave into light wave beneficial to photosynthesis and growth of crops, so that the photosynthetic intensity of the crops is improved, heating and high yield are realized, the growth period of the crops is shortened, the using amount of pesticides is reduced, the vitamin content, the sugar content and the dry substance content of the fruit of the crops can be increased obviously, the quality of the crops is improved, and the light fertilizer effect is achieved. The high-lighting-effect light conversion film is particularly suitable for the growth requirement of thermophilic vegetables, melons and fruits with long illumination time and high illumination intensity.
Description
Technical field
The utility model belongs to agricultural film manufacturing technology field, particularly relates to a kind of high light efficiency conversion film.
Background technology
At present, the low density polyethylene (LDPE) plastic sheeting for farm use has been widely used in the cultivation and the field of planting of vegetable melon and fruit and flowers and other crops, and it can be those and receives ecological factors such as temperature, humidity and light to influence bigger crop growth conditions preferably is provided.But because the growth conditions of various crops is different, some crop need could well grow down by environment long in light application time, that intensity of illumination is high; In China's sunshine-duration short area or the area of rainfall often; Natural lighting in the greenhouse and temperature are obviously not enough, cause vegetable melon and fruit and flower growth slow, and then influence product quality; Therefore, above-mentioned low density polyethylene (LDPE) plastic sheeting for farm use is difficult to satisfy the growing environment needs of happiness temperature type vegetable melon and fruit crop.
Summary of the invention
The utility model provides a kind of high strength, high impact properties and high tear resistance for solving the technical problem that exists in the known technology, and has the high light efficiency conversion film of high insulation, high printing opacity and good drip fog dispersal performance.
This high light efficiency conversion film utilizes the photoproduction attitude principle of the multi-functional light conversion agent of high strength rare earth; Can harmful light wave in the spectrum and some invalid light wave be excited and be converted into the light wave useful with growth the crop photosynthesis effect; Thereby improve the crop photosynthesis action intensity, reach heat, high yield, shorten crop growth period and the use amount that reduces agricultural chemicals and chemical fertilizer; Can significantly improve vitamin in the crop and fruit, sugar part and dry matter content; Promote crop quality, play the fertile effect of light, be particularly suitable for the growth needs of the happiness temperature type vegetable melon and fruit crop that light application time is long, intensity of illumination is high.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
High light efficiency conversion film is characterized in that: it comprises the three-layer co-extruded structure of composite membrane of skin, middle level and internal layer, and said skin is the mechanical characteristic layer, and the middle level is a conversion layer, and internal layer is a drip fog dispersal layer.
The utility model can also adopt following technical scheme:
The gross thickness of said high light efficiency conversion film is: 70-150 micron, its density are the 0.935-0.980 grams per cubic centimter.
The thickness of said skin, middle level and internal layer is equal thickness.
Said skin is 25% of a gross thickness, and said middle level thickness is 40% of gross thickness, and said internal layer is 35% of a gross thickness.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Promptly skin, middle level and internal layer are through three-layer co-extruded blow molding process one-shot forming; The photoproduction attitude principle of utilizing light conversion agent in the film excites harmful light wave in the spectrum and some invalid light wave and is converted into the light wave useful with growth to the crop photosynthesis effect; Improve the crop photosynthesis action intensity; Utilize heat preservation principle and the drip agent of heat preserving agent, the hydrophily of antifogging agent to make film have high heat insulating ability, high light transmittance and good drip fog dispersal function simultaneously, make the vertical, horizontal mechanical property of goods even.Three layers of compound high light efficiency conversion film that process have high strength, high impact properties and tear resistance; Prolonged film service life simultaneously; To industrial crops such as green non-pollution gourd, fruit and vegetables a good growing environment is provided; Further improve and improve crop photosynthesis speed, the enhancing crop resistance against diseases shortens crop growth period.All production process can not produce any harmful substance, non-environmental-pollution.Product after the use can all reclaim makes other plastic products, has promptly practiced thrift petroleum resources, has formed the technology path that economy capable of circulation is characteristics again, reduces user's use cost greatly.
